Answer . I have a 1992 Plymouth Sundance with 130000 miles. 4 cyl, 2.0L It has been well taken care of with regular maintenance between 3k to 5k intervals since I bought it with 58k.. The car instantly overheats when turned on. The heat blows frigidly cold air. It has a thermostat that is ~5 mon…ths old. The car will shudder and shake and then cut out when left idling or when it over heats. It is not losing coolant, but the car smells like burning antifreeze when you lift the hood. It will also steam and or smoke that escapes from under the hood when you turn it on.. 1.) What are the possible diagnoses?. 2.) How much will it cost? (Chicago area). 3.) Is it worth spending the money on a rebuilt car that I've had since high school, or should I just give up and buy a newer car?. Answer . The most common cause of simultaneous engine overheating and no heat from the heater is extremely low engine coolant level, in other words a large pocket of air in the system. In some cars it's fairly easy to get the air out, in others it's very tricky. If there's a leak causing coolant loss, that will also have to be addressed or the problem will recur/worsen.. Answer . Check 1. Your Thermostat (70%) of the time it is your thermostat. 2. Check and see if your radiator is clogged (Also very common). . Another issue is if your car overheats during idle, then it could be the electric radiator fan. . ( Full Answer )
You didnt say if the water pump was changed. No hot air means no circulation. Answer Brittany, You have 2 symptoms of a larger problem. It is like you said "I have a terrible headache and black eye." What happened was you missed the ball and it cracked you in the head. Anyways, Coolant is a fluid …that keeps a car from getting too hot among other things. If there is low coolant the car will overheat. When the coolant ciculates through the engine it will also go through a thing in the dash that is like a small radiator called a heater core. A fan or blower move air through this part and pushes the hot air from the heater core into the passenger compartment. This heater core is usually the highest point of the coolant flow. Since fluid seeks it's lowest level, the heater core is the first to lose the hot coolant. Therefore your blower blows accross a cold heater core and gives you cold air. If you don't have a leak, then when the thermostat was replaced, the coolant may have not been bled of the air in the system. I would first fill the coolant and check for any leaks first. There is a common problem with the Buick centuries if you have a 3.1 motor. The intake manifold gasket is common for leaking. In any event, don't run the engine if it goes into the red. Overheating can cause headgasket problems. See othe posts regarding this issue. Let me know how you make out. Answer Glad to hear your problem was resolved. The heater core does not need to be removed to be checked. If the hose going into the heater core is hot and the one coming out is cold, the tells you it is retricted. Another way to verify is to remove the hoses going to the core, hook up one without installing into the car and run it. It should get hot-very hot, and then see how hot the hose is coming out of the core is like now. Answer If this person that replaced the thermostat put it in backwards this could cause the car to overheat and the heater not to get hot. EzForJesus Answer Simple - It is low on radiator fluid (water or anit-freeze). ( Full Answer )
Why would a Pontiac Sunbird only blow cold air when the heater is on and the temperature gauge run super hot but the car does not overheat?
It sounds to me like the heater core is out. Have you noticed the floor wet recently? that's a sure sign of heater core issues. The other option is it will act like that if it has no antifreeze or water in the radiator, in other words the radiator is dry. Just a suggestion if someone has replaced …the thermostat its possible they installed it pointing in the wrong direction this could account for cold air and the guage reading over hot. , EzForJesus ( Full Answer )
Why would a 92 Ford Taurus that was started occasionally but not driven for a few months now overheat slightly when you drive it it and the heater does not produce any heat?
Answer . \nthe thermostat is probably not functioning properly...replace thermostat and see if the situation is resolved. Easy cheap fix.. Answer . \nCheck your coolant level before replacing the t-stat. You may just be low on coolant.
Answer . \nYou may have an air pocket trapped from the work, t-stat may be stuck, anti-freeze may be too concentrated or too thin.. Answer . \nare you sure it was your heater core. does your coolant keep emptying from your surge tank?
You have a 1998 ford explorer 40l sohc it quickly starts to overheat what is the problem you've checked the heater hose and it is hot so this possibly eliminates the thermostat whats wrong?
The thermostat could still be the problem. It could be partially open, allowing some coolant through but not enough to cool the engine. It could also be a partially blocked radiator. Is the vehicle blowing out all of the coolant when it overheats? If so, it could be a head gasket or cracked head or …block throwing excessive pressure into the coolant, and causing everything to blow out the overflow. My problem was the head gasket. I understand that there is a clover test (possible mechanic nick-name for the procedure) that tests for CO2 in your coolant; an indicator of a blown head gasket. The Ford service dept power flushed my coolant five times before doing this test... wasted time. FYI, symptoms were overheat within the first 4-5 miles, then good flow the remainder of the trip. I thought the thermostat was not opening soon enough, but apparently CO2 gets in the coolant to cause a vapor lock before engine temp seals the gap. A word to those that read this... power flush your coolant annually to avoid coolant breakdown and corrosion of your head gasket. Good luck. Answer You're indicating that the HEATER hose is hot, but what about the radiator hose. The heater hose circulates constantly, but the thermostat can stop or almost stop flow through the radiator hose. Check that one too. If the radiator hose isn't getting very hot, it's almost certainly the thermostat. Now on to more mundane suggestions: whenever you flush your radiator, make sure that you either use pre-mixed coolant or get some distilled water for mixing. You don't want mineral build-up in the cooling system. Also, if you're getting carbon monoxide (CO) in the cooling system it's caused by either a damaged head gasket, cracked head or cracked block. The head and block are far more serious, but fortunately, not as likely among US built vehicles, especially V8's and 6's. But if the head gasket IS leaking, you can bet heavily on the head being warped. Don't even attempt to replace the head gasket without having the head resurfaced. ( Full Answer )
Problem with overheating Replaced cooling fan relay Overheats in stop and go driving heat comes out the heater but will car starts to overheat cold air comes out Any clue what could be Thermostat Plea?
Answer . \n. \n. \n. \n. \n. \n. \n. \n. \n. \n. \n. \n. \nEngine overheats \n. \nWhen a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is… full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system. Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps will solve the problem. ( Full Answer )
Answer . On the passenger side of the engine just ahead of the alternator, under the edge of the plastic engine cover there is a sensor with a plug and wires coming out of it, it says sensor pressure on it.That entire unit twists off and the pcv valve is under it
If a 1998 Mazda 626 will start and run for a little while but then overheat and die and you have changed the cooling fan and the transmission has been checked what else can it be?
Answer . \nIt could be any number of things, but I'd check for bad fan relay or fuse, sticking thermostat, blocked radiator or blown head gasket.
Why does the heat blower not work on a 2003 Monte Carlo when you first start up but will work after the car runs for a while?
\n. \n Answer \n. \n. \nThe engine should begin producing heater output within the first minute. Might take a little longer in colder climates.\n. \n Answer \n. \n. \nAlthough it sounds like I may not be warming my car up before turning on the heat blower, this never happened until a… month ago. Even if there is no heat, shouldn't it at least blow cold air? Nothing blows....what could it be?\n. \n Answer \n. \n. \nIf the BLOWER(FAN) is not blowing no mater what speed or settings are used on the climate control center(AC,DEFROST), the the motor itself is bad. A good test is to take a ruber malet and lightly smack the motor directly with the engine running. If the motor suddenly starts blowing then the motor is bad. About $110.00 to replace with common hand tools. ( Full Answer )
Vehicles won't start when overheated. Alot of vehicles act this way as a safety mech. to help protect your engine from damage. At a certain temp. the factory ECU disengages the ignition.
your a/c fan is not kickin on! get 12 volts to the fan to see if it works! if fan works check fan relay
Why would a 95 Monte Carlo start occasionally but not consistent When it does start everything runs fine What could be the problem?
Answer . \nRemember the number one problem with these cars is fuel pump related. Check your fuel pump pressure; your pump may be getting weak.
Answer . \nyour a/c unit works your engine harder then not running it. it should not make it over heat, but if it does, check your antifreeze/ water mix in your ratiator, if the level is too low, this may be your problem, if it is fine, check your fan, make sure it is running correctly, you shou…ld hear it come on when your engine is getting hot. if this is also working fine, heck your radiator and make sure the fins on it arent bent in any way, a few bends are ok, but if 1/4 or more of it are bent, get a different radiator, lastly, check and make sure you dont have bugs clogging your radiator (this has happened to me) ( Full Answer )
Answer . Check the thermostat or the radiator. The thermostat could be sticking or the radiator could be plugged.
It is a tough job, you will need to remove your front seat, it will be nearly impossible if you don't have all the room that you will need. It will be difficult to work with the front seat in place but, if you do it, it can be done. I say remove the seat because it will be much easier to work withou…t it. there are only four bolts holding it on anyhow. Okay, let's get down to it. You will need to remove your inner fender skirt (the plastic fender)You will need to remove all the bolts and or nuts holding your fan blower cover to the firewall, there are either eight or nine to remove. After those are removed, take off the housing, also take off the ground and your realay switch,go to the interior of the car and wiggle the interior plastic housing loose, now comes the tricky part, there are small screws holding an aluminum cover over the heater core, remove all these small screws, also remove any rubber grommets, now wiggle that loose, you can use a screw driver to get it loose where it is stuck, DON'T force it, now reach in a pull out the heater core, go in reverse to put it back together. Hope this helps, I just did one myself. ( Full Answer )
Car starts to overheat when idling and heater does not blow hot air radiator fan does not kick on when car heats up what could be the problem?
Answer . either the thermostat or the fan is no good. You would need to locate the thermostat and see if its stuck open or closed!
96 Chevy Monte Carlo will not start engine doesnot turn over with key can jump start at starter with key in run position will start for two seconds and stall?
I am having same issue with mine I was thinking it is passlock i was told to take to dealer and have body control module re flashed , but I was also told it could be fuel pump not allowing car to start
You should check your water level. It's low, and you have a leak.Get someone to check it for you. . The heater in your car works off the water from your radiator, nowater in the radiator will over heat the engine ergo top up thewater. . Could also be low antifreeze level causing water in radiato…r tofreeze making the engine overheat and the heater to blow coldair. . You have an airlock. . If you have a system with expansion/filler tank then check thereturn pipe is not blocked. . These systems bleed themselves if there are no blockages. Mine was because the impeller in the water pump had disintegratedto the point where it would not move the water. The water wouldoverheat, but the hot water would not get moved into the heatercore to blow hot air. I replaced the water pump and it all worksnow. . ( Full Answer )
It could do. DOn't let it run lean. It's very uneconomical and bad for the engine.
Why does your car overheat when running lack power at high speed difficult to start and idle erraticly?
sounds like the timing is wrong.also need to do compression check for blown head gasket or cracked head.
This is might also be the time to check your cooling system for any possible leaks. A leaking heater core in the winter time can be dangerous, because you are exposed to the coolant fumes in a closed environment. If you suspect a leaking system, drive with fresh air coming in from your vents or a wi…ndow slightly open. ( Full Answer )
generally if an engine overheats, but then does not overheat when heater is turned on, is a good indication that the engine thermostat is stuck and needs replacing
A leaking heater core will cause the engine to overheat because the coolant is leaking out.
1997 Chevy Monte Carlo that is over heating it quit when your defroster started workin but now my heater and defroster stopped working and my car is running hot what could be the problem?
There are many reasons why an engine overheats. It can be as simple as adding coolant and water to having a cracked head or heads. You need to look at your cooling system. Check the level of your cooling fluid. Add if it is low. Then check your radiator hoses to make sure they are not collapsing whe…n the motor is warm. You may have a weak water pump or thermostat. There can even be a blockage in the radiator or cooling system that causes overheating. You need to check them all and search down the reason. ( Full Answer )
It could be any number of things, but here's what to check... Make sure the radiator is full of coolant (with the engine off and ice cold, facing slightly uphill) If you need to add coolant start the car (with radiator cap removed) and add coolant while its running directly to the radiator. On…ce the radiator is full replace the cap then add coolant to the reservoir. If coolant is not an issue, then make sure the fan is coming on when the car is trying to overheat...a dead fan or bad solenoid to make the fan run is very common on newer cars, older cars used a directly attached fan that always ran with the engine on. Next thing to check is the termostat, if the car starts to overheat and the top radiator hose is hot and obviously coolant isn't circulating through it then a bad t-stat is to blame. It could also be a bad water pump; however, under normal circumstances it would leak a small amount of water from a "weep hole", the location of the water pump varies slightly with vehicle. Lastly you could have a blockage in the radiator requiring repair from a reputable shop or replacement (which is usually cheaper, if you're the one doing it). Good luck! ( Full Answer )
First thing to inspect is that there is enough anti-freeze / coolant. If the coolant level is full, then this sounds like a symptom of a failed water pump. Although the pump may not be leaking, the impeller may not be spinning and moving the coolant through the engine.
Theres a couple of things that can cause this. First, check ALL the hoses to be sure you dont have a leak. make sure the radiator and reservoir are not leaking. Then you need to check the thermostat. The easiest way i know to do this is run the engine to normal temp, providing you can do this withou…t overheating. there are two hoses coming out of your radiator, one is coolant to the engine, one is the warm coolant back to the radiator. Touch them both, CAREFULLY DO NOT GET BURNT or hurt by any other engine parts such as the engine fan!. if one of them is WAY cooler than the other your thermostat is stuck and you need to replace it. You may have a head gasket blown,if you are losing coolant and do not see any puddles, like this coolant has "mysteriously vanished" get this checked out! another possibility if your heater core is shot, if its not the thermostat, your hoses are all intact and your radiator and reservoir are not leaking, this is likely your problem. OR, you may have a water pump problem, if you have a large puddle under your engine, not near the radiator, get this checked by a professional mechanic ASAP. you can cause serious damage running a car hot.

What do I do when my 1993 Lincoln MarkVIII has no overdrive and the care overheats and leaks small amount of coolant from firewall next to Accumulator but is not where the heater core hoses lines run?
With the overdrive, if it was working and just quit, probably the wire in the shifter. As for the leak you will just have to trace. Maybe the coolant is running under the hose and at the lowest point is dropping where you see it. Sorry couldn't help much.
There is oil in my radiator in my 02 Chevrolet Monte Carlo but it doesn't overheat What wrong with it?
Check to see if there is coolant on the engine block. It is common for the Monte Carlos, along with other GM cars equipped with the 3400 V6 engine to experience leaking intake manifold gaskets. A leaking intake manifold will cause oil to leak into the coolant system and even worse, for coolant to le…ak into the oil system. ( Full Answer )
2002 impala still over heats even after replaced water pump heater core thermostat radiator and even used blue devil sealant car runs fine till you drive it then it overheats?
After replacing all of the above items on this vehicle, there may be only a few answers left. You may have a blown head gasket(s). The engine will overheat no matter what with that. Also look at your hoses, sometimes a hose will be weak only under pressure and collapse as to block the water flow.
Because the engine is too hot to continue cycling correctly without the pistons "sticking" against the side of the cylinders, causing them to slow down or even stop moving in extreme cases. buy some antifreeze
Most of the time it is because the thermostat has gone bad and is not opening at the proper temperature. Cure: replace thermostat.. If the thermostat has been replaced, flush the radiator. Buildup of residue in the bottom of the radiato0r will cause overheating, but it is maintained over heating, n…ot temporary. ( Full Answer )
What would make your 1999 buick century go to the red in overheat and the heater start throwing out cold air you have replaced the water pumpradiatorradiator cap and thermostat?
\n. \nIs the cooling fan working as it should? Another possibly is air trapped in the system. Remove the radiator cap, set the heater to hot, start the engine and watch for air bubbles escaping from the radiator. Keep it topped of while doing this, and when you see no more air bubbles, put the cap …back on and shut it down. ( Full Answer )
In the general case, cars overheat because of a bad thermostat, low coolant level, blockage in the coolant system, insufficient antifreeze percentage, fan blockage, or water pump failure.
\nNo, a clogged heater core will not make it overheat. A leaking heater core will.
What would make 94 apv Chev constantly start to overheat in stop and go driving but run cool on highway?
If it has a thermo(electric) radiater fan, check that it is working, by connecting it directly to the battery, and if it works, it's probably not switching on when the temperature rises, so the thermo switch will be faulty.
For both your heater and air conditioning not to work means you either broke a belt or the belt is loose.. Overheating would also be caused by this, because your water pump is driven by the same belt.. Do not drive it until you get it fixed, you'll kill that engine by overheating it.
Assuming your spark plugs and wires are in good shape, put a checker on the diag harness and look for a bad speed sensor. could be many other things however - sorry but sketchy info. Good luck.
Can a run capacitor start a blower motor running it slow and causing it to overheat or is it a bad motor?
Yes, a bad capacitor causes blower motor to become slow or stop. Since bad or short capacitor will make the surge of current and tripping of circuit breaker.
Why would a 1996 dodge grand caravan overheat if sitting in traffic with ac running but cool off when you turn it off or start driving faster?
The radiator fan is not working,or not working properly,or possibly the thermostat is bad.But,usually if the thermostat is bad the engine would still overheat even if you speed up,so I would suggest testing the radiator cooling fans.
You are probably very low on coolant. If so you have a leak somewhere. Have it check by a mechanic now before you damage the engine if you haven't already.
It is possible that your radiator is partially plugged or the heater core is leaking coolant or the thermostat is the wrong temperature. Sorry for so many scenarios, but I have seen all of these.
Probably any normal thing like not enough Radiator Fluid or something is wrong with your radiator or a head gasket leak could cause the radiator fluid loss. Does this Help?

Ok you have a 00 Montana 3400 you have replaced the thermostat 2xs water pump 2xs front heater core radiator intake gastket and flushed the rear heater core and it still overheats?
I don't know how old this question is, but we had a similar problem, it turned out a head gasket was leaking. We've had it replaced and the van has been driven about 500 miles since then without overheating. I'm sure that's not what you wanted to hear, but I would find out if that's the case with yo…urs too. ( Full Answer )
Does the computer also say low coolant. On start-up mine did that so I'm pretty sure it does that to make sure you check that the coolant level is ok. If coolant level is good then the thermostat is probably stuck open.
Yes it can cause it to overheat but first check your thermostat. That would be the 1st cheapist thing to do before you did anything else. I got an 85 regal(overheating) and the thermostat or the heater core is the problem im getting them both replaced tomorrow and will let know of how it runs.
In the general case, cars overheat because of a bad thermostat, low coolant level, blockage in the coolant system, insufficient antifreeze percentage, fan blockage, or water pump failure.
Don't know the year, make or model of your vehicle but start with replacing the thermostat then check to be sure the fan clutch is working properly and that the fan shroud is there and in one piece. The radiator may also be plugged up, a cooling system flush may help.
