Antifreeze and Engine Coolant
All internal combustion engines generate heat. To regulate the temperature of the engine, an engine cooling system, usually a water-cooled system, removes the heat. Antifreeze liquid solutions are added to prevent ice build-up in these systems at cooler temperatures.

Should your 96 intrepid be runnung when adding antifreeze?
No , the engine should be cool before adding any fluids to the engine cooling
system
Where is the ECT sensor located on a 2001 Chrysler Town and Country?
It is located behind on the opposite side of the block(the side toward the dashboard) where the upper radiator hose connects. You have to loosen (NOT completely remove) the power steering resevoir, and completely remove the ignition coil (where all the spark plug wires connect) and the mounting plate underneath to get to it. I bought a haynes repair manual that contained good printed advice for the proceedure, but the picture doesn't help much. It was worth the twenty dollars for the manual, though.
What do you put in the coolant reservoir?
If the reservoir is low, ad a 50/50 mix of coolant and water. Or, buy it premixed and ad as is.
What is the normal operating temperature of a 1993 Jeep Cherokee?
Hey Robert==It should run from about 140 deg to 230 deg. Over about 260 deg. can harm the engine. Good luckJoe
The Thermostat is 210 deg - mine always runs within 10 deg.s either direction with the exception of heavy stop and go traffic will cause it to be higher.
What antifreeze do you use in a Porsche Boxter?
Use Porsche antifreeze. Get it from the dealer or online.
Losing coolant and oil is milky?
You've got a leak between the cooling system and the oil, most likely a blown head gasket.
Why is 1997 Toyota Avalon leaking antifreeze?
How do you add antifreeze fluid?
50/50 water and Anti-freeze mixture into a cold radiator or coolant tank. DO NOT open cap on a warm radiator as it may expell scalding water.
It is critical that you know what kind of antifreeze your car takes. There are 2 general kinds. Long life and traditional Green coolant. The sensors base data on the correct chemical composition of the one that was originally installed in it. Therefore adding wrong one may cause the ecm to adjust the fuel mixture incorrectly or cause sensor damage. Some vehicles require different long life coolants- GM has Dex-cool, Ford just came out with another, Honda has their own. If the concentration is too great or too weak, it will not work correct.
How to flush radiator on 1996 blazer 4.3 l vortec v6?
Purchase a cooling system flush kit at auto parts comes with fittings adaptors and instructions
Where could an antifreeze leak be that would not be found by a pressurized test?
Your welcome.Off the top of my head, I would guess at a water pump from experience. Although, I would strongly recommend finding the real leak. Anyways here's a list of possibilities:water pump, head gasket, intake manifold, heater hose, radiator hose, bypass hose, radiator, heater core (usually leaks in passenger compartment floor), thermostat housing.As you sit in the driver's seat, where would you say that you see it? Center, right or left front of engine compartment? front middle or rear of engine compartment? How much and how often is leaking? Does it run rough? does it overheat?
Sorry I didn't re-read the initial question.Also add cap, reservior bottle and overflow to that list.One thought: A well known company can still hire a poor quality technician unintentionally and may have not pressure tested correctly or was not aggressive enough to find. There is a shortage of good technicians. if the system was low and pressure tested it may not have turned up. He should have pressure tested the cap to make sure it was good.Another thought: Assume the tech was good, Heat can affect a leak sometimes. I have seen it with waterpumps and head gasket leaks in particular. When it is cold the surfaces contract and seal a leak, when hot they expand and allow a leak-or vica versa.Another thought: Add dye to the system-make sure it is for coolant not oil. Any decent parts store should have this.
Dan,I would add the dye. Based on the location and other normal conditions present, it further leads toward the water pump.However, if it is in the corner right there is a possible seam leak on the radiator. I have seen both of these leak intermittantly.The Dye will help isolate it. Post what you find, thanks,Paul
Dan, I hate to beat a dead horse, but did you put dye in it yet?I had a 2000 Chevy Malibu that wouldn't leak until it was driven about 40 miles. If it wasn't for the dye, I don't know if I would have ever found it.If you can't find the dye, I'll find where you can.
Don't necessarily knock the other companies. It took me a painful 200 miles worth of test driving,6 cans of cleaner, at least 3 hours of labor of dissassembling and reassembling, 3 gallons of dexcool and countless shop rags to find this particular leak. Not to mention that it became a heated issue between the tech working on it and myself. He kept telling me it was a hose and I wasn't buying it. Oh yeah, we did this at no charge as well. She just put $600.00 into fixing the leak because we diagnosed it as a intake manifold leak. Granted she did have the manifold gasket leak and it did need repair, but I think the trouble one was the water pump. I also had deep sympathy for her as well since her daughter was brutally murdered less than a year ago.
If we had used the dye in the first place, we could have saved a lot of leg work, material and headaches.
Dealers have techs like any other shop. Just because they are the " Dealer", still only makes them as good as their techs, their policies, ethics and their perserverence.
Anyways, I am glad you got it resolved.
If you have a bad head gasket, cracked head, intake manifold leak, or even an exahust manifold leak you can have similar signs for all these problems. First question is does your car run hot or has it leaked or overheated recently? Even though you have a new head gasket I wouldn't rule that out. You are running your car around and since the coolant is hot it has expanded to fill the reservoir tank. When you park it at night the radiator will draw the coolant back from the coolant reservoir and empty it. On the weekend fill your reservoir and start your car and wait and watch as it is warming up. You are looking to see if the coolant is being forced out of the coolant recovery tank. This may not happen right away. If so that is a possible leak of one of the items listed above. It could also be the radiator cap so you could try that as it is probably less than $10 anyway. Get a new one with the same pressure as the old on or your car will run hotter (If less lbs). Do you have hard starting in the morning? (Possible that a cylinder has coolant in it). Pull spark plugs and see if any fluid is squirted out of cylinder. Also look at spark plugs. Are the plugs covered in a white ash or extremely wet looking? (Indicates same thing).Do you see white smoke from the exhaust with a coolant (sweet) smell? This could be intermittant. If so then you have one of the leaks listed above. You may or may not get coolant mixing with your oil depends on size and position of leak (Usually this happens when leak happens between cylinders). Look for coffee and cream color of oil. You would see this on dipstick or filler cap.Have a service guy do a block test to the coolant to see if exhaust gasses are present. (Should indicate a leak at any one of those points mentioned). They use a tube that is put in filler neck of radiator (It is filled with dye) if the dye changes color then you have exhaust gasses present.
I may not be a mechanic but I have been looking into this very problem, because I keep blowing the seams out of my new radiators.
What type of oil should i put in my peugeot 806 gearbox?
To keep a car running smoothly, the correct fluids must be maintained in the vehicle. 78W-80 mineral oil should be used in the Peugeot 806 Gearbox.
Where is the coolant temperature sensor on a 1997 Chevrolet Malibu?
It is in the intake manifold close to the thermostat housing.
No coolant, temperature rising a fact!! Are you certain you are loosing anti freeze? Simple fact, if you are loosing coolant you will experience overheating. You will have blown head gaskets or a complete engine failure. You must be catching it before it gets this far. The cause could be from a leaky hose connection, faulty cracked coolant hose, leaking heater core, leaking head or water gaskets, leaking water pump, hole in radiator. I may be over looking other causes, but I would check for leaks before it is too late. I have a mustang 5.0 that looses anti freeze very slowly. I can tell when it is getting low, before the warning light comes on, by the cooling fan coming on more frequently than normal. The leak is so slight I can not find it. If you are not sure you are loosing anti freeze and the temperature is rising, you may have a faulty temp. control on your cooling fan not letting it come on soon enough or at all. You do not need the cooling fan while moving or operating in cool climates.
What do you do if there is a brown foam in your radiator?
flush it dissconect both hoses and lfush it out good then refill with coolant flush it dissconect both hoses and lfush it out good then refill with coolant
When do you open bleeder valve for cooling system?
You should open the bleeder valve for the cooling system when the engine is cool and after refilling the coolant to remove any trapped air in the system. This helps ensure proper circulation and prevents overheating. Typically, you can open the valve until a steady stream of coolant flows out without bubbles, indicating that air has been purged. Always refer to the vehicle’s manual for specific instructions related to your model.
Why would the engine get so hot and engine lite comes on?
Engine overheating can be caused by any number of problems, large or small. The most obvious is a lack of water or antifreeze in your car. Without coolant, your car will (naturally) overheat. Usually if an engine is overheating it is accompanied by white smoke coming from under the hood by your cylinders, (below your spark plugs). White smoke is steam, and is usually burning antifreeze or water that has leaked into your cylinders and is being combusted along with the air and gasoline. One possible cause of this is a melted / old / worn head gasket. That was my problem :). You should let the car cool completely, so you do not burn yourself, then check the coolant level inside the engine. You MUST wait until the car's engine is cool, because the temperatures in an engine can reach over the boiling point of water, and if you open the cap to check the water levels, and the steam rushes out, you risk burning or blinding yourself. Other than that, i'd advise talking to a professional, or a engine-inclined friend for a more through inspection. Good luck!
Is engine coolant circulated through the transmission on a Aerostar 30L van?
There is a very strong possibility you have a blown headgasket and you have antifreeze intruding into your oil The reason you are seeing water in your oil is because water pressure will normally be greater than the oil pressure and water (antifreeze) will intrude and contaminate the oil
No, it is not supposed to do that. However, like most auto trannies, it does send fluid to the oil cooler in the left-side tank of the radiator, then back again. That explains the two metal pipes attached there. If the radiator goes really, really bad (i.e. the oil cooler corrodes out) you could get mixing, which would be a very bad thing. If this has happened, be sure to have a radiator shop check for electrolysis, and have a transmission shop drain, service and check out the tranny FAST.
You have an air bubble. The coolant level sensor is high in the block and you need to bleed the suystem of air in order to turn the light off. Not doing so will create hot spots in the engine block and eventual failure.
Does running the AC in winter do anything?
Yes. It is needed to dehumidify the air. Otherwise you can't clear the windows with the defroster very well.
