What might be the problem in a 96 Nissan Altima if coolant is leaking from the rear of the engine and the pressure test came back showing no problems?
your head might be going out
Can be a hole in the radiator or a problem with one or more of the hoses. A mechanic can run a pressure test to see where the problem(s) are located at. Read More
You need to pressure check the coolant system to determine just what is leaking first and the address that problem.......... Read More
Have system pressure tested at local shop unless the problem is obvious. Check coolant lines (upper and lower) to see if they are leaking. Check radiator for leaks. Water pump may be leaking. Also head gasket could be letting coolant in to oil. Pressure testing will check all these components Read More
You have a leak in the cooling system. If you don't see evidence of coolant leaking on the ground, you probably have a head gasket problem. Have the system pressure tested soon before more serious damage is done. Read More
What is happening when the coolant reservoir is overpressurized and starts leaking from the cap Is this a thermostat problem or cooling fan switch problem?
Is it too full? Well some vehicles are equiped with a little hose that will let coolant out if there is too much or too much pressure, but not all vehicles will have it. (If you are talking about the overflow tank, if the radiator cap is leaking, check to see if the cap is in good condition) Read More
If only adding coolant to a leaking system it is safe because soon you will be forced to drain the coolant and fix a problem Read More
What could the problem be on a 97 dodge ram if antifreeze still leaks badly even after the thermostat has been replaced and the radiator and pump was pressurized by a professinal and found no leaks?
Where is it leaking? That pressure test sounds funny, why would you pressurize only the pump and radiator? If you are leaking coolant outside the engine, locate the source. If you are losing it from the radiator but cannot find a puddle suspect a head gasket problem. Check the Radiator cap first, if it is bad high pressure coolant will travel back to the overflow bottle. Read More
If coolant isn't leaking externally then it has to be leaking internally. A leaking head gasket or cracked head may be the problem. If this is the case, as it gets worse more coolant will enter the combustion chamber or engine oil. Either way you will be able to determine as it gets worse. There will be white smoke from the exhaust. May be intermittent. This is if coolant is leaking into combustion chamber. If… Read More
If it is an automatic transmission, the cooler in the radiator is most likely leaking into the coolant system. Read More
What do you think could be the problem if your car is leaking radiator fluid but the heat still works?
Eventually heater will stop working when coolant level gets low enough. Pressure test system to determine where leak originates Read More
Leaking or loosing coolant? If it is leaking then where is the leak? If it is just loosing coolant with no apparent leak, then you more than likely have a blown head gasket or cracked head. If there is coolant in the oil, or white sweet smelling smoke coming from the exhaust you definitely have an internal problem. Serious engine damage will occur if you continue to drive this vehicle. Read More
Losing a lot of coolant can be a serious problem if you don;t keep an eye on the coolant level. Low or no coolant will cause the engine to overheat and cause some serious damage. If the vehicle is not blowing white smoke (steam) out through the exhaust (a sign of blown head gasket or cracked cylinder head); if the radiator or radiator hose(s) are not leaking; if the water pump is not weeping (a… Read More
It can run but if it is leaking coolant it will cause a problem soon. Read More
Just because there is a leak doesn't mean it will overheat instantly, but if you do not keep adding coolant or fix the leak you will have engine problem Read More
A blown head gasket can allow coolant to see into the manifold, and out the exhaust. A broken piston ring can also cause this problem. Read More
It will be safe to drive short distance as long as the car does not over heat. You can top up the engine coolant or use water/coolant mixture till you fix the problem which could be leaking hose pipe. leaking radiator or faulty radiator cap Read More
What would be the problem if you replaced the water pump and thermostat 3 times you have enough coolant but it looks like it is leaking anti-freeze?
What other symptoms besides leaking antifreeze? Where do you see the anti-freeze leaking? Read More
Engine coolant is leaking from the rear of motor on my gmc Z71 pickup truck. what are the possible causes of this problem?
If coolant is leaking from the back of the engine it is most likely that the intake gaskets need replacement or a possible heater hose connection depending on the year. Read More
If pressure builds up in the cooling system as soon as you start the engine, you have a problem. If you're leaking coolant from the oil into the crankcase, you have a problem. If you're leaking oil into the cooling system, you have a problem. If you have low compression on two adjacent cylinders, you have a problem. Unfortunately, you can't know WHAT the problem is until you remove the head. All of the above… Read More
My car's engine shakes oil is in the coolant The engine runs hotter then usual and at one time I was leaking coolant Do I have a Head Gasket problem?
I would say yes, if oil has mixed with the coolant, that's the most probable cause. Read More
it is normal, when the coolant is hot and pressure built, the pressure cap allows the coolant to drain to reservoir to reduce pressure in the cooling system But, if it continually does this whereby the reservoir overflows and the vehicle overheats due to a lack of coolant actually in the radiator when cool, there may be an overheating problem or blown head gasket on the engine. Read More
Bad head gaskets leaking coolant into comustion chambers, reason for no visible leaks. common problem on diesel engines all over the world. Read More
1. Water pump possibly weak, failing or leaking coolant 2. Thermostat is not operating correctly or the housing for it is leaking coolant. 3. The water jacket in the engine block has possible restrictions or leaks somewhere. Head gasket breach...leaking coolant? Freeze plugs on side of block? 4. The radiator hoses (upper or lower) have issues and are leaking. What area of the engine compartment is the STEAMING COOLANT coming from? Top, Bottom, Front, Back… Read More
if its a 3.1v6,then it is a intake manifold gasket problem, the 3.1 a noted for this!! check to see if gasket is bad. Read More
Bad hose or clamp where the heater core is connected would be the most likely problem. Read More
A faulty thermostat in a 2001 BMW 325CI can cause a coolant leak. The coolant may be leaking out a crack in the thermostat or through a warped edge. In some cases the problem may be just a bad gasket and not actually a problem with the thermostat at all. Read More
I had this problem and the manfold gasket was leaking I am aware of sensor issues with this but I has to replace the manifold gasket problem solved. Read More
On a 1995 grand am 3.1 you did an intake gasket now it is leaking coolant from the over flow Also it seems to be leaking where the gasket went on any suggestions?
By chance, did you use sealant when you put the new gasket on? If not, there is your problem. Read More
95 Corsica coolant light comes on I have filled the reserve and then let the car run for about 5 minutes but the light still does not go off can i still drive it with out worrying?
First make sure the Cap on the coolant tank is screwed down snug and not loose, lose of pressure from a loose cap in the coolant system can trigger your light to stay on. If this is not the case then Drive your car as LITTLE as possible until you can get it into a repair shop! Just because your coolant tank is full doesn't mean that a problem isn't still lingering. I had a… Read More
Pentosin G12 coolant is pink. If it's leaking inside the car, that sounds like a heater core problem. If it's leaking on the ground, the passenger side is where the hoses and water pump are. Read More
Coolant has to be refilled once a week and is not leaking from radiator or hoses and is not getting into oil where is it going?
Answer Check under the input shaft of the water pump. If there is a colored streak, it's probably leaking there. Leaking head gasket could allow coolant to pass out the exhaust. There would be a sweet smell at the tail pipe. Had a problem like this once. Have the radiator pressure tested and look for leaks. Could be coming from the weep hole as stated above. Generally if antifreeze is in the exhaust the tail… Read More
Depends on where its leaking from. Could be a clamp hasn't been tightened enough. If its coming from elsewhere, it could be a leaking head gasket. Look for coolant in the oil or coming out the tail pipe. Read More
I keep losing antifreeze no leaks to be found oil looks good and no sign of it leaking on the floor what next 2000 impala?
If it is not leaking externally then it is leaking internally. The intake manifold gaskets are known to leak coolant into the engine on that vehicle. Have a trusted mechanic diagnose the problem soon because coolant mixing with engine (even in small amounts) oil will cause big trouble down the road. Read More
That is a common problem with the vortec 350 engines. The intake manifold gasket starts leaking in the corners of it. That is where the water jackets are and it's only about 1/4 of an inch wide and when it starts leaking it allows engine coolant to leak into the lifter gallery and into the oil. Need to replace intake gasket as long as you no it did not freeze and crack the engine block. Read More
One of the problems with the 1989 Yamaha VMax is the sparking from the spark plug. Another problem is the leaking under the dashboard. Read More
My 98 Ford Taurus is not over heating but there is oil in the radiator overflow. However there is no water in the oil. What is the problem?
There are two possibilities, one it is most likely the automatic transmission cooler( in the radiator) is leaking transmission fluid. The other, engine is oil entering the cooling system through a leaking headgasket, cracked cylinderhead or engine block.Keep in mind that the engine oil pressure( normally) is allways higher than that of the coolant system , when engine is running.It is rare but possible that engine oil @ say 40 p.s.i. is entering the coolant… Read More
Without seeing or pressure testing the system my most educated guess would be that the intake manifold is leaking. Read More
How can you see where the coolant leak is coming from It seems to me that its coming from between transmission and motor?
It is possible for coolant to leak out between the motor and transmission, if a freeze plug has been leaking. I had this problem on an old International Travelall I had. The motor will need to be pulled. Read More
Not really enough information given about the problem. BUT, here are several possibilities: leaking coolant hose - the water pump is failing - the radiator may be cracked. ALSO, if it disappears but leaves no puddle under the car -- the head gasket may have failed and is allowing the coolant to leak into a cylinder or into the crankcase. Good luck. Read More
have the coolant system pressure tested to help diagnose your problem. Read More
S10 coolant inside car I have a 1989 Chevrolet S-10 pick up 4.3 V6. I Discovered a lot of coolant inside the car on the passanger sise What is the problem?

The heat stopped working on your 1993 Toyota Camry The radiator is not leaking the thermostat is good what else could cause this and how do I diagnose problem?
Cooling system airbound? Temperature control not working? Low coolant? Water pump not circulating coolant? Read More
Lots of possibilities. Here's what I can think up in a few minutes. Is the liquid visibly leaking out or just disappearing? Does it come out in bunches or in drips that show up on your garage floor? The radiator could leak through a seam, or due to corrosion in the main core. The heater core could be leaking. Leaking hoses. This could be the main radiator hoses, or the two that go to the… Read More
My car's engine shakes and oil is on the coolant and the engine runs hotter then usual and at one time I was leaking coolant so Do I have a Head Gasket problem?
id say you do have a head gasket problem or if not the head could be cracked or warped. id recommend a radiator pressure test for leaks, and a compression test for the head. remove all spark plugs before beginning tests and take two readings from each cylindar. take the highest reading. cheers Read More
How do you check for internal leaking on a 99 Malibu in regards to overheating i have a v-6 3.1 motor i have changed almost everything under the hood could it possibly be the cap on the overflow?
When a engine consumes coolant and there is no visible leakage on the ground, this can be caused by a leaking head gasket or intake gasket which allows coolant to enter the combustion chamber where it is heated and turned into steam. A pressure cap will generally not cause this type of problem. I would suggest you bring your car to a reputable garage and have them do a leak-down test to the cooling system… Read More
It would probley have an engine mis, may even be smoking white are blue out of the exhaust pipe, May be weak on power. Take the radiator cap off when engine is cold fill it up with coolant, leave cap off and start engine. If it bubbles water are air bubbles out of the radiator while it is running are blows water out then you have a cracked head are blown head gasket. There are… Read More
You have antifreeze leaking only when car is running It is dripping down underneath the passenger side next to trasmission It is pure coolant You changed thermostat?
I would check the hoses leading into your radiator, and also the overflow for antifreeze. If that is not the problem, it could be your heater core. Your heater core might be leaking, you might have a hose leaking Read More
It can be battery, faulty coolant temperature sensor, faulty cold start injector, malfunctioning fuel system, injector leaking. Read More
Sounds like a bad head gasket or cracked head problem but we really need to know the year, make, model and engine to help you. Read More
Yes it can but the thing you have to look at is the oil pressure is higher the the coolant pressure. Your oil is about 30 to 60 psi, where as your coolant is about 16 psi, at running temp. I would look around the intake manifold in the corners of the heads to see if any coolant is leaking out or showing signs of wetting. Now the coolant can enter if the engine is… Read More
