    I would look into getting the cooling system pressure tested. Could be a head gasket. Are you losing coolant? Any unusual coolant issues?

It is possible you have a defective water pump. This happens all too often. I would first suggest checking the serpentine belt for the correct tension and for defects such as glazing or debris in the groves of the belt. This is called 'pilling' and can cause the belt to slap around the pulleys failing to make correct operational friction with one or more component pulleys and/or tension adjusters. At different rpms you may see the issue come and go. Also check the pressure relief cap and hose on the overflow / fill reservoir tank. DO NOT EVER ADD RADIATOR STOP LEAK OR ANY TYPE OF HEAD GASKET OR BLOCK SEALER. THESE PRODUCTS STAY IN YOUR ENGINE AND SHORTEN ITS LIFE.

Was the thermostat placed in the thermostat housing correctly? The spring end goes inside the housing toward the engine. Has the cooling system ever been back flushed? Take a flashlight and look inside the radiator (make sure radiator/engine is cold!) you may need to remove a little of the coolant, and look to see if the fins appear to be full of a white deposit. Possibility the radiator may be clogged .

If you fill the car with anti freeze when it is cold and start it up with the cap off and its bubbling in the radiator that fast it has a bad head gasket.You can buy a kit at the parts store to confirm this.It made to detect hydro carbins in the coolant.Let me know what you find out Thanks...Dan

Check your oil dipstick for coolant, or a mucky substance. Your symptoms sound like a blown head gasket.

Hello Justin.
If your thermostat has been replaced with the proper one your engine is heating up.
The problem then becomes twofold.
The amount of coolant/antifreeze flowing through the heater core or a problem with the airflow over the core inside the heater plenum assembly.
I would check for coolant flow through the core first.
If the heat feels like it is warmer coming out an outlet with the fan on a low setting rather than a high one your heater core isn't flowing enough.
To verify you can also check the two hoses that go through the firewall to your heater core once the vehicle has been warmed up, feel the temperature difference between the two. They should both be almost hot enough not to hang on to and close to equal temperature. A hand held temperature gun is really handy for doing this.
If one is hotter than the other your heater core has restricted flow and will need to be flushed or replaced.
Next is to check your temperature blend door operation.
Move the control to hot and cool and listen for the door to move and feel for the temperature to change, if it does at all. The fan on low setting is best to listen and feel temperature changes.
If you feel a temperature change or hear the door thump at each end of it's travel it is OK.
If you have more questions on this problem leave it in "add a comment" and I will return your question.

SOURCE: HEAT BLOWS COLD AIR WHEN IDLING ONLY GETS HOT WHEN START DRIVING

You have still got air in the system.Remove the Feed back pipe from the header tank and wait for all the air to come out while the engine is running making sure you are toping up the header tank at the same time Dont allow header tank to run dry while doing this.Good luck

I have a 2002 civic 1.4s and its starting to over heat only on a stop start mostly no grey smoke


Hey Steve,
Does it overheat when you drive at highway speed? If not, and only overheats during stop and go driving, then you might have:
1. A water pump going bad.
2. A thermostat that is going bad,
3. The radiator hoses are getting soft,,(Need replacing)
I would start by removing the thermostat and driving for a while and see if it clears up.. (this DOES NOT eliminate the water pump though, because its easier to pump coolant without a restriction), but this will help you with your diagnosis, If it stops overheating without the thermostat,, ok, now replace the thermostat (with a new one!) and drive again.. IF it starts over heating again, you need a water pump. ,,ALSO..while hot.. check the hoses for evidence of collapsing..replace if necessary..(they wear out from the inside.. there will be NO signs of wear from the outside! (I replace mine every 6 years NO MATTER!!!)

Hi guys I am new on this, I will start all over, I got this big problem for me, I got this 2002 huyndai elantra gt, 1 week ago I was driving and the heat stopped working, no radiator leak, everything...


Ok, here is my take on your problem. As you may already know, it takes a car a few min. to actually warm up to operating temp. When the coolent reaches operating temp. the thermostat opens to circulate the coolent in the radiator. Now, as your drive, the air pushing against your car will actually blow some air through your heating system ducts and into the passenger compartment. Is it possible that your blower fan isn't working? Because while you are stopped, there would be no air forcing its way through your ducts, thus no heat. As your drive, your car gets up to operating temp, heats up, and the air pressure as your drive will blow some heat out into the passenger compartment? On a side note, if your thermostat is stuck in the open position, it would take it forever to warm up since it is circulating ALL the coolent even tho it isn't at operating temp. A thermostat stuck open will take 30 min or more before you actually feel any warmth, if at all in the winter.. your thermostat opens and closes constantly as the engine is running to keep it at its normal temp, usually around 160-180 degrees. If you live where it gets really cold, a thermostat stuck open likely will never get warm. If your blower motor works, and your engine don't overheat, im 98% sure its your thermostat.

Audi A6 2001 quattro 2.8 mysterious over heating


Yes, replace the thermostat. Then you need to 'burp the coolant system'. Your car has all the hallmarks of air in the system, especially a heater that is cold. This is because there is no water in the heater matrix. This is why it overheats. The system must be full and with no air to circulate correctly through the radiator.

Burping involves the following steps.

Remove the lid to the reservoir, remove the radiator cap, fill the radiator to the top, turn heating on full blast, start engine and get to operating temperature, keep topping up. Squeezing the radiator hoses helps. The level will rise and then drop when the thermostat opens. Top up when bubbles stop and the level becomes constant. Put radiator cap on, top up the reservoir and put the cap on that.

Engine over heats


Check for collapsed radiator hose first.

Do the cooling fans come on? If not, check fuse, relay and if still no function- fan thermostat switch.

If fans do come on, replace water pump.

I have a bmw 328i 1996 and it overheats but my oil light comes on and soon after the car starts to try and cut of i changed spark plugs and new oil change........ wats wrong with my baby


Most likely a bad Thermostat or Water Pump. Replace the Thermostat, the cheapest part, and if it still overheats replace the water pump.

I have a 1997 kia overheating i have removed the thermostat


You have to install a new Thermostat because if the motor has no water pump thermostat sends all the coolant to the radiator and therefore the engine never warmed and you will not have heat because the coolant never be heated

Car is overheating, thermostat was changed and the radiator was flushed, car does not overheat while idoling, but when you start driving it overheats


It sounds like water pump may be your problem. It circulates a 50/50 mixture of glycol (or some form of) and water through the engine block and cylinder head and back through the radiator. In the radiator the mixture is cooled when air passes over the fins of the radiator. This is accomplished by driving or a mechanical/electrical fan when stationary. The water pump also circulates the mixture through the heater core giving the car heat. If the water pump is not circulating the water back to the radiator to cool, it will overheat. More heat is caused by the engine when driving (much less heat when idling), hence the overheating while driving.
I hope this helps and good luck!

Classic signs of a bad water pump. When on the freeway, the circulation of coolant through the system is increased due to the speed but once you slow down, it will tend to overheat. Please post back with any other questions or just to rate the solution. Thanks very much!
