SOURCE: 2003 corolla heater temperature varies

check your in cabin air filter located behing the glove compartment. see your owner's manual for directions.
When this filter gets clogged air flow is restricted. You can blow the filter out with compressed air or replace. make sure you put in right side up.

Ford Freestar 2006 Engine is temperature is normal but , the dashboard gauge is showing high temperature. Which parts need to be replaced to bring back the dashboard gauge to normal.


How do you think the engine temperature is normal if the gauge is telling you the engine is overheated?

make sure the engine is filled with coolant both at the reservoir and at the filler cap on the engine itself. Usually this cap has the thermostat below it. If they are full, try burping the system by squeezing the radiator hoses with a sealed system and the engine hot. Wear gloves!

if that doesn't fix it, buy a new thermostat. They are cheap and easy to install.

If if that doesn't fix it then you are looking at emptying the coolant system and back flushing it after adding something like CLR or Radiator Flush.

Might also be a fault with the pump or a slipping belt?

Your coil that allows air to pass through for A/C or heat could be plugged or the thermostat is sticking.

Replacing a thermostat


Buick Park Avenue Thermostat Repair Recommendations Best Practices
  • The entire cooling system should be inspected and tested when the thermostat is replaced.
  • A high-quality OEM thermostat should be used. Poor quality thermostats may not function properly and can cause damage to the engine or components of the emission system.
Common Symptoms
  • A thermostat that is stuck closed will cause the vehicle to overheat.
  • If the new thermostat does not immediately resolve engine temperature problems, the cooling system needs to be checked for other issues.
  • A thermostat that is stuck open can cause the engine to run colder than normal and set the Check Engine Light. It may also cause poor fuel mileage and the heater to blow cool air.
The thermostat will be at the end of one of your radiator hoses that goes into the engine block; normally at the top of the engine.

My heater does not blow hot air. 1 thermstat has been replaced 2 could water pump be bad 3 water does not seem to be circulating through the hoses. 4 the air mixer under the dash seems to be workig.


If the thermostat was recently replaced, it could be trapped air in the cooling system. First, you need to establish that the thermostat is working. Remove the radiator cap and start the engine. Let it warm up to normal operating temperature on the temp guage. Make sure the heater is set to the hottest setting. Observe the coolant in the radiator. If the coolant is flowing when the engine is cold, then the thermostat is stuck open and the heater won't get warm. If the coolant is not flowing, continue to watch the coolant. When the thermostat opens, the coolant level will drop in the radiator tank, add antifreeze to bring it back to full. Each time the coolant level drops, add more antifreeze. should the thermostat close while doing this, antifreeze may spill over from the radiator tank. No to worry. As son as the thermostat opens up again, add antifreeze to fill the tank. Continue to do this until the coolant level no longer drops. Sometimes it is necessary to raise the front of the vehicle so the radiator is high than the engine in order for the air to escape. Put the radiator cap back on. If the problem was air in the system, then the heater should be warm now. In the old days we would just drill two 1/8 inch holes in the new thermostat before installing it. That allowed the trapped air to escape slowly. Might still be an option.Let me know if this helps.

Hi..my question to you is why would a 1997 subaru outback legacy overheat if the fans are working?


This can be a leaking cylinder head gasket (common on this Boxer engine).

Temperature gauge goes to hot and shortly later goes back to normal though car does not seem to run badly even while needle is at hot . reserve tank seems to draw antifreeze


you need a new thermostat, its sticking and causing you problems, soon it will just stay stuck, the reason the reserve keeps filling up is because of heat and pressure in the radiator

Hi Code P 0217 does point to the thermostat but it also points to the wiring, cooling system, and the temperature sensor, to check the thermostat start engine then once the temperature gauge in the car reaches normal the thermostat should open and the top hose that goes into the radiator will warm up quickly as the thermostat opens, if the thermostat is stuck in it's open position the top hose will start warming up before the engine reaches it's working temperature, hopefully i have explained it clearly,

Your thermostat is probably stuck open, not allowing the engine to warm up to its normal operating temperature. The coolant circulates all the time, so the radiator is constantly dumping all of that heat. Replace the thermostat, and your problem should get better. You may even consider installing a higher temperature thermostat if you live in a colder climate.

it sounds like a possible head gasket problem,you can get the fluctuation from combustion gases getting pumped into your cooling system and creating gas pockets,i would suggest taking it to a shop and have them do a block test to look for combustion in the cooling system to confirm the problem,that way you will know for sure,if it comes up negative they can also perform a flow test to make sure there is no restriction in the cooling system such as a plugged radiator or a bad thermostat,hope this sheds a little light on it

Overheating


Hi,

Pls check the thermostat. It is most likely a sticking or even stucked as that is basically its purpose, to restrict the coolant flow and allow the engine to reach operating temperature thereafter grant free flow of the coolant. It would seem that there is considerable delay in its opening and therefore the temperature rises above the normal operating temperature.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
