If you are getting up to temperature in less than a minute, I would suspect a bad thermostat. Fan not working could be bad fan, bad fan relay, bad fan fuse, bad temp sensor, bad PCM.

Make absolutely sure you have enough coolant. Check in the radiator iteself. With the engine cold remove the radiator cap. Coolant should be up to the cap. If not, add coolant into the radiator.

If you live in a warm climate, just remove the thermostat.

As noted, the fan is a separate issue.

Got a 2001 bmw 316 e46 just put a new expanshon tank on an coolant and its over heating the fan doesn't come on and it boils the coolant and steam comes from under bonnet ?? Any idea where to start (

If your losing coolant water pump may be leaking, not enough coolant will make it overheat. If not that, thermostat may be bad stuck open or shut. Hope this helps

Where is the thermostat on 2002 toyota corolla

I could only find for a 1.8, shouldn't be much difference.

  • Mechanic's toolset, including a full socket set, wrenches and screwdrivers
  • Replacement thermostat, new or rebuilt
  • New gasket for thermostat
    • 1 Remove the cover on the right side of the under-engine. Drain the engine coolant into a sealable container.
    • 2 Take out the fan and the V-belt on the generator, then remove the generator assembly. Remove the two nuts that hold the water inlet in place and then pull the water inlet.
    • 3 Lift out the thermostat and remove the gasket. Clean the gasket mating surfaces thoroughly of dirt and old gasket material.
    • 4 Put a new gasket on the thermostat, then install the thermostat so that the jiggle valve is on top. Make sure the thermostat is set within 10 degrees to either side of the prescribed position.
    • 5 Connect the water inlet and set the two nuts in place. Tighten the nuts to 8 foot pounds.
    • 6 Set the generator assembly in place. Refill the engine with coolant. Start the engine and check for leaks. Replace the right side cover under the engine.
Tips & Warnings
  • Dogs and cats are attracted will drink coolant left in open containers or puddled on the floor and ingestion is often fatal. Drain coolant into a sealable container. Reuse the coolant unless it's contaminated or more than 4 or 5 years old.

thank you for choosing and welcome!have you replaced your thermostat lately? it may also only be low coolant in your radiator.just make sure that your radiators full of coolant. there are alot of things to look at when overheating is an issue. is your cooling fan coming on? #1thing low coolant,,,#2 thing leaking or bad water pump,do you see fluid leaking from under the front of car when the radiators full? #3 bad thermostat in the engine,replacement thermostat not that bad. less than $75.00 parts and labor,suggest you shop at local garages,not dealer. compare prices. or ban radiator fan. and the fan replacement can depend on motor size.look for motor size under the hood and call for parts and labor prices not call same garage to get labor and parts prices,be smart,call the dealer and get the highest price for part and labor. then call your mechanic to get estimates of your repair. thank you!

My 97 buick park avenue is leaking and causing the temp to go up where can i find the leak at?

It could be a number of places. I assume you mean that the coolant is leaking. You need to get it pressure tested to find the leak if it is not "dripping" where you can see it.

97 Honda Accord running hot. The water seems to be boiling into the plastic bottle. The water disappears in the radiator after a couple days. I am thinking thermostat.

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.


Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.




You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!


Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost


A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

Please post more information by clicking the comment link on the top right corner.

Running Hot

You may want to reconsider if the fan is working at it's full potential.It seems when the vehicle is moving the extra air flow compensates for the fan not blowing hard enough.Check for radiator obstructions such as leaves and debris.And check for small leaks.Also there may be an air pocket in the system which can still seem like the system is full.With vehicle cold take off radiator cap and run vehicle.Turn on heat to highest setting (blowing).When vehicle reaches thermostat rated temperature(opened thermostat) you will see coolant go down in radiator.Fill radiator while the engine rpm's are up (have someone hold the throttle to where the rpm's are at about 1800) then put on cap before returning to idle.This should remove the pocket if there is one

Where is the thermostat in a 900s oh. 97 saab 900S Well my car was overheating and I notice in this model car if you need your oil changed it will overheat. So there is oil and all my fluids are full...

Oil change interval has nothing to do with operating temperature. If your coolant is full, feel the upper radiator hose, when the vehicle is up to temp. if cool , thermostat is back from that hose,

Look for air bleeds, and read owners manual, some cars have coolant bleeds. Also, heater on high when filling coolant or risk bubbles...

My thought is that your fans may not be kicking in. They should cycle on and keep temp low enough. test them.
