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.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

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.

SOURCE: Poer steering fluid is leaking. Fan runs slow

Check power steering rack. on the camarys its alittle more common than most cars. poke a hole in the boot and watch for a leak. Nothggn should come out of there. If you have fluid coming from the boots then your internal seals are leaking on the rack. a small hole will not hurt the rack if nothing comes out.

Also check your power steering pump shaft. sometimes the seal will leak
.
I think your over heating problem may be a different problem all together.

Hopefull that helps.

SOURCE: overheating from leak not visible

Hook up a cooling system pressure tester. If you have a pin point leak, the pressure from the tester will shoot coolant out of the leaking area.

SOURCE: I recently replaced my water pump. this afternoon

Check your thermostat. It may be sticking and keeping the coolant from flowing, hence the overheating. Where above the water pump is it leaking? Hopefully you didn't blow a head gasket.

I think my trans fluid is leaking into my antifreeze somehow? Could it be the radiator? Does this radiator have trans lines running through it? For cooling? No water in trans! But low on fluid! Car has...


meqst2010, This could be a radiator problem. Look at the side reservoir of the radiator and see if there are lines coming in. This is for the cooling of the transmission fluid and the internal cooler may have sprung a leak. When the vehicle is cold open the radiator cap and see if the fluid if floating on the top. If so then you will have to have the radiator replaced and the whole cooling system should be flushed. I would have the transmission fluid and filter replaced as well as a precaution. Good luck with this.

Car overheating & transmission is slipping


Sounds like a bad radiator. The radiator doesn't just cool the coolant. It also cools the tranny fluid. So if it just started overheating and slipping at the same time then the radiator has probably leaked out enough coolant to make it overheat and enough tranny fluid to make it slip. Check for leaks or wet spots where you park. And obviously check both fluid levels.

Car overheated and blew radiator fluid


you need to rent a coolant system pressure test tool from autozone, o'reily's, or any parts store. cost is $20, you get your money back when you return tool. very easy to use, fill radiator and resorvoir with water because coolant will only be wasted til you repair leak. attach tool to radiator and pressure up to somewhere around 12-15 psi. dont exceed 15 psi. pressure coolant system and look at water pump, radiator and hoses, heater hoses, scan engine.any and all leaks will be revealed.

My 1997 ford explorer overheated and the transmission slipped


Tranny fluid may have been contaminated with coolant since tranny cooler lines go to radiator or condensor.
I would fix your leak on radiator, then completely drain tranny fluid and filter and replace.
