Question about 2002 Toyota Camry
My vehicles temperature gauge will max out if driving slow or idling, My air conditioner will lose its cooling compacity also. When I get into open air and speed up it scools down and air conditioner works fine. Already washed the radiator off several times thinking it was dirt buildup.
Indicates that the fan is not drawing air through the radiator at idle or low road speeds
If viscous fan hub --replace it
if electric fans check
coolant temp sensor
2 fuses , relay . fans . ECM

The Normal Temperature Range to the Fan Start is: A/C ON 181 F.
A/C OFF 199 F. When the Engine Reach this Temperature the Fan should start.
OK. Do this simple test.
1---- Start the engine, Desconnect the ECT Switch located on the Radiator,
See if the Fan come ON. If yes, if not go to step #2
Connect the ECT SWITCH and leave the car Running and with a Temperature gage.
See the temperature, if the Temperature go more than 199 F.
Turn the Engine OFF.
Disconnect the ECT sensor and check for Ground at the WHITE/BLACK wire.
If ground exist, Replace the ECT switch.
But if not. Check the wire for any damaged, and the ground at the Front Left Fender.
Repair as need.
2---- check the Fuse link RDI FAN . 30 amp.
Check the Fuse link CDS FAN 30 amp.
Replace if need.
And Return to step # 1.
Check the Radiator fan Relay, Rad fan relay 2 and 3. Replace if need.
Ok. I hope this help on your question.
I can give to you the WIRING DIAGRAM of the Fans, But I need a E-MAIL adress to do that.
Thank you for use fixya....

original issue sounded like thermostat but now that you have lost power i would have to say thermostat, blown head gasket, and warped head
to check thermostat find and remove place in pot of boiling water the see if it opens, then to ice water to check if closes.
the only way i know to check headgasket and head is to check oil and water. oil will have water in it, and water iw have oil in it

Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).
Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.
Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.
Fourth, make sure the radiator (and associated hoses) aren't blocked.
If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.
However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.
If all above components test ok, then it's possible your water pump may not be pumping enough volume.

Testimonial: "I appreciate your help...Maybe I should just relace the water pump, that would be the last thing that I would need to replace."
