Question about 2003 Honda Civic
I got my radiator fan replaced it was still running hot took it back in they said the cooling fan switch needs to be replaced is the cooling switch supposed to be replaced with the radiator
It is not necessary to replace the thermo-switch when replacing the radiator. The switch can be replaced separately.
The fan switch is located under the sound box of the air cleaner. It is 2 pin connector. Pull the connector out by pressing the lock which attached to it and short the two pins with a thin auto wire temporarily. Switch on the ignition. The fan will become on. Drive it and see if runs hot.
If the temp reads OK, replace the fan switch. If the problem persists, diagnose the other issues which are concerned with the overheating problems.

hi i don't know what mechanic you went to but blown head gasket will cause the engine not to idle/run right. usually when you replace the thermostate you have to then run the car obviously with water in the radiator and crack the little screw where the thermostate is located. this will allow the car to release any trapped air in the lines and you may need to keep topping up the radiator. im not a mechanic but i know alot about cars. i came across this problem in my holden ute. it was running hot and that was why. too much trapped air. easiest way is too crack that screw and remove it. run the car while keeping an eye on the radiator water level you will see if there is air in there it won't squirt water out continuously once it does run continously turn the car off put the screw back in warning it will be quite hot retop te radiatior if need and you should be good too go. it solved the same problem i had. have fun cheers

You should have a check engine light on if your coolant temperature sensor is bad. It could be your fan relay. It's position should be located on your fuse box cover(s). To check the fan itself, unplug it and notice that the black (or darkest) wire is the ground, so you can hook your jumper wire to any metal part of the car. The other wire goes to the positive terminal of a car battery. Good luck.

I would have it checked for a blown head gasket. Combustion gasses in the cooling system can keep the temperature switch for the fan from operating properly.
