I've been told that I need to replace my coolant temperature switch, so I bought one. My problem is that I can't find its location. parts store couldn't tell anything.
My problem is that's leaking water, I think it's coming from the radiator plug. engine coolant fan not working. acc fan works only. I bought a fan for it. but if the switch isn't good,, it still wont come on.

Hello!

I've attached the component locations for the engine coolant temperature sensors and a schematic for the cooling fans and ECT sensors (below).

Additionally, you may find these tutorials helpful:

This video describes what is involved in performing a cooling system pressure test to check for coolant leaks:

Please let us know what you find and if there's anything else we can help with.

Thanks, Wendy W
