I have a 92 Es 300 and I am having problems with it overheating, I took it to the dealer and they told me it was not the head gasket or the head, and for 400 more dollars i could find out exactly what is wrong, but for that much i could do it my self. So i was wondering if anyone had any suggestions about what might it be. I keep pleanty of water in the system, and i have no hoses busted. I thought about having my radiator flused and maybe that might help , but i have no clue. Please help,

but my guess is the thermostat.

It's not sending information back to the computer to tell it to start the fan or do other things when the engine reaches a certain temperature.

I could be wrong, but worth look'in into.
Mahalo!!

 

I've seen many head gasket problems with that model. Without knowing what exactly the dealership checked, I don't know what to say.


Good Luck!
