My car overheats and I've replaced water pump, thermostat, coolant temperature switch, radiator three different, relays, fuses, bled the cooling system. The fans turn on at 230 degrees. I've taken it to three different mechanics still could not
fix it. They say the head gasket is good. So now I don't know what to do.
Do you
have the same problem?

Hello,

Did you physically check the opening temperature of your vehicle's thermostat by placing it in a pan of boiling water to verify that it is opening when it should? I have seen and bought thermostats that were bad right out of the box, and it is very frustrating because that part is good, it's brand new, in your mind and you wind up chasing your tail because of it. I would suggest doing that first, keep it basic, there's not a lot to an engine cooling system. I have included the specs for your vehicle's cooling system in the diagrams down below.

Thanks,
Alex
