I"m having over heating problems with my FC, and just replaced the thermostat, there are no coolant leaks, any suggestions would be helpful to solve this problem.
any ideas could help alot.

 

What brand thermostat? overheating before the t'stat replacement or just after? or both?
RX7's dont seem to like the stant t'stats for some reason.

 

i purchased a thermostat from mazda dealership which they ordered, the over heating problem has been happening before i replaced it. any other ideas on why my car continues to overheat?

 

When does it overheat? Idling? Cruising on the freeway? It could be blockage in the radiator, problem with the fan clutch. More info on your car and relevant mods too.

 

Yeah if it is overheating on the highway, do you have your underbody tray installed? If it is overheating when stopped in traffic thats probably your clutch fan, or your not running a fan shroud. How long have you had the car have you had the radiator flushed? Are you running an efan. Need alot more info.

 

Sorry to bump an old thread, but I'm having a heating problem. I live in Florida and my microteach ecu says ill be doing 100c on the freeway with "spirited" driving if you know what that means. I have a turbo swapped GXL with the TMIC, I've had to move the temp sender to where the thermo-switch used to be because the NA temp sender is smaller than the turbo II sender and it does not read properly with the T2 sender. I think it has something to do with the different resistances (its been replaced twice and its doing the same thing).
I have yet to replace my thermostat so I'm wondering if that is my issue.
