Ok, I have done some searching and havent turned out any results. I just replaced the thermostat 3 days ago. My car is running hot all the time. I have a 99 EM1 and it has the stock B16A2 with a few small mods. Just Intake, and exhaust, and a lightweight flywheel. The problem occurs everytime I drive. I stop at a red light and the temp starts climbing. My relay is out on my fan so I wired up a switch to it so i can flip the fan on when the temp climbs. Well, now the fan is doing no god and at every red light, my car is running very hot. One more thing...my reservoir for coolant is busted. Whenever the radiator gets too hot and overflows i lose that coolant. I know that is bad and i keep it filled up, but should it really be that hot? So basically my question is: What else could be causing this overheating? and Should my radiator overflow everytime I drive? thanks

 

bad coolant temp sensor? or maybe bad water pump?

 

I thought about the sensor, but wouldnt thet throw a CEL? I didnt think about the water pump. Im gonna look into thet. Should it be geting hot enough to overflow into the reservoir?

 

bump...

well, for starters fix the relay for the fan. also, replace your resevoir, you are allowing air into the system which is probably causing the overheating problem.

by the way, did you bleed the coolant system when you added the new thermo?

Wow, i sure didnt think about it letting air back into the system. Cant believe i didnt think about that. Thanks for the suggestion and ive definately got to get a new reservoir. Im gonna fix the relay soon. I bled the system when the thermostat was changed. thanks for the reply.
