the temp needle rises when the car is at a stop. Using a chipped P28 wiht obd 2-1 harness if that matters. The fan is hooked up and doesnt turn on... What could it be??

 

thermostat.

run your car for like 2 minutes...then check your radiator hoses (top and bottom one). top should be hot...bottom should be cool and you have a thermostat problem.

 

check thermostat and the plug to see if it has continuity

 

coolant not bled completely would be my first guess. you follow the helms to fill up your colant?

 

well it was a fresh rebuild. Ugh we started it up and just started putting coolant in , then water, once it warmed up the coolant that was sitting at the top of where the rad cap goes sucked down, so we added more.

- Fan is connected, and the fan swtich by the thermo is hooked up.

 

turn the heater on high take the radiator cap off and start the motor I bet you have a big air bubble in there. heater core will drain off a bit when you disconnect the lines. if the heater isnt turned on when youre refilling it it never fills back up.

 

im having the same prolem..with a chipped p30 ecu...cant figure this **** out...im gonna try to run the fan constant. see if that helps.

 

Thanks Monicle you solved my prob!!!

 

thermostat or possibly a clogged port
