i have a 94 1.8 with a 2860 turbo and and upgraded radiator (dont know which kind it was in when i bought it). it tends to run hot or overheats when im sittin in traffic or stopped at a light for a while and the temp gauge goes way up to where i have to sometimes shut the car off. i drilled a few holes in the thermostat and it didnt seem to help. do you think its because i have a fmic or because the underhood temps are too hot? both the fans work but it doesnt seem to help and i already searched for an answer but didnt find any good answers. the temp seems to go down when i rev my engine up though. i also have the splash guard under the car and the fmic isnt the big either.

You need to burp your system. You have the common symptoms of air bubbles being stuck in your engine. Lift the front of the engine as high as you can in the air. Then take off the radiator cap and idle the car. Let it run for a while and eventually air bubbles will come out. Once they have stopped put on the cap and the over heating should go away.

He said in the first post that both fans come on.
So now to the OP, do you have AC? Is it running when the car overheats? Or do how do you have both fans setup?
I still think there is air in the system. When you burped the system did the single fan come on and then eventually shut off?

no fans came on when i burped the system. im using 50/50 mix right now and i dont have ac either. when i put the cap back on and it idled for like 5 minutes after i was done the temp gauge moved up to like 3/4 of the way to hot. i burped the cooling system for probably like 20 minutes is that not long enough? i have both fans wiring to the same circuit for the computer to turn them on.
