I got a 87 mustang GT that is bored .040 over. It is running warmer than its supposed to around 195 to 200 after about 30 minutes of cruising. Im wondering what i can do to make it cool better its got a big electric fan on it already. Im wondering if a 1 row all aluminum radiator will work to keep it cool like its supposed to be. I am also not running a t-stat. Or if anyone else knows of a way to get an engine to cool better im open to options.

here is deal. put the thermo back in. you have so much flow going through there that the coolant doesn't have a chance to cool down!! the thermo stat also slows down the flow so the air has a chance to cool down the system. i have a griffin 3-core aluminum. Works great for the most part. car sticks around 160 until i hit 10 lbs of boost... then it might jump up to 180 are you still using the AC?

no a/c or heater yea i heard of gutting the t-stat so all thats there is the ring i guess i could try that before i get the radiator.

Yeah i would say thermostat also, you may also want to find a radiator shop toclean and check your rad for build up or blockages. I have heard leaving the tstat out can break up some of the scaling and mineral deposits in the system and block the radiator.

EDIT: you still have your fan shroud on as well right?
