I recently bough a 1990 IROC The car seems to heat up after 15 min of idling the radiator was flushed water pump changed thermostat also replaced the fans seem to go on at 230 degrees but its not enough time to cool down the car any ideas on why it could be doing this im 16 years old and dont know anything about mechanic RON GARCIA ONE OF THE CREATORS FROM MILE HIGH THIR GEN told me to come here because he doesn't do side work anymore

 

from what i understand these cars run in that heat range.

oh ok cool thanks but it also makes a weird noise it sounds like its coming from the fuel tank but the fuel pump has been replaced.

 

This is the typical operating temperature range. IIRC, the OEM fan switch for a dual-fan setup doesn't even turn on until 230°F.

I don't like those temps on mine because the engine smokes like a chimney over about 200°, so I wired a toggle switch to the second fan, lowered the first fan's on/off temps in the PROM, and have a 180° thermostat. Engine still runs fine and does go into closed loop on an otherwise stock tune, though I could probably get a bit better efficiency if I spent some time playing around with it.

 

well I got the radiator changed and I got a 160 thermostat and it seem to have helped im thinking of bypassing the fans so that they are always on.

 

That's a bad idea.
Here's a better idea: Jet Performance Fan Switch

 

Yeah fans always on is bad. The above suggestion is good. I put a 160 deg thermostat in my old bird and it helped tremendously. Never overheated. Heck it generally never ran above 190-200 after that. The only down side to that is the heat wasn't as great in the winter.
