Hey guys, I just replaced my stock Radiator with a Griffin Aluminum one and the engine is running hotter than the stock one... The thermostat was working great before, so I don't think thats the problem... Any help would be great... Thanks...

Make sure there are no air bubbles left in the system.This drasically reduces the efficiency of the coolant.A bottle of Redline Water wetter helps with overheating problems.

 

Make sure you burp the system. Like Chopper said, you have to get all the air out.
