It has always run a little on the warm side since i swapped it because i didnt get a dual core radiator. It started running a bit hotter so i replaced the thermostat, since i didnt when i got the motor, it still ran hot! So i got a dual core radiator and it ran great for about a week and a half. Then last night, out of the blue, it started getting hot at a stop light and continued to get hotter even when i started moving! I removed the thermostat and looped the fan switch to get it back home and it ran VERY cool the on the way home!?!? I hate cooling isues only because im not very good at diagnosing them so, ANY help would be appreciated!!
