So this questions mostly for anyone thats had the issue. i have a built ls and am running a griffin radiator with a dual fan setup. i forget the fan maker. but the car is slowly creeping up in temp while idle. i replaced the thermostat but still the same. i have since ordered a 160 degree tstat and am going to try that. Any suggestions? also the front drive kit is a holley midmount kit with a new waterpump aswell. system was completely burped.
