Anyone else having cooling system issues after modifying their benz? In the performance section the cooling system doesnt get hit on very often but i seem to have run up against that point that i am creating more heat than my cooling system can dispose off. I have been noticing that while im at wot the temp slowly climbs past 80 (only after the tstat is open and the radiator is warmed up) and when i let off it returns to normal. anyone else experiencing this?
