so i thought i fixed the problem... no such luck, lastnight the radiator sprung a leak so i put a new one in today, with a perma cool fan and one stocker. around town the cars fine no issues but once i'm on the hwy and at a steady pace like 75/80 it wants to start climbin and once i get off an exit i start to heat soak. how do i solve this problem. i dont have coolant in my oil or oil in my coolant i changed both. i just want it fixed already.
