Default Help - Cooling System Problem
My SPF is #1399, made circa 1999, with about 6K on the engine. It has a Southern Automotive 351W & Tremec 5 speed. It always ran on the cool side, with the fans coming on rarely around 94 deg C. In colder weather it rarely got about 85 C, even when idleing. All of a sudden, on a cool-weather run with very little stop-and-go traffic, it overheated (without the fans coming on) and warped the head. I suspected that the thermostat (180 degree F I think) froze up. Well, now my mechanic has resurfaced the heads, put a cooler thermostat in (160 F) and it is still running up to 115 deg C with the fans coming on intermitantly, but not always when they should. Any ideas?
