I have a 92 chevy truck with a 5.7, I use it for snow plowing and have for years. But it overheats on the freeway and is getting worse. I have replaced the thermostat with no luck and flushed the radiator and no rust came out and has good flow. When it overheats as soon as I pull off the freeway the temp jumps back down really quick. It does not overheat in town?
have the same problem?
