I have a 1998 GMC Jimmy 4.3 liter with 151,000 miles 4w/d. I replaced the thermostat and clutch fan, the weep hole on the water pump doesn't have any sign of coolant. I can drive it in town and my temp. Gauge stays normal, then I travel on the highway and it starts to climb. If could help me out I would appreciate it. My oil doesn't look anything like a milky liquid, and no white smoke is coming out of my exhaust. :Mrgreen:
