Help! Truck running hot.
Lately my truck has been running a little hot. Not pegged out hot but just over the middle mark on the temp gauge. The thing is it fluctuates between normal and above the middle mark. I cant seem to figure out what it is. Ive got a good coolant level, replaced thermostat, rad cap, fan clutch seems in good condition. Next thing i can think of is something wrong with the radiator or water pump? The truck is a 95 with 4.0 OHV. Any help is greatly appreciated!
