My fleet just started overheating. I changed the water pump and thermostat about 5 months ago, Since then i haven't had any major problems as far as cooling. My A/C fan comes on when the compressor pops on. The large fan seems to come on when the thermostat opens. Whats do you think?
As L98 said, on this engine the water pump is cam driven, on my 94, there is a splined shaft sticking out from the cam cover about one inch. There is a matching splined shaft on the water pump, also sticking out about an inch. A little splined coupling about 2 inches long connects the two shafts and transfers power from the cam to the water pump. On mine the splines on the water pump end of the little coupling wore out and the coupling was spinning on he water pump shaft but not turning the impeller. It made a whining noise. Splines on water pump were almost worn out so I changed the pump also.

Assuming you replaced the radiator with new or refurbished. You probably need to replace the thermostat. It is usually located on the engine block in a housing at the end of the top radiator hose. Probably just two bolts in the thermostat housing.

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.
