I did everything my search said to do. My sidekick is over heating in the mountains at low speed, four wheel. I opened and filled the fan cluch with oil. The thermostat is fine. The water is moving in the radiator so I guess the pump is ok. But the Prestone boils out when in the steep climbs.
What else can I do. Thanks Jimmy

Does it ever over heat when driving it normally- flat ground, 2wd? When it over heats does it peg your gauge, and are both the radiator hoses (upper and lower) and the radiator all about the same temp? The reason I ask is because water movement in the radiator doesn't alway mean the water pump is pumping. Most water pumps just have the impeller pushed onto the driveshaft and I've seen where the impeller becomes loose from the shaft and doesn't spin.
The water looks like it moving and is moving but only because the water or coolant is boiling in the engine, and boiling water moves. Also how are you determining the engine is over heating? by the dash gauge or is it pushing fluid out the over-flow? One more thing is, have you ever washed or blown out the debris from the radiator fines so its getting good air flow through it? I hope something in my ramblings helps you some how!

It never overheats in 2 wd or highway or flat ground. only climbing steep mountains. It boils out the overflow and the coolant boils out the rubber tube when the guage in over half. Dont have a clue the temp of the upper and lower hoses. I can hear the coolant boil when I stop. I clean the radiator regularly and also the radiator has been cleaned and flushed. New radiator cap. Thanks Jimmy

Had a similar problem... be sure your thermostat is opening. Mine stuck shut once, only overheated with high rpms, then would cool down when I slowed down. I thought they would only stick open, not so apparently. I took it out and put it on the stove in some hot water and sure enough, stuck closed. New thermostat solved my problem. An "expert" told me the radiator was plugged up. eerrr >:(
