    I have a 2001 PreRunner with 180,000 miles. In July of this year, I had the timing belt, water pump, thermostat replaced. I have since put appx. 2000 miles since the replacement. I have towed my 16 ft boat twice. Both times overheating issues. Since I got the truck back, the temp. gauge seemed to be a little higher than normal. The first overheat with the boat, I limped to the parts store and bought a new radiator cap, I had water/coolant boiling out of reserve. This second overheat, in my guess was very very close to overheating, but didn't hit the hot mark, I did not have water boiling out reserve this time. I climbed under the truck to check things out. I found a water line I'm guessing, that maybe went to the water pump nipple, plugged with a bolt and hose clamp and......and.....a 2 wire sensor near the driver side of the water pump, oil filter area, the sensor was broke, wires pulled out of sensor. I took vehicle back to mechanic. They fixed the sensor.....said it was the oil sending unit! The hose that was plugged, they say it is some kinda smog control, and its no big deal! Before any replacements, truck ran fine, never overheating......Any opinions or suggestions would be helpful!

    Back again.....ha. Got the right water pump put back in with the bypass hose hooked up, all back to normal....until I pulled the boat. Flushed the radiator with Prestone flush, replaced thermostat just to make sure, pulled the boat about 10 miles....overheating. The radiator fluid, flush, was pretty clean....real clean actually. Fan clutch feels tight when cool, spins freely when warm....time for a fan clutch?
