The story is: The car started running hotter than I remember, climbing to 110 frequently. The aux. fans would kick in and bring it back down to just under 100. Thinking it was the thermostat, I changed it, but the car still ran the same. Next I ordered a new Behr radiator, and changed that. Still no change in the temp. Then the 'check engine' light came on so I went to see Enrique and he pulled the code: bad tranny vacuum modulator. He said I was ok to drive. At that time I asked him about the cooling issue and he said possibly the fan clutch. A couple weeks later, I was on the freeway and saw the temp near 120. I limped home and saw the aux. fans didn't/wouldn't come on. So now I've been changing the fan clutch, but the car still gets up to 100 degrees.


After reading Jim's site, It seems the fan clutch doesn't kick on until after 100 degrees, so I wouldn't know if it's working or not. On my Jeep Grand Wagoneer, when the fan clutch was engaged, the fan was hard to turn when the engine was warm, easy to turn when the engine was cool. The new fan clutch is pretty easy to turn all the time.

I never did think it was the waterpump, someone suggested it. The expansion tank does hold pressure, but I could use a new one.

I was having the car towed to Enrique this morning but AAA didn't send a flatbed and they are really busy today. I'll shoot for tomorrow.

Thx,
Dcraig
