I have read the suggestions given for the engine over heating problem and I keep coming back to the fan clutch, even though the history suggests otherwise.

THe fan clutch in my car came from another 240 wagon which never over heated ... never. The fan clutch from my car which I put into the other 240 does not appear to be causing over heating. THe almost inescapable conclusion is that it can't be the fan clutch.

However, today I ran the car at idle for about 15 minutes (after changing the coolant to a predominately water mixture) I was dissapointed to see the guage rise from the 7:00 o'clock position (I have a low temp thermostat installed) to the 11:00 o'clock position. Once I knew the engine was fairly hot, I placed by hand carefully on the revolving fan. It was very easy to stop the fan's rotation. It took just a small amount of contact from my fingers.

I assume the fan is suppose to engage when the engine is hot, so I expected to find the fan clutch driving the fan. This would appear not to be so.

Any comments? Is this a valid test for the fan clutch or must the engine be revved up to do this test. THe engine idles fairly high, but I do not have a tachometer, so I can't give a precise report on this.
