For those with aftermarket electric cooling fans

The unit I have uses a temperature probe that pushes into the radiator fins to sense when to come on. I have never liked the temperature that the unit was turning on at even though I had it dialed as low as it would go. It has an adjustable "on" temperature. Of course it has an AC compressor over ride to come on when the AC is on. But when that is off, it has to sense the actual temperature of the radiator.

So the other day I came up with the idea to put heat sink compound on the probe. What a difference. It comes on about 30 degrees sooner then ever before.

So if you want better sensing of temperature, try heat sink compound. Available at any Radio Shack.
