We had a fan clutch that really unresponsive, I thought about it and looked at the bi-metal spring. Then I washed it out with a spray can of something and then it worked better. We also had one lock up completely.

At this time, I have forgotten where we were going, but at first my thought was that I was being chased by a DC3. Then I checked the tach and we were in top gear. Then I got on the web (Mary was driving) and found that a Autozone not way off our route had a clutch part number that should work. We were going past Amana Colonies, so we went in there and Mary went into that neat general store while I waited with the engine room door open, the A/C running and the tools at hand.

In this case, it was amazingly convenient to have the clutch locked up tightly enough that I could actually pull through a compression to get at what I needed to R&R the fan clutch. Putting the replacement in was not as convenient. I didn't save the old part.

I do love this new fan control and will be collecting data about it when we head for Chippewa Falls.
