Tonight I will be removing the bimetallic strip from my viscous fan and seeing if I can rebuild it. I found an equivalent to the Toyota Silicone oil at the local hobby store. With the R/C cars, they sell several weights for R/C car shocks. It is about $4 for a 2 oz. bottle. I bought the 100 wt of 100% silicone oil, which I believe corresponds to the heaviest weight Toyota sells.

Also, there are many types of syringes and pumps available, that are used for fueling model airplanes. For about $2, I bought a plastic syringe with a plunger that will fit the hole in the fan.

Question: will a blowdryer give off anough heat for removing the bimetallic strip? I have a propane torch, but it is harder to regulate and I don't want to warp the fan clutch.

Thanks,
Matt

Will the RC silicone stand up to heat?

That's a good question. It is 100% silicon oil, 100 wt., but the R/C application isn't heated, so whether or not it holds up in the fan remains to be seen.

I won't know the answer for a couple months, if I know then. First it will have to not leak out and the rebuild will have to make the fan do its job. If it fails, I'll probably go with Carl's electric fan set up.
