ps2cho, if you want, I still have my Spal electric puller you can try out and see if it works for you still pretty new, only had it for a year. If it works for you then you can buy it from me. Although, I did remove it because I didn't think it was keeping my temps low enough. I am using the viscous fan, which has done better.

Also, why is the Sachs clutch better or updated? There are only 2 things that I can think of what would make the Sachs better or updated, and that is either sooner flexing of the bimetallic strip....which would not mean anything unless the thermostat had opened up allowing the coolant into the radiator, or the viscosity of the silicone fluid has a higher weight. The latter would seem more likely as I have drained out a clutch and filled it with 30k silicone and when the clutch was locked, it was spinning at 100% of speed vs 80% with no slippage.
