I don't know if this product has ever been talked about but with all the problems with cooling on our Clippers take a look at the info on it go to firefreezemotormax.com it impressed me (//images/smiles/icon_smile.gif)
There is another product that that works excellent in the cooling system. It is waterwetter. See www.redlineoil.com. (http://www.redlineoil.com.) Their synthetic oils are worth considering.
We are in the process of installing a Derale transmission pan cooler to help with the transmission temperature. Purchased for less than $70 delivered from http://shop.store.yahoo.com/ak-dist/tranpancoolb.html. (http://shop.store.yahoo.com/ak-dist/tranpancoolb.html.) We are also adding a trans temp guage and synthetic oil at the same time. We we will mount the temp guage in the new transmission pan.
