Guys I don't have the owners manual. I have been running Dexacool in it for about 5 years now. I think it's time to change it out. With all the Hoopla about Dexacool, what is the type I should be running ? Funny thing. I use to have a radiator leak ... It self sealed .. I figured the Dexacool hardened in the crack it had in a weld where it was leaking. Thanks for any advise.. WD
