I know I got scared when I used "another" coolant and then read about how detrimental it is to use the approved coolant with all the anti-corrosive agents and such. I didn't want to take a chance with the intercooler. It may be coincidental but it does seem a fair bit of the failures have had other coolants involved. I immediatly flushed and restocked with the correct stuff. Same with the tranny fluid; as I was uneducated, i bought what Chrysler sold me. Had to flush and put the latest Merc fluid in to solve my shift problems.

I think I will also adopt the BMW canister so that I may moniter the H/E a bit closer. cheers
