X2 Killerbee, dump the DEx-cool it is junk, flush your system 4-5X with a vacuum type system and replace with a HOAT coolant.

DOH! Youre right, I missed that too. That barely meets Ford requirements for the 7.3 Powerstroke, and a few on TDS, I know, used it with decent results but had to accually add SAC to it out of the bottle.

Which reminds me, is the Napa additive capatible with Dexcool? I have an unopened bottle thats like 4 years old, think its any good?

Water is barely compatable with Dexcool, LOL.

I wouldn't.

it is hardly ''synthetic'' like they [GM] would have folks beleive....
