So whoever had my f150 before me must have traded it in for a Chevy because I purchased it from a GM dealership. Regardless it has Dex-Cool in it and I was wondering if that will pose a problem for my truck should I be worried? Should I flush it and put in the regular ethylene glycol? Thanks guys.

 

If it was me I would get the Dex- Cool out of it.

 

X2 .. remove the dex-cool and flush.. replace T-stat after the flush and fill with motorcraft gold
