Dex cool or Prestone

[meissen]

From another site:

BeCoolant features a new-generation biodegradable, propylene-glycol formula that protects cooling systems and aluminum components down to -26F. Its self-sealing capability is ideal for sealing hairline cracks in aluminum engine blocks and cylinder heads.

BeCoolant provides up to 300,000 miles of extended coolant protection, and is ideal for Corvettes, as well as all performance and severe-duty applications (including diesel-powered tow vehicles and RVs).

Made in the U.S.A., BeCoolant is compatible with all types/colors of coolant, it’s packaged in recyclable, ready-to-use one-gallon jugs, two-gallon master packs, or five-gallon pails (seen here), and is UPS delivery approved.

Best of all, BeCoolant doubles a BeCool radiator’s factory warranty. (How cool is that?)

Go Green

I have had some bad things happen with Dexcool like blockages and eroded gaskets.

Just a reminder, you should use distilled water with the green stuff or you will still get corrosion.

where do you pick up becool at? Any auto place?

[meissen]

I got it from them when they were at the Meet & Greet - but I believe you can get it at the store or order it off Summit.

I'm sick to death of those little chunks that come up in dex-cool. Almost looks like oil in the coolant and very misleading.
