Be Cool Coolant

[HummerJim]

Has anyone used Be Cool Coolant? They say it is superior to anything out there and is used in diesel trucks such as Kenworth from the factory. I saw it on the Speed Channel and they are claiming it mixes with GM antifreeze without any problems. I know some stuff will make the GM antifreeze clump when added. I'd never heard of it before and I've heard adding Prestone can mess up the GM antifreeze.

I'm not sure if GM still uses Dex-Cool in the 2008 and newer models, but you never want to mix the green stuff with Dex-Cool. There are several states with class action suits in the works concerning GM and Dex-Cool. Although GM says it's been tested and the suits are without basis, it's been known to eat up gaskets. There's also evidence of it eating radiators and clogging them when mixed with the green stuff and even the red stuff.
Prestone® Extended Life Antifreeze/Coolant is compatible with ANY antifreeze/ coolant – regardless of color – for use in ALL makes and models of cars and light duty trucks. They even say in their literature that it is compatitble with GM Dex.

I know the company is all about top quality. If the coolant is as good as radiators they sell, you are going to want to flush and forget about replacing your coolant for like 7 years or 300,000 miles!
