Reviews of GENERAL MOTORS antifreeze

Dexcool is for GM vehicles. There were problems with some of GM's vehicles, so I would avoid it. As a Volkswagen owner, I would not use Dexcool in those either. Do not waste your money on this GM crap!!

I just did this because I had to replace my thermostat. Has been fine for 1000 miles now, most of which were hard miles (I have a company car, so the LR3 either gets driven in stop and go city traffic, or off roaded, depending on the weekend). I used GM Dexcool. No issues.

mixing ANYTHING with dexcool is a bad idea. Sister has a Chevy Malibu, takes dexcool, was low, boyfriend put in universal, an her car over heated. Told her to take to closest shop and have them flush and fill with dexcool. Hasn’t had any problems since. Do not recommend putting anything other than dexcool into a dexcool system

the GM dex-cool is fucking garbage. You do not want that shit in your car. Take that jug and have it recycled.

Like all the other Malibus of this generation, GM sent this one out into the world filled with Dex-Cool, a long-life coolant the color of vodka and grenadine. Dex-Cool was supposed to up the coolant change interval to at least 100,000 miles, and prevent corrosion better, and generally be a better choice for aluminum parts than the green-death ethylene glycol antifreeze that we're all used to. Dex-Cool also had the added bonus of liquefying silicone rubber, which unfortunately was the material that GM used to seal the coolant passages between the heads the intake manifold.

i use the GM red coolant in all my VWs (gas and diesel) without issue.. it IS IMPORTANT to flush the entire cooling system very good before switching from green to red tho.. they do not mix.

I wouldn't do it. Take this for what you will, but our local GM dealer was switching alot of cars back to regular Ethelyn glycol (green antifreeze) after they had too many warranty problems with Dex-cool (propylene glycol). Which included seal degradation mentioned above, erosion of plastic parts (including intake manifolds, waternecks, etc.), and clogging due to formation of brown sludge produced by the coolant. On top of that, I work in a parts store and I see alot of premature failure of waterpumps, radiators, and gaskets that seem very much related to the use of dex-cool.
