I've read a few too many reports of bad head gaskets in Chevy Venture reviews but it sounds like it revolves around a %22pink antifreeze%22. Is this standard on the 2005 model%3F
Its not just the minivans its pretty much every GM that ran dexcool from mid/late 90s to mid 2000s. The dexcool turns into an acid and eats away at the intake gaskets. They say it only affects the 3.1 and 3.4 but I have replaced the intake gaskets on the 3.8 and 4.3 where the exact same thing happened. The best way to go about fixing the issue is to have the intake gasket replaced with the doorman gaskets made out of steel and a heavy duty rubber before the gasket fails and have your coolant flushed every 30,000 miles. I would rather own a GM that will need a $700 intake gasket replaced than own a ford that could catch fire due to the abs module leaking brake fluid or a dodge that will need a new transmission every 60k miles.
