Stern warning about antifreeze
Im just flipping this out for your guys input I have a friend who is a very good 30+ year mechanic, working at various locations including a stint at a GM dealer. In a casual conversation the other day, showing him my old LIM gaskets and talking about the job, he observed a bottle of yellow, any color, any make, any car antifreeze sitting there. He says, you didn't put that in there did you? I said I sure did. Because I had heard that Dexcool was bad news. He said that the any color any make yellow was a top off only and not to be used as a stand alone. He said there are plenty of documented cases of corrosion to radiators, heater cores and other damage that was supposed to be caused by this kind of antifreeze.
He went on to say that the newer generation of Dexcool was the proper stuff I should use and to change it every two years.
Im quite surprised by this.
And let me reitrerate, this guy is a very good mechanic who has been around the block, seen lots of stuff and is still currently employed at a full tiime independent shop. And he has nothing to gain financially or personally by telling me this. He is convinced that its bad stuff.
Any body else hear anything like this or of a newer generation of Dexcool that is improved?
