My Niece has a neglected car that had the water pump replaced. I see rusty coolant residue from when the pump went out. It looked like the coolant was neglected and when they replaced the water pump they put in green coolant. So this should have Texaco Havoline, Prestone Extended or Zerex Extended Life coolant correct? The radiator side tank is leaking at the rubber seal.

I think you should do a flush & fill with Amsoil. And AutoRX it. That should take care of the leak. Maybe some SLOB for the extra moly? \:\!

I wouldn't take that article too seriously seeings how it claims that Dexcool is a propylene glycol coolant.

I've heard that particular factoid more than once. It's "common knowledge" in some circles. But that doesn't make it correct.
