Yes but, run something like prestone cooling system flush through it at least once. The bottle will have directions on it. I know that GM vehicles love a good clean cooling system. One thing to watch out for is if dexcool has eaten the intake gaskets, filler neck and water pump seals. I have had to replace them on our suburban, a friends and soon I will be doing a friends 2000 blazer with the same cooling issue.
