Re: Coolant/Antifreeze question
If your peak is rated with Aluminum then your ok, my big push is to get people to consider using a radiator flush before refilliing.
I got out massive gunk and ran it out into a cloth to catch and see what was flushed out. The system ran better after that, and that was before I made up the supercooler. Back then I was running the stock H/E and had 12,000 miles as a second owner from a dealership.
If you care to look back in my many posts, there are photos of the stuff and all that, enjoy. Woody
