CR55
It's just a little surface rust!
I know this isn't a hotrod, but I need some help with my son's car. Its a 2001 Caddy with a Northstar engine. It runs fine for varying times then it starts running hot. He's had to tow it twice. The dealer checked it over and put in a new thermostat, he couldn't find anything else wrong. It still runs hot once in a while!Any ideas? The hoses are new and the electric fans are working fine. There are no visible leaks or coolant anywhere to be seen. I'm out of ideas...help!!!...CR
