Okay so I was at a fast food place today with my Suburban and while waiting in line I notice the temp gage getting way up there. I'm talking over 220 and slowly climbing!!
I know it's full of antifreeze and water when I replace my top hose I topped it off. It has the flex fan and no clutch at all. But once I got back on the highway the temp started to drop back to normal.
What should I do?
Flush the raditor or what?
Thanks.
