Hey guys. Just wanna be sure I'm not missing something and be sure. Yes I have checked as many old threads as I care to. Here it is. Water pump replaced 8,000 miles ago. No leaks. Normally the sky 2.4 runs 190° to 200°> Live in Florida. Today was about 97 in the sun and in traffic, AC on, stop and go it climbs to 219 over time. I stop at a store for 7 min, get in and start it and it reads 225° which quickly dropped to about 210° when I got moving. My mechanic is certified and has worked at several dealerships for a long time. He says that General motors built these cars to run between 200 and 230 And I should not worry about this. What are your thoughts?
