I'd say what you're seeing is pretty normal. An engine is always hottest right after you shut it off. If you go back in five minutes and restart , it 'should' be showing hotter than its normal operating temp. If it's not overheating in traffic with the a/c on at 95 degrees outside air temp, I'd say you don't have a huge problem. Others welcome to chime in on this one.

hoter yes but for it to just abought peg the gage

From what I've seen on these boards,, the factory gauge is not always the most accurate. The actual 'heat' shown on the gauge may not be really quite as high as the needle implies. You might try a different method of testing the heat on your engine right after you shut it off.

You could go and pick up a Autometer or other brand temp guage and see what it tells you. I plan on replacing my temp & oil pressure with aftermarket guages just to keep a better eye on them..
