Thanks a Million Mark,

Good to have you on here indeed. New to this car myself and have a few questions to rest some worries. First I do understand that vettes have tendencies to run hot, I am told. I do however smell an occasional coolant burning odor when the car gets hot after some driving. Mind you, black car in Florida and what I mean by hot is around 3/4 mark on the gage, guessing around 235F if i am intrapolating degrees properly when stopped in traffic. However, returning to around 1/2 on the gage 190F more or less once I get up to speed. Being mechanically retarded, I did check the following..
Oil good, clean and serviced before purchases
Air filter, AC delco fair, not super dirty, but mostly yellow with some dirt built on, but not needing replacing.
Coolant reservoir ( passenger very front white tank) above cold line level slightly with good green coloring.
Question...
1. All normal don't mess with it?
2. Might want to consider a change in the thermostat to have run cooler down here?

Thanks,
Manny
