Engine Operating Temp
My question is what temp should an LS1 engine run at? I just bought a 2001 formula with an LS1 engine and the operating temp seems to run at right around 210 degrees. No overheating problems but I am courious of what everyones run at? Thanks

Thats about the hottest I used to see even in a Vegas Summer. The fans cut in at about 220 I think. Seems a bit warm for normal running to me.

I guess I need to be sure if the gage is reading properly. I dont know if the fans kicked in or not. I just installed this engine could be I still have air in the system. Thanks for the info guys.

The question is if you just installed the engine, what was in there before? If it was a smaller engine, you may have a cooling system that can't handle it. Make sure the radiator is clean. Vettes hav a tendency to collect "stuff" at the very top of the radiator and cut off half the capacity.

Factory settings - turn-on temps for the fans are 226° and 235°.

The engine came out of a 2000 z-28 camaro and it went into a 2001 formula. The only reason I am posting here is because C-5 vettes have the LS1 engine. I usually hang in the C-3 section with my 77 vette. Thanks for all help.
