Re: Can an AC Installed make the engine run hotter than before?

I agree with all the replies above that say 210 degrees is essentially normal. My 2006 Duramax fan doesn't even engage until the gauge reads 210 and antifreeze containers say a 50/50 mix protects from boiling to 265 degrees with a 15# cap. I would run it as is.
