How hot is safe for my engine

[pest1688]

Hi how hot should my engine be running. my 318 runs at 180 to 190 with ac off and 190 to 200 a/c on when temp outside is 80. I notice it runs hotter 190 on the hywy and around town 175 to 180. Are these numbers acceptable? Thanks!!

Temp range is fine. When it starts to creep over 200 then pay attention to it.

I agree.....not a biggie. It's not even boiling temp yet, and that temperature is measured as it's leaving the engine, up @ the water elbow, right? I don't like anything over 200 and definitely 215 (mostly 'cuz it increases the likelihood of pinging) I go nuts when it just keeps creeping up......220, 225....230.

Dual electric fans on a be cool alum radiator will anyways keep that engine cool!

Thanks a lot guy's your always so much help!

With good antifreeze and a good radiator cap (and no leaks) it won't start boiling until its over 230.

To me, it sounds like you're running in a pretty good range. I don't think I'd spend any money to change it.

i'd be more concerned if it ran at less than 190. your smallblock needs to run at around 190 to 200. not a concern bud
