Engine oil temp

[renyren]

I was wondering what the normal operating engine oil temp is. This weekend while towing up a grade it climbed to 216 and the AC stopped blowing cold. As soon as I got to the top of the hill temps droped back down to about 197-200 and the AC started blowing cold again. Is this normal? My trailer is only about 6000 lbs.

I think I might have posted on another of your threads elseware...

here it goes again just in case.

216 sounds about normal for towing. Are you measuring oil temps with AE?

Sounds right to me on the temp. I see 210 ish pulling my 12k 5er when its not too hot out and I am not working it too hard. When it was 105 out I would see 220 and i did see 225 once when i was working it hard.

The ac is another issue. probably low or high pessure switch tripped.

I am using a scangauge II for the oil temp. does you AC even stop blowing cold untill it cools back down. Mine cooled back down right away after getting to the top of the hill. What is the max oil temp should be before you need to pull over?

when I hit 225 my ac did not cut out. My fan under the hood was locked and making a ton of noise!

I have read people saying 250 is about the limit. I do not know for sure...
