Does This Engine Temp Look Normal?

[Don H]

Looks a little hot but maybe not?  My truck seems to run fine(4.0 HO) but this gauge still makes me nervous.  It was driven about 12 miles and the outside temperature was around 70 degrees here in Atlanta.   Thanks for any info! I tried to follow instructions for loading images from Photobucket but not sure if it worked?

Check it with one of those fancy infrared thermometers.  Aim it at the thermostat housing and see what you find.

Make sure your coolant's full and not leaking. Also, if you have a big enough leak, especially towards the top of your rad, eventually your cooling system will stop sucking coolant back in from the overflow bottle. That was my experience this summer.

:agree: If the gauge  is accurate, then as long as it's not in the red you're OK. Got to pull out my Harris Stamp catalog and identify the reddish one with the canal on it. Don't recognize it. It's not the Suez so maybe the Panama?

That's too damn hot for an HO mate IF the gauge is accurate. That's about where my stroker temp ran during break-in. Since then the needle has stayed vertical except in 90+ degree days when stuck in traffic. What were the conditions when you took the pic?

Hi thanks for the input!  I just got home from work after driving 12 miles.  It wasn't particularly hot outside, around 75 degrees.  These were the gauges I pulled from the junkyard (off of a 1992 Cherokee) to replace the idiot lights.  Installed new oil pressure and temp sensors for gauges.   Hmm.. maybe Apple with Safari doesn't work with uploading photos?

"Check it with one of those fancy infrared thermometers.  Aim it at the thermostat housing and see what you find."  

 

...sounds interesting, I think I'll look into buying one of those.

Bought a Ryobi TEK 4 infrared temp detector.  Gauges appeared to be showing around 230 on the dash while the Ryobi infrared gun was showing approx. 220 around the thermostat after about 20 minutes of idling.  I had the A/C on too.  Top of exhaust pipe was around 450 degrees.  Sky was around 1.2 degrees (supposedly doesn't measure accurately beyond two feet) and leaves on trees were about 75 degrees.  I can't wait to take it to work to see who the "hottest" chick is!

If you need a instrument to tell you who the hot chicks are, then I'm afraid finding them ain't going to do you a bit of good. :yes:

[Don H]

hehe.. some of them think they are hot, but the Infrared may disappoint them!

Don't you have an OE "pointer" that goes near vertical in the presence of hot chicks?

.

Mine's still working perfectly after giving years of good service.

This is the thing: Jeep gauges always have been for amusement only. Any resemblance between them and reality is purely coincidental and sure to get you in trouble if you always believe them.

And don't use any aditional sealer on the threads of the senders as this can change the readings. They need to ground good.

Also too hot for a Renix. With the standard 195-degree thermostat the gauge should show 210 degrees (straight up, mid-dial).

For some reason I stopped getting notifications of posts, so this is old news.

 

 

Did you loosen the temp sender to allow the trapped air to escape?
