Engine temps.

[04FX4]

Ok so when I tow my travel trailer, I have been monitoring my engine temps and CH temps on my gryphon. My CH temps are higher then the coolant temps by about 12 degrees. When on the flats I run about 200 and going up hills it will go up to about 216 on the coolant temps. I am concerned but was wondering what other have seen while towing. My gauge on the dash never goes above the half way mark which makes me think everything is normal but the gryphon has me thinking about it. My thermostat is a 195 and my trailers weight empty is about 4000lbs. Should I be worried or is this normal. I am going on a 2 week trip and dont want to have any problems on the way.

Normal.

The ECT is an inferred reading from the CHT. The ECT does run 10 degrees cooler.

So are the temps I am seeing normal as well?

They seem normal.

Write these down on a piece of paper and put it in your glove box.

Unsafe temps.

ECT=220
CHT=240
TFT=215

A CHT of 258 will send the truck into failsafe limp home mode.

Hope this helps.

I agree with Lars 100%. When I tow my trailer up a long hill (like the passes in the Colorado Rockies, or the 8000 foot climb we'll be doing tomorrow when we take our 3600# trailer up to Mt Graham here in AZ), I regularly see 214-216 on the CHT. I simply don't monitor the ECT, since it's inferred. And, like you, my dash temperature gauge NEVER moves above "slightly below the halfway mark".

If you want a real thrill, monitor the oil temperature (if you have that capability). I did for a while, but it was bad for my nerves, so I quit.

I'd hate to imagine what the oil temps looks like, I never looked, but will have to when I get mine back.
Also, I didn't realize the ECT was actually inferred.... interesting.
