Observations from Friday's tow.

Since, dad doesn't have a big pickup, I got to do some towing for him. Borrow 32ft PJ triple axle trailer, and go pickup 2000 ft of guard rail, 200+ miles away.

Observations
200-210 seems to normal temps on flat ground pyro running 900 abouts
225* engine fan kicks in
227* cruise control kicks out
229* engine derates itself
231* Highest temp I saw

1200* is highest sustained temp never got any hotter

For those wondering, I didn't get to scale it, but susposedly 13,900 lbs on the trailer plus trailer at 7000 and my superduty at about 8,000 eqals 28,900 lbs GVW (+/- 1000 lbs for error).

Sorry no pics, unless you want a pic of the pile of guardrail and the empty trailer.

I forgot to add. I'm now an inch or so below the MIN line on the coolant bottle. Approximately how much coolant is this? It was right smack dab in the middle of MAX and MIN.

Also how long does it take for a coolant filter to bleed all the air out of itself so it's full?

wow nice job on the info

The most I have pulled is a 15k fith whell plus all the stuff. nevery have I hit over 220 on water yet I did hit 230 on oil tho. that was with only the edge chip

Now I'm confused. Went and bought a gallon of coolant, because it was low. This morning it's sitting at MAX. WTF going on? It's confusing me.

when its hot, the level is lower since its under pressure. and when it cools down, it can go back up
