580sk wont warm up

mardi 20 mai 2014

Hi guys my question is that anyone knows what temp of thermostat is suppose to be in the 3.9 Cummings? It has never got to a quarter gauge on the gauge so I checked it with a heat gun and 175°f is all the hotter it gets under hard conditions.I have never checked if it has a t stat in it.I just got to wondering about this because it seems to be a fuel burner .what I mean by that is it will burn 20-25 gallons of the 33 gallon tank in a 8-9 hour day. This is based on a hard day working it.
