    OK, some updates. I think that there is nothing wrong with our installation. It only heats the water jacket, obviously, and this is what it does very well.

    I have directed its exhaust output (not so hot, maybe 250-300F at most) a small distance from the oil pan to also heat the oil pan as it runs. Realistically it only makes the oil pan a bit warmer, maybe 10 degrees F warmer. The exhaust tube is not UNDER the oil pan and would not get much oil dripped on it.

    That is way too small of a heater for a truck. It is a max 5kw heater and doesn't really heat much, it is the size of heater I have in my pickup and with the -20 degree weather we had, it barely heated the engine and fuel tank up.

    You need at least 7kw to warm it up but really need 9kw heater for a truck.

    webasto makes a 9kw heater but they also make 12kw heater that would work if you setup heating the oil pan.

    they make a oil pan heater just like a block heater. take one of the oil plugs out and put heater in. plug up to power cord.

    I tried it yesterday. It was about 2 degrees F. Ran it for an hour (was doing something else at my warehouse in the meantime). Truck started like it was July.
