Well I got to thinking about all the different ways to heat an engine to make starting it easier in the cold. I even went and bought a block heater and decided not to put it in. Too messy and PITA to get to those rear freeze plugs. Stickon pad heater? Too pricey. Tank heater - pricey too. Dipstick heater? Has it's pros and cons. Skillet heater? WTF is that? I'm gonna rummage thru the kitchen tomorrow and see if the wifey wants a new electric skillet. If so, I'm going to take the old one, cut off the legs and sides and wedge it up under the oil pan on my 743. I figure 250°F on the control knob should be about right... Whatdoyathink?
Heat is heat and it all helps. Block heaters are the best because they heat internally and the coolant circulates around the engine to spreading the heat out. Heat underneath help greatly too, but takes longer.
The onan on our welder used to get a forced air contruction heater up against the flywheel fan forcing warm air through the cooling shroud and over the jugs, those fins pick up heat as fast as thgey disapate it.
Even a heat lamp and a tarp.
Also synthetic 0-30 or 0-40 oil.
Remove any drag on the engine if possible.
Wow a C5 running with just a dipstick heater at -28, must of had a Deutz in that one!
