Well here it is 11 months later and I'm finally finishing the "Forty Below Zero Deuce" project.
It was always my intention to add dual freeze plug block heaters, oil pan heaters and a float charger to the mix. I elected to go with two 600 watt freeze plug block heaters versus one large 1,200 watt unit. IMHO, the two smaller units spread the warmth throughout the block a little better AND one can be used to keep an already warm engine within starting temp. If the heaters haven't been plugged in for a few days then both freeze plug block heaters can be plugged in for a quicker warm up. The same rational plays for the two oil pan heaters. Given that I've got the pre-lub system I feel it best to keep the oil warm so the oil flows better and the pump isn't overworked.
Pics of the battery heaters have already been posted above --- here are pics of the oil pan heaters. The front heater is 450 watts and the rear is 150 watts. Sorry but no pics of the freeze plug heaters were taken. They are mounted in the front and rear freeze plug openings and for the record they are Car Quest part number 78266HTR. In case there is any confusion, the heaters I'm using were originally for a 1987 Jeep 6cyl.
As you can see from the second picture, there was a lot of cords to contend with. I added a control box behind the passengers seat. A gang of toggle switches allows the different heating devises to be brought on line. This may sound like overkill but you don't need everything activated if you're only stopping for a three or four hours. If, on the other hand, the unit has been cold all night you need a lot of power to warm it up without having to wait half a day.
The first switch allows for utility power to be selected, or generator power, or no (off) power. I have a 3,500 watt generator secured in the bed, behind the cab for those times when no utility power is available. There are switches for the front block heater, back block heater, front oil pan heater, rear oil pan heater and battery heaters. Also, Anywime the unit is plugged into utility power or is on generator power the float charger is running.
It's always been my intention to turn this truck into a dependable, reliable daily driver.
