1972 Peterbilt 359M with Caterpillar 1693TA, Cold Start, Part 1

Starting the Legend on a beautiful fall day. By the way it starts you would think it is 20 degrees outside. It was in the mid 60s this day. You have to use the preheat glow plugs even when the temp is in the 70s. The system works very well when used properly. I have started this truck in below zero temps without being plugged in with no problem.
