My first bus was a PD4501 with a 8V71. When I got it, the PO had replaced some hoses, so it only had water in it. It was getting cold, so I plugged in both block heaters. When it snowed a couple of inches, there was none with in 3 inches of the extension cord. I left it plugged in for 4 weeks - it cost more than $25 per week!

Antifreeze looked cheaper after that power bill !!!!
