Okay I own three diesel vehicles, car, truck and now a tractor. I never plug in the car and truck unless it is below -19 C -2.2 F. My tractor really sputters on start up at a couple of degrees below freezing and was wondering what the collective wisdom is on when to plug it in. I let them all warm up before use, lol.
Thanks
A lot depends on the individual engine. Our Ford 4610 and the NH are plugged in for two hours when ever the low temperatures are consistently below 40F. The NH TD95D is used for winter feeding and it's on a timer that turns it on two hours before I feed. I don't bother looking at the daily temperature for the NH because our temperatures can vary from -20F to > 50F during the winter. Leaving the block heater on for more than 2 hrs doesn't seem to make any difference in the coolant temperatures so I never leave ours on any longer than two hours.
Cold starting is the Achilles heel for diesels and I strongly believe that using a block heater saves a lot of wear and tear on the engine. the starter, and the battery. Our heaters are 0 .5 and 0.75 killowatt so if I ran them both for two hours a day it would cost ~$0.18 per day or about $5.25/ month. The added benfit is the NH cab warms up pretty quick when i have to feed.
