Re: School me about Block heaters

heating the coolant is a LOT better then heating the oil. Heating the oil can burn the oil. Besides, warm oil doesn't help the engine start.

heating the coolant using a block heater means the HEAD will get warmer. Most of the water circulates up to the head.

Then when you crank the engine over to start it, the head is warm, top of the block is warm, vavles are already warm, and the truck will start more quickly.

If it don't run, chrome it.
