Insulated Engine?
Since I now have a block heater in the truck, it got me thinking...How about insulating the engine compartment?
It doesn't really make sense to heat an engine that's just sort of out there in the cold, right?
My wife's Pontiac Sunfire has the same GM 2.2L engine in it, but her car warms up amazingly fast. I think part of the reason is how tightly the engine is crammed in that car.
In my truck, there is lots of spare room (so you could fit the 4.3L V6 in there..) and the truck is higher in the air than the car. In other words, lot of places for all the heat to get back out.
Has anyone added insulation to the engine compartment? (other than just a thin sheet on the underside of the hood) Would this help the block heater work better? Make the truck warm up faster? Any concerns about overheating?
I have heard that the Prius has a thermo-bottle that the engine coolant goes into, so the engine is warmer faster later when you go to restart again. Wouldn't insulating the engine do this as well?
Call me crazy, but I am wondering.
