Intake Heater

So I have an idea. . . .

Since the intake heater is pretty much worthless since it hardly ever turns on, how about wiring it to a switch so you can turn it on and off? Would it help warm the truck up quicker and stuff if you could wire a switch to it and actually make it come on?

I don't know. Just an idea.

I'm pretty sure its just to help the truck start up faster, not to warm it up faster?

It doesn't even function at warm up time. It's for extended idle in cold areas.

Intake heater??!?! that's about the dumbest thing I ever heard of.

Cars run much better with colder, denser air.

Heater...whose stupid idea was that??


EDIT: Ever heard of a Hot Air Intake? Cuz I sure haven't. I'm still stuck on what a genius idea this is. :hehe:

Not so for a idling diesel in cold weather my friend......cylinder head temps can drop significantly at idle with no load placed on the engine and actually get cold enough to cause carbon and gum buildup on the valves....thats why the high idle system is in there as well as the intake heater to help boost cylinder head temps for sustained idle in cold weather with no load.

So since it hardly ever comes on, would it be worth wiring a switch to it to turn it on when its cold out to help warm up the truck? Would it actually help with anything?
