I don't think you have to but you will have it coming at you while replacing it with the new one. And it is antifreeze that it heats.

Tracy, I picture this thing being a rod heater, does this thing run down a port in the engine,along a coolant jacket, or how does it work??

It is similar it how a hot water element works it heats the coolant keeping the block warm which will inadvertently keep oil in the block warm.

Are you sure it is bad? Ohm check it.. it should have about 40 ohms if operating properly. Check it at the block.. Read alot of posts where the cord/plug were bad..

if the new heater came with a separate cord, just try swapping that out first!
