installing a block heater

Hey all,

I'm moving back to Montana and am thinking about installing a block heater in my 2000 4.7 WJ limited. I realize that it's spring and I won't need this for some time but I have a friend that can supply parts while I'm still in Washington. Has anyone done this before and is it relatively simple job?

Most block heaters i seen replace a freeze out plug on the engine block,Depending the engine it could be easy or a nightmare.

Check out Kat's heaters. They make all kinds on heaters for cars and trucks. If you check their catalog, it'll tell you which is best and where it goes on the engine. They also make heaters that go in the radiator hose. I really like their battery wrap heater as well.
