Engine Block Heater question
Hi Experts and Expertettes -
I wanted to order an engine block heater for my H3, but was told that I needed to order it from the factory, i.e. order a new truck with that option. That it couldn't be added at the dealers. Can anyone tell me why? Is it embedded in the engine or something?
Thanks

you can get them from dealer...all you do is remove a plug on left side of motor and screw in heater...by the way it is a 17mm allen bolt style hole.

Re: Engine Block Heater question
I just found a little note that says 3.7L engine in 2007 H3 has "New cartridge-type engine block heater, which fits neatly into a specially machined block orifice; for use with available engine block heater."
http://www.gm.com/company/gmability/...ec_062006.html
Are you thinking of that? Can a 3.5L engine's heater be added after delivery?

I have never looked at or delt with an 07...3.7. I was talking about 3.5, which I have done. about 3/4 up the left(drivers) side of the block is a hole with a plug in it. All you do is unscrew plug(you will loose antifreeze) and screw in block heater. You can access this through left wheelhouse.
part # for heater is 12586687 retail $21.23
part # for the cord 15134398 retail $35.58

Re: Engine Block Heater question
Aha! Really? Cool. Thx for the part #s. I shall visit my friend neignborhood dealer to see what their computer says about these. Remember, he said they couldn't order a block heater.

Re: Engine Block Heater question
OK, dealer can get parts. part they can't say if they can do the job 'cuz computer doesn't definitively show where it gerts installed. And the parts are not seen on a specific Accessories Page on their system, so they think (as mentioned earlier) that it has to be order with a truck.
They wondered, if the heater goes right into the block or into some other part (possibly water pump?) If it goes into the block, then they said the standard H3 engine should be able to have the heater installed. If it is in some other part, then perhaps a non heater truck doesn't have the correect part to accept the heater. (paraphrasing their thoughts).
So, does the heater go right into the engine block? Anyone have one installed after they took delivery?
Thanks.

Re: Engine Block Heater question
ok, heater plugs into the engine to heat the coolant. Search function works

So, has anyone had it done after delivery?

If they can't seem to get it done give them this... It is procedure for replacing the heater but is the same for removing plug and installing heater. Heater screwws right into side of the block.

Re: Engine Block Heater question
THanks! Now THATS why I love the forum and purchased a hummer!
It's a hummer dealer. THey were accessing some GM parts thingy on their computer. But because the heater wasn't showing on some "accessories" page, they didn't know they could add it later.
