I asked when I picked up my 08, dealer said they don't make one yet. i asked again when I went for the first oil change just yesterday, they apparently don't make one.

I'm a bit confused though, since I thought the new motor used the same block and was just bored out a bit and they increased the stroke to get the extra 0.6 L displacement. If its the same block, wouldn't the old block heater work?

It gets cold here in the winter (sometimes -30C or -40C) and I NEED a block heater.

I can't say for sure but I can't see why the subaru block heater, which is pretty much universal to subarus, won't work on your year. All it does is replace one of the coolant plugs in the bottom of the block.

That is a link to the attached install file. I have to say getting the plug out can be a real bugger. I've done it in the past when installing an OEM oil cooler. You need to have the proper allan fitting (14mm) which can be a chore to find.

The heater is basically an electric heating element (400W?) that is at the bottom of the cooling systems fluid. It heats the fluid around the elements, when the fluid gets hot it rises creating a convection current around the cooling system. The fluid warms the motor block. It makes it so the motor will turn over easier in extreme cold weather. Most cold climes have places in parking lots to accomidate people with block heaters. Until you've been to places that get super cold it's hard to appricate the need for a block heater. It also helps get heat sooner in the car.

edit: From a parts site:

Weird question, but what is the purpose for this heater?
ever been to Montreal ? :) It's funny to see parked cars with outplet plugs hanging from under the hood :lol:

More universal but waaaaayyyy more expensive is a autonomous gazoline heater from Webasto (Germany) - lots of cars in Europe have it. I beleive one can preorder Mercedes and BMW with Webasto heater installed at the factory.
