Default Checked out a 2004 Impreza, just a few questions

-If it was a 2004, it would have came factory "installed" at first with the coolant conditioner?

-2004s would be an external leak?

-Car will be mostly winter-used on 15-20 minute drives for work commuting.

-My climate is like no other winter in the world, its the coldest major city in the world, Winnipeg Manitoba. Heres a climate chart for an idea


I'vr had some bad experiences with foreign cars handling Canadian/Winnipeg winters. Could you please give an honest opinion on how these cars hold up to extremely cold starts?

-Basically any other opinion would be appreciated. Its a wagon model. Is DIY pretty managebale as well?

there are some that develop piston slap in cooler temperatures, im sure this would be exaggerated in the frozen block of land called Winnipeg in the winter. Good, relatively new alternator and battery goes a long way in keeping the electrical side of things strong for cranking.

If it has an owners manual, chk for the recommended oil viscosity for the season. If it does not, chk here.

i have an 05 rs and live in calgary alberta. No problems with cold starts but i have replaced the oem battery with an aftermaket one that has more cold cranking amps. On really cold days, the engine is a little noisy at first until it warms up a bit. I would also invest in a set of winter tires though. Maintenance on the car is easy, just follow the maintenance schedule.

I don't have much to offer, opinion-wise on the climate question.

DIY general mainenance is generally very easy IMO. The 2004 is a SOHC so spark plugs and wires are easy to get to. The oil filter is right there. The EJ engine has been around for over 20 years so they must be doing something right.

Good luck.

I would swap the battery for a better one, the OEM ones aren't so great in very cold weather. I assume it has the cold weather package (with a block heater)? If not, block heaters are like 30 bucks. Pretty sure most canadian cars have them stock though.

Honestly, the weather there doesn't sound terribly cold, a block heater and a good battery should be plenty. Even without either you'd probably manage just fine - I've seen plenty of cars start OK in -40*F with both the OEM battery and no heat.

I live in northern ia, by no means colder then you, but i have a block and battery warmer on my 2.5i it helps alot as we do get down around -20*f in the coldest weeks of winter. They are fairly cheap and easy to install. Under 75 us so that would be around 100-110 cad. Every car i have owened has been setup with a block and battery warmer and never had cold start problems except a Diesel Jetta that my wife forgot to put anti gel in the fuel. So get imho a block and battery warmer. here is a link were i got mine and they have them for 04's

My MY05 RS was purchased as solely my Winter car. The stock battery has been fine so far, with temperatures as low as -35C. I'll be replacing it this Winter as a precaution though. There is definitely piston slap on days below 0 degrees. Much more so when the weather gets colder than 0 degrees. The traction is great (I have 4 winter tires). Transmission (5 speed) is smooth, even in very cold weather. The rear defroster is weak and underpowered for our climate, and barely gets the job done on very cold days. Front defroster is adequate.

My car seems to burn oil, and always has (bought it used in '09 with 93km). Seems to use a quart every 4,000km or so.

Hope this helps. Anything else just ask ...

You can get nice little 120V heating pads at CanTire, about $80 each. I have them wired up to a bus bar with the block heater and have one on rear diff, one on the transmission and one on the back of the oil pan. You can imagine how thick 75W90 is at -40C. You'll notice how much it slows down while shifting until everything gets warmed up.

Have fun this winter. Don't get yourself high centred.
