yep, check the manual. i'm guessing it'll say 90,000 or 100,000. def get it done before 100K i have heard of and seen (ford dealership i worked at) cars with broken timing belts come in but the fords were non-interference so they were ok. i think our EJ motors are interference so possible engine damage could occur w/ a broken timing belt (pistons smacking the valves).

The 2.5 liter is an interference engine, the 2.2 on the other hand is not. The belt should be replaced at 90k.

105k is recommended by subaru.
They must have changed that for the GD's, my owners maintence manual says 90k.

I belive the GC RS manual might say 90k as well. But when I worked at subaru their paper work said 105k, and I waited till 105k. It was also in subarus "Drive" magazine.

That makes sence. You know they want you in the service station as much as they can get away with.

105k is what the maintenence brochure at my dealership says.

Also considering getting the water pump changed too, cheap if you do it at the same time.

Most manufacturers specify over 100k, which is great, but most belt breaks happen between 60k and 90k.

That's not to say your belt WILL break in that range. It's just the center of the bell curve.

i think they are designed for 100k MINIMUM with a healthy safety factor. if a belt snaps before 100k, its a design error on the part of the manufacturer.

When companies first started using them, they didn't have a service interval. "It has kevlar in it, so it'll last the life of the car, right?"

In a sense, they were right. The end of the belt's life was usually the end of the car's life. But I digress. My point is that it's usually good practice to follow the manufacturer's recommendations. But they don't always get everything right. The parts to do the timing belt job are reasonably priced and don't cost any more if you do it at 60-80k instead of 100k. It costs a lot more to repair the damage done if your belt snaps at 90k because you were waiting until 105k like the dealer said.

I waited until 105k, but like evilclown said, why not get it out of the way?

I've seen one broken belt since i've been working at a dealer, and that was a car that had ~150k and never had the belt replaced and the tensioner had also failed (WRX). 105k is fine. They DO NOT brake at 60-90k unless someone busted the timing cover and got debris in there.

I'm talking about cars in general. Most of the breaks I've seen on any make/model happen in that range. That's not to say they'll all fail by 80k.

Like I said, there's no harm in changing it before the manufacturer-recommended interval.

I'm getting mine replaced within the next week, along with the tensioner and the water pump. Went to the dealer to get the timing belt...$129.00... :eek: Mine's sitting at 108k. Although, the front and rear v-belts have been changed, I know I'm past the 105k for the timing belt. :(

$129 for just the belt? Jesus. At least you didn't get the STi belt.

The idea of a $300 "performance" timing belt still makes me chuckle. I wonder if anyone's ever actually bought one.

I got a slightly used STI one for free a long time ago... Gave it to a friend who installed it. Worked good. I'd buy one if I had a DOHC, but then again I get a deal on OEM stuffs :p
