Default Anyone have any problems waiting the 105k for timing belt change?

I now have 86k on my car and saw in my book that the timing belt doesn't have to be changed till 105k. That to me seems like a lot to me. I have worked on cars all my life and have never seen an interval that high. Anyone have one break before 105k? I'll wait that long if I can(Lazy if you know what I mean) But if they don't make it that long sometimes I want to do it at 90k or so.

Thanks for the input

I did mine at something like 115,xxx miles and the belt looked like it could have gone another 50,000. The recommended 105k interval should be fine.

I wouldn't go more than 105k miles. The tensioners on these cars seem to go bad, plus its better to have a new water pump/thermostat installed at the same time. I did mine at 95k miles, with a new water pump, tensioner, idler pullies. The belt istself looked brand new.

Is that what they recommend for the USDM STI too? JDM version is 100K Kms = 62,000 miles

And to mirror everyone else, I just did mine this past weekend at ~110,000mi. Belt was a little worn from a bad idler/pulley but otherwise looked great. Replaced the thermostat while I was in there along with 3/4 of those expensive ass idlers/pullies and the tensioner.

105k (or more) is VERY common on vehicles made since 2000. Ironically it seems domestics are kicking imports around in this area, some imports still require a 60k change interval. Read around here, there are VERY few threads of a timing belt or water pump actually failing. It is probably more the tensioner than anything else that is prone to fail.

I did the waterpump, tensioner, and thermostat also.

Mine was done at 110k, by my local dealership w/ tensioner and idlers. They steathoscoped the water pump (and idler bearings) as that was a concern for me and they said the water pump was fine but the idlers need replacing, the tensioner was a required replace for the T-belt maintainance.

Then the AC idler siezed 6-9 months after the timing belt was replaced.

Cool. Thanks guys. I'll wait and do the water pump and idle pully at the same time.

I think mine went 152k until it got changed (not original owner so don't know for sure). The belt was pretty worn along with pretty much everything else minus the tensioners.

I don't understand why everyone brings the water pump into question. I've owned 3 Subaru's, all with over 200k miles, and they all have/had the original water pump.

Tensioners and idlers are a different story though. I just had an idler sieze and blow up on me last week. I got lucky though, eventhough the cam sprocket jumped 3 teeth I didn't bend any valves.

I did mine at 109K on a stock 2001 Forester and the T-belt was in great shape. It looked like it had plenty of life left in it. The accessory belts, on the other hand, were ready to be replaced. The cogged idler was running a little rough, so I replaced that, but the other idlers and tensioner felt perfectly smooth, so I left them on. I did replace the water pump as a precaution - though it too seemed in great shape. Absolutely no leakage from the shaft seals, so I left them in place.

not really, even if you look at the belt they can look surprisingly good. I would say probably not, people usually don't do major maintenance and trade it off, most likely the upcoming cost of the timing belt was possibly one of the reasons they got rid of it.

In regard to the water pump, I don't think the concern is so much subaru specfic as it used to be a general rule with T-belt replacement on dual overhead cam engines. I had a previous car that was SOHC and did not have to remove the T-belt to replace it.

Did it with a few extra hands for support. Surprisingly easy. Get a 10mm allen key or socket adaptor to hold the driver's side cams in place.

My local dealer quoted me $425 parts + labor for the job (as opposed to $1100+ elsewhere), 2-3 hours max, and they said I can bring in the accessory belts if I would like (Subaru OEM timing belt + components). Not bad, that's very cheap service per 100K miles.
