Timing belt life

[l.lichtman]

My 1999 Subie Outback, 2500, calls for timing belt replacement after
105,000 miles. My friend has a 1998, and his belts had to be changed
at 60,000, which he did. Now he is coming up on 110,000 miles, and we
are wondering whether he is due for another timing belt. Would a new
timing belt, installed after the newer cars were rated for 105k be of
improved quality and life expectancy, or is there something about his
older engine that imposes the shorter belt life. He is getting vague
and conflicting answers from different sources.

Your friend's car may have a different engine. My '96 Legacy Outback
has the 2.5 liter engine and timing belt change is specified for 105k
miles, but the change interval for the 2.2 liter engine is 60k miles.

In any case, follow the change interval specified for the engine IN
QUESTION for each timing belt change -- first and subsequent.

I think very 60,000 miles is it but, to be sure go to the source at
www.subaru.com and ask the technical question.

Timing belt life for my 2000 Legacy which has a 2500cc engine like yours
(but made in japan), is 100.000 km which are 62500 Miles.

The owner's manual would probably have this information available in it as
well.

I changed mine at 100,000 miles and the mechanic said it still had a lot of
life left in it.

It probably did, but my mechanic showed me a couple of broken belts
that also looked like they still had a lot of life left in them *except
at the break.* These belts evidently don't deteriorate and become
ragged before they fail.

Sounds like he showed you the last one I had fail! Looked great, except
it was broken. Hmmmm...

As to your original question about the differences between the years'
recommendations, unless it's certain the same belt is being used (OEM
numbers match, NOT relying on aftermarket specs where it's highly likely
the same belt will be spec'ed regardless of what the factory used), I'd
stick to the book's recommendation for mileage.

Is there any definitive list as to what years and models are (or are not)
interference engines?

 

[Edward Hayes]

Subaru stated that ALL 2.5L engines ARE interference engines.
