bgambino Posted July 13, 2015 Share Posted July 13, 2015 Okay...just a random question running thru my mind... How far past the 105k service mark have you gone with a timing belt? Personally, I do not like tempting fate with an interference engine so, fear rules me...I try to be religious about it Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted July 13, 2015 Share Posted July 13, 2015 On am interference engine I don't usually let them get anywhere close to 105k, the biggest cause of belt failure is one of the idlers chucking a bearing. I try to do them in the 75-80k range or less, and usually I find an idler with more play than it should have. When I did my mom's 04 outback's belt last year it had about 60k on the job according to paperwork from the PO and it was really close to loosing the bearing in the cogged idler by the water pump.

raleigh800 Posted July 13, 2015 Share Posted July 13, 2015 130k+ and this is the result. Last 2 owners never replaced the Tbelt. It was on my to do list, and is now a #1 priority. Quote Link to comment Share on other sites More sharing options...
gbhrps Posted July 15, 2015 Share Posted July 15, 2015 gentlemen, Age and heat have as much to do with timing belt failure as mileage does. So if the car is ten years or older and only has 60 000 miles on it, say, it would well be adviseable to pull the timing belt cover, rotate the engine, and check the belt out. My 25 year old 300zx has only 48 000 miles on it at present. Six years ago I pulled the timing cover, and after inspection, I changed it. Glad I did. 2 Quote Link to comment Share on other sites More sharing options...
subnz Posted July 15, 2015 Share Posted July 15, 2015 Agree very risky especially on interference motors when Subaru Japan recommend changing T belts at 60K miles (100K km) (48 months) {owners manual} Quote Link to comment Share on other sites More sharing options...
bratman2 Posted July 16, 2015 Share Posted July 16, 2015 I have done three older ones at 80k to very low 80k. All looked like they had many 10's of thousands of miles to go. My wife's 2011 XT has low 80k now. I am waiting on it until the 105k recommended. But not any further. Quote Link to comment Share on other sites More sharing options...
ThosL Posted July 16, 2015 Share Posted July 16, 2015 I am probably way over that; when F and S did the water pump replacement, the timing belt was OK and we decided not to replace it. Well over 100K on a 2.2 with no replacement. Quote Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted July 17, 2015 Share Posted July 17, 2015 My friend's 04 RS had 156k on his OE belt... (it said mitsuboshi and the cover bolts were untouchced/rusted in place). Quote Link to comment Share on other sites More sharing options...
turodoggy Posted July 20, 2015 Share Posted July 20, 2015 This isn't on a subaru, but on an older Nissan Pathfinder (VG30E) we have, the timing belt is suppose to be changed at 60,000 miles. We are probably at least at 120,000, probably more, right now. Yes it is an interference engine, although it can be changed to non interference. The Pathfinder isn't driven anymore, just started occasionally, so I'm not in a rush to change it anymore. I would give more exact mileage but the speedometer stopped working at some point, and we put a lot more miles on it. It has at least 250,000 if not 300,000. Great engine by the way, it runs smoother than almost any other car i've seen. It starts right up ever time, even after sitting for a year, without the gas being changed, and still idles perfectly. On the other hand, on my Subaru, with the EJ25D, I will replace as instructed. Already did it once with the head gasket, hoping not to it again with the head gasket. Its not hard to change anyway, so I would recommend changing it when recommend. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted July 20, 2015 Share Posted July 20, 2015 I'm sure they've gone 200,000 miles before. plenty of people don't do anything but oil changes or until symptoms present. 1 Quote Link to comment Share on other sites More sharing options...
subyrally Posted July 24, 2015 Share Posted July 24, 2015 with my wrx, i think i went 115k before i was able to get the belt service. get the work done, they said everthing still looked good, but its probably still for the best that it was changed out anyway. i do trust the dealership that i go to, the service department people are actual subaru people, the service write knows her subarus an even drives one herself.

Bushwick Posted July 26, 2015 Share Posted July 26, 2015 It's not something to even consider. Engines going over 110k miles + are in all actuality probably chain driven. If you drive 100k miles in a year on strictly highway cruising, it *might* be possible to go longer, but NOT worth it. My mom gave me her old 91' Geo Storm GSi around 2000 and it had either mid 50's or 63k, I can't remember. She never beat on it or anything. I was clueless about belts back then and was going into 2nd gear after pulling away from a stop and it quietly stalled. Thankfully it was non-interference and super-easy to work on after getting towed home. Rubber belts typically will NOT last after a certain point. It's not an "If" situation either. It's a "when".
