Timing Belt service, Anything Else?
Hi All,
I've got my 125k service coming up and wanted to find out if there is anything else should be done whilst the timing belt is replaced? I've read that the its a good idea to replace the water pump, maybe cam gears. Is there anything else?
Cheers Guys

Ok so the point of this thread was to establish what else could be done whilst the timing belt is being replaced. As it is fairly labour intensive just to get to the timing belt, it is probably a good idea to replace other components at the same time, as A)this should not affect the cost of labour and B) as a preventative maintenance approach for the longevity of the engine.
I’ll list what options are available and what costs are involved. My service was done by a Subaru Stealership, so costs will be on the expensive side. You shouldn't have to pay more than what I have paid.
So the cost of the 125k service is a little under $1000 but Caution has been quoted just shy of $700 for his service.
The general consensus seems to be that at the very least the water pump and thermostat should be replaced. Aftermarket high flow water pumps can be considered,(apparently Phat has one that has a better impeller design?)but from my understanding OEM does the job just fine. Cost of OEM ~$150. Rising Sun has the water pump for $110 no mention of thermostat.
Next I'd consider replacing the hydraulic tensioner and idler pulleys. Some info here and here. All this comes in a kit. Cost for the kit $425 from rising sun, although Bumpty got it for $400. The kit is missing a small idler puller which may only apply to turbo models(its listed as idler pulley turbo on my invoice) and has to be purchased additionally about $70-$80 Part no. 13073AA200
Gears and seals. These can be considered as well although the gears are not a wear type component and don't really need replacing. As for the seals, apparently Subaru have used a Viton over rubber compound and are not prone to leaks, they may last up to 300k.
I'll leave this here for now, it's getting late. There's certainly more to consider, adjustable cams, lightweight pulley, OCV's, but I think the above is probably the most important for now. I know I've missed stuff so if anyone else has anything to add let me know and I'll add it.
