Exclamation 98 impreza 2.2 timing belt questions

Quick question here, I've got everything off right now except the TB tensioner. Looking at the guides I've seen (endwrench) their tensioner is different than the one on my car. Anyone know how mine works? Diagrams/links/drawings would help alot.

Thanks,

Ray

your tensioner should have a piston(in the center) with a hole drilled through the side of the tensioner body and the piston shaft. you can just undo the tensioner and remove. but you must compress the piston back in before reinstalling, so you can "pin it" (insert allen key of the 1.5-2.5mm size all the way through piston and both sides of the body). you'll need a bench vise or brake press to compress it probably. you should be able to route belt fine and may have to install the toothed idler pulley(drivers side bottom) last. you may need to hold pulley at an angle to find the threads in the block with idler bolt. put bolt into hole then straighten pulley as you thread bolt in! VOILA! you should have no prob., but make sure your timing is still on the marks, i had to redo mine. somehow the drivers side cam jumped a tooth while trying to insert the idler bolt. but the second time it took less than an hour to do! pm me or keep postin' if you need help!

Maybe this will help. I have a 97, and it seems that Subaru went from the type I have (and the one in Endwrench) to this new type sometime in 97. When I downloaded the service manual, it had info for both types of tensioner.

Just compress the piston slowly. I believe they suggest ~3 minutes for the full compression.
If you bang it hard and fast, you "may" blow the seal.

I highly recommend against re-using that tensioner. That new style with the integrated pulley is known for going bad and making it clack when re-used. A number of guys I know have retro'd theirs to the old pistons style because of this...
