I need to change my timing belt and water pump, is it recommended to change the belt tensioner as well? Thanks.

Tbh if you are changing just because its recomended every 100k km, I wouldn't even do the T-belt/water pump. Inspect the belt, and then change it if needed. Or if water pump starts leaking then do that. I know people will start hating on me now, but what's the point of changing a part just because its recommended while its still good?
Is the belt tight? Then the tensioner is doing its job.

Umm because it can go at any time after that and then you'll need a new engine?

the point of changing it is because it's a major pain in the *** to replace later.

also, to the OP, definitely DO replace the tensioner. i have a friend with a WRX who was getting misfire codes constantly, and we pulled the motor on saturday to inspect and we found (and had suspected beforehand) that his tensioner wasn't working up to spec, and sure enough, it wasn't - and was created slack in the TB - you DON'T want that.

cheap insurance if you ask me.

I'd do the tensioner as well myself. Typically you can get away without doing the tensioner the first time you replace the timing belt/water pump, but if you've already done the tb/wp once, then replace the tensioner.

Ok, thanks guys. I'll pick one up just to be on the safe side. They are not that expensive and I'd hate to get into it that far I find out I have to go track one down.
