When a garage replaces the cambelt, is it normal practice to replace the tensioner also?
Can anyone direct me to a link where someone on Scoobynet has done the cambelt themselves to see what is involved.
Many thanks,
Gus.

 

It shouldn't be necessary to replace the tensioner as a matter of course. It can be successfully re-used provided that

a) It's not knackered
b) It's reset correctly.

As far as replacement is concerned, it's basically a case of removing the ancillary belt(s) and crank pulley, removing the belt cover, aligning the crank and timing pulleys, removing idler and tensioner, resetting tensioner, fitting new belt and then reversing the process.

Taking the radiator out beforehand gives more space to work, but isn't essential.

 

Thanks for the info Greasemonkey. The person I spoke to at a local Subaru dealership didn't seem to know if the tensioner would be replaced at the same time and another dealership didn't return my call, that's why I asked the question. Is it the case you need a special tool to reset the tensioner?
Cheers,
Gus.

 

Depends which type you have. The version of the tensioner used on the MY99 and onwards cars has a reputation for being easier to kill than the older one.

You should really use a hydraulic press to reset it, but you can get away fine without one if you're careful. The tensioner must be compressed vertically - you can use a hand vice, turning it slowly and carefully, taking at least three minutes. Once it's down, pop a pin or allen key in the hole to lock it.

 

Thanks again Greasemonkey. Looks like I have the more fragile one as its a MY2000.
Cheers,
Gus.
