Timing Belt Idler pulley and Tensioner
Hi,
Car: Volvo s80 1999 2.9 Non Turbo 110000 Miles on it.
Got my change timing belt and cam shaft seals on 100000 Miles.
But did not change Idler Pulley and Tensioner.
My Question is, If I do myself do I have to take off the belt again in order to put pulley and tensioner.
1:Can I just take the idler pulley nut off and put the new pulley in?
2:Same Question for tensioner.
Will appreciate correct procedure.

Thanks,
Since this car has hydraulic tensioner, I meant tensioner idler pulley. I heard these hydraulic tensioner can be reusable and does not go bad. So I am changing the Tensioner Idler pully and timing belt roller/idler.
Please correct me.
Secondly I am worried about marks to be aligned, do I have to check the marks? Because I am not taking the belt off. Kindly advise.

The marks are checked while the engine is stopped. Everything must be in the proper place when you reassemble otherwise you risk the engine not running, or worse, damaging itself by having pistons and valves contact each other due to the timing being off. The marks should match both before you begin the release of the tensioner and after reassembly.
