Wondering Which Tensioner You Need?
Timing belt interval split by Engine Number
OEMVolvoParts » There is a year/engine split on timing belt intervals for the 5 cyl.
It is 7 years or 70k for 850 and up to engine -1266127 in the 98 S/V70.
(auto tensioner)
It is 10 years or 105k for engine 1266128- and on in the S/V70.
(mechanical tensioner)
This applies up to engine -3188689. Which is somewhere in mid 04/05. Then it is 10 or 120k for engine 3188690- and on.
Being that you have an 01 it is going to be 10 years or 105k.
Determine Which Tensioner You Need
Mechanical Tensioner
cn90 » Hopefully, the photo below will help make things a bit more clear (in addition to the youtube video posted previously).
– The mechanical tensioner has an eccentric design, i.e., as the adjusting tab “A” is moved, the axis of pulley rotation is changed to adjust the tension on the TB.
– The first step (once the TB is in place) is to “over-tighten” the TB a bit. This is accomplished by turning the adjusting tab CCW with the Allen key to 6 o’clock position. By doing this, the temp indicator “C” will move in opposite direction to 1 o’clock position. Now the TB is over-tightened to remove any slack during installation.
– The next step is to bring the TB tension back to normal operating condition. This is done by moving the adjusting tab “A” from 6 o’clock position —> 7 o’clock position. By doing this, the temp indicator “C” will move from 1 o’clock position —> 12 o’clock position.
– Now tighten the Center Bolt to spec.
