My father is working on a 1994 Volvo 940 station wagon(2.3L engine, single overhead cam) and when he started it, the timing belt jumped and now he has to get it back in time. There are no manuals for this particular model, so he needs to know how to do this. Can you help?
1996 Volvo Sta Wagon 850 model needs timing belt anyone know cost?
I hope you've solved the problem by now, but there are alignment marks on the crank shaft (top pulley), idler (lower side), and cam shaft (smaller, bottom pulley) which should be aligned with stationary marks on the timing belt rear cover.
The belt has marks that align with the aforementioned marks (lines). The double marks on the belt align with the camshaft marks and the single marks with the others.
Loosen the tensioner clamp (nut) to allow the spring loaded tensioner to press on the belt and retighten the nut.
Rotate the crank shaft (clockwise, probably two revolutions) and make sure the pulley marks realign to the marks on the cover (they don't have to realign with the marks on the belt).
Rotate the crank shaft a full revolution once the belt is on and check that alignment is preserved.
Periodically loosen and retension the tensioner nut (access through a hole in the cover) to ensure that tension is maintained as the belt relaxes.
