2001 volvo v70 2.4 non turbo timing belt allignment marks
It is rather easy to see the top two cam allignment marks on the cam cover however I cannot see the lower crank mark. The gear hash marks on two seperate gears but what do these line up with? I replaced my belt and the car is running nicely however my fuel economy has gone down, I'm thinking I may be off a notch. Is it possible to be off and have the car still run smoothly?

Re: 2001 volvo v70 2.4 non turbo timing belt allignment...
Not sure if it is possible to have it run smoothly by being off a tooth.
The hash marks on the cam pulleys line up with the timing belt cover that goes over those pulleys. Should be two notches in the cover.
As for the lower marks...those aren't really visible till the lower aux. belt pulley is removed. Then you'll have a clear view of the line up marks. One on the inside and one on the outter area of the pulley itself.
When you put the t-belt on...it is a good idea to replace the tensioner as well.
Also when you have the new belt on...adjust the tensioner so that the handle looking thing is centered between the two notches that hold the tensioner in place to the block.
After putting all that together, its a good idea to rotate the timing belt two to four rotations till the marks all line up again. That will let you know if you are hitting the valves or not.

There is a very good chance you bent some valves when the belt broke. If it's a 1.8 turbo then definitely, 2.0 you have a small chance that it is ok. The marks are easy to see, one notch on the cam and one on the crank, the crank lines up to the line on the plastic cover that covers the t belt, the cam lines up to the plastic backing piece that is bolted down with the valve cover. Best of luck.
You will probably have to take your timing belt off, allign the marks, then put your belt back on. Had the same problem. That's what I had to do. They have to be alligned. Check your book though. I think all has to be at 12 o'clock but I am not 100% sure.
I refer to a question asked on 15 April re timing marks but I am looking for info on the same marks on a VolvoS40 2litre Non Turbo
1997. Does this kit you talk about apply to this as well. If so where can I get it. I live in cape town south africa
remove auxilary belt remove one bolt from timing belt cover remove cover turn engine to tdc using socket on crank nut check cam pulleys lined mark with white paint or tipex remove 4 bolts on crank pulley then centre pulley nut use impact gun prise of pulley check all marks still lined up buy or borrow universal cam sproket lock tool this is important to stop cams moving when belt of release tensioer remove belt chek water pump for leaks and wear fit new tensioner then new belt keep tight on non tension side feed over sprokets tension belt to align pointer on tensioner turn engin 2 times re check timing marks fit all parts removed
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.
REMOVE BELTS FROM FRONT OF ENGINE, REMOVE COVER ON TIMING BELT, REMOVE TIMING BELT AFTER MARKING THE WHEELS WITH THE ARROWS ON THE CAM SHAFT WHEELS. WATER PUMP IS LOCATED AT BOTTOM HOSE HOUSING IT IS A COMPLETE UNIT INCLUDING CASTING. EASY TO FIT REPLACE ALL PART AND MAKE SURE TIMMING BELT IS NOT OUT OF SEQUENCE GOOD LUCK.
