I am replacing the timing belt on a 93 volvo 940 with 4 cly single overhesd cam no tubo. Where does the cam's timing mark line up? I don not have a repair manual for this.

you dont will have to be taken to a shop,
there they have the right tools and knollage to handle that,

most engine are interferance engines-
if engine is turned over with belt off the all valves will be bent- resulting in costly repair-
so disconnect the battery before it is towed.

This is definitely not ajob for the beginner. The cams will need to be locked down with a special tool. If they move at all, your timing will be way out and you will have some serious trouble on your hands. Either take it to a dealer or a shop that works on Volvo. Most shops will turn down a timing belt job on a Volvo. When replacing the timing belt, you also need to replace the water pump, front crank seal, both cam seals, and im not 100% sure but I think the 940 has a balance shaft belt that will need to be replaced. I may be wrong about the balance shaft belt. The total cost of this job will be from 800.00 to 950.00 depending on the shop

Your public library will have a manual covering your mechanical repair. Moreover, they have the automotive shops online software called AllData. It is the best auto technician database available today. You can print out specific troubleshooting procedures, diagrams, step-by-step istructions, and soforth. The typical person cannot afford to pay for this service, just automotive dealerships, etc... that is why the public library made it available to everyone and for free to view and print out material. This should Fixya! Good Luck!

Please stop posting useless responses like Bob above. This helps NO ONE!

The same thing happened to my 94 volvo 960 the engine belt was having the same problem, i changed it the belt, it was fine for a few miles after that it just died, does not fire, not sure if it is getting fuel, but the mechanic says the timing belt went off. you may have to check the crank sensor on yours.

TAKE FRONT COVER OFF(AFTER REMOVING FAN, BELT S, PULLEY AND FAN SHROUD).THEN REMOVE CRANK SHAFT PULLEY. WHEN COVER IS REMOVED YOU'LL SEE 3 SPROKETS, SUGGEST TO BRING CRANK TO TOP DEAD CENTER UNTIL YOU SEE ALL 3 MARKS FOR THE TIMING BELT. REMOVE BELT/INSTALL NEW AND REVERSE PROCEDURE.

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.
