I have 1992 Volvo 940 turbo 4cyl . I need advice on how to change my alternator belt

Underneath the alternator facing forward is a 13 mm nut which locks the alternator in place, slacken this off and the two nuts/bolts where the alternator pivots.From the left side of the car there is a 10 mm bolt which is the tensioner, slacken this untill the alternator can be moved towards the engine sufficiently to remove the belt .Reverse this procedure to replace the belt. (depending on drives to other items you may have to remove their belts as well)

I need to change the timing belt on my 93 940 volvo

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

Need help wit belt 1194 940 volvo!

It is possible you are looking at the page for the 1994 960 and not the 940. The 960 had one (serpentine) belt. Your 940 has three. Hopefully chiltons has the repair order for the 940s as well.

I know it's not alot, but I hope it helps

'88 Volvo 740GLE won't get past 30 mph

Horrible squeal. If my 740 made a horrible squeal I would be upset also. These ideas - timing belt has somehow slipped out of time. Easy check. One of the other belts are slowing the engine any of them can squeal: The alternator belt The power steering belt The fan belt. Does the noise occur only when driving? Does the engine sound normal when revving in neutral? Does turning on the lights or a/c affect the noise? Does the power steering work when car is standing? Is the squeal heard when turning the wheels. A logical diagnosis will identify and eliminate these easy to fix problems.

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.

I replaced mine on the same car.  I borrowed the NAPA timing belt book to get the timing marks.  There are three that need to be aligned.  I would suggest going to NAPA to buy the belt ($25) and while there, ask to see that book so you can write down the timing marks.  The mark on the crank shaft gear is on the inside of the gear, while the cam gear is on the outside of the gear.  Or, you could just buy the book.  It's still a lot cheaper than paying someone to replace the belt.
