I need to replace the alternator belt on a 1994 Volvo 940T, but can't get the A/C belt off so I can remove the alternator belt. Apparently there's an adjustment bolt on the compressor that I can't see.

No you don't but you may need to remove the radiator if you have big hands like me to get all the space needed

Disconnect the battery. Remove the serpentine belt. Disconnect and remove the power steering pump. Unbolt the alternator and remove. Replace the alternator and reassemble.

If the speedometer and odometer are not working the problem is usually lack of signal from the transmission speed sensor.
But if the cruise control works and the speedometer does not, my guess would be a problem inside the cluster.

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)

Hmm, well that would really depend on which belt you got. I would start at the crank, go counter clock wise to the a/c pulley, up to the alternator, then to the idler, next power steering, and back to the crank under the tensioner, there was a longer belt introduced later, and IF you have that belt, same counter clockwise rotation, start at crank, go to a/c compressor, Idler pulley, alternator, power steering, then back to the crank, under the tensioner

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

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.

loosen the bolt that is holding the adjuster of the alternator. loosen the belt by pulling it and the alternator would slide in. remove and replace the belt.

do the reverse on installation.

remember to tighten all bolts of the adjuster and alternator after tightening the belt.

tnx 4 using fixya,
