  Q: What is the process of power transmission by the auxiliary drive belt and How tot be replaced for petrol engines on Volvo S80?

  A:

  The drive belt is used to transmit power from the crankshaft pulley to the alternator, steering pump, and air conditioning compressor as applicable. Access to the lower belt run is easier via the right-hand wheel arch; loosen the right-hand front wheel bolts and jack up and support the front of the car on axle stands, remove the roadwheel, remove the two plastic nuts, remove the metal plate, and fold forwards the inner wheel arch panel to reach the crankshaft pulley. Before stripping off the old belt, record where it is fitted around all of the pulleys. The proper drive belt tension is maintained through an automatic adjuster tensioner assembly which is bolted at the front of the engine with a spring-loaded idler pulley. Use a screwdriver to prise off the plastic cap if fitted, and then use a spanner on the tensioner nut to rotate the tensioner to the back of the engine compartment, which relieves the belt tension. Slip the belt off all the pulleys, loosen the tensioner, and remove the belt. Check the tensioner and idler pulleys for any roughness or damage and renew if necessary. Fit the new belt loosely over the pulleys and the tensioner wheel, put the belt in place but leave it off the top power steering pump pulley. Rotate the tensioner to the rear and work the drive belt over the top pulley and release the tensioner; the tensioner will automatically take up the adjustment. If it was removed, refit the inner wheel arch panel and refit the wheel, and lower the car to the ground, tightening the wheel bolts to the given torque.

  Q: What is the process of power transmission by the auxiliary drive belt and How tot be replaced for diesel engines on Volvo S80?

  A:

  The drive belt carries power from the crankshaft pulley to the alternator, steering pump and air conditioning compressor as appropriate. Access to the lower belt run is easier from the right hand wheel arch, loosen the right hand front wheel bolts, jack up and support the front of the car on axle stands, remove the roadwheel, remove the two plastic nuts, remove the metal plate and fold forward the inner wheel arch panel to access the crankshaft pulley. Before removing the old belt, note where it was fitted around all pulleys. The proper drive belt tension is maintained by an automatic adjuster and tensioner assembly that is bolted to the front of the engine and contains a spring-loaded idler pulley. For D5244 T to T3 engines use a screwdriver to prise off the plastic cap if fitted and turn the tensioner clockwise with a spanner to loosen the tension on the belt and slip the belt from all the pulleys, release the tensioner and remove the belt. For D5244 T4 to T7 engines, unclip the power steering hose from the bracket, undo the 2 Torx bolts and remove the drive belt cover. Using Volvo tool No 999 7109 or a T60 Torx bit and spanner, to turn the tensioner clockwise to relieve the tension on the belt to slip the belt off all the pulleys, release the tensioner and remove the belt. For all engines check the tensioner and idler pulleys for any roughness or damage and renew where necessary. Consequently, fit the new belt loosely over the pulleys and the tensioner wheel while making sure it is in place but not over the top (power steering pump) pulley. Rotate the tensioner clockwise and work the drive belt over the top pulley and release the tensioner which will automatically take up the adjustment. If removed, reinstall the inner wheel arch panel, before reinstalling the wheel and lowering the car to the ground, by tightening the wheel bolts to the specified torque.
