How to inspect and replace the auxiliary drive belt on Volvo S70?

Question

Accepted Answer

The auxiliary drivebelt drives power from the crankshaft pulley to alternator, steering pump and air conditioning compressor as applicable. With the engine shut off, prop the bonnet open and use it to support yourself, and then go to the crankshaft pulley end of the engine and locate the accessory drivebelt. Using an inspection light or a small electric torch, rotating the engine (if needed) with a spanner placed on the crankshaft pulley nut, check the entire length of the drivebelt for cracks, separation of the rubber and torn or tired ribs, as well as fraying and glazing, which gives the drivebelt a shiny look. Both sides of the drivebelt should be examined, it requires a twist to check the underside, fingers should be used to feel the drivebelt where it is not clearly visible. If there is any doubt as to the condition of the drivebelt, it should be renewed. Although not strictly necessary, it is easier to get into the lower belt run via the right-hand wheel arch - loosen the right-hand front wheel bolts, jack up and support the car's front on axle stands, remove the roadwheel, then remove the two plastic nuts and fold back the inner wheel arch panel to reach the crankshaft pulley. Before removing the old belt, you should note the fitted routing of the old belt around all pulleys. The correct drivebelt tension is maintained by an automatic adjuster and tensioner assembly, which is bolted to the front of the engine and has a spring-loaded idler pulley. Using a spanner on the tensioner nut to turn the tensioner to the rear of the engine compartment to relieve the tension of the belt, slip the belt off all the pulleys and then release the tensioner and remove the belt. Slide the new belt loosely over the pulleys and the tensioner wheel, making sure that the belt is properly seated but not over the top (power steering pump) pulley. Rotate the tensioner to the rear, rotate the drivebelt over the top pulley and release the tensioner and the tensioner will automatically take up adjustment. If removed, refit the inner wheel arch panel, then refit the wheel and lower the car to the ground and tighten the wheel bolts to the specified torque.
