Inspect and replace pulleys
Volvo V70 models utilize one multi-rib engine drive belt.
Figure 1

Volvo V70 models utilize one multi-rib engine drive belt. The belt may be referred to as a serpentine belt because it snakes around the engine accessories. This diagram shows two of the common belt routings. The main difference being an additional idler pulley. I suggest making your own diagram before removing your drive belt.

With your engine cold and turned OFF, inspect your drive belts for wear.
Figure 2

With your engine cold and turned OFF, inspect your drive belts for wear. The belts should be free from cracks (green arrow), fraying, glazing and missing chunks. Replace your belt if any of the previously mentioned issues are present or every 4 years. In this article, I'll go over the steps involved with replacing the drive belts on the Volvo V70 models. Be sure to work with a cool engine and remove the key from the ignition.

Working at the right side of the engine compartment, pull the E-box cooling vent hose off and place out of the way.

Then pull the power steering hose out of the mounting bracket (green arrow) and place aside.

Then pull the power steering hose out of the mounting bracket (green arrow) and place aside.

Unclip and slightly lift coolant and power steering reservoirs.
Figure 5

Unclip and slightly lift coolant and power steering reservoirs. Raise them just enough to gain access to electrical connector for coolant level sensor.

Then, disconnect coolant level sensor electrical connector by pressing release tab (green arrow) and pulling apart.

Then, disconnect coolant level sensor electrical connector by pressing release tab (green arrow) and pulling apart.

Place coolant and power steering reservoirs on engine out of your way.
Figure 7

Place coolant and power steering reservoirs on engine out of your way. Before removing drive belts, mark direction of rotation (if reusing belts) and note installation position.

Next, using a 14mm wrench, rotate belt tensioner clockwise to release belt tension.
Figure 8

Next, using a 14mm wrench, rotate belt tensioner clockwise to release belt tension. With tension released, pull belt off tensioner pulley, then remove belt from remaining pulleys and remove from engine. Raise and support front of vehicle. See our tech article on jacking vehicle.

Remove right front wheel.
Figure 9

Remove right front wheel. Then remove 10mm fender liner fastener (green arrow) and fold fender liner open to access crankshaft pulley. With belts removed, inspect pulleys for lateral play or binding. To install accessory drive belt, begin by wrapping belt around crankshaft pulley, then wrap it under and around A/C compressor pulley and alternator (the order will vary depending on your engine). Then run belt under tensioner and release tension, wrap belt around power steering pulley and release tensioner. Once the belt is properly installed on all accessories, check that it is properly aligned and installed in all pulley grooves correctly. Be careful not to force belt onto pulleys, damage may occur. Start engine and allow to run for less than 5 seconds, shut engine OFF and recheck belt installation. Reinstall fender liner fastener and coolant and power steering reservoirs once complete. Then install E-box cooling vent.
