Question about 1984 Volvo 240 Series
I need to loosen the air compressor belt in order to replace the alternator belt but not sure how to loosen the air compressor belt on 1984 Volvo 244 series?
Check to see if there is a tensioner pully that adjust the belt tightness. The tension pulley a small pulley will have two bolts on it one of them loosens and tightens the belt around the alternator and compressor USUALLY.

Applies only to B6xx4T engines:
Remove the plastic pipes between the turbocharger (TC) and charge air cooler (CAC) and between the air cleaner (ACL) and turbocharger (TC). Put them to one side. Remove the clamp from the intake manifold for the turbocharger (TC) for cylinders 1, 2 and 3. Turn the upper section of the pipe towards the firewall.
Relieve the load from the belt tensioner.
Remove the auxiliaries belt. See: Drive Belt\Service and Repair
Remove the upper timing belt cover.

Lift up the servo reservoir and place it on top of the engine.Note! Ensure that the oil does not leak from the ventilation hole in the filler cap.
Seal the hose between the expansion tank and the radiator.
Disconnect the hose at the tank.
Lift up the expansion tank and place it on top of engine.
Raise the car. Remove
the right front wheel
the plastic nuts on the cover in the fender liner. Install the upper timing belt cover.
Turn the crankshaft clockwise until the markings on the crankshaft and camshaft pulleys correspond.
Turn the crankshaft a further 1/4 turn clockwise. Then turn back counter-clockwise until the markings correspond.
Remove the upper timing belt cover.
Remove the 4 vibration damper screws. Counterhold the crankshaft central nut.

the belt cover behind the crankshaft pulley for the auxiliaries belt. Spray universal oil or similar around the rubber sleeve on the underside of the oil pump.
Remove the rubber sleeve.
Removing the timing belt
Slacken off the belt tensioner
Slacken off the center screw for the belt tensioner slightly.
Hold the center screw still.
Turn the tensioner eccentric counter-clockwise using a 6 mm Allen key.
Turn to 10 o'clock.
Unhook and remove the timing belt.Caution! Do not turn the camshafts or the crankshaft when the timing belt has been removed.
Checking the tensioner pulley and idler pulley Check bearing wear:
Spin the idler pulley and listen for noise. If replacing with a new idler pulley, tighten to 24 Nm .
Spin the tension pulley and listen for noise. When replacing, screw the tension pulley into place using the center screw.
Screw in the center screw by hand.
Ensure that the tensioner fork is centered over the cylinder block rib / bracket.
Ensure that the Allen hole on the eccentric is at "10 o'clock".
Installing the timing belt
Install the belt in the following order:
the idler pulley
tension pulley.Note! The variable valve timing unit on B6304S engines does not have a return spring. The unit is easily dislodged when reinstalling the timing belt.
Tensioning the timing belt
This adjustment is carried out on a cold engine. A suitable temperature is approximately 20°C / 68°F .
At higher temperatures (with the engine at operating temperature or a high outside temperature for example) the indicator is further to the right.
The illustration shows the position of the indicator when aligning the timing belt tensioner at different temperatures.
Carefully turn the crankshaft clockwise until the timing belt is tensioned. The belt must be in tension between the intake camshaft pulley, the idler pulley and the crankshaft.
Hold the belt tensioner center screw secure. Turn the belt tensioner eccentric clockwise until the tensioner indicator passes the marked position. Then turn the eccentric back so that the indicator reaches the marked position in the center of the window.
Hold the eccentric secure. Tighten the center screw to 25 Nm .
Check that the indicator is in the correct position.
Press the belt to check that the indicator on the tensioner moves easily.
Install the upper timing belt cover. Turn the crankshaft 2 turns. Check that the markings on the crankshaft and camshaft pulley correspond.
Check that the indicator on the belt tensioner is within the marked area.
Install the auxiliaries belt around the pulley on the crankshaft.
the rubber sleeve on the underside of the oil pump
the vibration damper.
Use new screws.
Tighten to 35 Nm .
Use the crankshaft center nut as a counterhold
the plastic nuts for the cover in the right-hand fender liner

Lower the car.
the front timing belt cover. Tension the auxiliaries belt.
the expansion tank
the hose between the expansion tank and the radiator. Remove the lock grip pliers
the servo reservoir
the upper timing belt cover.
Applies only to B6xx4T engines:
Twist the intake pipe for the turbocharger for cylinders 1, 2 and 3 into position.
Tighten the clamp.
Install the plastic hoses between the turbocharger (TC) and the charge air cooler and between the air cleaner (ACL) and the turbocharger (TC). Tighten the hose clamps.
the engine stabilizer brace. Tighten to 50 Nm
the screw holding the engine stabilizer brace to the bracket on the engine. Tighten to 80 Nm .
Check and top up if required
the servo fluid level. Test drive the engine.

You'll need a torque wrecn and a degree tools (most auto parts stores sell them). Torque sequence is 15lbs, then 37lbs then 130 degrees.

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

To adjust the tension of the alternator drive belt on all models, loosen the pivot and mounting bolts on the alternator. Using a wooden hammer handle, a broomstick or your hand, move the alternator one way or the other until the proper tension is achieved.
WARNING Do not use a screwdriver or any other metal device (such as a prybar) as a lever.
Tighten the mounting bolts securely. If a new belt has been installed, recheck the tension after about 200 miles (480 km) of driving.
Air Conditioning Compressor
A/C compressor belt tension can be adjusted by turning the tension adjusting bolt which is located on the compressor tensioner bracket. Turn the bolt clockwise to tighten the belt and counterclockwise to loosen it.
See Figures 12
To adjust the tension of the air pump drive belt, loosen the adjusting lever bolt and the pivot bolt. Move the pump in or out until the desired tension is felt.
The tension should be checked between the air pump and the crankshaft pulley on cars without air conditioning. On cars with A/C, the tension should be checked between the A/C compressor and the crankshaft pulley.

Power Steering Pump
Tension on the power steering belt is adjusted by means of an idler pulley. Turn the adjusting bolt on the idler pulley until the desired tension is felt and then retighten the lockbolt.
