NOTE: As the illustrations in this service information are used for different model years and/or models, some variation may occur. However, the essential information is always correct.
Removing The Coolant Pump
CAUTION: Remove the ignition key.
- Remove the expansion tank cap.
- Remove the splash guard under the engine.
- Position a container under the engine drain cock. Drain the engine coolant.
Avoid skin contact with the coolant.
- Transfer the container to the radiator draining tap. Drain off the remaining coolant.
- Close the nipples.
- Install the splashguard under the engine.
Position The Engine According To The Marking
Remove
- the cross stay between the suspension turrets.
- the servo reservoir and the expansion tank and place them on top of the engine.
WARNING: Ensure that no power steering fluid is spilled. Extremely flammable.
- the auxiliaries belt.
- the front timing belt cover.
Raise the car.
- the right front wheel.
- the nut for the cover in the right fender liner.
Install the upper timing belt cover.
Turn the crankshaft clockwise until the markings on the crankshaft and camshaft pulley correspond.
Turn the crankshaft a further 1/4 of a turn clockwise, then back counterclockwise until the markings correspond.
Remove the upper timing belt cover.
Removing The Timing Belt
- Slacken off the belt tensioner.
- Slacken off the center screw for the belt tensioner slightly.
- Hold the center screw in place. Turn the tensioner eccentric clockwise to 10 O'clock using a 6 mm Allen key.
- Unhook the timing belt.
Remove The Coolant Pump
Remove The Screws
- Tap the pump wheel with the shaft of a hammer and remove the pump
- Clean the gasket faces thoroughly.
Replace The Coolant Pump
Install:
- a new gasket.
- a new pump. Tighten the screws crosswise. Tighten to 17 Nm.
Installing The Timing Belt
Install The Belt In The Following Order:
- crankshaft
- the idler pulley
- intake camshaft pulley
- exhaust camshaft pulley
- water pump
- belt tensioner.
Tension The Timing Belt
This adjustment is carried out on a cold engine. A suitable temperature is approximately 20 degree C / 68 degree 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 above figure shows the needle position when adjusting the timing belt tensioner at different engine temperatures.
Tension The Timing Belt As Follows
- Carefully turn the crankshaft clockwise until the timing belt is tensioned.
The belt must be tensioned between the intake camshaft pulley, the idler pulley and the crankshaft.
- Hold the belt tensioner center screw secure. Turn the belt tensioner eccentric counterclockwise 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 and tighten the center screw. Tighten to 20 Nm.
Check that the indicator is in the correct position.
Check
Checking Markings:
- 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.
- also check that the indicator on the belt tensioner is within the marked area.
Reinstall
Reinstall The Removed Components:
- the upper timing belt cover.
- the front timing belt cover.
Tighten to 12 Nm.
- install the auxiliaries belt.
- reinstall the servo reservoir and the expansion tank.
Ensure that the hoses are correctly positioned.
- the engine stabilizer brace. Tighten the screws at the suspension turrets. Tighten to 50 Nm. Tighten the screw for the engine bracket. Tighten to 80 Nm.
- the cover in the fender liner.
- the wheel.
Fill the cooling system with Volvo original coolant.
Wipe clean and check the engine compartment.
Checking Work
Function Test
- Warm up the engine until the thermostat opens.
- Top up the cooling system if necessary.
Check for leaks.
