How do i find timing marks for 2002 volvo v70 xc?

Removal & Installation

1.5L, 1.6L (VIN 5) & 1.8L Engines

1. Before servicing the vehicle, refer to the Precautions Section.
2. Disconnect the negative battery cable.
3. Remove the accessory drive belts.
4. Remove the alternator.
5. Remove the water pump and crankshaft pulleys.
6. Remove the timing belt guide plate.
7. Remove the upper and lower timing belt covers.
8. Position the crankshaft so that the timing mark is aligned with the timing mark on the engine.
9. Verify that the I and E mark on the camshaft pulley align with the mark on the cylinder head.
   NOTE
   Do not move the crankshaft or camshaft once the timing marks have been correctly positioned.
10. If the timing belt is to be reused, mark the direction of rotation on the timing belt.
11. Remove the timing belt tensioner pulley.
12. Remove the timing belt.

To install:

1. Install the timing belt tensioner pulley, move the tensioner to its furthest point and tighten the lockbolt.
2. Install the timing belt onto the pulleys, as follows, crankshaft pulley first, then the idler pulley, exhaust camshaft pulley, intake camshaft pulley, and the tensioner pulley.
3. Loosen the tensioner pulley and allow the tensioner spring to apply tension on the belt, then tighten the lockbolt to 28-38 ft. lbs. (38-51 Nm).
4. Rotate the crankshaft clockwise 2 turns and be sure all marks are still correctly aligned.
5. Install the remaining components in the revere order of the removal noting the following torque specifications:
   
   Crankshaft pulley: 9-13 ft. lbs. (12-17 Nm) Water pump pulley: 9-13 ft. lbs. (12-17 Nm)
6. Connect the negative battery cable.

REMOVAL
1. Disconnect negative battery cable.
2. Loosen power steering lock bolts and nuts accordingly and remove tension from power steering (P/S) and/or air conditioning (A/C) compressor drive belt.
3. Remove P/S and/or A/C drive belt.
4. Loosen generator mounting bolts and adjusting bolt.
5. Remove generator bolts.
6. Remove water pump pulley.
7. Remove crankshaft pulley.
8. Remove upper and lower timing belt covers.
9. Turn crankshaft so that timing mark on timing belt pulley is aligned with timing mark on engine.
10. Check that "I" mark on intake camshaft pulley is aligned with mark on seal plate and "E" mark on exhaust camshaft pulley is aligned with mark on seal plate.
Do not move camshaft or crankshaft once timing marks have been correctly positioned.
11. Loosen tensioner pulley lock bolt.
12. Protect timing belt with a rag.
13. Remove tensioner pulley.
14. Remove timing belt. Mark the direction of timing belt rotation (on the timing belt) for proper reinstallation.

INSTALLATION
1. Install tensioner pulley. Replace tensioner spring whenever timing belt is replaced.
2. Pull tensioner pulley to its furthest point and tighten lock bolt.
3. Check that timing mark on timing belt pulley is aligned with timing mark on engine.
4. Check that "I" mark on intake camshaft pulley is aligned with mark on seal plate and "E" mark on exhaust camshaft pulley is aligned with mark on seal plate.
If existing timing belt is being reused, install belt in proper rotation direction marked prior to removal.
5. Install timing belt onto timing belt pulley first, then idler pulley, exhaust camshaft pulley, intake camshaft pulley, and tensioner pulley in that order.
6. Check that there is no looseness in belt between idler pulley and exhaust camshaft pulley or between intake and exhaust camshaft pulleys.
7. Loosen tensioner pulley lock bolt and allow tensioner spring to apply tension to timing belt.
Do not add additional tension.
8. Tighten tensioner pulley lock bolt to specified torque.
Tightening torque:28~38 lb-ft (38~51 N·m, 3.9~5.2 kg-m)
9. Rotate crankshaft two full revolutions (clockwise only) and align timing mark on timing belt pulley with timing mark on engine block.
10. Check that "I" mark on intake camshaft pulley and "E" mark on exhaust camshaft pulley are aligned with marks on seal plate.
11. If they are not aligned, remove timing belt and start process from tensioner installation.
12. Measure timing belt deflection by applying moderate pressure midway between camshaft pulleys. If deflection is not correct, repeat from tensioner installation.
Deflection pressure:22 Ib. (98 N, 10 kg)Deflection:0.39~0.50 in. (11~13 mm)
13. Install lower and upper timing belt covers in that order.
Tightening torque:5.8~8.0 Ib-ft (7.9~10.7 N·m, 0.8~1.1 kg-m)
14. Install timing belt guide plate and crankshaft pulley.
Tightening torque:9.0~12.6 lb-ft (12.3~17.2 N·m, 1.3~1.8 kg-m)
15. Install water pump pulley.
Tightening torque:9.0~12.6 lb-ft (12.3~17.2 N·m, 1.3~1.8 kg-m)
16. Install generator belt and adjust the tension.
17. Install P/S and/or A/C drive belt and adjust the tension.
18. Connect negative battery cable.

INSPECTION
Never forcefully twist, turn inside out or bend timing belt. Do not allow oil or grease to come in contact with timing belt.
1. Replace timing belt if it is contaminated with oil or grease.
2. Check timing belt for uneven wear, fraying, peeling, cracking and hardening. Replace timing belt as necessary.
3. Bend timing belt into a "U" shape as shown in figure. Distance "A" must be at least 1.0 in (25 mm).
4. Inspect both idler pulley and tensioner pulley for uneven wear and smooth bearing operation.
5. Inspect camshaft pulleys and timing belt pulley for broken teeth or damage.
Replace any component that shows damage, excessive wear, or that appears prone to a possible failure.

CODE P1171 SYSTEM TOO LEAN BANK 1 PART LOAD. POSSIBLE CAUSE - INTAKE/EXHAUST LEAK , FAULTY MAF SENSOR , FAULTY MAP SENSOR OR FUEL PRESSURE TOO LOW DUE TO STOPPED UP FUEL FILTER.WEAK FUEL PUMP.

The most common problem is either the blower motor or the speed control resistor. Both items can be accessed by removing the glove box and panel below it.

1. Disconnect battery negative cable.
2. Remove power steering and air conditioning compressor drive belt by loosening power steering fasteners.
3. Remove generator bolts and generator belt.
4. Remove water pump pulley.
5. Remove crankshaft pulley and timing belt guide plate.
6. Remove upper/lower timing belt covers.
7. Turn crankshaft clockwise until "I" mark on intake camshaft pulley and "E" mark on exhaust camshaft pulley align with marks on cylinder head cover.

if it is available the sensor can be replaced if not you will need a transmission

You will have to reset the timing. there should be marks on the sprokets and the crank gear, just line up all the marks at the same time, then replace the belt and turn it over by hand a couple of times to be sure they have stayed in adjustment. Don't crank it over with it out of time because you can do major internal engine damage

If your car has the xenon headlights, it might be a faulty xenon ballast/regulator module. You car has daytime running lights so they are on at a low power setting all the time.

theirs a cut out switch that should be under bonnet with a red rubber cover on it ,reset this by pushing it down
