TIMING BELT

2001 Hyundai Accent

2001 Hyundai Accent 4 cyl Front Wheel Drive Automatic 120000 miles

my wife was driving down the interstate and the timing belt busted. It is the 1.6 liter engine. We had the car towed back to our house, where a buddy and I proceeded to attempt to get into the area where the timing belt is located. The top sprocket is where the timing marks are supposed to be. The bottom sprocket is not. How do I turn it so I can get the timing belt on their without worries about messing everything else up in the engine.

Your vehicle has an interference engine. In the vent that t he timing belt breaks, you will have a few bent valve and maybe even pistons. The entire timing belt cover (top, middle, and bottom) will have to come out to replace the belt. You cannot just line up the camshaft (top sprocket) without aligning the crank pulley (the bottom sprocket)

TIMING BELT

DISASSEMBLY

1. Lift the vehicle by using of jack.
2. Remove the engine support bracket. (14 mm bolt and 2 nuts, 17 mm bolt)
3. Remove the power steering belt.
4. Remove the air conditioning compressor belt.
5. Remove the alternator belt.
6. Remove the coolant pump pulley.
7. Remove the crankshaft pulley.
8. Remove the timing belt cover.
9. Move the timing belt tensioner pulley toward the coolant pump and temporarily secure it.
10. Remove the timing belt.
11. Remove the camshaft from the camshaft sprocket.
12. Remove the crankshaft sprocket and flange.
13. Remove the timing belt idler.
14. Remove the timing belt tensioner.

REASSEMBLY

1. Install the flange and crankshaft sprocket as shown. Pay close attention to their mounting
directions.
2. Install the camshaft sprocket and tighten the bolt to the specified torque.
Tightening torque
Camshaft sprocket bolt:
80-100 N.m (800-1000 kg.cm, 59-74 lb.ft)
3. Install the idler and tighten the idler bolt to the specified torque.
Tightening torque
Idler bolt: 43-55 N.m (430-550 kg.cm, 32-41 lb.ft)
4. Align the timing marks of the camshaft sprocket (A) and camshaft bearing cap (B).
Then align the timing marks of crankshaft sprocket and front case with the No. 1 piston placed at
top dead center on its compression stroke as shown in the illustration.
5. To install the timing belt tensioner, first mount the tensioner, spring, and spacer. Temporarily
tighten the bolts. Next, temporarily tighten the tensioner long hole side washer and bolts. Install
the bottom end of the spring against the front case as shown in the illustration.
6. Secure the tensioner, positioned towards the water pump.
7. Install the timing belt on the crankshaft sprocket. (1) Crankshaft sprocket, (2) Timing belt idler,
(3) Camshaft sprocket and then (4) Timing belt tensioner.
8. Install the timing belt on the camshaft sprocket. When the timing belt is installed on the camshaft sprocket, make sure that the tension side is tight. Then, check to ensure that when the tension side is tightened by turning the camshaft sprocket in a reverse direction and all timing marks are in line.
9. Tighten the tensioner bolts.
Tightening torque
Tensioner attaching bolt:
20-27 N.m (200-270 kg.cm, 15-20 lb.ft)
10. Turn the crankshaft two turns in its operating direction (clock-wise) and realign the camshaft
sprocket timing mark with the top dead center position.
11. Then recheck the belt tension Verify that when the tensioner and the tension side of the timing belt are pushed in horizontally with a moderate force [approx. 49 N (11 lb)], the timing belt cog end is approx. 1/2 of the tensioner mounting bolt head radius (across flats) away from the bolt head center.
12. Install the timing belt cover.
Tightening torque
Timing belt cover bolt:
8-10 N.m (80-100 kg.cm, 6-7 lb.ft)
13. Install the crankshaft pulley. Make sure that the crankshaft sprocket pin fits the small hole in the
pulley.
Tightening torque
Crankshaft pulley bolt:
140-150 N.m (1400-1500 kg.cm, 103-111 lb.ft)
14. Install the water pump pulley.
15. Install the alternator belt and adjust the belt tension.
16. Install the air conditioning compressor belt and adjust the belt tension.
17. Install the power steering belt and adjust the belt tension.
