QuestionI make most of my car's maintenance and repairs and I have a fair knowledge of mechanics, I would like to change the timing belt myself; is it too difficult? can you explain to me how can I do it?
if so a diagram would be very helpful
Thank you very much
Answer SERVICE MANUAL
Applies to: Accent 2000-2002
GROUP
Engine Mechanical System Timing System
DISASSEMBLY
Loosen the coolant pump pulley bolt.
Loosen the generator bolt.
Remove the coolant pump pulley and belt.
Remove the crankshaft pulley.
Remove the timing belt cover.
Move the timing belt tensioner pulley toward the coolant pump and temporarily secure it.
Remove the camshaft from the camshaft sprocket.
Remove the camshaft sprocket.
Remove the timing belt.
NOTE
If the timing belt is reused, mark with an arrow to indicate direction of rotation (or the front of the engine) to make sure that the belt is reinstalled in the same direction as before.
Remove the crankshaft sprocket bolts. Remove the crankshaft sprocket and flange.
Remove the timing belt tensioner.
REASSEMBLY
Install the flange and crankshaft sprocket as shown. Pay close attention to their mounting directions.
Tightening torque
Crankshaft sprocket bolt :
140-150Nm (1400-1500 kg.cm, 103-111 lb.ft)
Install the camshaft sprocket and tighten the bolt to the specified torque.
Tightening torque
Camshaft sprocket bolt :
80-100Nm (800-1000 kg.cm, 59-74 lb.ft)
Align the timing makrs of the camshaft sprocket and crank shaft sprocket, with the No.1 piston placed at top dead center on its compression stroke.
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.
Secure the tensioner, postponed towards the coolant pump.
Install the timing belt on the crankshaft sprocket.
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, all timing marks are in line.
Loosen the tensioner mounting bolts 1 and 2 in that order as shown. This will apply spring tension to the timing belt only. Check the belt to ensure that it is not out of position.
Tighten the tensioner tightening bolts 1 and 2 in that order. If the bolt 1 is tightened first, the tensioner will move with the belt in the direction that the belt is tightened.
Give the crankshaft one turn in operating direction (clock-wise) and realign crankshaft sprocket timing mark with the top dead center position.
CAUTION
Do not turn the crankshaft in a counterclockwise direction. The crankshaft should turn smoothly.
Loosen the tensioner attaching bolt 1 and 2 in that order.
Tighten the tensioner attaching bolts 2 and 1 in that order to the specified torque.
Tightening torque
Tensioner attaching bolt :
20-27Nm (200-270 kg.cm, 15-20 lb.ft)
