How do you Change the Timing Belt for a 1999 Daewoo Leganza?

Answer 1

The 1999 Daewoo Leganza has two engines: the 2.0L and the 2.2L. The procedure for changing the belt is the same for both engines. The manufacturer recommends changing the timing belt every 72,000 miles, as both engines are interference engines. If the belt stretches so far that the tensioner cannot take up the slack, or if the belt breaks, the valves will most likely hit the pistons, causing extensive engine damage. No special tools are needed to change the timing belt.

1.

Step 1

Disconnect the negative battery cable using the appropriate wrench. Lay the cable aside, making sure you don't let it touch metal. Raise the front of the Leganza with the floor jack, then support it with jack stands. Remove the floor jack.

2.

Step 2

Disconnect the intake air temperature sensor by unplugging the wiring harness. The intake air temperature sensor is on the air intake near the air filter. Disconnect the breather hose and the air intake (air filter hose). Remove the air cleaner housing and air cleaner. Use the set of sockets and wrenches to remove all items.

3.

Step 3

Remove the right front wheel using the lug wrench. Remove the right front fender inner splashguard. Remove tension from the accessory belt tensioner using a wrench, then remove the accessory drive belt. Remove the crankshaft pulley bolts using the appropriate size sockets, then pull the pulley off.

4.

Step 4

Place the 2-by-4-inch board on the floor jack. Slide the jack under the oil pan and jack it up enough to touch the oil pan or the bellhousing on the transmission, to support the engine. Remove the right engine mount bracket. Remove the Power Steering hose bracket and the bolt using the appropriate size socket. Remove the timing belt cover using the appropriate socket.

5.

Step 5

Turn the crankshaft counterclockwise using the appropriate socket. Do so until the crankshaft timing mark lines up with the notch at the 6 o'clock position, and the dots on both camshaft sprockets line up with the timing marks at the 12 o'clock position on the head. Each camshaft sprocket has two marks. The sprockets are interchangeable. When facing the engine, the left camshaft sprocket needs to match the "Intake" mark, and the right camshaft sprocket needs to match the "Exhaust" mark.

Step 6

Loosen the timing belt tensioner bolt. Turn the tensioner away from the belt (clockwise), then tighten the bolt to hold the tensioner out of the way. Remove the timing belt.

7.

Step 7

Check that the timing marks are still perfectly aligned. Install the timing belt starting at the crankshaft pulley. Work your way counterclockwise around the top of the tensioner, the outside edge of the water pump, the inside edge of the idler, the outside of both camshafts and the inside of the right idler, keeping the belt tight on the nontensioned side.

8.

Step 8

Loosen the tensioner pulley bolt. Turn the tensioner counterclockwise using a wrench until the pointer on the tensioner is aligned with the notch on the block. Tighten the tensioner bolt to 18 foot-pounds of torque.

9.

Step 9

Turn the crankshaft counterclockwise (slowly) for two turns until the timing marks are lined up again, as shown in Step 5. Check the tensioner pointer to see that it is still aligned. If not, repeat steps 8 and 9.

10.

Step 10

Install the rest of the parts in reverse order of removal. Tighten the crankshaft pulley bolts to 15 foot-pounds of torque.
