How to: Timing belt replacment on a 1.4/1.5 8 valve SOHC

Post by MMamdouh »

Tools Required
? J-42492 Timing Belt Adjuster

Image

? KM-470-B Angular Torque Gauge

Image

Removal Procedure

1.Disconnect the negative battery cable.
2.Disconnect the intake air temperature (IAT) sensor connector.
3.Disconnect the air intake tube from the throttle body.
4.Disconnect the breather tube from the valve cover

Image

5.Remove the air filter housing bolts.
6.Remove the air filter housing.

Image

7.Remove the right front wheel.
8.Remove the right front splash shield.
9.Remove the A/C compressor drive belt, if equipped.

Image

10.Remove the alternator drive belt.
11.Remove the power steering pump pulley bolts, if equipped.


if you have an aveo/gentra then drop steps 9, 10 & 11 and Remove the serpentine accessory drive belt by rotating the tensioner pulley bolt to clockwise using DW110-080

Image

12.Remove the power steering pump pulley, if equipped.
13.Remove the crankshaft pulley bolt.
14.Remove the crankshaft pulley.

Image

15.Remove the upper front timing belt cover bolts.
16.Remove the upper front timing belt cover.
17.Remove the lower front timing belt cover bolts.
18.Remove the lower front timing belt cover.

Image

19.Remove the power steering pump mounting bolts, if equipped.
20.Install the crankshaft pulley bolt.
21.Using the crankshaft pulley bolt, rotate the crankshaft clockwise until the timing mark on the crankshaft gear is aligned with the notch at the bottom of the rear timing belt cover.

Image

22.Slightly loosen the coolant pump retaining bolts.
23.Using the timing belt adjuster J-42492, rotate the coolant pump counterclockwise to release the tension on the timing belt. Important: Remove the timing belt behind the power steering pump.

Image

24.Remove the timing belt.


if you have an aveo/gentra you will have to support the engine by a floor jack and remove the front engine mount to remove the timing belt.

Installation Procedure

1.Align the timing mark on the crankshaft gear to the notch on the bottom of the rear timing belt cover.

Image

2.Align the timing mark on the camshaft gear to the notch on the cam cover. Important: Insert the timing belt behind the power steering pump.

In case the cam mark is not aligned correctly: rotate the cam gear in any direction - preferably the one that will make the shortest adjustment - and in case the cam gear seized, do not and I repeat do not use excessive power to rotate it instead; go the other way round till the marks are aligned.

3.Install the timing belt.


if you have an aveo/gentra you will have to put back the front engine mount and remove the floor jack that is supporting the engine.


Image

4.Rotate the coolant pump clockwise using the timing belt adjuster J-42492.

Image

5.Rotate the coolant pump clockwise until the adjust arm pointer of the timing belt automatic tensioner is aligned to the notch in the timing belt automatic tensioner bracket.
6.Tighten the coolant pump retaining bolts.
7.Rotate the crankshaft two full turns clockwise using the crankshaft pulley bolt.
8.Loosen the coolant pump retaining bolts.
9.Rotate the coolant pump until the adjust arm pointer of the timing belt automatic tensioner is aligned with the pointer on the timing belt automatic tensioner bracket.
10.Tighten the coolant pump retaining bolts. Tighten the coolant pump retaining bolts to 10 Nm (89 inch lbs.).

Image

11.Remove the crankshaft pulley bolt.
12.Install the power steering pump mounting bolts, if equipped. Tighten the power steering pump mounting bolts to 25 Nm (18 ft. lbs.).
13.Install the upper and lower front timing belt cover.
14.Install the upper and lower front timing belt cover bolts. Tighten the upper and lower front timing belt cover bolts to 10 Nm (89 inch lbs.).

Image

15.Install the crankshaft pulley.
16.Install the crankshaft pulley bolt. Tighten the crankshaft pulley bolt to 95 Nm (70 ft. lbs.) using a torque wrench. Using the angular torque gauge KM-470-13, tighten the crankshaft pulley bolt30 degrees plus 15 degrees.

Image

17.Install the power steering pump pulley, if equipped.
18.Install the power steering pump pulley bolts, if equipped. Tighten the power steering pump pulley bolts to 25 Nm (18 ft. lbs.).
19.Install the alternator drive belt.
20.Install the A/C compressor drive belt, if equipped.

Image

if you have an aveo/gentra then drop steps 19 & 20 and put back the serpentine accessory drive belt by rotating the tensioner pulley bolt to anti clockwise using DW110-080

Image

21.Install the right front splash shield.
22.Install the right front wheel.
24.Install the air filter housing.
25.Install the air filter housing bolts. Tighten the air filter housing bolts to 12 Nm (106 inch lbs.).

Image

26.Connect the air intake tube to the throttle body.
27.Connect the breather tube to the valve cover.
28.Connect the IAT sensor connector.

Image

29.Connect the negative battery cable.

NOTE: it is preferable to replace the timing belt tensioner and the water pump during the timing belt replacment, a tensioner failure is just as bad as a breaking timing belt and replacing the tensioner and\or water pump will require the same amout of work you are already doing to replace the belt.
