Position the grooves of the camshafts 1, Figure 5, horizontally and offset downward from the shaft axles, if necessary turning the camshafts using a tool (tool Mot. 1496, replaceable head 16, extension, ratchet wrench).

Fit tool 1, Figure 6, for setting the valve timing on the engine and secure with bolt 2 (tool Mot. 1496, replaceable head 10, extension, crank).

Place the marks on the spokes of the camshaft pulleys vertically upwards.

Install a new tensioner roller 2, Figure 4, of the timing belt, inserting its protrusion into the groove.

Screw in, without tightening, the nut 1 of the tension roller axle (replaceable head 16, ratchet wrench).

Install the crankshaft toothed pulley 6.

Install a new timing belt 3.

Install a new timing belt pulley 4. The tightening torque of the bolt 5 of the timing belt idler roller is 50 Nm (5.0 kgf.m) (tool Mot. 1368, replaceable head 16, ratchet wrench, torque wrench).

Using a 6 mm hexagon wrench, align the movable pointer A, Figure 7, with the recess B of the fixed pointer, turning the eccentric 1 clockwise.

Tighten the timing belt tension roller nut to a torque of 7 N.m (0.7 kgf.m) (replaceable head 16, torque wrench).

Install the bottom cover 2, Figure 3, of the timing drive. The tightening torque of the bolts 1 of the lower timing drive cover is 12 Nm (1.2 kgf.m) (replaceable head 8, ratchet wrench, torque wrench).

Install the tool 1, Figure 8, TDC on the cylinder block (TDC tool Mot. 1489 or 67.7820-9701 L).

Install the crankshaft pulley.

Unscrew bolt 2, figure 6, fasteners of tool Mot. 1496 and remove the tool 1 for setting the valve timing (replaceable head 10, extension, crank).

Remove the TDC clip from the cylinder block (TDC clip Mot. 1489 or 67.7820-9701 L).

Checking the tension of the timing belt on the K4M engine

Turn the crankshaft two turns clockwise (when viewed from the timing side) and until the previously applied marks are aligned (on the phase regulator pulley), install the TDC lock on the cylinder block.

Carefully bring the crankshaft up to the stop in the retainer (replaceable head 18, ratchet wrench).

Remove the TDC clip from the cylinder block (TDC clip Mot. 1489 or 67.7820-9701 L).

Ensure that the movable indicator A, figure 7, is opposite the recess B of the fixed indicator, if this is not the case:

- unscrew the nut 1, Figure 4, fastening the tension roller by no more than one turn, holding the movable pointer with a 6 mm hex wrench (replaceable head 16, ratchet wrench);

- smoothly bring the movable pointer up to alignment with the recess, turning the eccentric clockwise.

Tighten the timing belt tension roller nut to a torque of 27 Nm (2.7 kgf.m) (replaceable head 16, torque wrench).

Checking the installation of the valve timing on the K4M engine

Before checking the camshaft timing, make sure that the movable indicator A, Figure 7, the tensioner roller and the notch B of the fixed indicator are in the correct position.

Install the tool 1, Figure 8, TDC on the cylinder block (TDC tool Mot. 1489 or 67.7820-9701 L).

Carefully bring the crankshaft up to the stop in the retainer (replaceable head 18, ratchet wrench).

Install (without using force) tool 1, figure 6, for setting the valve timing (the grooves at the ends of the camshafts 1, figure 5 must be horizontal and displaced downward from the shaft axles) (tool Mot. 1496).

If tool Mot. 1496 does not fit, then you need to re-set the valve timing and adjust the timing belt tension.

Remove tool Mot. 1496 for setting the valve timing.

Remove the TDC clip from the cylinder block (TDC clip Mot. 1489 or 67.7820-9701 L).

Install the window cover on the lower timing cover, making sure the pin fits into the recess.

Operations are common for all vehicle configurations
