Set TDC according to the mark on the exhaust camshaft pulley (when installed according to the marks on the crankshaft pulley, the piston of either the 1st or 4th cylinder may be in this position). After this, be sure to check that the marks on the toothed pulley of the crankshaft match (if the generator drive pulley and the lower front timing cover have been removed). If the marks on the crankshaft pulley do not match, then the valve timing is out of alignment (piston of the 1st cylinder is not set to TDC). In this case, it is necessary to remove the exhaust camshaft drive belt and turn the crankshaft until the marks are aligned.
Helpful Hint: Since it is inconvenient to turn the crankshaft using the pulley mounting bolt, you can do this in the following ways:
- 1) engage any gear (better the fourth) and slowly roll the car until the marks align;
- 2) engage any gear and lift one of the front wheels. Then turn the lifted wheel until the marks align.
When setting the piston of the 1st cylinder to the BMT position, the marks on the camshaft pulleys must be located opposite each other...
...and the mark on the toothed pulley of the crankshaft must be aligned with the slot on the rear cover of the timing drive.
You will need: a 10 mm socket head, a spanner (or socket head) "at 22".
1. Remove the upper and lower front timing belt covers (see "Replacement and adjustment of the belt tension, timing drive of the F18D engine").
2. Turning the engine crankshaft by the bolt securing its pulley, align the mark on the crankshaft pulley with the cutout on the rear cover of the timing drive.
3. Check the alignment of the marks on the camshaft pulleys.
