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 can be in this position). After that, be sure to check that the marks on the crankshaft toothed pulley match (if the alternator drive pulley and the lower front cover of the timing drive are removed). If at the same time the marks on the crankshaft pulley do not match, then the installation of the valve timing is violated (1st cylinder piston 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 by the pulley mounting bolt, you can do this in the following ways:
- 1) turn on any gear (better than the fourth) and slowly drive the car until the marks are aligned;
- 2) Shift into any gear and jack up one of the front wheels. Then turn the suspended wheel until the marks are aligned.
When installing the piston of the 1st cylinder in the BMT position, the marks on the camshaft pulleys must be located opposite each other...
... and the mark on the crankshaft pulley must be aligned with the slot on the rear cover of the timing gear.
You will need: socket head «on 10», box key (or end head) «at 22».
1. Remove the upper and lower front timing belt covers (see «Replacing and adjusting the belt tension, timing drive of the F18D engine»).
2. Turning the engine crankshaft by the bolt securing its pulley, achieve alignment of the mark on the crankshaft pulley with the cutout on the rear cover of the timing gear drive.
3. Check up coincidence of labels on pulleys of camshafts.
