Set TDC according to the mark on the camshaft pulleys (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 is removed). If the marks do not match, then the installation of the gas distribution phases is violated (1st cylinder piston not set to TDC). In this case, it is necessary to remove the 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 IV) and slowly drive the car until the marks are aligned;
- 2) turn on any gear and hang out one of the front wheels, then turn the hanging wheel until the marks are aligned.
When installing the piston of the 1st cylinder at TDC, the marks on the camshaft pulleys must be located opposite each other,..
... and the mark on the crankshaft pulley must match the slot on the rear cover of the timing gear.
1. Remove timing belt covers (see «Replacing the timing belt and its tension roller»).
2. Turn the engine crankshaft by the crankshaft pulley mounting bolt until the mark on the crankshaft pulley aligns with the cutout on the rear timing cover.
3. Check up coincidence of labels on pulleys of camshafts.
