Don't panic about the marks too much,find top dead centre on cyl no 1,good chance once you have you will find something that does line up between the block/timing case and the pulley. don't forget once it is fitted to ALWAYS wind the engine by hand atleast 2 times to make sure the pistons don't hit valves before starting.

How do i do valve timing from scretch after timing belt broke on a volvo t5,2.3l s60


If the belt broke while the motor was running, the motor is likely badly damaged since, I believe, the five cylinder Volvo engines are "interference engines". The crankshaft and pistons keep moving while the car is in gear and still moving, but the valves stop dead the instant the timing belt breaks. The pistons would have hit some of the valves, cracking or badly damaging the cylinder head and some pistons. If the motor is not damaged internally, though, just line up the timing marks on the cam shaft sprockets and the crankshaft sprocket and put on a new belt. Go online for a diagram of how to align the timing marks.

Replacing a timing belt on a 740 GL Volvo 1990 model


Replacement of the timing belt on B230F engines is fairly straightforward. Note that you will need the proper tool to secure the crankshaft sprocket during removal procedures. Obtain the timing belt tensioner as well; it is designed to last only as long as the timing belt.
Begin by cleaning the area around the timing belt upper cover.
Remove the upper cover.
Remove the drivebelts on all accessory components.
Remove the fan (if you have a mechanical fan). Carefully leverage it out of the shroud. It may be necessary to remove the shroud as well - two 7mm bolts secure it to the radiator.
Remove the lower bellhousing cover at the rear of the engine.
Turn the crankshaft to bring the engine to Number 1 cylinder, TDC, firing. The timing marks will align when this is done.
Remove the crankshaft sprocket bolt. It may be very tight, and clearance is quite limited. Take care not to move the crankshaft from its set position.
Inspect all front oil seals before continuing, along with the water pump condition. If anti-boil weeps from the weep hole on top, you must replace the water pump or else it will contaminate the new belt.
Lock the timing belt tensioner in position. This can be done with a small nail, bringing it back and out of the way.
Remove the timing belt.
Replace all oil seals that leak, are weak or missing. Oil will ruin the new timing belt.
Installation is essentially a reversal of removal, after the tensioner is replaced and unlocked, spin the crankshaft sprocket two complete turns, noting if the timing is correct by way of the pointers aligning with the marks in the rear timing cover. Push down on the belt to ensure it seats correctly. Tighten the tensioner to the specified torque.
Install the cover, rear bellhousing cover (if removal was necessary) and nuts. Screw the backplate onto the front timing cover.
Install the fan and fan shroud.
Refill the coolant if the water pump was changed.
After double-checking installation items, road test the vehicle after allowing it to warm up to check for coolant or oil leakage.
After 600 miles, remove the rubber plug at the front of the timing cover. Loosen and tighten the tensioner bolt. Place your labels indicating mileage and date of timing belt drive maintenance at the front of the engine.

Engine swap, car will not start


It sounds like you don't have the correct flex plate and it is throwing the timing off not letting it fire at the correct time.

On the 92, the belt closest to the engine goes around the power steering pump, water pump, and crankshaft pulley.

The second belt goes around the alternator and the crankshaft pulley.

The third belt goes around the a/c and crankshaft pulley.
