Cam shaft and timing belt diagram 2008 Volvo S40 2.4

Obviously, this is a tricky issue, so good you got the cam locking tool, but did you set the VVT when reinstalling timing belt, you have to set the pulley to full clockwise position before timing and aligning timing marks. I assume you did align to crank pulley, at least I hope so or your valves will be destroyed. Do you have dual VVT vehicle, or single VVT?

all engines are set on TDC
you did not mention the engine or if it is chain or belt so this is for chain.2.8L
crank key is in line with lh cam shaft center
LH key is vertical
RH key is facing down to the left in the 8o'clock position
for belt drive engines the crankshaft mark is 12 o'clock and both cam shafts are at12 o'clock on the head and two other marks facing2oclock on the lh cam and 10 o'clock on the rh cam
It is complicated to explain but it is in the workshop manual as to how to set it up correctly

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.

well timing on a volvo can some times a pain I would say start with ( with out looking at my self ) checking the timing belt or chain is not broken, by looking in side the oil fill cap at the cam shaft to see if it is moving. If the cam is moving it may have jumped time. you would need to reset the timing, also check your harmonic balencer for proper alingment to the crank shaft, and timing marks line up . look for timing mark alingment in your owner's manul.

hope this helps you if it dosen't please give me more information on your problem with the timing in detail.

the variable timing wheel should be on the inlet cam. the timing marks should align on cams upper of rear inner belt cover the crank upper of oil pump housing

camshaft pulley has a notch which lines up with notch on cam cover at approx 11o'clock, crankshaft marks also approx 11 o'clock and the aux shaft for distributer has marks at 9o'clock

check your distributor position,double
check all marks again,make sure when u line up
the crank marks at #1 cyl. at compression and cam shaft marks!!

I hope you've solved the problem by now, but there are alignment marks on the crank shaft (top pulley), idler (lower side), and cam shaft (smaller, bottom pulley) which should be aligned with stationary marks on the timing belt rear cover.

The belt has marks that align with the aforementioned marks (lines). The double marks on the belt align with the camshaft marks and the single marks with the others.

Loosen the tensioner clamp (nut) to allow the spring loaded tensioner to press on the belt and retighten the nut.

Rotate the crank shaft (clockwise, probably two revolutions) and make sure the pulley marks realign to the marks on the cover (they don't have to realign with the marks on the belt).

Rotate the crank shaft a full revolution once the belt is on and check that alignment is preserved.

Periodically loosen and retension the tensioner nut (access through a hole in the cover) to ensure that tension is maintained as the belt relaxes.

I replaced mine on the same car.  I borrowed the NAPA timing belt book to get the timing marks.  There are three that need to be aligned.  I would suggest going to NAPA to buy the belt ($25) and while there, ask to see that book so you can write down the timing marks.  The mark on the crank shaft gear is on the inside of the gear, while the cam gear is on the outside of the gear.  Or, you could just buy the book.  It's still a lot cheaper than paying someone to replace the belt.
