Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need
parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the timing belt on this 2002 Volvo
V70 with the 2.4 liter non-turbo engine. The items you'll need for this are a new timing
belt kit from 1AAuto.com, 10, 12, 14, 19, and 30mm sockets and a ratchet with an extension,
T30 Torx bit, 6mm Allen wrench, flat blade screwdriver, wire cutters, locking pliers,
jack and jack stands and a torque wrench.
You want to start off by removing these two T30 Torx bolts. We'll just fast forward as
Don does that. Now flip up the clip on this side and the clip over here on this side,
and pull that shield off. Use your wire cutters to clip the wire tie. Then using a flat blade
screwdriver, pry up your power steering bottle and pull the hose out of that clip and set
the bottle aside. Your serpentine belt tensioner is right here. Using a 14mm socket and ratchet,
just push towards the front of the car and this will release tension on that belt and
you can pull it off. Carefully release the tensioner and pull the belt off the rest of
the way.
Next, you want to remove this 10mm bolt right in here. Now pull this cover up and out. Now
using a 19mm socket and ratchet, you want to loosen up your lug nuts and if you don't
have air powered tools, you want to loosen them while they're on the ground, raise the
vehicle, remove them the rest of the way and pull your wheel off.
Next, remove these two 10mm bolts inside the inner fender. Then, remove this panel. Now
pull this panel back and using a pair of locking pliers just clamp it right here. Now you want
to remove these two 10mm bolts right here and we use a 10mm wrench for this. Once those
are removed, you can pull this panel down and out.
All right, the next step in this repair is going to be to set our timing marks. Now there
are marks on each one of these cams, the intake and the exhaust cam as well as the crank shaft
down there. You can see the crank pulley. This is how we're going to do it. We're going
to put our cam cover back on and you see it's got two notches here. Install it fully, back
into the clips on each side. Now what we're going to do is we're going to go down with
a 30mm socket and ratchet on the crack pulley down there. You see the nut. We're going to
go through the wheel well where we just took the wheel off. What we're going to do is we're
going to turn it until the marks that are very subtle here on the cam, there and over
here, line up with the corresponding notches in this cover. That's important but it's also
important that the crank shaft notch â€“ it has a notch and teeth lines up with a tooth
â€“ the tooth lines up with a post on the side of the engine block. If you come
from over here, you can just about make it. We'll get an up close shot for you as we turn
it. I'm going to go ahead now with my 30mm ratchet and socket and turn it until I get
those marks to line up but before I do that I'm going to use just a marker or a red marker
and make those a little bit more visible.
All right so here's the setup I'm using. Go in on the crank pulley and I'll turn clockwise,
this slowly and you can see those marks starting to come up. Weâ€™re getting there. Now
what we're going to do is focus our attention down on the crank. It's really tough to see
the mark, I'm going to try and point it out. On two of the teeth on your crank, you'll
see these two notches that we have circled right here, and you want to locate those and
then line them up so that this post that comes down is directly in between those two notches.
When you're done, it should look something like this.
All right, the next stage of the repair is to take the belt off and in order to do that
we have to loosen up on the tensioner. There's three different points of tension that we're
going to set it to when we go to put the new tensioner in and we're going to use a 6mm
Allen key on this elliptical here. This is very crucial that we get this right and this
is temperature sensitive. Our vehicle's been running for a while now; it's in the hot.
If it was cold, you'd want to set your tensioner here, right here. We'll go through this later
as we do this. This is warm and this is hot. This is the way that we're going to set it
when we go to put the new one in but I'm just showing you now because we have to slacken
off the one that we have in the car and you'll see here that ours is indeed in the hot position,
the furthest to the right tab, there. If we do this repair in reasonable amount of time,
it's probably still going to be hot and that's what we're going to go ahead and set our new
tensioner.
For right now, we're going to loosen up on the 10mm that goes through the tensioner and
then we're going to use our Allen key to slacken it off. You only want to loosen this bolt
a couple of turns. Now using a 6mm Allen wrench, just loosen that up by turning it all the
way to the front of the vehicle. Now you can just remove this cover again and pull your
timing belt off. Once you've got the majority of the belt off, you can remove your tensioner.
Just remove that bolt the rest of the way and pull the tensioner up and out. Now, pull
the timing belt down through the wheel well and, using your wire cutters, just clip the
belt and pull it out the rest of the way.
Next you want to remove this pulley and it's held in with two 12mm bolts. We'll fast forward
as Don removes those. Now just pull that pulley up and out.
On the left are the old timing belt, tensioner, and idler pulley. On the right are the new
ones from our timing belt kit and you can see they're identical and they're going to
fit exactly the same. Replace the idler pulley and tighten up those two 12mm bolts.
We're going to go back in with the tensioner, the new one here, and it's important to seat
it correctly. You can see this tab and this tab. These are going to go on either side
of this casting right here. Put the tensioner back into place and tighten that bolt, and
really you're just tightening it preliminarily, you don't want it too tight so it can still
move.
Now, feed your timing belt back up and around the crank pulley. We've got the belt on the
crank pulley and what we're going to do is we're going to wedge a screwdriver in between
the belt and the post that comes out on the block so that the belt doesn't move or skip.
This is just for purposes of installing the belt. Youâ€™ve got to find the spot.
Now it's up in there, so now the belt won't skip on the teeth while we set it up on the
pulleys up above. Now put the belt around the rest of the pulleys. Now replace the cover
so that you have the notches as a reference point. You want to make sure that this line
lines up with the notches as it did before. Now, we're going to go ahead and tighten or
tension up the belt tensioner and lock it up into place. We're using that 6mm Allen
and the 12mm socket. Go ahead and put it in there, in the slot and the engine at this
point is warm. It's was hot before, so we're going to tension it to warm, which is right
there in the middle. Once you've got it where you need it, go down with your 12mm socket
and tighten up on that stud on the bolt. Just a quick reminder, here is the cold setting
then there's cold, warm and hot. Remove the screwdriver.
All right, at this point, now, we're going to use our crank turning setup here with the
30mm breaker bar and what we're going to do is give it one full revolution, check our
cam marks, crank mark and our tensioner.
Once you've checked it and made sure that all the marks like up, you can replace this
panel. Then replace those two 10mm bolts that hold it into place. Now push this panel back
down and replace that other panel and those two 10mm bolts.
Fast forward as Don replaces the wheel and those 19mm lug nuts and you want to tighten
them preliminarily and lower the vehicle and tighten them the rest of the way and torque
each of these lug nuts in a crossing pattern to 100 foot-pounds.
Now, replace this cover and you just want these two tabs to go down into these two slots.
Lower the cover down into place and it helps if you push this cover back. Now, put the
top cover back into place. Then replace that 10mm bolt on the side there.
Now, when you go to put your serpentine belt, this is your belt diagram. You want it to
follow this order as you put it back on the pulleys. We'll fast forward as Don does this.
Again, if it doesn't seem like it's going on right just refer to that belt diagram.
Now, line up these tabs and push your power steering bottle back down into place. Push
the hose back into place and reclamp it. Then replace those two T30 bolts and you're all
set.
