Getting Started
If your water pump has not
been replaced, now is a
good time to do it. We cover
water pump replacement in
another tutorial.
We started with the engine
removed from the vehicle;
in order to get us on the
same page, follow the
procedures below.
1.Place vehicle in park
2.Chock wheels
3.Disconnect battery
4.Remove upper radiator hose
5.Remove fan shroud (4x10mm)
6.Remove cooling fan (4x12mm)
7.Remove cooling fan pulley
Timing cover
Using needle nosed pliers, remove the clips to
the timing belt cover (x2).
Timing cover
continued
Remove all bolts attaching the timing cover (4x10mm).
Timing cover

Remove plastic timing cover and
place the bolts/clamps inside.
Setting TDC
cam sprocket
Injection pump
pulley
crank pulley
Using a breaker bar, (22mm socket) rotate
engine clockwise to TDC.
Setting TDC
crank pulley
cam sprocket
Make sure that all of
these marks line up.
Start from the crank
pulley, then check
the cam sprocket,
then the injection
pump.
On the injection pump
the notch is on the rear
side of the pulley
injection pump
timing belt tensioner
Remove the bolts attaching
the timing belt tensioner
(2x10mm).
timing belt tensioner
Remove belt!
Timing belt cover
I recommend
replacing the cam
seal at this time as
it’s easy to get to.
This is a good time to clean up the plastic
cover.
Cam seal replacement
To keep the
sprocket from
moving, use the
old belt as a belt
wrench. An
impact wrench is
a must here!
Careful to not change
the TDC orientation of
the cam sprocket
while loosening the
bolt
WIth the alternator, a/c compressor, and timing belt
removed, begin by removing the camshaft sprocket
bolt and woodruff key (19mm).
Careful not to lose
the woodruff pin
during the process
Remove pulley with a few “light”
taps with a rubber mallet.
Remove the bolts attaching the timing
cover (8x10mm).
Using a rubber mallet and applying tension
with a free hand, tap the rear of the intake
side of the cover. Slide the cover off of the
cam, then lift up and out avoiding the
cam tensioner.
Using needle nosed pliers, gently
remove the cam seal.
Pay special attention
to the seam directly
below the camshaft
opening.
Using a wire wheel (pictured) and an electric drill,
clean all mating surfaces to remove old sealant,
dirt, and oil.

With a cleaned cover, press the new seal in.
It’s best to try and use your fingers or other
soft instruments as these seals are easily
damaged.
the closest thing
I can find to the
factory sealant
is Hondabond.
Great stuff!
Using Hondabond, run a bead along the seam
and distribute evenly with your finger.
It may not be necessary, but most of these
covers have sealant on the bottom of the cover
from factory. I recommend repeating the
practice.
Now the cover is ready to install.
When installing the cover, begin with the
bottom of the cover, then put it into position.
Next, slide the cover over the camshaft then
press and hold for 10 seconds.
Install cover bolts and tighten to 9 ft/lbs in a
crosshatch pattern.
Careful to not change
the tdc orientation of
the cam sprocket
while tightening the
bolt
Place the woodruff key into the slot
on the camshaft.
Slide cam sprocket into position
Install the bolt and torque to 72 ft/lbs
using an impact wrench.
Cover and cam sprocket installed.
Tensioning the tensioner
Careful! The
tensioner can slip
out of the vise and
go flying! This
procedure should
take 3-4 minutes.You
should not be able
to tighten without
stopping. if you can,
the tensioner is bad
Place the tensioner in a vise and slowly tighten
the vise until the holes in the tensioner line up.
Slide a small flat-blade screwdriver or other
hardened metal pin through the holes in order to
keep the holes lined up.
Install tensioner but leave it loose for now.
(2x10mm)
timing belt install
Triple check the
notches on crank, IP,
and cam to ensure
alignment during
each step of this
process
Starting with the injection pump, slide the belt
over the pulley then gauge the distance in order
to have the yellow line on the cam sprocket line
up with the mark on the gear.
Adjust until perfect.
Do not slide the belt
over the tensioner
until this orientation is
right
timing belt install
Slide belt over tensioner at this time.
Check all your alignment marks one more time, then
tighten the 2 bolts securing the tensioner to 9 ft/lbs.
(2x10mm)
Using needle nosed pliers remove pin on tensioner.
timing belt install
IMPORTANT:if any of
the marks are not
right, start over!
Tip: When rotating
the engine-once
you feel
resistance, wait 5
seconds then
continue
Check your marks to ensure they have not moved.
Using a breaker bar and turning clockwise, rotate the
engine over 3 times watching all 3 timing marks during
each rotation.
timing belt install
Replace the plastic cover and install cover bolts
and tighten to 9 ft/lbs (4x10mm).
Install (2) metal clamps.
Finishing up
1.Reinstall cooling fan assembly
2.Reinstall fan shroud
3.Reinstall upper radiator hose
4.Reconnect battery
5.Remove radiator cap
6.Start engine
