NorE: The items m arked * 1, *2, +3, *4 and +5 on above chan are described as folows:*1: Always use Genuine Honda Manual Transmission Fluid (MTF). Using motor oil can cause stiffer shifting because itdoes not contain the proper additives.*2: Always use Genuine Honda premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affectshift quality.+3: Use Genuine Honda cVTfluid only usingotherfluid can affect tra nsmission operation and may reduce transmission life.*4: Always use Genuine Honda DoT3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and dec.ease the lifeof the svstem.*5: Always use Genuine Honda Power steering Fluid. using any other type of power steering fluid or automatrc transmissionfluid can cause increased wear and poor steering in cold weather.

Removal
NOTE:
. Replace the timing belt at 105,000 miles (168.000 km)
according to the maintenance schedule (normal con-
ditions/severe conditions).
lf the vehicle is regularly driven in one or more of the
followlng conditions, replace the timing belt at 60.000
miles (U.S.A.) 100,000 km {Canada).
.In very high temperatures (over 110'F.43'C)
. In very low temperatures (under -20'F, -29"C)'
! Turn the crankshaft pulley so the No. 1 piston is at
top dead center (TDC) before removing the belt (see
page 6'21).
. Inspect the water pump before installing the timing
belt {see Page 10-14).
1. Remove the splash shield (see page 5-7).
2. Loosen the mounting bolt and lock bolt. then remove

correct positions on the engine.
CAUTION:
. Use tender covels to avoid damaging painted sul-
faces.
o To avoid damage, unplug the wiling connectors
carefully while holding the connector portion to
avoid damage.
. To avoid damaging the cylinder head, wait until the
engine coolant temperature drops below 100"F
{38"C} before loossning the tetaining bolts.
NOTE:
o Mark all wiring and hoses to avoid misconnectlon
Also, be sure that they do not contact other wiring or
hoses, or interfere with other parts.

VALVESEAT
PFUSSIAN BTUE COMPOUNO
The actual valve seating surface. as shown by the
blue comDound, should be centered on the seat.
. lf it is too high (closer to the valve stem), you
must make a second cut with the 60'cutter to
move it down, then one more cut with the 45'
cutter to restore seat width,
. lf it is too low (closer to the vslve edge), you
must make a second cut with the 30" cutter to
move it uD, then one more cut with the 45'cutter
to restore seat width.
NOTE: The final cut should always be made with
the 45" cutter.
lnsert the intake and exhaust valves in the head and
measure the valve stem installed height.
Intake. Exhau3t Siem Installsd Height:
Standard (New): 53.17 - 53.6,4 mm
12.093 - 2.112 in)
Sorvice Limit: 53.89 mm (2.122 in)
lf the valve stem installed height is over the service
limit. reDlace the valve and recheck. lf its still over
the service limit, replace the cylinder head; the
valve seat in the head is too deep.

Use a hot plate or oven to evenly heat the cylinder
head to 300"F (150'C). Monitor the temperature with
a cooking thermometer.
CAUTION:
. Do not use a torch; it may warp the head.
Do not got the head hottel than 300"F (150"C1;
