*1: Always use Genuine Honda Manual Transmission Fluid (MTF). Using motor oil can cause stiffer shifting because itdoes not contain the proper addtuves.*2: Always use Genuine Honda Premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affectshift quality.*3: Always use Genuine Honda DOT 3 B.ake Fluid, Using a non-Honda brake fluid can cause corrosion and decrease thelife of the system.'4: Always use Genuine Honda Power Steering Fluid-V or S. Using any other type of power steering fluid or automatictransmission fluid can cause increase v,/ear and poor steering in cold weather.

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
Y AAA45-2A 1 /8" attachment).
!@@ When using this tool, as with any tool,
always use approved eye protection. Using the
fight tool tor each job helps increase productivity
while safeguarding tools, equipment and ihe user.
Turn the crankshaft so that the No. 1 and the No. 4pistons are at top dead center (TDC).
Remove the cylinder head cover.
Remove the distributor.
Loosen and disconnect the timinq belt from the
camshaft oullevs.
5. Remove the camshaft holder bolts, then remove the
camshaft holders, the camshafts and rocker arms.
Intake Valve Seals
6. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
7. Insert the cross shaft through the bottom hole of
the two uprights.
8.
9.
10.
Select the 7/8 in. diameter long compressor attach-
ment and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.
Position the piston at TDC and insen an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing springs
and removing the valve keepers.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown.
NOTE: Put shop towels over the oil passages toprevent the valve keepers from falling into the cylin-
der head.

lf you suspect a problem with the fuel pump, check that
the fuel pump actually runs; when it is ON, you will hear
some noise it you hold your ear to the fuel fill pon with
the fuel fill cap removed. The fuel pump should run for
two seconds, when ignition switch is first turned on. lf
the fuel pump does not make noise, check as followsl
