Towing
rl
It the car needs to be towed, call a professional towingservice. Never tow the car behind another car with just
a rope or chain. lt is very dange.ous.
Emergency Towing
There are three popular methods of towing a car:
Flat-bed Equipmont-The operator loads the car on theback of a truck. This is the best way of transporting thecar.
Whsol Lift Equipment-The tow truck uses two oivot-ing arms that go under the tires (front or rear) and liftsthem otf the ground. The other two wheels remain onthe ground.
Sling-type Equipmont-The tow truck uses metal cableswith hooks on the ends. These hooks go around partsof the frame or suspension and the cables lift that endof the car off the ground. The car's suspension and bodvcan be seriously damaged if this method of towing is at-tempted.
It the car cannot be transponed by flat-bed, it should betowed with the tfont wheels oft the ground. lf due todamage. the car must be towed with the front wheelson the ground, do the tollowing:
Manual Transmission
a Release the parking brake,a Shift the transmission to Neutral.
Automatic Transmission
a Release the parking brake.a Start the engine.
a Shift to @ oosition, then to S position.
a Turn off the engine.
NOTICE: lmproper towing preparation will damage thetransmission. Follow the above procedure exactly. lf you
cannot shift the transmission or stan the engine (auto-
matic transmission), your car must be transDorted on aflat-bed.
a lt is best to tow the car no tarther than SO miles lgokm). and keep the speed below 3b mph (bE km/h).
NOTICE: Trying to litt or tow your car by the bumperswill cause serious damage. The bumpers are not designedto support the car's weight.

Valve Clearance
Adjustment
NOTE:
. Valves should be adjusted cold; at a cylinder head
temperature of less than 100'F (38"C).
Adjustment is the same for both intake and exhaust
valves.
. After adjusting, retorque the crankshaft pulley bolt to
177 N.m (18.0 kgim, 130 lbf.ft).
1. Remove cylinder head cover.
ADJUSTING SCREW LOCATIONS:
2. Set the No. 1 piston at top dead center (TDC) (see
page 6-12). "UP" mark on the pulley should be at
the top, and the TDC grooves on the pulley should
align with the TDC groove on timing belt back
cover. TDC mark (painted white) on the crankshaft
pulley should align with pointer on the timing belt
tower cover.

Inspection
Loosen the adjusting screws.
Remove the camshaft holders and the rocker arms
NOTE: Mark the rocker arms before removing
them.
Reinstall the camshaft and holders. Tighten the
camshaft holder bolts in a crisscross pattern, begin-
ning with the inner bolts.
9.8 N.m (1.0 kgf.m,7.2 lbf.ft)
Seat the camshafts by pushing them toward the dis-
tributor end of the head with a screwdriver.
Zero the dial indicator against the end of the
camshaft. push the camshaft back and forth and
read the end play.
Camshalt End Play:
St.ndard lNow): 0.05 - 0.15 mm

Seivice Limit: 0.5 mm {0,02 in)
Remove the camshaft holder bolts from the cylinder
head.
NOTE: Unscrew the camshaft holder bolts two
turns at a time, in a crisscross pattern.
Lift the camshafts out ot the cylinder head. wipe
them clean, then inspect the lift ramps. Replace the
camshaft if any lobes are pitted, scored, or exces-
srvely worm
Clean the camshaft journal surfaces in the cylinder
head, then set the camshaft back in place. Insert a
plastigage strip across each iournal.
Install the camshaft holders and torque the bolts to
the values and in the sequence shown on page 6-30.
NOTE: Do not rotate camshafts during inspection.

11. lf camshaft-to-holder oil clearance is out of toler
ance:
. And the camshaft has already been replaced,
vou must replace the cylinder head.
. lf the camshaft has not been replaced, first check
total runout with the camshaft supported on V-
blocks.

- lf the total runout of the camshafts is within tol-
erance, replace the cylinder head.
- lf the total runout is out of tolerance, replace the
camshafts and recheck. lf the oil clearance is still
out of tolerance. replace the cylinder head.

Select the proper replacement guides and chill
them in the freezer section of a refrigerator for
about an hour.
Use a hot plate or oven to evenly heat the cylinder

18. When installing the cylinder head cover, hold the
rubber seal in the groove by placing your fingers on
the camshaft contacting surfaces (top of the semi-
circles).
Once the cvlinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the rubber seal.

. Before installing the cylinder head cover, clean
the cylinder head contacting surfaces using a
shop towel.
. Do not touch the pans where liquid gasket was
