NOTE: When routing speedometer cable, DO NOT bend cable sharply.
Minimum bending radius is 6" (150 mm). Speedometer cable
length varies with transmission type.

Disconnect speedometer cable from transmission or transaxle.
Remove instrument cluster from instrument panel. See
INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Disconnect
speedometer cable from instrument cluster and/or adapter (if
equipped). Remove speedometer cable from firewall grommet.
Installation
Install new cable. Insert cable until stopper seats properly
in groove on rear of speedometer housing. Pull speedometer cable
through firewall grommet until cable marking is visible from engine
compartment. Install adapter onto speedometer cable (if equipped).
Install instrument cluster. See INSTRUMENT CLUSTER under REMOVAL &
INSTALLATION. Install cable onto transmission or transaxle. Check for
proper operation.

TIMING BELT INTERFERENCE VERIFICATION INFORMATION
TIMING BELT INTERFERENCE CAUTION
NOTE: CAMSHAFT DRIVE BELTS OR TIMING BELTS - The condition of
camshaft drive belts should always be checked on vehicles
which have more than 50,000 miles. Although some
manufacturers do not recommend replacement at a specified
mileage, others require it at 60,000-100,000 miles. A
camshaft drive belt failure may cause extensive damage to
internal engine components on most engines, although some
designs do not allow piston-to-valve contact. These designs
are often called "Free Wheeling". Many manufacturers changed
their maintenance and warranty schedules in the mid-1980's to
reflect timing belt inspection and/or replacement at
50,000-60,000 miles. Most service interval schedules shown in
this section reflect these changes. Belts or components
should be inspected and replaced if any of the following
conditions exist:
* Crack Or Tears In Belt Surface
* Missing, Damaged, Cracked Or Rounded Teeth
* Oil Contamination
* Damaged Or Faulty Tensioners
* Incorrect Tension Adjustment

piston(s) or valve(s) if there has been a timing belt
failure.

specific scheduled maintenance interval, aftermarket
belt manufacturers suggest the belt be replaced at

CAMSHAFT TIMING BELT
CAUTION: Failure to replace a faulty camshaft timing belt may result
in serious engine damage.
The condition of camshaft drive belts should always be
checked on vehicles which have more than 50,000 miles. Although some
manufacturers do not recommend belt replacement at a specified
mileage, others require it at 60,000-100,000 miles. A camshaft drive
belt failure may cause extensive damage to internal engine components
on most engines, although some designs do not allow piston-to-valve
contact. These designs are often called "Free Wheeling".
Many manufacturers changed their maintenance and warranty
schedules in the mid-1980's to reflect timing belt inspection and/or

this manual reflect these changes.
Belts or components should be inspected and replaced if any
of the following conditions exist:
* Cracks Or Tears In Belt Surface
* Missing, Damaged, Cracked Or Rounded Teeth
* Oil Contamination
* Damaged Or Faulty Tensioners
* Incorrect Tension Adjustment
Replace camshaft timing belt at 60,000 mile intervals.
