(4) Hold the nut and remove the mounting

through bolt.

(5) Remove the bolts retaining the mounting to

the transaxle and maneuver the mounting from the
engine compartment.

(6) If necessary remove the bolts retaining the

support bracket to the inner mudguard and withdraw
the support bracket.

Installation is a reversal of the removal procedure

ensuring that the weight of the engine is bearing on
the engine mounting before tightening the through
bolt securely.

TO RENEW RIGHT HAND SIDE MOUNTING

(1) Disconnect the negative battery terminal.
(2) On 1.8 liter models, remove the air cleaner

assembly. Refer to the Fuel and Engine Management
section if necessary.

(3) Support the engine under the sump using a

jack. Interpose a block of wood between the head of
the jack and the sump to prevent damage.

(4) Hold the nut and remove the mounting

through bolt and rubber.

(5) Remove the bolts retaining the mounting to

the inner mudguard and maneuver the mounting
from the engine compartment.

(6) If necessary, remove the nuts and bolts

retaining the support brackets to the engine assembly
and withdraw the support brackets.

Installation is a reversal of the removal procedure

ensuring that the weight of the engine is bearing on
the engine mounting before tightening the through
bolt securely.

TO RENEW FRONT TORQUE DAMPER

(1) Raise the front of the vehicle, remove the

splash guard fasteners and remove the splash guard(s)
from the front of the vehicle.

(2) Remove the through bolts and nuts from the

torque damper.

NOTE: It may be necessary to unclip the
wiring harness from the lower radiator sup-
port panel to gain access to the front through
bolt.

(3) Withdraw the torque damper from the

engine.

(4) If necessary the support brackets can be

removed.

Installation is a reversal of the removal procedure

ensuring that the arrow on the engine bracket faces
upwards.

TO RENEW REAR ENGINE MOUNTING AND
TORQUE DAMPER

Automatic and manual transaxle models both use

a similar rear engine mounting with different support
brackets. Manual transaxle models use a rear torque
damper.

(1) Raise the front of the vehicle and support it

on chassis stands.

(2) Remove the stabilizer bar mounting bracket

bolts and allow the rear of the stabilizer bar to hang
down slightly.

(3) Remove the nuts and bolts retaining the

engine crossmember to the vehicle underbody and

14. EXHAUST SYSTEM

TO REMOVE AND INSTAL

Engine Pipe

(1) Raise the front of the vehicle and support it

on chassis stands.

(2) Remove the nuts retaining the engine pipe to

the exhaust manifold flange.

NOTE: It is advisable to soak all exhaust
system nuts and bolts with penetrating oil to
prevent breakage when removing.

(3) Remove the bolts from the flexible joint and

withdraw the engine pipe from the vehicle. Discard
the gasket.

Installation is a reversal of the removal procedure

with attention to the following points:

(1) Clean any carbon build up from the exhaust

flange and pipe joints.

(2) Inspect the condition of the flexible joint

spring. Renew the engine pipe assembly if necessary.

(3) Use a new exhaust manifold flange gasket

and coat the manifold studs with anti-seize com-
pound.

(4) Ensure that all nuts and bolts are tightened

securely.

Rear System

(1) Raise the front and rear of the vehicle and

support it on chassis stands.

(2) Loosen the clamp securing the tailpipe and

muffler assembly to the rear pipe.

(3) Remove the mounting bolts and slide the

tailpipe and muffler assembly from the rear pipe.

NOTE; Should difficulty be experienced
when separating the exhaust pipes, they
may be cut with a hacksaw or pipe cutter if
a replacement system is to be installed.

If heat is used to loosen frozen joints take

extreme care near floor panels, fuel and
brake lines or electrical wiring.

(4) Remove the bolts from the intermediate pipe

and rear pipe mountings and lower the exhaust
system. Use care not to drop the catalytic converter.

(5) If necessary the catalytic converter can be

removed from the intermediate pipe and the rear pipe
assembly by removing the retaining bolts.

COOLANT LEAKAGE - EXTERNAL

(1) Loose hose clips or faulty hoses: Tighten the

hose clips or renew the faulty water hoses.

(2) Leaking radiator core or tanks: Repair or

renew the radiator.

(3) Leaking heater core or hoses: Repair or

renew the heater core. Check the hose clips and hoses
and renew if necessary.

(4) Leaks at the thermostat cover and/or water

pump O rings. Renew the O rings.

age by running the engine to operating
temperature over a dry floor and checking
for the leak source.

Check the vehicle interior below the

heater core for moisture. If a rusted welch
plug is found, it is a good practice to renew
all the welch plugs.

COOLANT LEAKAGE - INTERNAL
