Checking Coolant
When your engine is cold, the coolant level should be at
the
FULL COLD mark or a little higher. When your
engine is
warm, the level should be up to the FULL
HOT mark or a little higher.

Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture ut the coolant recovery tank, but be
careful not to spill it.

Your radiator cap is a 15 psi (105 Wa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should be
performed at least twice a year (for instance, each spring
and fall). You should let your dealer’s service department
or other qualified service center do these jobs. Make
sure
any necessary repairs are completed at once.
Proper procedures to perform these services may be
found
in a service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering system
for damaged, loose or missing parts, signs of wear or lack
of lubrication. Inspect the power steering lines and hoses
for proper hook-up, binding, leaks,
cracks, chafing, etc.
Clean and then inspect the drive axle boot seals for
damage, tears or leakage. Replace seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body near
the exhaust system. Look for broken, damaged,
missing or
out-of-position parts
as well as open seams, holes, loose
connections or other conditions which could cause a
heat
build-up in the floor pan or could let exhaust fumes intw
the vehicle. See “Engine Exhaust” in the Index.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes, fittings
and clamps; replace as needed. Clean the outside of the
radiator and
air conditioning condenser. To help ensure
proper operation, a pressure test of the cooling system and
pressure cap is recommended at least once a year.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing
parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear.
Do not lubricate accelerator and
cruise control cables.
