CAUTION!
Mixing of coolants other than specified (non-
HOAT), may result in engine damage and decreased
corrosion protection. If a non-HOAT coolant is intro-
duced into the cooling system in an emergency, it
should be replaced with the specified coolant as
soon as possible.
Do not use plain water alone or alcohol base anti-
freeze products. Do not use additional rust inhibi-
tors or antirust products, as they may not be compat-
ible with the radiator coolant and may plug the
radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.
Adding Coolant
When adding coolant, or refilling the system, a minimum
solution of 50% recommended HOAT ethylene glycol
engine coolant (antifreeze) and distilled water should be
used. Use higher concentrations (not to exceed 70%) if
temperatures below34°F (37°C) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.
The use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:Mixing coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.

WARNING!
Never add coolant to the radiator when the engine is
overheated. Do not loosen or remove pressure cap to
cool overheated engine. The coolant is under pres-
sure and severe scalding could result.
Coolant Pressure Cap
The coolant pressure cap must be fully tightened to
prevent loss of coolant, and to insure that coolant will
return to the radiator from the coolant bottle.
The pressure cap should be inspected and cleaned if there
is any accumulation of foreign material on the sealing
surfaces.
WARNING!
The warning words “DO NOT OPEN HOT” on the
coolant pressure cap are a safety precaution. Heat
causes pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the pres-
sure cap when the system is hot or under pressure.
Coolant Level
The coolant bottle system provides a quick visual method
for determining that the coolant level is adequate. With
the engine idling, and warmed to normal operating
temperature,the level of the coolant on the overflow
bottle should be between the fluid level marks.Check
the coolant level whenever the hood is raised.
The radiator normally remains completely full, so there is
no need to remove the pressure cap except checking
coolant freeze point or replacement with new antifreeze

coolant. Your service attendant should be advised of this.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill.
Points To Remember
A. Do not overfill the coolant bottle.
B. Check coolant freeze point in the radiator and in the
coolant bottle. If antifreeze needs to be added, contents of
coolant bottle also must be protected against freezing.
C. If frequent coolant additions are required, or if the
level in the coolant bottle does not drop when the engine
cools, the cooling system should be pressure tested for
leaks.
D. Maintain a minimum coolant concentration of 50%
ethylene glycol and distilled water.E. Make sure that the radiator and coolant bottle over-
flow hoses are not kinked or obstructed.
F. Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean also.
G. The thermostat should not be changed for summer or
winter operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance.
Emission Related Components
Fuel System Hoses And Vapor/Vacuum Harnesses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasions, and excessive
swelling suggest deterioration of the rubber. Particular

MAINTENANCE SCHEDULES
There are two maintenance schedules that show the
requiredservice for your vehicle.
First is Schedule“B”. It is for vehicles that are operated
under the conditions that are listed below and at the
beginning of the schedule.
•Day or night temperatures are below 32° F (0° C).
•Stop and go driving.
•Extensive engine idling.
•Driving in dusty conditions.
•Short trips of less than 10 miles (16 km).
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90° F (32° C).
•Trailer towing.
•Taxi, police, or delivery service (commercial service).
•Off-road or desert operation.
•If equipped for and operating with E-85 (ethanol)
fuel.
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
NOTE:IfANYof these apply to you then change your
coolant every 102,000 miles (163 000 km) or 60 months,
whichever comes first and follow schedule “B” of the

Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
NOTE:Under no circumstances should oil change in-
tervals exceed 6000 miles (10 000 km) or 6 months
whichever comes first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
