(1) CAUT ION: T he condition of cam shaft tim ing belts should always be checked on vehicles which have m ore than
50,000 m iles. Although som e m anufacturers do not recom m end replacem ent at a specified m ileage,
others require it at 60,000-100,000 m iles. A cam shaft drive belt failure m ay cause extensive dam age to
internal engine com ponents on m ost engines, although som e designs do not allow piston-to-valve
contact. T hese designs are often called "Free Wheeling". Many m anufacturers changed their
m aintenance and warranty schedules in the m id-1980's to reflect tim ing belt inspection and/or
replacem ent at 50,000-60,000 m iles. Most service interval schedules shown in this section reflect these
changes. Belts or com ponents should be inspected and replaced if any of the following conditions
exist:

MAINTENANCE SERVICE INFORMATION
SEVERE & NORMAL SERVICE DEFINITIONS
Service is recommended at mileage intervals based on vehicle operation. Service schedules are based on the following primary operating
conditions:
Severe Service
Short Trips (About 10 Miles) In Freezing Temperatures
Towing Or Heavily Loaded
Severe Dust Conditions
Hot Weather, Stop-And-Go Driving
Extensive Idling Conditions (Taxi Or Delivery Type Service)
Normal Service
NOTE:For scheduled m aintenance intervals and the related fluid capacities, fluid specifications and labor
tim es for m ajor service intervals, see SCHEDULED SERVICES article in this section. Warranty
inform ation and specifications for fluid capacities, lubrication specifications, wheel and tire size, and
battery type are covered in this article.
NOTE:Use the Severe Service schedule if the vehicle to be serviced is operated under ANY (one or m ore) of
these conditions:

...

Driven More Than 10 Miles Daily
No Operating Conditions From Severe Service Schedule
CAMSHAFT TIMING BELT
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-va l ve
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 in 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 every 60,000 miles.
COOLING SYSTEM
Replace engine coolant every 36 months or 30,000 miles. Check condition of hoses and clamps every 12 months or 15,000 miles, whichever
comes first. Replace hoses and clamps if necessary.

SERVICE INTERVALS
Check fluid level at every engine oil change. Fluid, filter changes and band adjustments are not required under normal operation. Under severe
service operating conditions, change fluid every 30 months or 30,000 miles. Adjust band when fluid is changed.
CHECKING FLUID LEVEL
With transmission at normal operating temperature, place vehicle on level surface. Apply parking brake and run engine at idle. Run gearshift
lever through all positions, ending in Park. With engine running, fluid level should be between "F" and "L" marks. DO NOT overfill.
RECOMMENDED FLUID
Use Dexron-II ATF.

DRAINING & REFILLING
1. Remove undercover and side cover to gain access to transaxle oil pan. Remove drain plug and drain fluid. Remove oil pan and discard
gasket. Clean or replace filter screen as necessary. Tighten screen bolts to 71-97 INCH lbs. (8-11 N.m).
2. Install oil pan bolts. Tighten bolts to 44-71 INCH lbs. (5-8 N.m). On all models, install drain plug with NEW washer. Tighten plug to
29-40 ft. lbs. (39-54 N.m).
3. Install undercover and side cover. Add about 3 qts. of specified ATF through dipstick guide tube. DO NOT overfill. Run engine to
normal operating temperature and check fluid level.
