Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview
on page 6‑16for the
location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to a
dealer/retailer for service. Have it repaired as soon as
possible. You may also have the fluid level checked
by your dealer/retailer when the oil is changed. See
Recommended Fluids and Lubricants
on page 7‑10for
the proper fluid to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives fluid from the brake master
cylinder reservoir.
See Brakes
on page 6‑37for more information.
Cooling System
The Cooling System allows the engine to maintain the
correct working temperature.

Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
The coolant recovery tank
cap has this symbol on it.
The tank is located in the
engine compartment
toward the front of
the engine on the
passenger's side of
the vehicle.
See Engine Compartment Overview
on page 6‑16for
more information on location.
Check to see if coolant is visible in the coolant recovery
tank. If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down.
If coolant is visible but the coolant level is not at or
above the COLD FILL mark, add a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant at the
coolant recovery tank, but be sure the cooling system is
cool before this is done.
When the engine is cold, the coolant level should be at
the COLD FILL (A) line or a little higher. The COLD
FILL line is near the bottom of the tank and sticks out
from the rear of the tank.
When the engine is cold, the coolant level should be at
or above the COLD FILL line. If it is not, you may have
a leak in the cooling system.

7. Start the engine and let it run until you can feel theupper radiator hose getting hot. Watch out for the
engine cooling fan.
8. By this time, the coolant level inside the radiator filler port may be lower. If the level is lower, add
more of the proper DEX-COOL
®coolant mixture
through the fill port until the level reaches the base
of the fill port.
9. Then replace the pressure cap. At any time during this procedure, if coolant begins to flow out of the
fill port, reinstall the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
10. When the engine has cooled, check the coolant in the coolant recovery tank. The level in the coolant
recovery tank should be at the COLD FILL line
when the engine is cold.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
You will find a coolant temperature warning light and a
coolant temperature gauge on your vehicle's instrument
panel. See Engine Coolant Temperature Warning Light
on page 4‑34andEngine Coolant Temperature Gaugeon page 4‑34for more information.
You may decide not to lift the hood when this warning
appears, but instead get service help right away. See
Roadside Assistance Program on page 8‑6.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they are not, do not continue to run the
engine and have the vehicle serviced.
Notice: Engine damage from running the engine
without coolant is not covered by the warranty.
Notice: If the engine catches fire because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.

.Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system
must be repaired and the fluid level checked.

.Perform all services described in Maintenance I.
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps
and replacement, if needed.

.Body hinges and latches, key lock cylinders, and
rear compartment hinges lubrication. See

weatherstrips with a clean cloth makes them last
longer, seal better, and not stick or squeak.
