Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. 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.
SeeEngine Compartment Overview on page 332
for 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 you do
not do this, 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.
333

Engine Fan Noise
This vehicle has a clutched engine cooling fan.
When the clutch is engaged, the fan spins faster
to provide more air to cool the engine. In most
everyday driving conditions, the clutch is not
engaged. This improves fuel economy and reduces
fan noise. Under heavy vehicle loading, trailer
towing and/or high outside temperatures, the
fan speed increases when the clutch engages.
So you may hear an increase in fan noise.
This is normal and should not be mistaken as
the transmission slipping or making extra shifts.
It is merely the cooling system functioning
properly. The fan will slow down when additional
cooling is not required and the clutch disengages.
You may also hear this fan noise when you
start the engine. It will go away as the fan
clutch disengages.
Power Steering Fluid
The power steering uid
reservoir is located near
the front of the engine
compartment, behind
the radiator. SeeEngine
Compartment Overview
on page 332for
reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power
steering uid unless you suspect there is a leak
in the system or you hear an unusual noise.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired.
355

How to Check Power Steering Fluid
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the
reservoir clean.
3. Unscrew the cap and wipe the dipstick
with a clean rag.
4. Replace the cap and completely tighten it.
5. Then remove the cap again and look at
the uid level on the dipstick.
The level should be between the ADD and
FULL marks. If necessary, add only enough
uid to bring the level up to the proper range.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 452.
Always use the proper uid. Failure to use the
proper uid can cause leaks and damage hoses
and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure
to read the manufacturer’s instructions before
use. If you will be operating your vehicle in an area
where the temperature may fall below freezing,
use a uid that has sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 332
for reservoir location.
