ENGINE COOLANT – DIESEL VEHICLES

ENGINE COOLANT LEVEL CHECK

The coolant reserve tank (2) is located under the hood on the passenger side

(Figure 16)

. Raise the hood to

check the coolant level before every operation.

1. Check the coolant level of the reserve tank (2). If the coolant is at or below the LOW mark, add pre-mixed

coolant until the level reaches the FULL mark. If a leak is detected, have it checked by a trained techni-
cian.

See following WARNING.

WARNING

• Hot! Coolant reserve tank is pressurized. Do not remove cap when engine is hot.

AIR INTAKE SYSTEM

CAUT ION

• Do not drill into the driver-side frame. Failure to heed this caution could damage the engine by

allowing excessive contamination to enter the air intake system.

AIR FILTER REPLACEMENT

The air filter should be inspected periodically and replaced when necessary. Filter changes should not exceed
the recommended interval.

See Periodic Service Schedule on page 29.

More frequent service may be

required in extremely dirty operating environments. In the event of a loss of power, sluggish acceleration, or
a roughly running engine, service the air filter immediately.
