•
Engine coolant concentrations below 40% will decrease the
freeze protection characteristics of the engine coolant and may
cause engine damage.
•
If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
FUEL FILTER/WATER SEPARATOR
Your vehicle is equipped with two fuel filters; one is mounted on top of
the engine, the second one is mounted inside the Horizontal Fuel
Conditioner Module (HFCM) on the inside of the left frame rail by the
transmission. The fuel filter/water separator removes any contaminated
particles and/or water from the fuel before the fuel enters the engine.
The fuel filter/water separator should be drained as recommended in the
scheduled maintenance information.
Draining the fuel filter/water separator
Water should be drained from the
module assembly whenever the
warning light comes on or every
5,000 miles (8,000 km). The WATER
IN FUEL light will come on when approximately 0.13 pints (60 cc) of
water accumulates in the module.
1. Stop the vehicle and
shut off
the engine.
WARNING:
The vehicle must be stopped with the engine off
when draining the HFCM. Fuel may ignite if separator is drained
while the engine is running or vehicle is moving.
2. Locate the module drain plug cap
on the outside of the left frame rail
and place an appropriate container
under the drain plug.
3. Loosen the drain plug by turning it counterclockwise. Allow to drain
for approximately 25 seconds or until clean fuel is observed. Install the
drain plug by turning it clockwise until it is firmly seated.
