Cleaning the Engine
*
[SV05590(ALL)04/95]
A clean engine is more efficient because a
buildup of grease and dirt acts as an insulator,
keeping the engine warmer than usual.
*
[SV05592(ALL)07/95]
q
Extreme care must be used if a power washer
is used to clean the engine. The high pressure
fluid could penetrate sealed parts and
assemblies causing damage or malfunctions.
[SV05594(ALL)08/95]
q
In order to avoid possible cracking of the
engine block, do not spray a hot engine with
cold water.
[SV05596(ALL)06/95]
q
The alternator and air intake must be
covered. Covering these components will help
prevent water damage.
*
[SV05598(ALL)04/95]
q
Never wash or rinse the engine while it is
running. Water getting into the engine may
cause internal damage.

To replace and secure the fuel cap; place it in
position and rotate it clockwise until it clicks
(ratchets). Doing so will not damage or break
the fuel cap. The ratcheting mechanism allows
the fuel cap to be sealed without overtightening.
*
[SV06990(ALL)07/95]
If you lose the fuel cap, replace it with an
authorized Motorcraft or equivalent part.
%*
[SV07000(ALL)05/95]
RWARNING
If you do not use the proper fuel cap, the
pressure in the fuel tank can damage the
fuel system or cause it to work improperly
in a collision.
*
[SV07025(ALL)05/95]
NOTE: If you replace your fuel cap with an
aftermarket fuel filler cap, the customer
warranty may be void for any damage
to the fuel tank and/or fuel system.
*
[SV07050(ALL)05/95]
RWARNING
If the fuel cap is venting vapor or if you
hear a hissing sound, wait until it stops
before completely removing the cap.
*
[SV07060(ALL)11/89]
A venting fuel tank is not an abnormal
condition. It may be caused by:
*
[SV07061(ALL)07/95]
q
Too volatile a fuel for the weather conditions.
The service stations sometimes sell winter
grade fuel in the summer.
*
[SV07062(ALL)11/89]

Pulling a heavy load on hot days, or at high
altitudes.
*
