E. Cam lubricant is sometimes included with a new camshaft. The
lubricant can help with breaking in the camshaft.
F. White lithium grease is a general-purpose lubricant available in a tube
or aerosol can. Uses of white lithium grease include hood hinges,
door hinges, cables, linkage, and shop equipment maintenance.
G. Stick lubricants are used on door strikers because they do not stain
clothes.
H. Some light-colored greases, such as white lithium grease, are not
compatible with ATF and should not be used as an assembly glue or
as a prelube for internal transmission parts.
CAUTION: If noncompatible grease is used during automatic
transmission assembly, components in the valve body of the
transmission can become stuck, resulting in shifting problems.
I. Dielectric grease, available in a tube, is used to seal electrical
connections to prevent voltage leakage and keep out dirt, corrosion,
and moisture.
J. Brake system silicone compound is a greaselike lubricant that comes
in a tube. It is used to lubricate sliders, rubber parts, or plastic parts
on brake systems.
III. Types and uses of specialty additives
A. Specialty additives include oil treatment, gas treatment, transmission
conditioner, and starting ether. Refer to the container label for hazard
warnings and handling procedures.
CAUTION: Wear PPE when working with specialty additives.
B. Oil treatments are used to raise motor oil viscosity or to free sticking
valves or lifters. Raising the motor oil viscosity can extend engine life
by increasing oil pressure.
NOTE: Adding too much oil treatment can result in poor lubricating
properties or oil that exceeds the proper viscosity, especially in cold
weather.
C. Gas treatment is used to help reduce moisture in gasoline and
eliminate buildup of carbon, gum, and varnish in fuel lines. Gas
treatment usually contains alcohol. Excessive amounts of methanol
can destroy rubber carburetor or fuel system components and damage
the lining of the fuel tank.
