Cleaning YOUR ENGINE : *Recommended by
professional ONLY!
Keeping an engine clean does more than to enhance
its appearance. Oil and fluid leaks will be easy to spot. A clean engine
will run cooler and is easier to repair and maintain.
Start your engine cleaning routine by putting a
plastic bag over the engine air intake. You may also want to protect
other parts from moisture, such as the distributor and electrical parts.
Aluminum foil often works where it is not possible to use a plastic bag.
Washing the engine is different from washing the
exterior of the car since the dirt and grease can be tougher to remove.
Making it easier is the fact that since most of the engine compartment
does not have a glossy finish, we don't have to worry about scratches.
For that reason, it is ok to rinse using high water pressure. You can
then go at it with liberal amounts of soap and water. Unlike the
exterior, it is ok to use common dishwashing detergent, since its grease
cutting abilities can make the job go faster. You should use a mitt or
sponge other than the one used on the car body however. If you've been
regularly cleaning your engine, then an application of soap and water
should do the trick. If grease and grime still remain, more drastic
steps may be required. Stronger cleaners or solvents will handle the
problem areas. A 50-50 mixture of kerosene and water will make a good
homebrew grease cutter. Some detailers report good results using liberal
amounts of WD-40. Let it soak for a while, then rinse thoroughly with a
hose or pressure washer. Simple Green is not recommended, as we've heard
reports of problems with certain kinds of metals. If necessary, use a
putty knife or paint brush, with its bristles cut short for stiffness,
to loosen the tough areas. SOS pads also work well on metal surfaces. A
toothbrush can be used to take care of detail areas. Dry using an
assortment of hand towels.
Battery corrosion and the battery box can best be
cleaned with a 50-50 mixture of water and baking soda. The towels or
rags used to clean the battery should not be used on any other part of
the car.
Dressings can be applied to plastic surfaces and
electrical insulation for a clean, new look. We don't recommend that you
attempt to clean a hot engine, since it is dangerous and some parts
could be damaged. We also hesitate to recommend steam cleaning. It can
do an impressive job on those engines that have years of grime on them,
but the process is harsh and can destroy valuable decals.
For a nice final touch, wash and wax the underside
of the hood. It'll set the engine off well and complete the job nicely.
