and moisture free brake fluid. Never
reuse brake fluid. Keep containers and
reservoirs properly sealed.
Warning
Never put mineral based petroleum
oil into the brake system. Mineral oil
causes rubber parts in the system to
break down which could cause
complete brake failure.
Coolant
Coolant is a mixture of water and
antifreeze used to dissipate engine heat.
Ethylene glycol is the most common
form of antifreeze. Check the UV
Manufacturer’s recommendations when
selecting antifreeze. Most require one
specifically designed for aluminum
engines. There are types of antifreeze
have additives that inhibit corrosion.
Only mix antifreeze with distilled water.
Impurities in tap water may damage
internal cooling system passages.
Cleaners, Degreasers
and Solvents
Many chemicals are available to remove
oil, grease and other residue from the
UV. Before using cleaning solvents,
consider how they will be used and
disposed of, particularly if they are not
water-soluble. Local ordinances may
restrict types of cleaning chemicals.
Refer to Safety in this chapter. Use
brake parts cleaner for brake system
components. Brake parts cleaner leaves
no residue. Electrical contact cleaner is
a powerful solvent used to remove fuel
deposits and varnish from fuel system
components. Use this cleaner carefully,
as it may damage finishes. Most
solvents are designed to be used with a
parts washing cabinet for individual
component cleaning. For safety, use
only nonflammable or high flash point
solvents.
Gasket Sealant
Sealant is used in combination with a
gasket or seal. In other applications,
such as between crankcase halves, only
a sealant is used. Follow the
manufacturer’s recommendation when
using a sealant. Use extreme care when
choosing a different sealant based on its
resistance to heat, various fluids and its
sealing capabilities.
Gasket Remover
Aerosol gasket remover can help
remove stubborn gaskets. This product
can speed up the removal process and
prevent damage to the mating surface
that may be caused by using a scraping
tool. Most of these types of products are
very caustic. Follow the gasket remover
manufacturer’s instructions for use.
