NOTICE: Make sure the seacock is back in the ON position. If this
operation is skipped, the engine will overheat, failing the raw water
pump impeller and causing severe engine problems. Make sure that
the cap/lid has been installed correctly and has not pinched the sealing
o-ring. This will cause air to be introduced into the system and could
cause the raw water impeller to fail causing severe engine problems.
NOTICE: This is a critical function of routine maintenance. Even clean-
appearing waterways may have debris such as pine needles or moss
that can enter the cooling system and create a blockage. Failure to
perform this function can result in serious overheating of the engine.
Damage to the engine and/or transmission caused by overheating is not
covered by warranty. Always pay attention to your temperature gauge,
even if you are carefully performing this check. Failure of the raw water
impeller or blockage of the transmission cooler are frequent causes of
overheating.
NOTICE: If the serpentine belt comes off or wears through, catastrophic
engine failure may occur. Do not operate the engine without a properly
installed serpentine belt. Any resulting damage will not be covered by
the warranty.
NOTICE: Air in the system could cause the raw water impeller to fail,
causing severe engine problems. If air in the system is persistent, visit
your local Ilmor service center.
