ENGINE
Description. The Chevrolet six cylinder valve-in-head truck
engines are the prime factor in Chevrolet's outstanding per-
formance and economy. They are designed to give long trouble-
free life. Chevrolet's four-way engine lubrication system pro-
vides the correct amount of lubrication
to
all moving parts.
Full stroke length water jackets, surrounding
all cylinders,
provide uniform cooling and prevent cylinder distortion which
would cause undue wear and poor oil economy.
The water passages
in
the cylinder block and cylinder head
properly direct the flow of water- to provide unifonn cooling of
the engine (fig. 25).
Care. The engine oil level should be checked each time fuel
is purchased and oil added when necessary. (See Lubrication
Section.) The engine should
be
inspected occasionally for oil
and water leaks and the necessary repairs made. Keep the
engine clean externally.
Valve Tappet Adjustment. Valve tappet adjustment should be
checked when the engine is thoroughly warmed
UP.
