drain valves. One is located on
the front of the radiator core in

engine block. Both are easily
reached when the hood is open.
The underseat heater should be drained by
disconnecting both hose at the heater.

NOTE: When using an anti-freeze other than the above, follow the manufacturer's
directions. Kerosene, calcium chloride, sodium silicate, honey, sugar and like
materials are not satisfactory to use in the cooling system.
Anti-Freeze mixtures are expensive
so it is important not to lose them
through loose water connections.
Before putting them in your radi,
ator it is a good idea to have the
cylinder head gasket and hose
connections inspected and care-
fully tightened, or, if necessary,
replaced.
