COOLANT RESERVOIR TANK
A "see-through" plastic reservoir tank is connected to the radiator
by a hose. As the vehicle is driven, the coolant is heated and ex-
pands. The portion of the coolant displaced by this expansion flows
from the radiator into the reservoir tank.
When the vehicle is stopped and the coolant cools and contracts,
the displaced coolant is drawn back into the radiator by vacuum.
Thus, the radiator is kept filled with coolant to the desired level at
all times, resulting in increased cooling efficiency.
Coolant level should be between "FULL" and "LOW" marks on the
reservoir tank.
Coolant should be added only to the reservoir tank as necessary.
NOTE:
D Be sure to check cap gasket is located as shown in the fig-
