Coolant Reservoir: Description and Operation
A "see-through" plastic reservoir, similar to the familiar windshield washer reservoir, is connected to the radiator by a hose. The recovery reservoir
collects coolant that expands with rising temperature and would otherwise overflow from the system. Coolant level should be at or above the "Cold',
mark on recovery reservoir, when system is cold.
