The pressurized coolant bottle (1) is mounted on top of the radiator. The coolant recovery/overflow bottle is made of high temperature plastic. The radiator overflow hose and the bypass hose connects to the top of bottle in order to help get trapped air out of the coolant system. Coolant is drawn back into the engine through the lower hose.
