COOLING SYSTEM: Describes a type of system that removes heat from the engine. In a water-cooled engine, the system includes the radiator, pressure cap, fan, water pump, thermostat, water jackets; in an air-cooled engine, it consists of a fan, cooling fins and ducting.
ACCUMULATOR PISTON: Describes a unit found in a vehicle's automatic transmission designed to assist the servo in applying the brake band quickly and smoothly.
ANEROID-TYPE THERMOSTAT: Describes a type of thermostat located in the engine coolant system, prevalent in cars of the Fifties and Sixties; as the coolant in the engine reaches operating temperature, the volatile liquid in the bulb will boil and expand, closing the valve to allow coolant to the radiator.
BACK FLUSHING: Describes the circulation of water under pressure from the engine to the radiator (reversing the normal direction of flow) to clean the system more efficiently.
BAFFLE: Describes an obstruction used to slow down or divert the flow of gases, liquids or sound. Baffles can be found in a vehicle's fuel tank, crankcase, muffler, and radiator.
BLEED: Describes the procedure used to remove air bubbles from hydraulic lines and components of a system.
BLEEDING A COOLING SYSTEM: Describes the procedure of removing air bubbles from a cooling system so that they won't impede the flow of liquid through that system.
BLOCK HEATER: Describes a device that, during freezing weather, keeps the engine warm when the vehicle is not in use, making for an easier cold start. Especially important for starting diesel engines at exceptionally low temperatures.
COOLANT: Describes a type of liquid in the cooling system, usually a mixture of water and antifreeze (ethylene glycol). This mixture lowers the water's freezing point in the cooling system, prevents rust and corrosion, lubricates the water pump, picks up heat from the engine, and transfers it to the air passing through the radiator.
COOLANT RECOVERY SYSTEM: Describes a type of small bottle that acts as a reservoir for liquid expelled from the cooling system through the overflow pipe and returns the fluid to the system when it cools down.
COOLANT TEMPERATURE SENSOR: Describes a type of sensor located at the bottom of the radiator connected to the temperature gauge that prevents a vacuum from reaching a component until coolant temperature reaches a specific value.
COOLING FAN: Describes a large fan designed to suck relatively cool air and force it onto a warm object like an engine.
CORE SUPPORT: Describes the framework that supports the radiator and air conditioner condenser assembly and serves as the attaching point for the front fenders and grille assembly.
CROSSFLOW RADIATOR: Describes a type of radiator where the water flows sideways instead of vertically and which is, therefore, wider than it is high, permitting a lower hood line.
