Cooling system

COOLING SYSTEM

PURPOSE

• To regulate engines internal temperature.• To remove excess heat from the engine.• To provide heat to the passenger

compartment.

TYPES OF COOLING SYSTEM

• Air cooling system

• Liquid cooling system

LIQUID COOLING SYSTEM

• An liquid cooling system is the collection of parts and substances (coolant) that work together to maintain the engine’s temperature at optimal level.

LIQUID COOLING SYSTEM

LIQUIDE COOLING SYSTEM PARTS

• Water pump• Radiator • Thermostat• Fan• Pressure cap• Hoses• Coolant

WATER PUMP

• A water pump is the simple device that will keep the coolant moving as long as engine is running

RADIATOR

• Radiator is used to cool the coolant delivered from the engine.

THERMOSTAT

• It is a valve which measures the temperature of the coolant.

• If the coolant is hot enough than its allow the coolant to flow and if the coolant is not hot than the flow is block.

THERMOSTAT

PRESSURE CAP

• It is a device which maintains the pressure in the cooling system up to certain point.

COOLANT

• It is the mixture of ethylene glycol and water the ratio is 50-50.
