From the water pump to the head gasket and radiator, the cooling system of the car is the heart of the engine. It should be inspected and maintained on a regular basis. By keeping all components of the cooling system running optimally, you can extend the life of the pistons, cylinders, valves and the entire engine block.

Have the radiator flushed according to the vehicle manufacturer's recommendations. This is done by draining the anti-freeze or coolant from the bottom of the radiator, flushing the core out with cold water from a garden hose and refilling the radiator with the proper fluid. A radiator flush prevents engine deposits and debris from gathering inside the radiator, which can cause overheating.
2Inspect all radiator hoses whenever you maintain the cooling system of a car. Hoses can leak when they become brittle, cracked or spongy when worn, or when bumps or bulges develop in the lining. It makes sense to carry a spare set of radiator hoses in your garage, since it's relatively easy to change the hoses throughout the cooling system.
3Check the water pump periodically for water stains on the pump housing or looseness in the shaft pulley. Water pumps usually fail by either developing cracks in the seals or by the bearings going bad, and you can prevent pump failure by inspecting these two features on a regular basis.
4Look inside the engine compartment, crankcase and radiator for a foamy beige residue or fluid. This fluid is caused by a mixture of oil and engine coolant, and may indicate a worn or cracked head gasket. The head gasket provides a seal between the crankcase and the engine block, and when damaged can cause the engine to heat up to the point where the pistons, valves and cylinders actually melt.
5Examine the entire cooling system of your car for any types of leaks. It's usually easy to spot brightly colored fluids such as anti-freeze and coolant, especially when they are bubbling, spraying or dripping onto your driveway.
