An efficient cooling system is very essential in order to protect the engine from overheating. Use good quality coolant for your car engine. The coolant level should be checked at least once a fortnight and preferably at more frequent intervals during summers.

Special attention should be given to the pressure cap over the radiator. When the coolant reaches very high temperature, it forces its way through a valve in the pressure cap and the overflow is then collected into coolant reservoir. When the engine is cool, the vacuum created in the radiator draws the overflow back. If the pressure cap is defective, the coolant evaporates through the pressure cap when it reaches high temperature, instead of flowing into the coolant reservoir. This reduces the level of coolant and can harm the engine.

Cooling system hoses should be checked regularly, especially before summer. Any hose that is cracked, and feels hard or spongy when squeezed should be replaced immediately. Ensure that the fan belt is working properly since it plays a vital part in cooling the engine. Get the cooling system serviced at the onset of the summer.
