Mechanical Technology: Engine Cooling System

The next inline part of the engine cooling system is the sea strainer. This is a device through which the raw water flows and is designed to filter out debris, sand, leaves, etc. before it gets to the engine. This device works much like a swimming pool skimmer. There are several kinds of strainers but all have a removable filter or screen which should be checked and cleaned or replaced on a regular basis.

Coolant leaks can occur anywhere in the cooling system. Nine out of ten times, coolant leaks are easy to find because the coolant can be seen dripping, spraying, seeping or bubbling from the leaky component. The first symptom of trouble is usually . But your car may also have a Low Coolant indicator lamp. If you suspect your vehicle has a coolant leak, open the hood and visually inspect the engine and cooling system for any sign of liquid leaking from the engine, radiator or hoses. The color of the coolant may be green, orange or yellow depending on the type of antifreeze in the system. You may also notice a sweet smell, which is a characteristic odor of ethylene glycol antifreeze.

    The performance requirements of antifreeze became more severe during the 1980's. The down sizing of vehicles to improve fuel economy meant extensive use of light materials such as aluminum and plastics for the construction of engine and cooling system parts.

    The engine cooling system is designed to help the engine maintain a particular operating temperature of between 205° F and 220° F (96°C - 104°C). When the system leaks or has some kind of mechanical failure it will allow the engine to run over the recommended temperature which can cause major engine damage such as:
