What's in a cooling system?
Today's cooling systems are very sophisticated. The cooling system's primary function is to eliminate the waste heat produced by the engine and to maintain a safe operating temperature. Most vehicles today operate on a liquid cooling system. With this, system, the engine contains passages through which a liquid coolant (a solution of water and antifreeze) is circulated by a water pump which operates by the turning of the fan pulley by the fan belt. This circulating coolant absorbs heat created by the engine. The hot liquid is then passed through the radiator and cooler air is blown through it. A properly maintained water pump and its interrelated components always keep a fresh supply of cool coolant available and carries away the hot coolant to be cooled down in the radiator.
To ensure that your cooling system is working at an optimum, the coolant, engine coolant passages in the head and engine block, fans, radiators, heaters, drive belts, radiator and heater hoses, hose clamps, water pump, thermostat, radiator pressure cap, switches must all be checked regularly. Failure to maintain each and every one of these components can lead to the complete breakdown of your cooling system. All it takes is one weak spot anywhere in the system and over a short period of time your engine will be deprived of the liquid necessary to keep the engine at an ideal temperature. For an engine to run continuously without damage, the cooling system must be able to remove enough heat to keep the engine temperatures within a tolerable range.
There is one automotive part responsible for the constant regulation
of coolant temperature in the engine, and this important function rests
solely on the thermostat.
Standard thermostats (conventional type) operate continuously, adjusting the flow of coolant to maintain the engine's ideal operating temperature. During normal driving, the thermostat opens and closes to accommodate changes in operating temperatures. S long as the cooling system is in full operation the thermostat will continue to operate. However, if there an overheating condition and temperatures rise too high, above accepted levels , the heat generated by the engine will rapidly affect and destroy the thermostat pellet, thereby jamming the its mechanism into CLOSED position when overheated , preventing the continued flow of coolant between the radiator and the engine. This can lead to serious engine damage and costly repairs.
Automotive engines are solely dependent on the driver
It requires close attention to your car's operating system and the
ability to shut the engine down immediately when you sense danger. You
will have then to call a tow truck to take
New technology to keep things cool
The new Fail-Safe® thermostat offers advanced automotive technology and provide motorists with real added value and additional response time in the event of system overheating. This is the product of its kind in the automotive industry, developed for safe engine shut down in the case of system overheating.
Unlike standard thermostats, the Motorad Fail-Safe® thermostat, is built with an extra stroke that automatically locks into an open position when an overheating condition occurs. This allows the coolant to continue to flow between the radiator and engine, thereby protecting the engine components from serious damage while the vehicle is safely driven to the nearest service centre.
This major advancement in the automotive thermostat technology since the inception of the Fail-Safe® thermostat is one that promotes a measure of preventative maintenance for the engine in the cooling system. Although the thermostat is not designed to prevent system failure from overheating, it can greatly improve operating reliability in emergency situations. This translates into substantial cost savings for the driver where repairs are required and considerable comfort in the knowledge that when things heat up, you won't be caught on the side of the road with major automotive repair bills.
The operation of the Fail-Safe® thermostat can be likened to that of an automotive fuse in that it is designed to lock open in order to protect the engine from high temperatures.
Fail-Safe® thermostat gives you safe driving and Maximum protection
for your engine!
