An automobile cooling
system is composed of several finely tuned machines. If a single
component does not function properly, the entire system suffers.
While overheating episodes are usually thought to be the fault of the
radiator, other components can contribute to the failure of the
radiator to properly disperse heat.
Failed Water Pump
Water pump failure is a
common reason for radiator malfunction. The water pump is responsible
for generating enough pressure to move the coolant-water-antifreeze
mixture from the radiator, through the hose, to the engine, and back
to the radiator. If the water pump fails, the heat generated by the
engine will continue to build until the entire vehicle overheats.
Broken Thermostat
An automobile thermostat
is responsible for controlling the amount of coolant-water-antifreeze
mixture that enters and exits a radiator. When the thermostat fails,
the amount of the mixture that flows into the radiator becomes
insufficient to keep up with the heat the engine generates.
Various Obstructions
Various obstructions can
impede the effectiveness of a radiator. If something gets caught
between it and the fan, for example, the path of the air becomes
obstructed. When that happens, the radiator runs out of air for
transferring the accumulated heat. A blocked radiator hose also
limits the flow of coolant-water-antifreeze, reducing the amount of
heat the mixture removes from the engine.
To avoid these problems,
be sure to have regular maintenance done on your cooling system.
