Mazda Thermostat
The Mazda thermostat is the device in your vehicle’s cooling system that regulates
the temperature of the engine system, setting it always at a manageable setpoint
temperature. It is basically the cooling system’s temperature regulator. This
works by controlling the flow of heat energy into and out of the system. The engine
can produce a massive amount of heat during its combustion operations. Excessive
heat can cause grave damage to the engine as well as its internal working parts.
For this reason that the cooling system is employed to dissipate one-third of
the heat and keep the engine constantly at a desirable temperature, allowing it
to perform at its peak.
The engine in your vehicle runs at its best fairly at a high temperature. When
the engine is cold, it is less efficient, emits more pollution, and its high precision
internal parts wear out rapidly. So in order for the engine to heat up as fast
as possible, and keep it at a stable temperature, the Mazda thermostats will do
the job. It works by regulating the amount of water that passes through the radiator.
At low temperatures, the outlet to the radiator is shut closed so that all coolant
is recirculated back through the engine. Once the temperature of the coolant rises
between 180F and 195F (82-91C), the thermostat gradually opens, permitting the
fluid to flow through the radiator. When the coolant reaches 200F to 218F (93-103C),
the thermostat completely opens, dispersing the heat from the engine.
A typical thermostat is made with an outer body that houses a temperature-sensitive
valve that opens and closes depending on the coolant temperature. Some vehicles
use computer controlled thermostats that are controlled via the powertrain control
module (PCM). Usually thermostats are located between the radiator and the engine.
The key device behind an efficient thermostat function is the small cylinder mounted
on the engine-side. This cylinder is filled with wax and usually starts to melt
whenever the temperature is hitting at around 180F. A connecting rod to the valve
presses into this wax. As the wax melts, it expands and causes the rod to be pushed
out of the cylinder and opens the valve.
The Mazda thermostat is a critical part of the cooling system and its failure
can pose various symptoms and problems. A defective thermostat can result to low
heater output, overheating, increased fuel consumption, knocking or pinging, and
low temperature gauge readings. Also, a failed emission test can also be attributed
to a faulty thermostat. To determine if your vheicle’s thermostat is properly
working, have the cooling system thoroughly inspected by a qualified service technician.
When damage is evident, have it replaced at once.
The best way of preserving the life and consistency of the Mazda thermostat is
by giving its regular check-up and maintenance. A faulty thermostat should be
replaced to avoid further cooling system problems as well as inconveniences. You
