Thermal switches
Provide reliable protection against engine
overheating while the vehicle is stationary:
thermal switches open or close the
electrical circuit, eg. on a cooling
fan, at a defined coolant
temperature.

The thermal switches from
MAHLE are designed for
an operating voltage of up
to 24V.

Oil thermostats
A transmission oil thermostat regulates the oil temperature in
an automatic transmission. This shortens the warm-up phase
considerably and the transmission is subsequently kept at an ideal
operating temperature.

The result: reduced wear, improved gearshift comfort and fuel
savings of approximately one percent in conventional driving
cycles.
No wear – yet important mainstays in the aftermarket
Although thermostats are not standard wearing parts, there is
considerable demand for spares.
Whether due to an accident or as part of repair or maintenance
work that requires access to the cooling system: these important
temperature regulators should be replaced at that time to ensure
continued functionality, because any loss of functionality or even
complete failure can have severe consequences.

If the thermostat is always open, the engine will be cooled too
much. If the thermostat is always closed, then the engine will not
be cooled at all and will overheat.

MAHLE’s latest range of


thermo-solutions keeps your


vehicle cooler under pressure


T


o operate effi ciently while minimising wear and emissions,
a combustion engine requires its temperature to remain
as constant as possible. Thermostats are used exactly for
that purpose, as it regulates the engine temperature with coolant.
MAHLE Aftermarket off ers customers not only an extensive range
of Behr Thermot-tronik thermostats, switches, and sensors
in original equipment quality, but is also the globally renowned
MAHLE Original brand.

Temperature managers – New in the MAHLE
Aftermarket product portfolio
A multitude of thermostats and other components for temperature
regulation are added to complete the MAHLE range.

Expansion Elements
The core of the thermostat: when heated, the expansion element
(wax) expands and thus moves the piston. If the temperature drops
again, it reduces in size, and a spring pushes the piston back into
its starting position.

Expansion elements are maintenance-free and durable. Its range
of use is very versatile: actuation forces from 30 N to 2 500 N,
short or long strokes, and a diversity of control ranges within the
temperature span of –20°C to +130°C.

Thermostat inserts
Precision at work: thermostat inserts enable the precise regulation
of coolant circuits to approximately 20m3/h in passenger cars,
commercial vehicles, stationary engines, agricultural and
construction machinery.

Housing thermostats
These can be fully connected with hoses or equipped with a fl ange
and hose connectors. What sets it apart is a consistent combination
of cover and housing, ie. the mixing chamber is already integrated.

Map-controlled thermostats
The most eff ective managers in the thermal system: Electrical
heating resistor is integrated in the operating element’s expansion
material. Consequently, these thermostats can be electrically
activated, and thereby have a considerably faster eff ect on the
engine temperature to keep the engine within the optimum range.

Sleeve valve thermostats
The workhorses: these regulate the cooling circuits in large engines
with fl ow volumes starting from approximately 20m3/h, eg. in large
passenger cars commercial vehicles, ships and locomotives.
The sleeve valve principle allows the axial relief of the thermal
expansion element, thus enabling precise regulation even under
heavy hydraulic loads – with a consistently high level of safety.

Repair shops not only need products in
original equipment quality—but data, too.

Quality is synonymous with holding to
a standard. The original equipment
standard, for instance.

The quality of a supplier is also measured
by the quality of the information that he
makes available to his partners.

To be well-positioned for the future, a repair shop requires
a partner who knows what it will need tomorrow and the day
after—because the partner’s range already includes it today.

In the right place at the right time.
Or how do you defi ne availability?

Support can be expected from a true
repair shop partner. Sales support.
