It is very important to use good quality heat
resistant hose and fittings. Therefore, it is
strongly advised to use WhisperPower
installation kits.

HOW AND WHERE TO MOUNT THE RADIATOR
The radiator kit includes rubber mountings to prevent
vibrations to be transferred to the body of the vehicle
(figure 15). Due to the difference between vehicles general
instructions are not available. One has to find out where
the best place for mounting is. For OEM customers
WhisperPower
can
supply
a
special
customised
installation kit.

Bottom mounted radiator
When bottom mounted the radiator should not be the
lowest point of the vehicle to avoid damage.
A free flow of air should be guaranteed. When horizontal
mounted, the fan should be on top, which causes a flow of
air downwards. Often it is possible to find a place where
extra space above the fan helps to create a free flow of air.
It is recommended to make a shield below the radiator to
catch stones and dirt and operates as a spoiler. The
distance between the radiator and the shield should be at
least 50 mm. Sometimes it is possible to build the radiator
and shield on a sub frame that is mounted below the
vehicle as a module.
Measures have to be taken to prevent the hot
air circulating and reducing the capacity of the
radiator. Refer to figure 16

an optimal flow of air through the radiator
Side mounted radiator
Most effective and easy is to mount the radiator in the side
of the vehicle, if possible below the level of the top of the
engine. A louvered grid should protect the radiator from
rain and objects, but must not block the airflow. The fan
should be inwards which causes the air to blow outwards.
A disadvantage of having the radiator in the side is
possibly more noise of the electric fan and a flow of air that
could be felt by people passing by.
A free flow of air should be guaranteed. The ventilation
connection of the cooling system that goes to the
expansion tank, should be in the outgoing coolant flow on
top of the radiator.
