INSTALLATION
Fig.17. Low profile radiator assembly on the roof
Most cooling problems originate from air
traps blocking the circulation of the engine
coolant.
It is very important to use good quality heat
resistant hose and fittings. Therefore it is
strongly advised to use Mastervolt
installation kits.
2 How and where to mount the radiators
The radiator kit includes rubber mountings to prevent
vibrations to be transferred to the body of the vehicle (fig.
18). 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
Mastervolt can supply a special customised installation
kit.

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, that 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 radiators and shield on a sub frame that is
mounted below the vehicle as a module.
Measures has to be taken to prevent the
hot air circulating and reducing the
capacity of the radiators. Refer to figure.19

optimal flow of air through the radiators.
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 free flow of air should be guaranteed. The
ventilation (connection to the expansion tank) should be
in the outgoing flow on top of the radiator.
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.
Fig.21.
The radiators on the roof is often the best option from the
point of view of keeping the noise of the fans away from
people and it give the best result in dissipating the heat.
However often this option conflicts with the possible need
to keep the vehicle as low as possible. An other
disadvantage is that the piping has to go through the roof
