Introduction
Aim instruments can measure and record the water temperature using a sensor (thermoresistor)
positioned in the pipe that goes from the radiator to the cylinder.
Installation notes
The water temperature sensor should be positioned inside the cylinder head: this sensor may be
used only with engines which accommodate the thermoresistor.
To install the water thermoresistor You just need to place it inside the screwed M10 hole located in
the cylinder head.
ATTENTION: While running the thermoresistor cable along the chassis, be careful to keep it as
far as possible from other cables (such as RPM or lap receiver cables) so to minimize interference
between them.
Aim suggests employment of our connection in sensor’s installation.
Inline water fitting (optional)
In the following drawing is represented the inline water fitting (optional), which is used to place
the water thermo resistor inside the pipe that goes from the radiator to the cylinder.
In order to firmly connect the fitting to the water pipe, Aim suggests You to use two wiring wraps.
