Figure 4-34 Radiator and water pump connections
WARNING: Make sure that all water transfer pipes are correctly installed into the fittings to
avoid leakages that can cause damage to the motor controller.
1. Install Water pump (23) to Water pump bracket (24).
2. Bond Water pump reducer (42) into position. If the pump has not been reworked, make
sure to remove the thicken part of the pump in and outlet.
WARNING: The radial tube on the water pump is the water outlet and the axial tube is the
water inlet. Connect water lines accordingly. The liquid cooling system will not
bleed properly and the cooling system will not function as intended otherwise.
3. Apply sealing tape to the threaded part of both fittings.
4. Install the Threaded elbow fitting (44) to the Radiator (22).
5. Install the threaded inline fitting (43) to the Water pump reducer (42).
6. Install Tee fitting (46) on water line from cold plate (48) and connect to Threaded inline
fitting (43).
7. Connect the rest of the piping system as shown in Figure 4-34 Radiator and water
pump connections.
Caution: Make sure not to have components pass the top of the Radiator (22) to allow
space for the propeller when the pylon system is retracted.
8. Fasten the No-spill fitting (45) and the Expansion cylinder Assembly (Figure 35) to the
Radiator support plate (20) with zip ties.
