CX500 C Custom 1981

The CX500 CB Cooling System :

The pressurised Cooling System consists of the Raditor, Water Pump, Thermostat, Camshaft driven Fan.

The Fan's RPM Runs at 1/2 the speed of the Engine RPM. So if the Engine RPM is running at 5000 RPM the Radiator Fans is at 2500 RPM. The system also comes with a Coolant Recover Tank.

​

The System uses a 11-15 psi (0.75-1.05 kg/cm-2) Radiator Cap. The system is designed to operate with a 180F or 82 degrees C. The Thermostat is located on top of the Cylinder Block just behind the Fan. The Centrifugal Vane Impeller Water Pump requires no particular Care and the components can be serviced.

 

Note though, if you are servicing or Inspecting the Water Pump Impeller yourself, the required Torque Wrench assembly is :  (6-9 ft-lb or 8-12 N.m)

​

It is important the the Coolant Level be kept to the FULL mark on the Coolant Recovery Tank.

​

Also Note : The Radiator Fan is situated on a Morse Tapered Chuck. The Front Axle on the CX500 can be used as a Puller Tool for dismantling the Fan from the Chuck in a Clockwise Rotation.

​

Also Note : When Re-Assembling the Fan, it is imperative to Note the Torque Wrench Settings when Re-Assembling Radiator Fan is in process. They are :

                                                                                                          (14-18 ft-lb or 19-24 N.m)

​

Coolant Change :

The Coolant should be completely drained and refilled with at least 50/50 mixture of Ethylene Glycol Antifreeze and Water every 33,600kms or every 2 years, whichever comes first.

​

CX500 Commuter and Mid Range Touring Machine.

The Cooling system has enabled the Machine to traverse through Heavy City Traffic commuting, enabling it to idles for very long periods at a constant Temperature. This effective ability has enabled it to reduce Vital Engine Wear that is predominantly associated with Air Cooled Machines.
