Rexton 270xdi Cooling Fan Viscous Coupling

Found this from the net.
The units operation consists of two main parts
• The viscous coupling.
In the housing there is a wheel with fine grooves which runs in the also finely grooved housing to which the fan blades are attached. Between the housing and the wheel is silicone oil. Now a property of this oil is that it's viscosity is not so much depending on temperature (as with normal oil) but on velocity. The greater the oil velocity the greater the viscosity. The greater the difference in speed between the oil layer on the housing and the oil layer at the wheel the thicker the oil becomes and so the wheel (which is attached to the water pump shaft) takes the housing with it and the fan turns. As the fan speeds up the speed difference decreases and the silicone oil gets thinner....thus less driving force.....this system prevents the fan from over revving and limits it turning speed at about 2500 rpm
Another oil to check and change? Mine is a little tight, can check and compare during PG TT, remember ok?

Buy the oil for me too. I will get my mechanic to see if they can find the hole better. Must have some way to enter the oil or Rexton don't use oil to lubricate, self nature wet... hhehehehe

Tested my Fan is a bit tight, not sure if the oil needed to change or not. So, better stand by the oil to change if necessary.

Hi Bro,
Better call and order first b4 you come. If possible change the armature bearings together. Dun become like me, opening it so many times.
