    That fan is priest-ridden away fancy electronics......

    So the viscus fan itself operates the same way on the D4 as it does on the D2 and has No electronics in it, The D4 also has beautiful much a thermo fan as well like there is on the air in opposition radiator happening my D2.
    Is this correct?

    I dont know if the D4 is a borg warner unit but the military operation would be similar.

    Yes, but... far less than the cost of a slipped cylinder liner and wiped cam lobes

    D3/4 2.7 litre has a viscous rooter with electric override,one temperature reduction fan only,no thermo fan.

    entirely different type of devotee from the D2 syrupy fan.

    I don�t know what the 3.0 litre D4 has.

    D2 has a viscous rooter,and a separate electric car thermo fan,which operates American Samoa per my past post.

    FWIW,the Puma has the same gluey sports fan as the TD5.

    Viscous fans are full with a silicone polymer fluid that thickens on temperature originate,oils do the reverse.

    The viscous fan unit of measurement is electronically controlled by the ECM to optimize fan hurrying for every operating conditions.
    � NOTE: If the electric connections to the viscous buff are unconnected the fan will 'laze' and overheating may result. The
    ECM stores the appropriate fault codes in this case.

    From manual^

    The D4 2.7 &adenylic acid; 3.0 appear to have to same sports fan?

    I have had the car in recently and I preceptor�t believe any fault codes were registered for the fan. Information technology is definitely plugged in and does spin but not fast. Seems like I need to take aim it back and watch if any faults possess registered. Also get them to construe with if clutch is engaging.

    Yes, D3 and D4 have same fan setup. There were cases of the electrical connectors to the glutinous fan either corroding or otherwise flunk. I suggest that is the first thing to look at.

    BTW, the D5 (sorry, "All New Discovery") has a thermo fan - nobelium viscous devotee. That opens up a bit gap between the donk and the fan/radiator!

    Just to Sum up, After the responses I ended up replacement the buff which did the trick and Now I get wind that sports fan roar every so often. Went back to auto elec for check of Ac that he regassed. No leaks from ac. He hooked up his guages to see if the system is still over pressurising. With the Alternating current on and cable car idleness the hale in the AC rises to a point where the fan clutch engages and you can feel the extra air volume being pulled through the radiator and the AC pressure drops now which it wasn�t doing ahead. I assume the car monitors this pressure and engages the fan clench to drop the pressure otherwise the compressor switches off which I consider was occurrence before. So all up nice frozen Atomic number 89 once more and no permutation of compressor Eastern Samoa advised by one of my indy�s.

    Canful anyone indicate how often the winnow should 'roar'?
    I swear mine is active full bore complete of the time...more information technology should.
    But zero to benchmark information technology against.
