    Its the direction of the fan pulley not the crankshaft that determines which way you unscrew the fan hub. Serpentine belts can drive either way depending on the direction of wrap.

    Yes your correct. So start the motor and see which way the fan spins. Thats the way to undo it.

    Happy Days

    I made my spanner jaws at 36mm, for the 2.4 Puma. Length is 400mm. Pins for locating in pulley holes are 68mm apart.

    2.2 Puma pulley holding tool

    Here is a pic and a drawing of a pulley holder I made to help remove the fan.

    Its made from 40 by 10 mm flat bar. The two spigots are 15mm long and 9.8 mm diam. (3/8"). Just plug weld them into the holes

    If you print the drawing, on A4 to actual size, you can use it as a template, but check the critical dimensions

    issues with viscous fan again

    replace fan ass 6-7 weeks ago no problem after getting the old one off
    went for a drive over the week end and as usual check everything under bonnet before i go and found the the fan had come off .. ok so refit fan ass and started motor turn motor off and guess what fan spins off , refit again and gave the spanner a couple of extra hard hit with hammer hopefully that will stay on but is that the solution or should i be looking for another cause
    its a 110 td5 2002 model
    thanks
    hans
