    Hi all,

    I'm after a new fan belt for my 240Z. The current one is labelled as a Nissan 11750-05E10KE and it measures 13mm x approx. 910mm (it may have stretched a little of course).

    Google tells me that equivalents include:

    BOSCH: 1987947654 = 13mm x 925mm
    CONTITECH: AVX13X900 = 13mm x 900mm
    GATES: 6466EXL = 13mm x 900mm
    GATES 6466MC = 13mm x 900mm
    DAYCO 13A0900C = 13mm x 900mm

    I guess any of these would be OK - although I don't know the difference between the 2 Gates belts.

    My belt is solid but some (all?) of the above are cogged. Is that a good or a bad thing? I assume a smooth belt is more of a period look?

    All advice welcomed! :)

    I think the cogged belts are more flexible and are better when fitted to smaller and/or similar sized pulleys, where they wrap around the circumference further

    a solid v belt is better when pulleys are larger and/or further apart, as in our old skool L series engines.... atleast that's what I've read!

    Ah, thanks for your reply :)

    In that case I will see if I can find a replacement which is solid...

    If anyone has a recommendation that would be great :)

    Looking at the spec, the working temperature on that belt is +80 degrees, on the majority of engines the normal operating temp is around +90

    It may be ok, since it is spinning round in free air and not touching the engine, but even so, it may not last anywhere near as long!

    Good point! Maybe not then. I'll keep looking :)
