    No but he's a fan.

    IMHO removing the viscous fan is a mistake, it keeps a steady flow of air over the engine and prevents the thermal shock of an electric fan cycling on and off. IMHO many cases of fuel vaporisation are caused by fan removal. No doubt others will disagree.
    yup, agree. I removed my faulty viscous and ran for a year with a 16' Kenlowe. Since fitting a new viscous from Bob H the Kenlowe never comes on. Must be 5 years since fitting the new viscous coupling, I wouldn't be without it now!

    Ditto.

    And if you read the technical bulletin that details the tests done some years ago, the viscous fan was a massive part of the reason well maintained engines stay cool. Stuck in traffic temp gauge creeping up? More revs (to about 1500) simples.

    Mine came minus VC, has one now

    I agree with this, and when I fitted the kenlowe to mine I retained the mechanical fan.

    I think the viscous fan helps keep under bonnet temps down.
    I've only the viscous fan.
    When I bought her she only has a big kenlowe, however it didn't take long for me to fit the viscous fan back on, couldn't cope with the swinging temperature gauge!

    Yes, but it's in the attic - remove one point of failure - introduce another one! My mech hadn't realised that it was a ballasted coil (Mk2 wire in the loom type) and had used a pickup from the coil to feed the relays. It's a 2-speed and I think the Lo Speed relay must have dropped off whilst the Boost connection was still energised, causing the main power fuse to blow. Easily sorted.
