    I’m pretty sure the dinosaurs died out when they stopped gathering food and started having meetings to discuss gathering food

    A bookshop is one of the only pieces of evidence we have that people are still thinking

    I thought I had a stuffed fan for ages but it turned out to be the radiator.

    It was blocked right in the front of the fan where the higher temps are supposed to actuated the spring in the fan to let more fluid in & lock the fan.

    Consequently that area was cold while all around it was super hot & the fan never locked up.

    New radiator fixed it.

    Funny you say that.... Just talking with mechanic, my radiator looks to be original so we both agreed to replace it too.

    A good easy test goes like this:
    After a run, engine up to normal operating temp, let engine idle for 2-3 minutes, bonnet open, have someone switch engine off while you watch the fan, the fan should do less than 5 revolutions (preferably only 2 or 3) after the engine has stopped.
