Water pump solutions

[Ian Williams]

I had a 750cc Coventry Climax FWP Charles, that had a water pump very similar to an Imp but I found it difficult to make it work on a std seven. Keep the suggestions coming though, pictures of successful installations would be good, particularly if anyone has used kart pumps, they look promising but I do not have an example to mess about with at present.

You generally need a water pump when you try to make your engine produce more power, so the water pump is related to a chosen route of development and therefore should be somewhat period.
Old cars overheat in modern cities and traffic and that's not due to a wilful desire to go faster, merely a function of the congestion in the U.K., hence the tolerance for electric fans.

That's exactly it. When I had my perfectly standard spec P Type Lea Francis that had no water pump or mechanical fan it was impossible to take it out in modern town/city traffic without overheating. The electric fan I fitted enabled me to use the car as you would normally expect to. Friends living in central London with a vintage Alvis 12/50 similarly specified from new could only take it out on Sunday mornings as at any other time, the traffic congestion was such that it would overheat before they'd gone any distance at all. Again, an electric fan solved that. You just have to remember to turn them on before the engine overheats. Turning them on when things are boiling is too late and achieves all but nothing.

Thanks for the explanation Charles and Steve it now make's more sense to me why the VSCC would allow electric fans. I hate the way they look on a vintage car but can see there may be few other options in some situations.
