well i'm running twin leccy fans, which have only ever come on about 3 times EVER to my knowledge... lol car's never got hot enuf for them to come on! only time they ever come on is when its really hot n cars left idling for AGES
as far as the pipework's concerned, it all appears to be plumbed in ok...
foreign, yes it uses a lot of fuel (even now its its running on closed loop!)
my radiator is significantly larger than a standard 24v granny radiator, but i wouldnt have thought that'd matter as long as the thermostat was working ok...
