there's some diagrams here that should help

also u say u can leave the fan running when u turn the engine off, the thermos will cool the water in the radiator in a minute or so but the water isnt circulating through the motor so isnt much help
best off running a davies craig mechanical temp switch or an electric one to turn them on automatically

I installed this manual switch tonight n works :)
but was just wondering when it open circuits the coolant temp sender to engage
the full speed fans,
the engine revs increase slighty, also sounded like it was running a bit rich too.
This was at idle but cruising, would this be a bit of a problem with fuel economy?

cheers
