Has anyone worked out a reliable method with easy to get brands to fit an L series with a thermo fan for the engine (the A/C already has one) instead of the viscous engine fan.
These things sound like a truck and yes, mine is spinning OK so the clutch is fine.
I am looking for hints re fitting, wiring and if fitted where to put a thermostat into the system.

Well if you fitted an electric fan that didn't run all the time like the std one does and developed cooling issues because of this would the noise seem so bad ?
For an electric fan to equal the performance of the std L one it woud have to run all the time - like the std one does . The whole std cooling system has been designed around a fan that runs all the time .
IMO the greatest problems Ls have radiator wise is that the core is reasonably wide but not very tall , most use a thin single tube core and it works significantly better if you can find a twin core rad .
Anyway in the end you'll find that "part time" fans are not the best idea with marginal radiators .

Good comments and logic. Thanks for that.
I was not aware of the L series cooling issues and I was thinking along the lines of my MY wagon which has 2 x electric fans. The main fan runs off a thermostat and the other only comes on with the A/C when it is on. This set up may be unique for the Touring wagon though. Thought I would copy this. The MY is on radiator number 3 or 4 with the last one straight off a Brumby. (I keep buying 2nd had ones so I cant expect much quality and/or life out of them) It does not have any cooling issues so this is why I was planning along these lines.
Something else I was reminded off. Back in the late 80's when I had a 77 LX Torana with a 308 V8 in it I fitted a flexible steel fan. The blades flexed to a basic straight, flat disc when the engine was reving but the blades bent back out to a standard fan blade at slower revs. It ran pretty quite too. Are these still around. I seem to remember these things were very dangerous and would cut fingers/hands/arms off if they came in contact but the design was very effective. In all if I have to live with the noise so be it.
