Default 1800E Electric fan

Hi all, am considering installing an electric fan on my 1970 1800E. Am going to call a company called Revotec, which advertises in Classic and Sportscar, but before being baffled by the experts, I'd really appreciate any wisdom members can pass on. Thanks very much!

Hi.
I fitted a Revotec fan to my 1800E.
Went with their high power 11" - 240mm blowing fan, mounted in front of the radiator using the universal fan brackets.
Didn't use their recommended fan controller utilising the bottom hose, instead bought the threaded fitting controller EPC M22 x 1.5mm external threat + EFC M22 brass boss, braised the boss onto the top of the radiator and fitted the controller there.
It appears to be working perfectly although the car's just been workshop run so far.
I could take some pictures if you like, going over there tomorrow.
David.

Total cost
Fan £77
Brackets £15
Threaded controller £65
Brass boss £9

sl; See my notes on ECF here: http://www.sw-em.com/Cooling_System....ic_cooling_fan

LJD; Top of Radiator is input side, and will be hot any time TStat is open and calling for cooling, so I expect your Fan to be running just about all the time...I prefer to only energize the ECF when Rad does not supply adequate cooling (hot outside air or slow roadspeed), therefore recommend placing temp sensor for ECF in bottom tank of Rad or Hose.

Cheers

exactly , so the fan will only come on when the radiator can no longer cope ..

however the Standard working mechanical Thermo viscous fan is best , it regulates it's self .

Guys not so I'm afraid.
In the early 80's the vehicle had a Kenlowe fan fitted with the thermostat mounted radiator top and the fan performed perfectly, just like the one in my Dad's Chrysler Avenger in fact.
Lemur, sorry for this confusion, hopefully this'll help, these are my experiments with the Revotec templates.
Pic 001 is the 10" fan template vertically mounted, 002 is the 11" horizontal.
David.
