Great, thanks for the info, did it matter what year the Mondeo was and what was the cooling performance like?
was from a mondeo made sometime after 2000, will easily cool a 308, you just need to set the on - off temp switch correctly so that the fans come on about switch off about 5'c above your thermostat temp eg
run a 180'F thermostat (82'c)
have the switch trigger the fans on at 92'c and off at say 85'c
if you google "temperature switches" theres an excellent thread in the toyota forums about it all
use good quality heavy wire and a single 30A relay for each fan.
let the switch operate the fans by triggering the relays instead of acting on the power circuit 12V otherwise you may burn the switch out. ie run the relay earths to the temp switch.
there's also a handy clip on the top of the fan shroud which you should leave on as it clips over the radiator lip allowing the fans to hang, mount it up with some trans cooler plastic mounting straps.
AU is too wide in early commodores, and the EL-EF will fit with a little work.
I know of a VK stroker in Brisbane that runs well with the mondeos without drama and considering Qld's weather thats pretty good.
