I have thermo fans on all my V12's, and have so since about 1995ish.
I use the Australian Ford Falcon twin thermo fan pack.
They basically slide straight in, after 2 side lugs are removed with a hacksaw.
I wire the LH fan to the a/c circuit, and the RH is thermo controlled using the existing thermo switch in the water pump inlet spout.
A friend fitted the same fans to his 1990 in Manila. He had them shipped via the seller on ?bay. No concerns when I last spoke with him.
Your market has items we dont know anything about, so people in your area will be better informed than me down here.
Basically any late model car has a very efficient thermo fan setup, and the fitting is where the imagination kicks in.
You wanted straight forward, well that is not always possible, but as I said, I use the Falcon fans with great success, and I consider them EASY to fit.
Here is a snap found via "google" and I hope it works.
Was reading your post (May 2016) reference Ford Falcon twin turbo fan conversion for XJS V12. and thinking to do this on my cabriolet.
Would appreciate it if you could give me the year and model Falcon you used. There seems to be a lot of variation throw up on a google search.
Your picture seems to show the two fans parallel to each other, but most of the fans I have seen offered for Falcons appear to have one fan slightly higher than the other on the mounting frame.
The "....pretty much drops in without trouble" is what you're paying for, mostly. That is, someone has already done all the experimenting and fabricating for a good fit.
Before buying from any vendor ask if they actually have product in stock and ready to ship. There is at least one, maybe a couple, who apparently wait several weeks till they have xxx-number of paid orders and then have the parts made up, assembled, and shipped

I purchased these and within 4000 miles both fans started squeaking, they had no brand on them so I assume they were the $20 variety, I have since replaced with spal fans, this and his poor feedback, but the plate that support for the fans is good, if only they sold separately, it would be the way to go.
p.s. you can change the crank seal I 1 hour with these fans fitted and possible the water pump on a v12
I replaced the smaller fan with a: Maradyne Champion Series M103K - 10 inch 130W - 950 CFM Works great - after linishing the outside for a perfect fit. Nice and close.

OK, looooong time ago.
I used the latest model Falcon on the market at the time, so 1996/96 would be EF I reckon.
I got the "taxi pack" spec fan from a mate at the Ford Dealer.
They had Bosch Germany stickies on both motors, so I reckon good enough for the Jag, no idea what is out there these days. Others I have converted have supplied the fan pack in a Ford box, and I did not look.
This is the EF fan snap, NOT mine, simply one I found on the Net.
Many cars have Efans now, and maybe there is something better out there, dunno. Outside the box thinking is always good and fun.
Hi Grant,
I am in Melbourne and have just bought Ford Falcon twin fans to fit onto my 1986 XJSC as it has the dreaded yellow fan with cracks in it and the viscous coupling is leaking oil. I noticed that one fan has two wires - simple, but the other one has 3 wires - why? Would you have a wiring diagram for connecting them to the Jaguar? I don't want to make a mistake. Also in your set up, if the A/C is not on, would only one fan work? Thanks in advance.

l have falcon twins on my xjrs and as l recall one fan is two speed unit and one is on or off.
I don't have my original circuit scribble to hand but l think l wired for low speed fan on with A/C and both fans full power switched by temp switch.

I fitted the Falcon dual fan setup 20 years ago in my 79 coupe after changing the engine to a rebuilt HE with electric coolant pump.
There is a non OEM full engine fuel/ignition system on the car and that I used to control the fans thru relays.
The fans are driven at full speed when the engine is over 1200RPM and/or hot.
Otherwise they are driven at low speed.
I had one problem fitting the fan shroud, it slightly fouled the return oil pipe low down on the LHS of the radiator.
Since there was a mechanic across the road at work who was a better welder than me, I hacksawed a cut in the pipe so I could bend it slightly and he welded it up for free.
Problem fixed but not sure why others do not seem to have that pipe problem.
This diagram may help. I used Ford Falcon EL twin fans, fit very easy. I also used a thermo switch with hi and lo settings, you need to add relays, takes a while but very worth it. Please ignore the D* line. Useful link here https://vasa.org.au/wp-content/rtp/v.../RTPELV1B4.pdf
Can post pictures if needed

Not sure if it would have made a difference in your case but l installed mine upside down (see pic in post #11) It fitted my radiator perfectly (this was an aluminium radiator) and may have had the effect of creating a little more clearance at the bottom.
l don't know if full flow verses bypass flow oil cooling would make any difference to pipe clearances maybe.
