So, like most my AC pusher fan had sized solid so I decided to buy a nice little electric fan to replace it, with far less power consumption.

I went for this one at £23:
14" 12v Universal Electric Radiator/Intercooler Fan & Fitting Kit Push/Pull | eBay

I originally ordered a 14" version but it was too big, I removed the horizontal support bars which would have let me fit the bigger fan with a through-tie kit but i decided i wanted it mounting on the proper support bars, hence went for the smaller 12"

1. First job was to chop the Landrover connector off the old fan. I then used some heat shrink crimps to connect the new fan to the old connector

2. Next job is to open bonnet, remove three plastic plugs holding front grille. Remove old tie bars and fan assembly

3. I then rubbed down both the horizontal support bars and front diagonal tie rods - painted them with some hammerite and let dry for a day.

4. Next was to find some steel, I had some old shelving tie bars which were galvanised, lovely!
Put the horizontal tie bars back into the vehicle and measure the old fixing hole centres (mine were 10" apart on the horizontal and 12" on the verticle). I used these measurments to drill the holes on my new brackets.

bolt brackets in place:

5. Attach fan to new brackets using 6mm bolts and penny washers:

6. Once bolted in place you can use nanocom to strike up the fan to ensure it is pushing air onto radiator - nanocom only pulses it though so I ran the car with air con and heated up the front sensor to simulate a hot climate, fan then comes on:

7. Once the fan was tested I checked the fuse. The original was 40amp in my engine bay fuse box (F5 I think) since the new fan was a lot smaller and only pulled 80Watts I replaced with a 10amp fuse (80W/12v = 6.6amps)

8. Bolted everything up nice and tightly:

9. job done cup of tea :eek:)
I would allow a weekend for this as the first day you will be stribbing, rubbing down, painting your support bars and swapping over the electrical connector. Second day will be installing and checking everything.
