Thank you Thomas, I can gladly source the above, but I heard someone somewhere on this forum mention it may interact with the lower radiator hose due to its size. Can anyone kindly confirm this?

....will ask my Guru!

The smaller ones can spin the fan enough to flex them into the radiator. I blew up two nice red fans and a black before wising up. So check your clearances.

A Very good point. Anyone else in favour of the 144mm over the 130mm?

Not only check the clearance between fan and radiator, also check/replace the engine rubber mountings.
If you are a hard braker (not heart breaker) you might consider installing these engine stoppers

Using the thin radiator with the proper hose we never faced any issues. Might be different if you install the big radiator with it's hose.

The "big" radiator is the AC car radiator?

As far as I can remember yours is the one shown in the middle. It mounts close to the front mask.
Whereas the early one on the left points too far towards the engine due to the shape of the top plate.
The right one shows an after market type.

ECS sells radiators that require extensive reworking to make them fit because of the top plate that TomHom discusses.
We had our radiators made with no overhang, we shim the rubber mounts by cutting and interlocking the serrations and we use the diesel fan with built in fan shroud that makes it impossible to get the fins jammed into the radiator. A broken fan blade is the least of your worries when it gets jammed in there and shatters and goes into the hood from below.
