Thankfully for the most part, the cooling situation on these if fairly straight forward and a known quantity, though there’s *always* some custom work to be done.
First thing’s first, the hoses. The upper hose can be made from a Dayco 72277 and a Dayco 72098, with a 12″ coupler between them, and the lower is a Dayco 71718. They’ll all be need to be lightly trimmed to fit, but they’ll get you most of the way there.
Of course, a 12″ coupler doesn’t seem to exist off the shelf, so I bought some aluminum tubing and a bead roller and got to work:
I made a strap out of a piece of tubing to secure the front of the upper radiator hose away from the front corner of the block, and the accessory belt idler pulley:
I’d been using a stock radiator for mock up so as to not risk dinging up the nice aluminum rad, but quickly found a clearance problem with the stock fan bolted on the thicker core aluminum rad, as it did not fit between the radiator and front sway bar.
With a slim-line fan ordered, I could get busy building mounts. I used the “through the core zip-tie” style ‘mounts’ it came with to secure it in place and give me something to aim at:
I cut the mounts out of steel plate. Aluminum *might* be strong enough for this (especially some CNC’d billet mounts), but this is critical enough that I’ll take the weight penalty for over-building it. I did turn up a set of spacers on the lathe out of aluminum, and the fan is bolting through weld nuts on the bottom of the mount plates
With the critical features of the lower mount done, the simpler top mount could be made:
A quick test fit shows PLENTY of room to the front sway bar:
Once all the critical fitup was done, less critical Speed Holes can be drilled:
A lick of paint and some foam-rubber insulation to seal the fan to the core, and prevent chafing:
