I was going to make my own shroud for radiator fan(s) but then saw one 2nd hand on Trademe so bought that instead, not too bad, $100 for the shroud and two fans, they are $175 new. The wiring was a complete mess, they'd done the old twist and tape method. I'm not sure what kind of radiator it's actually for, I had to modify it a little bit to get it to fit and I think it's actually upside down compared to the way it was last mounted.
I spent all of yesterday mucking around with it and redoing the wiring, upgrading the wiring to the fan relay and fitting a fuse, I bled the cooling system and the good news is I refitted the silicone top hose and it doesn't leak! After replacing the fuse which either blew the first time the fans came on or was blown from the last time I used the fuse holder the fans were doing something really weird, only one was going but then it switched to the other one but it kept going even when the key was off, took me a while to realise I'd swapped the two relays that were next to each other, one was the relay for the headlights.
