Can I just confirm that the fan in the photo which I pinched off this forum is indeed the wrong way round?
Cheers - Chris.

Re: 16 Blade fan orientation
The fan turns counter clockwise when at it from the back so it looks OK to me.

Re: 16 Blade fan orientation
Definitely wrong. The curve of the individual blades are engineered to be far more efficient the other way.

Re: 16 Blade fan orientation
Past Forum answers to this question suggested the rough side of any Fan should Face the Radiator .. i found that to be good advise

Re: 16 Blade fan orientation
Definitely the wrong direction. For one you would never be able to get the belt off with it like that.

Back to front 100%. My question is how did you get the rad in given that short amount of space?

Extreme Persistence....
I actually have no idea how I managed to get it in there, and everything done up. Seem to recall I was quite grumpy by the time I finished.
Needless to say, I had to take it out again. That was fun. If you wriggle your hands in, and undo every single fastener on the rad, shroud and brackets, you can lift the rad up just far enough to undo one fan bolt at a time, rotate and repeat. It took all day. I put it all back in with the fan the correct way round in under an hour.
Things I have learnt.
1. Save the nice double wire hose clips for where you can see them. Use a proper hex head jubilee for the bottom hose.
2. Make doubly sure you put the clip on so you can see the head / undo it from above.
3. Regardless of what anyone says, put something - silicone spray, grease, WD40, anything on the hose so it doesn’t weld itself to the spigot. I’d rather have the hose swell a bit, than have to take the rad out to dump the coolant.
4. The riveted / rough side of the fan goes TOWARDS the radiator.
The cause of all this was my engine overheating within minutes of startup. It’s been run up a handful of times, and I confirmed today with a test kit, that I have a head gasket failure.
Thanks all for confirming fan question.
