Cooling Fans.

Fitting the fans with the mounting plates means drilling into the rad housing. Did check that there were no cooling cores behind cos it just didn't look right but all was clear. Not distrusting GD but the thought of drilling into a rad with a 5mm bit was a little worrying.

The fan plates have a thread welded in and they are a good fit. The fans have a little lip on the edges that I cut off to get them closer to each other. May cut off the outer edge ones too as they touch the side edge of the housing.
Also drilled and tapped the holes for the header thank into the top brace. There isn't much to tap into but the fixings only stop it from rattling about as the hoses hold it in place so a bit of thread lock it should hold fine.Next thing I have to work out is the wiring, as the feed in the loom is enough for one fan and two fans on a hot day could pop the fuse. So a separate feed and switched relay thingy will be needed for one fan.

Steve,

Both Fans work OK off the one feed.... even on a hot day ;-)

I have heard a couple of people recommend it as if the fuse does go, then no fans and I do plan a few hard track days. Thanks for the reassurance. I may suck it n see, worry about that after its on the road. ;-)
