DIY external resistor fix for fan problem on a Bora

[Rybky]

Has anyone with a Bora done the DIY external resistor fix for their fans? If you have, where did you mount the resistors?

The instructions are based on fitting to a golf and suggest putting the resistors on a plate mounted under the left headlight but looking at my Bora there does not seem to be any room to mount anything around there!

OK so the Bora has the same mounting point available as the Golf, it confused me because the photo of the mounting point is taken from under the car pointing up, so the plate is mounted horizontally! I thought it was vertical.

Hopefully getting the plate made up tomorrow and fitting on Sat.

Fix implemented and working well!

One strange thing, I connector the first resistor to one of the fan (not sure which one), did not cut the red/white wire though, just spliced in to it. Tried the car and both fans were happily spinning at low speed! So I cut the red/white wire after the splice, no change, both still work. Now I was not sure whether to attach the second resistor or not! I thought while I was there and everything was in place I might we well, the first thing I did was connect up just the red/white wire on the second fan and cut it, did not connect the red/black so in theory that fan should not be working at all ..... but still both fans are working!! WTF??

Anyway, completed the connections and still both fans now operate at low speed, have not seen them run at high speed yet, hopefully they can!

So if anyone needs some help with this mod let me know, it is not too hard, took me about 2 hours which included drilling the mounting plate and getting it fitting correctly.

I am trying to find the time to do this mod to my Bora

I have the resistors but still need to arrange a plate

who did you get to make the plate up? or did you do it yourself

I also have removed the headlights buy couldnt figure out where the plate mounts. Is it under the drivers or passengers side headlight?

Also whereabouts did you tap into the wiring. I can't see where the fan loom is.

Thanks for you help

I went to a local Aluminium fabrication place and they cut the plate out for me for $15, I just had to drill the holes. Note that one of the holes in the instructions is not in the correct place (or I measured it wrong!) plus I also changed the design slightly and had the top two corners cut off (where the outer holes are) as these holes were just to clear some bolts. Hope that makes sense!

To do this you need to get the car up on ramps or on axle stands, remove the plastic engine guards from underneath and then lay down under the left headlight and look up, the mounting point is under the headlight and is horizontal. You won't see this from above or even if the headlight is removed. The wires you need are right down at the bottom left of the fans, really easy to see and get to from underneath.

For mounting the plate I first put a bolt through the hole from above and then tightened on a nut with spring washer (or a nyloc nut would be better) so that I made a mounting stud, then I could just push the plate over the studs and add another nut and washer. There would be no way to access the back of the bolt to tighten it once the plate is in place otherwise.

Are you following the instructions on the web page where there are photos and a technical drawing for the plate? Sorry don't have the link to hand. If you are then when you get the splash guards up and look up the photos will suddenly make a lot more sense!!

Hope that helps, let me know if you are still not sure.
