Thermo fans....help!

[4mo]

Hey All,

I have been lurking for a few weeks and thought it was about time i joined this community....

My Bora after years of not missing a beat is playing up and thought that the experts here might be able to assist/recommend a mechanic.

I need two new thermo fans as mine are shot, also in the need for control arm bushes.

Any help is appreciated.

I am located on the Nth Shore of Syd if that is any help.

Read through this. You may find that your fans are not buggered at all and that just the internal resistor is broken.

The link to the site that I got the info from is here.

I don't know if this will help you. I did this modification about 9 months ago and so far both the original fans are operating perfectly.

This site was accessed from the vortex thread here:

My fans stopped working as the above. Can I just replace both fans? I don't have the knowledge to make aluminium boards, resistors etc unless someone in Melbourne wants to make a few bucks or slab of beer??

You can, But the new one will most likely have the same exact problem. Making up the resistor plate aint exactly hard thought. Just sketch it out onto the plate drill and cut, screw on resistors and join cables

I got mine repairer under the BS used car warranty from the dealer... it was fixed by Barloworld Five Dock for about $1200ish (inc 2xfans + fuses)

I'll PM you with more details..

lol $1,200! Wow...

Back Door Shen, where can I get the parts locally?

Aluminium sheets and nuts and bolts would be from bunnings or metal place i imagine.
Resistors are here
Arcol | Passives | Resistors | High Power | Aluminium Housed, Wirewound - 5 to 600W |HS100 1R J
And cables from what ever your favourite electrics shop is.

Heres a bit more info if you need it

This fan repair modification was developed for a 2002 model V5 Golf, it will probably be OK for other Golf models especially the V6

Hmm well I am comfortable I can do that sort of thing as long as I have all the correct parts. How many amps is the fuse on top of the battery?

Just ordered the resistors, now to get the plate made up. The rest should be fairly easy... I'm kind of excited about doing the fix given how much I hate MkIV Golfs now

Half way through doing this fix. Can someone please clarify the instructions for me?

I am confused about what to do with the wiring and the in-line fuse(s). What I want to know is, according to the diagram it looks like red/white goes to one resistor, then from the other side of the resistor the new wiring goes through an in-line 30A fuse and then gets 'spliced' into the red/black wiring (you don't physically cut this one). Is that right?

Correct.

Exactly as per the diagram you linked.

The red/white wire on the stock fan harness is the low speed circuit supply which runs into the fan motor (which has an internal resistor inside it).

So you are bypassing the low speed supply going through the original internal resistor and adding your own external resistor.
