Twin Fan Wiring Guide - Saxperience

Mochachino · 13th January 2011, 17:15

Ok just done a quick search of 'Twin Fan Guide' and nothing came up just requests. Think there is one somewhere though if I looked more.

Ive just done mine and taken some pics after of the process.

Very easy to do.

Requires, 2 x Fans mk2 VTR or VTS and a VTS housing, fuse, Wire for battery + earth, switch, suitable connections for earth and battery.

Tools: 10mm Socket, Philips screwdriver, Stanley knife or wire cutters.

How to remove the fan from a car (havnt had to do this, this time round so no pics)

Remove the above connections, fuse box will need the yellow tab pushing out then pull out the correct connector, fuse 5 iirc, 2 blue wires on the mk2 setup single red one for mk1 setup, earth bolt is 10mm iirc, radiator sensor just has one of the clips U clips that pull out with some long nose pliers.

Then undo the 2 bolts at the top of the surround again 10mm iirc and lift the fan out of it's lower mounts and feed the cables out from between the rad and slam panel.

Heres the guide for assembling the fan.

Get yourself a VTS fan or Mk2 VTR fan as these fit too. I only got a pic of after, so heres how to undo the fan off a VTS:

Undo the 3 10mm nuts holding the fan in place:

undo the clip:

undo the philips screw on the housing, for both sides:

unclip the relay by twisting and pushing:

chop the yellow wire to the fan from the relay:

chop the end off the red wire so you can fit ssuitable connection to the +ve battery terminal

If you aint sure if the fan works, get a charged battery, heres a 6v I used obviously have the fan off the ground Its only on the floor here as I was takin the pic:

Now if it works reassemble into the housing with the 3 10mm nuts.

red +ve obviously goes to the + battery terminal, send this to the switch first with a fuse before. On the other side of the switch have a wire earthing it. The other yellow wire from the fan also earths, so somewhere suitable like inner wing.

Il get pics for the other bits ive just mentioned when I do it in a week or so.

Danny....does the standard fan disconnect somewhere from the rest of the loom???? Just wondered as i wanted to remove the whole housing to clean it up.

The VTS fan has the red wire going up into the fuse box by the look of it. The other one is an earth probably to the inner wing. Its been a while since ive taken a VTS fan off.

If it goes into the loom, which it probably does then I guess it will be the same as the 8valve multiplugs like the lambda ones. If not it will have some sort of connection to disconnect it from the engine loom.

Fitting is just the reversal of this

Good guide by the way db!

When I fitted twin fans to Nicoles vtr, I just cut the vts fan wiring off and then connect the normal vtr fan wiring to it. Works fine lot easier than how you've done it lol
good guide tho

May only be some of them, what year is your mk2?

Y reg, now my fan blows away from the car =[

readie · 15th January 2011, 21:24

could i just connect the red and yellow wires to the red and yellow wires i already have on my single fan? just solder the connections? or will it blow the fuse?

thanks

Should be able to and change the fuse or it will keep blowing. Just half the resistance. Wht else does the fuse for the fan share? If anything.

A small amount of Y Reg's still have the MK1 Parts in. Most of them don't as its normally V, W and X reg's in the transition years, but this may be a one off

swap the wires

Tyanu888 · 16th January 2011, 20:37

I believe the twin fan comes with Saxo's that have airconditioning, right?

thats correct which are only in europe.

I was going to put up a guide for swapping out the rad a fan set from a VTR to a VTS/GTI set. I also noticed that the vtr fan was too fat to fit in the dual surround...

I'm actually going to add another fan i just bought to a switch but im thinking about wiring it up another way... What amp fuse did you use for this? Just the same size thats already in the fusebox?

dolby20 · 14th September 2011, 17:34

I did the wire cut and shut....
Cut the connector off the VTR loom, and connected the two wires from the VTS fan loom
Now my top fuse has blown :/
Fuse 3 (top right in engine bay - 30A) has blown, but fuse 5 (one beneath fuse 3 - also. 30A) hasn't blown??
Should I have changed the fuses to make this not happen?
Please help as I drive distances that would normally require the fan a few times! Scared of the overheating catastrophe!
Sorry for an old thread bump! But better than another new thread
