A/C & P/S delete & Serpentine Belt Thread

[Peter Jones]

Yep, but I had to use shorter ones because I removed the V belt pulley.

Here's how it all prettied up, just before installation.

Nice.

I'll be doing mine in situ, so fun fun fun!!!

I'f I'm using the MK3 waterpump/pulley (mine's shagged) would i need to make the spacer? logic says no, but reality says yes!

Are you leaving the cam cover off?

[Peter Jones]

Hopefully it will all line up for you. I think the MK 3 1800 waterpump pulley has a different offset to the VR6 one I used. The MK 4 pulleys are different again.

I left the belt cover off, I couldn't be bothered trying to make the MK 3 one fit around the MK1 engine mount.

Just bumping this thread back up again, I've had a few questions of late about this stuff.

OZGTI I've soft deleted your reply as the picture links were broken. Let me know if you want to upload the pics again.

Time to go belt shopping!

I cut the old belt and marked it at the extremes of the adjuster range to work out the minimum and maximum lengths it could be.



Armed with this I stopped in at Autobarn (It was on my way when running some other errands) and thouroughly confused a 16 year old girl behind the counter. OK perhaps not the best place to ask.

Repco was a few doors down the road and were a lot more switched on.

Here's the missing part of the equation.



Just so there's no doubt.



6PK is the same profile as the original belt. The other part of the code is the length in mm. The original is 6PK1153 and the new one is 6PK1035, 118mm shorter.

Working backwards from this, this belt is to suit the new Mini and the Lexus es300 should anyone need another way to reference the part number.

GAP is showing this part 6K x 1033 http://www.germanautoparts.com/beta/...2/9310/5785607 which should do the trick, and for only US$14.24 rather than the AU$41 repco charged me.
Their verison is 2mm shorter, which will work fine. It's a contitech part too, which is the same as OEM Golf.

And here it is all fitted up.





Hope this helps.

Hey Pete,

I was thinking about the belt routing. Is the belt supposed to run on the ribs when it's on the water pump pulley? i thought smooth pulleys run the smooth side? I changed it on mine and I now get MORE heat through the heater core! So do i leave it your way with the ribs on the smooth pulley or run it the other way, smooth smooth?

Just a thought.

[Peter Jones]

Yep, ribs are in contact with the pulley. VW themselves did it this way on the non A/C models.

I've done at least a dozen race sessions with this configuration and it's worked perfectly. Still using the same belt too

If you run it on the smooth side your water pump will be turning backwards.

[ozgti]

Crap. Better put it back the other way then!

[Peter Jones]

Five years on from the first post, just thought I'd say that the setup has run fine in all conditions on that belt.

It's done 1000's of km on the race track in all sorts of weather and been completely maintenance free.

Just read this and it's a cool little conversion. What's involved in grafting a Mk3 motor like this one into a Mk1? Is there a thread with an install documented in it that comes to mind?
