Here is another problem I just ran into. This AAZ came with A/C but now it will not be used. The serpentine belt now has no A/C pulley to wrap around so the belt is much shorter and will run into the water pump and double cross on to the tensioner pulley. The water pump here has a separate belt and pulley coming off the crank.
I have seen pictures of the water pump using this groove belt but I can't seem to find the p/n or even if it will work in this situation.
I can rig up an idler where the A/C was but I'd rather not.
Any Ideas?
Thanks
Tony

you are looking for an obd1 vr6 water pump pulley, then you can use the serp belt on it instead of the v belt.

Can you get a p/n for this one? I try looking for it but I get different choices. Would this be the right number? 028 121 031E
-
and 93-99.5 vr6 pully should work.. used a obd2 on my set up.. but requires some washers to shim it out a tad... look at ror's serp belt issue thread for belt size/info your seeking.. http://www.vwdiesel.net/forum/index.php?topic=31119.0

Or a 93 non-A/C AAZ pully. My car has the serp for the alternator and water pump, and a v-belt for powersteering.
Part number according to VAGcat is 028121031E
The P/N for the VR one is 028121031K

Super thanks. Do have a picture on this setup on your car? That would be very helpful.

If you get a vr6 pulley it works just fine. I have a serp setup like this and I run the water pump off the serp and the power steering it you have it, is the only thing running off the v-belt. You will just need a shorter v-belt than what came with the car.
-
The water pump pulley is just flat steel and so it seems like the back of the belt should run on it. That's not the case, tho. The ribs need to run on the flat steel because the water pump has to run clockwise.
-
Super! Thanks for all the info fellas. I'll be ordering this today from ECS tunning.

why do you have a 16v power steering pulley on your water pump?
you need a VR6 water pump pulley spaced out +5mm
or a VR6 power steering pulley, not spaced at all..

It looks to me like he has an AAZ water pump pulley from the AAZ A/C serpentine setup on his water pump.

That's correct. The engine came with A/C and this truck is not setup for it. I was contemplating on installing A/C but it's too much work.
This truck came with no power steering as well. That's another pulley I don't have to worry about.
It's good to know I only have one belt to worry about. Simple is good when you're out in the middle of nowhere in central Oregon.

I got a hold of the pulley and new Idler. This belt is a 1045mm. It look like it's a little bit long. I am thinking a 1035mm or so would be better.
Since this is the first time I've seen this setup. Is this correct as far as the belt wrap?
Thanks for the help in finding the parts.

correct belt wrap, but you need a 1034mm belt..
6pk-1033 is the dayco part number, i believe..
but im running the 1034mm belt on my GTI, and it works fine.
had a 1054mm belt on there at first, and it was WAY TOO LONG.

This seems to fit just perfectly, and looks exactly like mine on my m-tdi.
-
Tony, shoot us a pic of the actual tensioner spring assembly.. that will tell us if the belt is too loose or not..
-
Went and got the 1035mm and if fits like OJ Simpsons glove. Much better and not too much tension.
Thanks again.

that looks MUCH BETTER... thats just the belt that the dr. ordered!

I've made a couple dipstick tubes for vanagons from steel brake line that bent over the serp bracket and allowed reading the oil lever from the license plate door. Not as much an issue on a Doka but still a nice touch.
-
Hey Libbey you just reminded me about my dip stick. The AAZ dipstick in still on the block. Now that the motor is leaning 50deg, will the dipstick have to be changed to suit the different oil pan? I put 4 qts in it to prime the engine and it was pulling oil but the stick did not measure any.
It looks like I may have an issue with the length.
Thanks

prolly just needs a longer dip stick..

I've never used the stock dipstick because in a vanagon, pulling all the stuff out of the rear hatch to check the oil level is extremely inconvenient and so I can't say what all you need to make it work. I've made several dipstick tubes from steel brake line. The most recent dipstick I made was from a low-B string (130) from my 5-string bass. The dipstick should come very close to the bottom of the pan to get a good reading and so you may be able to just lengthen yours.
-
I see. With a DoKa the engine is more accessible so the stock dip stick position is not an issue. I will try to find a way to make the stick longer. Maybe cutting the tube that presses into the block can work. :)
-
Libby,
I got a hold of a dip stick that is 1/4" longer than the bottom of the oil pan. How far from the lowest point should the dip stick drop?
Should I measure the maximum amount of oil in the engine and use that level as the top/full mark?
I believe it takes 4.75qts.
Thanks
Tony

The amount of oil required for the AAZ installed in a vanagon is up for debate. The spec for the AAZ engine does not really apply because you are not using the AAZ oil pan. The 1.6 in a rabbit vs. the 1.6 in a vanagon had different oil quantity specs because of the change in the pan. All that said, I've found that 4.5 quarts is about minimum w/ the 1.9 in a vanagon. I have noticed that if the oil level is at all low then when I am cruising and then punch it, oil pressure will drop while boost rises. Whenever I notice that happening, I add a little oil and the effect goes away. The only mark I use on my custom dipstick is the low mark where that starts happening. As always YMMV.
