run it with a t like the factory did to the overflow bottle |

So this means there will be 2 lines feeding the top of the overflow bottle? _________________ 1981 Westfalia with a 2001 Cabrio ABA

Yep, Helps to bleed air out of the system. Just T them together. |

I made some progress today on the coolant hoses. Everything is roughed in, expect the heater core lines. I am capping the heater core line coming of the back of the head and not installing a junction of the water pump for the other heater line...heat will come next year. I will just run the line from the waterpump to the bottom of the overflow bottle.

Here is my solution for the Shieldsflex connection to the water pump. I repurposed the lower rad hose to get up and over the big Diesel engine bracket.

Hi guys- I run VW ADY setup. Old picture now all is sorterd out.
And Im woundering about this line i have made- WITH BLUE CIRCLE.
Should I make all flow go through heater core?

Hi Pechaaa. You engine is different from the ABA engine they are talking about on the thread. If you still have the engine in the picture you just follow the diesel van cooling system in the Bentley. John |

coolant will always take the path of least resistance.
so if you don't restrict the route in the blue circle, you will get minimal heat from the heater core. _________________

This post will hopefully help those doing the increasingly popular ABA 2.0 inline swap.
The factory ABA hoses used on later 99+ cabrios used a modular design that lets you use off-the shelf VW hoses to route the coolant exactly as it was designed via VW but using a much better route. The upper/large ABA hose really doesn't work in a Vanagon.
Things/parts you will need:
(3) lower coolant hoses 2002 cabrio PN 037 122 058
(1) upper coolant hose 2002 cabrio PN 1HM 122 101 B
various vw spring clamps
(1) roll of 5/8" ID heater hose
(1) AEB lower thermostat housing for waterpump PN 030 121 121 B
You will reassemble the hoses so they fit better using the Vanagon Diesel brackets. Note int he pics I have a set of my carrier bars and mounts used but this coolant line routing works with the 82-83 Vanagon Diesel bars/brackets as well.
Bolt up the AEB/ATW t-stat housing:
Re-configure the coolant lines off the back coolant flange on the head so it looks like this:
the line on the right of the pic faces forward so you can attach the heaterhose line going forward to the heatercore/s
This will take some time, but reconfigure everything else you have left from the 4 coolant hoses to look like this around the waterpump:

Guys I have a question on the part number 1HM 122 101 B upper coolant hose 2002 cabrio.
How is it set up? I cant quite get it, either im to stupid or I cant get the picture of how does it work out because for sure im not seeing it in any photo show here nor im finding the part in any part store. Plus the initial coment of "The upper/large ABA hose really doesn't work in a Vanagon." gets me all confused. Please help. Thanks! _________________ Roger

Hi Roger.
I searched part number 1HM 122 101 B and as an example, found this:
https://www.amazon.ca/Volkswagen-1HM122101B-Radiator-Coolant-Hose/dp/B007HO36QC
To me it appears that this part provides most, possibly all, of the hose parts you need to do what the original poster in this thread did.
Caveat: I have not used this part.
Neil.
this also looks like the same part. If you zoom in you can see its all put together with spring clamps so can be taken apart

Yes I did manage to find it in images everywhere but not available anywhere
Thanks for the tip ill do my best to plumb the engine according to your sketches and the examples I just had no room to place that damn thing in to the equation
Thanks my friend! _________________ Roger

I don't know if you're looking at my custom hose arrangement but I'm happy to explain that if you want.
That's strange that the Cabrio hose is not available. I use this web site to search various vehicles in various countries:
https://volkswagen.7zap.com/en/mex/
VW's are quite flexible with parts mix/match so I'd guess there's other VW coolant hose options available.
If you can, get the metal coolant manifold from the donor ABA. Part of that manifold provides a junction between coolant expansion bottle, heater return hose, and return path to coolant pump. It's a very useful part to have. I'd suggest prepping and painting it before install.
web page showing what I did to make that "junction"
https://sites.google.com/site/tubaneil2/shortenedcoolantpipe
Neil.
image of "manifold". That part on ABA should look similar or same.
It's possible to make that "junction" from copper plumbing pieces. Image of 50º ABA with custom coolant hoses I designed showing that "junction". If I recall correctly, I had to modify a brass pipe nipple to fit the 3/4" pipe to make the transition to connection at coolant pump:

Yes thats exactly like I have it set up right now I think ill run it the same way
Because I have the 1.8head I will just eliminate the 2 hoses going to the side of head reroute them to the back of the head with another copper made fitting T ill figure a way our if I dont find it here in Mexicos parts stores _________________ Roger

Are you adapting hoses from the 1.8 (Tiico ?) to the 2.0 head?

Not entirely, only the one that goes directly to the rad from the water pump. Now that I have a oil cooler on the oil filter that has to be taken care of. As far as the connection to the head flange I need to find a pipe that will fit I don't now right now because the donor engine is on the back of the van and need to measure that one out.
I'll post some photos here of both the water flanges to see if they match and if so I'll go for that. _________________ Roger

It's funny how one year has passed and I'm still at it with my conversion!
Wanted to revive my question in this thread as I made some mistakes on the purchase of the cabrio hose (as the original poster suggested and VanagonNut confirmed).
Here the image of what I got to find in the Mexican market back then
I did buy the T for this size of hose to rout it to the colant expansion tank but I think It will not work I need to figure it out and understand completely the drawing. Heck even make my own drawing according to the ABA manual so that I can understand it completely. It's a spaghetti kind of ordeal ha!
So as you can see my hose doesn't have the clamps to disassemble it and I will have to cut the melted plastic that attaches the assembly together.
On another note I think that the problem I will encounter with the plumbing is with the degrees that my engine plate adaptor is oriented, mine is not at 50 degrees completely it was designed for a carburated 1.8 head so it must be less than 50 degrees and I think that I will not be able to meet the clearance for the head water outlet I will post more photos when I'm in the installation process of the engine. This is what I have from yesterday
I'll be posting more photos so this topic is dummy-proof. It's spaghetti I'm telling you ha! _________________ Roger
