>Hi fellow list members,
> I have seen a few posts lately about coolant hoses for our beloved
>vanagons. I have a partial list of hoses that I have used, in some cases
>I'm sure there are better solutions, so feel free to comment, add, and
>modify my list. I have used the hose chart "coolant hoses -wasserboxer
>86-91 2wd" from Jim Thomsons site at Old Volks Home.
> We have a napa flaps here so these hoses are their part numbers where
>possible. Some of the solutions I use won't be expectable to some of you
so
>I will list the hoses that require just a trim to the correct length first
>then I will discuss my solution to other more complex hoses.
> Again using the letters and part numbers from Jims Chart, I will state
>the size and shape of the hose in inches and describe them as best I can
>remember. I have an 86 westy, 2wd, 4 speed, and A/C.

>H: vw 252-121-130b napa 7990 right head front to valve. 1" id 6" long
>has 2 60 degree bends.
>
>J: vw 025-121-058e napa 10050 thermostat housing to oil cooler pipe
>.472" id one end, other end .635" , 3" long.
>
>R: vw 025-121-058h napa 9807 expansion tank to pipe tee. ,620" id both
>ends. 90 degree bend each leg 4.5" long.
>
>? napa 777 thermostat housing
>to water pump pipe. 1.5" both ends 90 degree bend 1 leg 6" other 4"
> this hose doesn't seem to be listed on the chart and I couldn't read
>the number on the hose either.Good picture of it in bentley on 19.11. It
is
>the big on there with the 90 degree turn.
>
>O. vw N901287.03 napa 1" hose water pump feed to right side of
>crankcase. 1" id 3" long. I got a napa 1" hose in 3 foot length heavy
>duty hose.
>
>D. vw N902873.03 napa 1.5" hose valve to radiator feed. Again this
>was part of 3ft length hose.
>
>F. vw 251-121-058a napa 1" hose Thermostat housing to valve. 1"
id
>about 2 ft long
>
>G. vw 443-121-107A this is a 7mm hose from a vw flaps, napa here
doesn't
>carry 7mm hose.
>
>K. vw 025-121-058D oil cooler to oil cooler pipe from from thermostat
>housing. No direct solution here. However 5/8" heater hose about 2 feet
>long can be ran directly from the oil cooler to the thermostat housing
>eliminating the need for hoses J and K. I like the one hose solution
better
>than the normal path as there is more clearance from the oil cooler hose
and
>the header pipe. My hose K got brittle and blew coolant all over my clean
>engine.
>
>L. vw 025-121-058G Oil cooler to oil cooler pipe from water pump. No napa
>hose replacement and no good way to eleminate this hose that I have found.
>Maybe someone else can find a sub.
>
>M. vw 025-121-058J 3/8" id napa hose A straight hose will function
fine
>here 3/8 id 4" long
>
>P. vw 443-121-107A 7mm vw flaps. right head to pipe
>
>Q. vw 025-121-108D no napa solution. pipe at water pump to expansion tank
>. 1" id on both ends. this hose is designed to take a lot of flexing
between
>the engine and the expansion tank. I need help on this one, somewhere
there
>must be another application that uses a similar hose.
>
>S. vw 025-121-058B No napa solution. thermostat housing to pipe tee. 1/2"
>id one end 7mm other end, about 14 inches long. Need help on this one also.

> Heater hoses are all 5/8 inch hose and no real big problems here. I
>replaced the Tees for the rear heater with 5/8" diameter Tees on all
three
>points because the originals had 2 5/8 and one 1/2 inch point. 30 feet of
>5/8 hose is needed to replace all heater hoses.Straight hoses will even
make
>the turns for the front heater under the dash without too much problem.
>However if your inside front heater hoses are good I would consider keeping
>them as they require a bit of time to replace. I was considering
connecting
>my heaters in series instead of parallel, but backed off because I thought
>it might degrade the heat. Napa has regular grade or premium grade heater
>hose and so do many other flaps.

>For the rest of the hoses I used copper pipe, 90 degree elbows and various
>copper pipe adapters. This requires soldering some pretty heavy pipe but
>could be done with a plain propane torch. I bought napa heavy duty hoses
>that are used mostly on diesel trucks and industrial applications. This was
>a mistake I would go with regular grade hoses if I did this again. The
>heavy duty hoses has double layers of nylon reinforcement and outside
>wrapped with nylon. It is a real pain to work with and after a couple of
>days working with them I discovered why most Illinois diesel mechanics
>appear to be fresh off the Minnesota and Wisconsin farms.
>I used 6 feet of 1.5 in id hose
> 3 feet of 1.25 in id hose
> 3 feet of 1 in id hose. most 1 in stuff was used on hose above
at
>item F, and O.
>
>A. vw 251-121-082 napa 1.5 and 1.125 inch hose. upper Rad feed hose.
>radiator connection is 1.33" and long hoses are 1.5 inch, straight 28"
long.
>I used some 1.25 in hose at the radiator end and made an adapter using
1.25
>copper pipe, adapter to 1.5 in copper some 1.5 in copper pipe then 1.5 in
>hose to the long feeder hose.
>
>
>B. vw 251-121-083H napa 1.5 and 1.125 hoses. lower radiator return hose.
>same id on hose as A above however a 90 degree elbow is required on this
>one. Use a short as possible 3" or less 1.125 hose, a very short 1.125"
>pipe, 90 degree elbow, 1.125" pipe , adapter to 1.5", some 1.5" pipe then
>1.5" hose. use mostly 1.5" hose here as you need to get up and around the
>spare tire in a hurry. Keep your copper lengths short.
>
>E. vw 025-121-062E napa 1.5" hose and some 1.5" copper pipe. return to
>thermostat housing. 1.5" both ends however this one goes up and over the
>transaxil. use a short 1.5" id hose about a 2.5 inches of copper 90 degree
>up, about 10 inches (check this measurement) 1.5 "id copper pipe up
> line these up so your copper pipe rests nicely in the hose holder above
the
>transaxil) , now 90 degree copper elbow and you are heading over the
>transaxil, install enough 1.5" copper pipe so you line up with the
>thermostat housing. (hint it is best to be a little too long with the pipe
>going over the transaxil or your hose might cause shifting problems). Now
>turn 90 degrees with copper elbow toward the thermostat housing install a
>short 1.5 in id pipe in the elbow. use a 1.5"id hose to connect to the
>thermostat housing. That sounds pretty involved, try this for
>directions from the long return hose go back a few inches up about 10
inches
>over the transaxil about 20 inches and turn back toward the thermostat.
>What you end up with is a copper pipe with 3 90 degree elbows attached.

>
>N. vw 025-121-058M napa 1" hose, home made adapter and some 7mm hose.
>Right head to pipe. one end is 1" other is 7mm. start with a short 1"
>hose, use a very short 1" id copper pipe, 90 degree copper elbow, I then
>used an adapter from my local hardware store from 1" down to 1/4" id
>copper pipe that I used and then just stuffed the 7mm hose over that. The
>origional hose on my 86 had sprung a leak and for a while I thought I had a
>head leak.
