Hi
This is a post I made on another forum.
Steve
Wasserboxer in a Beetle.
The Wasserboxer has received some bad press for headstud problems; coolant leaks and assorted other woes. These problems seem to occur when proper VW
servicing techniques are not used, VW coolant and distilled water.
The Wasserboxer motor in my VW Beetle has been looked after as far correct coolant is concerned; I also use distilled water mixed with genuine VW
coolant. I fitted an Oettinger 85° thermostat instead of the standard 87°. These don't seem to be available anymore so I have modified a Mercedes
one to fit. The top part of the thermostat is the same as the VW one, but the lower bypass part has a larger diameter flange. This can easily be made
the correct diameter by first marking out the correct diameter circle with a pair of dividers and the grind the flange down to the marked circle, it
doesn't need to a perfect circle. I also got rid of water-cooled oil-cooler as I have heard that they can fail. I'm running an air cooled oil cooler
with a Setrab thermo block at the front of the radiator.
As far as the rest of the motor goes it is extremely reliable, I give my bug heaps. I have bent one Scat pushrod (I'm now running Berg ones) and had
2 water pumps fail in about 100,000 Ks since 1988 and have had a few coolant hoses fail. My bug is also in constant state of improvement, so some
things are always changing.
The Wasserboxers use 2 styles of cooling systems, basically the 1.9 and 2.1 litre style. I prefer the 2.1 style.
Fitting the motor is much the same as fitting a type 4 motor, same style of flywheel. The thermostat housing which sits above # 3 exhaust port needs
to have some body clearancing. The water hose that runs from the water pump to the thermostat housing needs to be modified at the water pump end. It
basically would run straight through the left-hand rear bumper bracket. Any Beetle exhaust can be used, #1 & # 4 exhaust flanges need to be
rotated 90°. In the engine bay I used basically the whole Wasserboxer cooling system and condensed it to fit. You will need a steel coolant ring main
as the plastic one cant be shortened easily.
The coolant runs to and from the front of the car via 1.5-inch stainless steel tubes. These follow the chassis bolts along the bottom of the heater
channels. I have just upgraded my radiator with a modified Ford Transit radiator. After some gentle prompting from a fellow list user MARTINSR,
yesterday I went out and bought an after market thermo fan from Davies Craig http://www.daviescraig.com.au/. It's meant to be used for a 5 litre V8 and pumps 2120 CFM, so far its working really
well, we are having 40 ° + days down here at the moment. I previously used a BMW radiator and Audi 100 thermo fan. Cool air is brought into the
radiator through an A/C louvered front apron. I removed the deformation plate at the front of the chassis to allow more air in. I had to also remove
the spare wheel well and I just left the rounded edge for a bit of extra strength, I supplemented the spare wheel wells strength with angle steel. My
radiator is around 550 mm across and 450 mm deep on the cooling surface, it's actually a little wider where the tanks are on the side. The radiator
sits on a U shaped holder right down on the chassis and comes very close to the under bonnet and leans forward about 5°. I fabricated a sheetmetal
alloy housing to guide the cooling air in and let the heated air exit over the front end. I basically used some angle aluminum for the edges and then
filled this in with very thin aluminum sheet. In case you hadn't already realised my bug is a super. I have seen radiators fitted to standard bugs
but I have no experience with this. My spare wheel sits on top my fuel tank on a bracket attached to the strut brace.
Original heater channels were retained and warm air is directed from a Toyota troop carrier heater core under the rear seat opposite the battery, to
the interior via early Audi 100 brake cooling fan on the right hand side and via the troopy fan on the left hand side. I have used the rear seat
heater cable to operate heater shut off valve.
My Kombi motor was purchased new in 1988 and is 2.1 litre its DJ engine number type 10.5:1 compression, 112 BHP type. I original ran the motor with
dual webbers Berg cam. In preparation for a turbo the motor was been decompressed to 8.0:1 and the cam changed back to standard. 1.4 berg rockers are
used.
I'm using an after market EFI system with the factory manifold, the injectors in the stock manifold sit in a horizontal plane so the side panels in
engine bay that the engine tray seal fits in need to be modified or removed.

Sounds like a good conversion if you were looking to go along the water cooled path,i am impressed with the detail of the conversion. Thanks for the
info it may prove useful in the future as you never know when you may need such information. Regards Les

Holy Crap! Thanks for that Steve, so much info to absorb and ponder, have been slowed down by VAST amounts of water passing through our hangar and
moving Dub parts to higher ground has temporarily halted anything VW. Cheers once again, Adam
