Okay need some help on the hanger on the 71. No transmission hanger for this year bay so how high does it go?
Don’t say it needs to be level, because the hanger sides don’t touch the frame rails when the body and motor are both level.
I’m showing 2.3degrees on the motor with the body level

I’ve been through it more than once 
Late bus has the trans mount so you’re not hanging everything on just the engine hanger like the early bus
The width is snug on the rails, so that’s not a problem
It’s just how high on the rails it should go

From the 3 examples of us using the Busaru support, it looks like we all ran the bolts through close to the bottom of the frame.

Well it’s in , look ma no hands
The new motor mounts were a pita to get bolted down, but a little convincing with the clamps to help finally solved that

Looks good W1K1!
Mounted and installed a pair of 225/75/16 Load E's on the rear to test out my lower RPMs = lower coolant temps theory. Got out for a few drives over the weekend but outside temps were only in the mid 20's C (80s F) so coolant temps were normal, even at hwy speeds.
With the bigger tires, engine RPMs dropped 500 rpm and I find the shift points better. Now 100kph (60mph) is about 3200 rpms instead of 3750.
I like the look of the bigger tire so I may invest in raised spindles on the front instead of the final drive gearing upgrade for my transaxle as both will run similar costs and I won't need to pull the engine and trans to do the spindles.
Will do another road trip to the interior next weekend and temps are forecast to jump up to the 30s C (90s F) so a good chance to test things.

then something is horribly wrong
if you had to load/tension the mounts....expect really bad vibrations and/or droning noise

i just figured the casting of the rubber twisted a bit after they came out of the mould. i still have the original ones i can swap back in if there is any issue.

also here is another heater option that i thought was pretty interesting
https://infernoheaters.com/product-category/heater-series/
it's universal, not VW specific .. looks nice and has various sizes available
the two bigger ones are 32K and 45K BTU
SPAL fans .. which i would assume are the IP68 (waterproof) versions, but worth checking ..
|
Back to heaters, anyone know how many BTU will heat a bay?
I like the compact or slim inferno heaters posted above 16,000 BTUs and a 260 CFM SPAL blower. or 18,000 BTUs and a 520 CFM SPAL, I want a front heater under the pedal pan for driving and defrosting (Canada eh) and I can run a smaller line to push heat back on the seat divider vent.
The rear I'm still thinking just mount a diesel heater behind the passenger seat, since there's already holes through the floor, and use that for camping and added heat on the road, if it's needed .

Pulled the scoop off the rad and added some 3/8" thick rad foam to make a better seal and opened up the intake part of the scoop and went for a long test drive in 30 - 35C temps. With the lower engine rpms and the mods to the scoop, my coolant temps stayed at 90C.

new question, expansion tanks? what are you running?
I have seen both the vanagon system with the expansion and overflow
or the late model VW single ball tank
is there any difference or alternative that you are using?

I'm just using the original Subaru overflow tank connected as it was in the Subaru.

Yes, that's the advantage of using the Subaru radiator, the expansion tank is part of the radiator.
I ponied up for the Afco radiator and the 13" spal fans, and need to drop it off at the radiator shop for the outlet modifications this week. Vee Dub Nut sent me the info on his radiator setup, so I was following that info.
I just wondered about the expansion tank differences being used in the subaru swaps
Busaru has the inline filler and the dorman expansion tank setup on his swap parts list, but he has a few hose connections on his swap info, which seems like asking for leaks.

Most people I've seen are using a Vanagon expansion tank but I just mounted the Subaru overflow tank on the Driver's side firewall as it doesn't take up much room and ran a 1/4" hose from the filler with rad cap on the Passenger side of the firewall.
If you use a filler cap unit like the one in the picture you posted, you could use any tank with a "straw" or bottom inlet if the rad cap has a normal pressure rating.

Finally trimmed the rear apron to fit around the motor and I figured I had lots of space under there, but the 7” diameter muffler ain’t gonna fit . Looks like an oval shaped muffler is going to be my only choice

looked at the muffler again and I was thinking it needed to be tucked up in the space between the motor and apron, but I think it will work if I drop it down with an offset piece of exhaust tubing.
just puzzling over the mounting height for the radiator yesterday, and working on the brackets to hang it, and be able to close the sides and rear end to keep the air flow pushing through the radiator.
At this height the two spal 13 inch fans have no problem with clearance.
also looking at adding some aluminum sheet pieces to help guide the airflow better than just having it swirl around under the floor

Mark,
I'll get you some actual measurements from the Bus tonight, but I did find this picture in the gallery that shows how mine is sitting relative to the crossmember. If I recall that aluminum angle is 1"x2" or 1.5"x2.5" (need to measure to confirm), but you can see my 1" inlet/outlet tubes are tucked right up against the cross member (they were welded in pretty well on the tank centerline from memory). To shroud the radiator I just made some flat panels that slip in and sit on the inner lip of the frame, and then attach to the side the radiator on the flanges on the core. The fan motors at this elevation are right up against the underfloor/control tubes that runs underneath. Overall hang down to the lowest point is maybe ~3", tops. I'll confirm this afternoon.

perfect, Thanks Adam
I see now where you have some foam on the mounts too, that's the problem with looking up threads on your Phone in the garage and can't see details that are obvious when you get on the computer with a 26" screen 
My 5/8" tubing for the front heater should be here today, so I can get that run through the chassis up out of the way and keep working on my radiator mounts now.
