old pipes are out...in pieces. Yep, it's a dirty job indeed. I was only able to lower the rear of the fuel tank about an inch. Any idea what may be catching? I've undone the 2 bolts at the front of the tank. I still have everything fuel related connected with the exception of the fuel filler neck which I've unscrewed from the body.
Tomorrow should be a hoot! lol

fuel filler neck needs to be removed to drop the tank not just unscrewed from the fenderwell.
it passes thru a hole in the frame. |

Hi Shorepig,
Juggling and positioning the tank is a lot easier with a wood ramp setup as referenced in my post here:
https://www.thesamba.com/vw/forum/viewtopic.php?p=8764410&highlight=#8764410
Also that plastic crossover pipe is a bugger because it is inflexible and short. I replaced it with a new piece of rubber fuel hose. Made it longer. Easier to hook it up once the tank is back in.
Have fun.
P.S.
I just read that you are based in Squamish, home of the infamous “Squampton” Doughnut. Hilarious.

Thanks for the tips guys!
Questions:
1- Does anyone recall in what order they installed the 4 new SS pipe sections? I'm thinking fronts first (up and over fuel tank), then rears, then attach 2 fronts to 2 rears, then make connections to engine, then connections to radiator. then lots of twisting to get alignment correct. Is it ok to use dish soap to Lube up my connection points?
2- There was a metal strap that I cut through that held the 2 coolant pipes and 2 heater hoses up against the frame. I had to cut this to get the coolant pipes out. What was your solution to reattach, or re-hang these pipes a this location?

Shoot! I just realized I could have unscrewed that metal bracket that was holding the coolant pipes to the frame. The screws to take it off were hiding under the heater hoses. Ugh.

Easy enough to make another, just get one of the lighter weight Simpson straps from the lumber section at Lowes or Home Depot and in a few minutes of bending, cutting, and drilling you will have another one.

Thanks for everyone's help. Mission accomplished. Pipes are in, and I didn't have to drop the tank right down. Just lowered the back end about 4", and avoided removing any fuel lines. Tomorrow I'll bleed the system and fire it up!

Raise the rear reservoir 20 inches higher than the radiator bleed port when you fill it ---- then just walk to the front, remove the bleed screw and let the air out.
This could be called the Libby Bongless.
I've always wondered if you could put in all the coolant you can, then drive it (a very short distance ! ) to the nearest steep little slope ( for rear 20" higher!).
The radiator is 10 inhes higher than the reservoir, so the Libby bong at 20 inches provides 10 inches of extra oomph. And parking on a slope with the rear wheels as high as the front center does the same oomph. But you may only need a little more than 10, not all 20.
This is about 8° or 9°, use the angle function on your phone.
This 'slope' would have to be pretty nearby like like 3 blocks or ???.
I have no idea how far you can drive an un-bled Vanagon.
But you don't want it hot such that you can't remove the reservoir cap or the bleeder.

Hi guys I'm having problems with the coolant filling procedure. I'm following the Bentley manual. The only thing I did differently is I filled the coolant container on flat ground first because I needed to drive my van for 1 minute in order to get the front up in the air to bleed it. I figured I should get some coolant in there before running it...now I realize it was a mistake.
So with the nose way in the air, engine at 2000 rpm, rear bleeder and rad bleeder open, I'm not getting any coolant coming out of rad bleeder screw. Coolant is filled to top of drivers side coolant tank. The rad is hot, the return hose from the rad to engine is hot too. What should I try next?
Should I try Sodo's method?

I may be completely wrong here but I believe you want the back end higher than the front - which is what Sodo mentioned.

Libby bong works great.
Do a search on it pretty simple and cheap
To make . |

Try looking up the Libby Bong method in FAQ’s. It’s proof against this idiot for filling the cooling system. Thanks ?Waldo?, btw.

I have never found it necessary to raise either end of the van to bleed the system. Crack the bleeders on the radiator and coolant loop and open the heater valve, fill the engine as much as you can, start her up and add additional coolant to keep the expansion (pressure) tank full. Once it will not take any more use a folded match book or something to hold the throttle valve open far enough so that you can see the fluid level draw down in the tank, add more fluid until the level holds steady right at the top, put the cap on the tank, walk around to the front and shut the bleeder followed by topping off the overflow tank if needed, close the bleeders on the coolant loop, done.
If your thermostat doesn't have a bleed hole the whole operation may be harder to do. |

The idea of the libby bong is to raise the level of the coolant above the radiator bleed screw. You can use a spare front radiator hose to do the same like this. Ignore that this is a subie setup. The same can be done with the regular position. Since I always carry spare coolant hoses this is a available to me. It fits snug into the pressure tank top.

Thanks guys! Did what Sodo recommended and worked like a charm. Hard to believe the Bentley manual method didn’t work. I’ve cycled my cooling system, van wirks, gauge works, no leaks, only issue is the vented cap allows me to suck air through it which is a sign of a bad cap so I’ll replace that.
I’m still wondering why the day my coolant system blew up prior to the pipe bursting I had no heat. To recap, I started the can, idled it for 10 mins, temps read normal on gauge but no heat. I blipped the throttle then there was heat. Later that night the pipe blew up.
