 |
|
If your Westfalia is over 20 years of age, I recommend you have a look at the insulation above the transmission in the "transmission tunnel", for lack of better words.
You may find something like this:
That is a sagging mess of old, cracked backing and disintegrating foam which has lost much of its usefulness. When you pull it out it will look like this:
Next time you do a clutch or a job that requires for the trans or the engine to come out, you may want to consider to replace that mess with something a little more effective. I chose aluminized Refletix 25'' x 16' "bubble" insulation that comes in rolls.
After I pulled out the old insulation in pieces I put the puzzle back together to get a good idea of the size I needed to fit:
I used aluminium tape to seal the folds and to give it a finished look. I also cleaned the transmission tunnel area. It was remarkably clean with only some glue residue and minor dust.
When I finished it looked like this:
I also added a few patches of sound insulating material behind Reflectix. This should do a better job of keeping the heat from the transmission away from the passenger compartment, and do a decent job of suppressing the noise. |

Very nice work! I did something similar, but not quite as thorough as you. I had an additional sheet of Motor Mat Pro from a different project that I used. http://www.secondskinaudio.com/thermal-insulation/motor-mat-pro.php I simply took some measurements, trimmed to fit, and put it over the existing insulation. It tucks nicely under the wires holding the original stuff in place. It does make a bit of difference (not scientifically tested), and keeps things clean. Also, you don't need to remove the transaxle to put it in place.

Thanks!
The material is held up in place with original wires that clip into place - if you look at the "old" pictures you can see them.
I think the Second Skin material has better noise absorbing properties. If It were available to me I would have used it along with Reflectix.
FYI, I folded the Reflectix material in half and taped it for a thicker application. |

| Everyone should get rid of that foam. It holds water and rots metal behind it. |

Hoping someone can provide some direction, or alternatives (especially since the pictures are gone). My engine and tranny are (still) out and I just noticed how bad my insulation looks.
I'd like to know what people have successfully used as options and how it was held in.
Thanks!

I have a set of the original wires that held the insulation in place. They are in great condition no rust. Pm me if you are interested in them |

there is a place that specializes in custom fab of heat and sound insulation panels - forget the name but they mostly do stuff for the Detroit hotrod market
worth a search - somebody could even ask for bulk pricing and do a resale
what does GoWesty do when they refurb a Van? |

What about not putting anything back? Is that nuts?
I'm doing the rattle trap INSIDE the van for noise reduction.

not at all - it's in the back and there will be plenty of wind noise to drown it out 
the foil material above is mainly for heat |

I'm going to call my style "zen": I'd like to delete anything that isn't 100% necessary. I can live with a little extra noise at the benefit of not having anything hold moisture against metal.
Same with the rear heater delete: the idea of coolant running into a relatively hidden spot in the van is nuts to me.
The front heater I guess I gotta have for defrost, but also doesn't seem as bad of a design - and I'll know sooner if it is leaking. The sweet smell of hot coolant.
The AC that a PO had begun to delete, I've finished and now my radiator area looks nice and tidy.
