hi everyone,
going nuts trying to find any information about the preheating system on my type 4 motor.
I've scoured the net but can't any pics or reference to it other than an acknowledgement of the system in the Bently manual, section 3 figure 6-3 under aircleaner.
There must have been a bellows type gasket or something that joined the aircleaner inlet to the metal pipe that attaches to the rear tinware but damned if I know what it looks like or where to source a replacement.
Anyone know the part ??

As grumble said.
You will also need to get the vacuum lines connected correctly and check the operation of the thermostat and diaphragm to check it works correctly.

Thanks everyone for chipping in. Grumble’s right that it should have some sort of rubber ‘bellows’ type seal but I can’t seem to find it referenced. The one Kiwi mentioned is for the airhoses that go through the tinware. Good points about checking the action of the thermostat Andy. Trying to work out how to do that
Parts all seem to move and sucking on the vacuum line opens the flap to the heated air intake. Release the vacuum and the flap closes and air is taken from the normal intake hose. I assume that there is a temp rheostat attached to the linkage that progressively works against the vacuum pressure as the engine heats up to close and allow the air to come from the external intake ?

Yep, that is the seal. My bus is complete and factory, but in storage at the moment, so not easy to get photo's.
Yes, many differences in T2's depending on the market, even little things like windows (we never got opening 1/4" windows), but US never got dash fans!
South Africa also got a lot of unique options.
Yes the Ratwell site is a great resource, I had many great conversations with the author when I was restoring my bus (many moons ago)! Really great guy, great attention to detail always giving his time to the VW community.

A trip to Clark rubber and the 50mm cable grommet with some trimming on the inside, did the job. Picked up a few more grommets while I was there to close up other holes. They had some 1.5mm insertion rubber sheet that also is handy for making gaskets. Handy place
