Thermostat
« on: June 27, 2008, 10:14:40 pm »
If thermostats are so important to the VW Engine? Why aren't they available? They are on the Samba used... but how can you trust that they work?
I'm going to check tomorrow for the pull rods that you check behind the fan housing tomorrow. VW-Resourses said if you have pull rods you have flaps. Hopefully I just need new tin and the 50 dollar used thermostat.   m-d

  THermostat cant be stretched out, in fact there is a tolerance height to them, dont have the book in front of me,

but if you have a few vw books, that specification will be in one of them...........

I don't get what stretched out thermostats have to do with anything. Or is that what usually happens then they go bad? The last thermo I replaced was on my 65 Ford Falcon and that was a lot easier than this lol.

 Engines get hot

Engine heat expands the accordian-type  thermostat

this expansion pushes up on the rod to the flaps to open them

Bad thermostat, one has expanded slightly or grotesquely
slightly, will not move the rod the distance it should
  hence flaps are not opened to the degree they should be when your engine ishot.........
really expanded ones....well, you could not fit under the car at all.


Last year dissasembled and old engine that had a thermostat which was expanded over a foot ( I remember it was over 2 feet, but dont want to seem too crazy  c23 - so I'll say a foot. ) wish I took a pic of it, it was unbeleivable!

That makes sense. I'm going to have to look in he bently book and see if there are diagrams of how the thermo is set up. I know I need a bracket too. I'll look for those measurements in the Muir book for the thermo expansion.

Sky,

thats about the best explanation I've seen as to how these things work. I'm not so sure his repairing one is a great idea but if all else failed, who knows. Keep in mind your bus has the type 1 motor so the flaps & thermo arrangement is a bit different than those with the flat shroud motors. Anyway its a bit warm to worry about them right now!

I've been reading a lot of the articles on that site (and whereever else I can find what appears to be good info).  When you're completely ignorant there's a lot of stuff you need to learn!

Reading that article, I realized that I don't have the wheel, the wire and possibly even the flaps.  >:(
