Hello to all of you that use and have the thermostat and flaps installed.
About how long should the 65~70 degree one last in normal use.
I had one go bad, funny thing I just happen to be looking this cold morning prior to starting it was expanded. Went to the parts box and installed another one. Should mention this is a type 3 stock dual carbed engine. _________________ Volkswagen: We tune what we drive.

Wish i had a clue on houw to repair them and put them in operation. _________________ Volkswagen: We tune what we drive.

I had two fail over the last year.
The one in my 1679 caught me by surprise. That was a good thermostat for the last 5 years.
No wonder my engine never got hot. The flaps were held open by the failed TS.
The second one failed during installation on my 2180. I was screwing it onto the drop rod and the threaded collar just broke loose under the slightest pressure when tightening it.
If you find a good used one. I imagine they will last for the rest of your life. Or fail next week. You just never know. _________________ I have learned over the years.

They're available new and used in the classifieds.
Not cheap but available. How many did I take off and chuck into the junk bin in the 70's & 80's ?? |

Ah yes! That is what all the California based hot rodders told us to do, one of their hot tips. Then they told us to get rid of the warm air intake to the air cleaner, block off the heat riser on the intake manifold and change to a 009 distributor. Our cars became impossible to tune stumbling, lurching pieces of junk. But we had done all the COOL mods.
We were so naïve and gullible! Stupid, stupid, stupid!!!
Yes I have had the odd one fail. The one on my type 4 engine in the Buggy failed last summer so I ordered a new one in the fall from Awesome Powder Coating and put it away where it wouldn't get lost until I fixed the clutch. Now the clutch is fixed and I cannot find the thermostat...
So... I go from the stupidity of youth to the forgetfulness of old age... there is no winning!!! _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit. (The mass media age) |

About twenty years ago I visited a VW only junk yard and one item on my list was a thermostat and fixings. The "experienced" guy behind the counter argued with me that air cooled VW's never had a thermostat He told me I might as well be looking for a left handed smoke bender or a jackalope. _________________ Roads Scholar &

Such is the incredible influence of the hero experts of the day that continues even now 50 years later!
Oh and did I mention that air cooled VWs don't need chokes to start or heating/defrost systems either? Special cars that defy all that has been learned and proven to work since the days of the Model T!
Now if I can just recall where I put that thermostat... _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit. (The mass media age) |

Are you referring to the small ones some sellers offer? It's my understanding they aren't meant to be used for the flaps. Antonio Triejo responded to a post a while back stating that the Mexican production cars always used the bellows type thermostats until they discontinued them altogether.

Antonio, is your rod for a Mexican thermostat, perhaps? Tim |
Tim, There was/is not any "Mexican thermostat" in the mexican Beetle, never. The only thermostat style installed on the mexican VW Sedan was the bellows style, until 1995, when VW of Mexico deleted the thermostat system.
I do not know why eveybody call "mexican type" to that crapy thermostat: that thing is not for sale / made in Mexico, VW never intalled that stuff in the Sedan.
My Sedan 1994 is DP 1600i (EFI), but may be the thermostat rod is not like the german Super Beetle ones from the 70´s. |
If I'm not mistaken the smaller style are repurposed from some other application. _________________ 73 super beetle thread http://www.thesamba.com/vw/forum/viewtopic.php?t=649622 Back on the Road!

At VW events looking at the "Show Cars", I always try and estimate the percentage with flaps, much less a thermostat.

It looked like he use 70% Isopropyl alcohol if I read the label right, I have read you are supposed to use 98-99% isopropyl alcohol. you could use IsoHEET gas drier [in the red bottle] you find in your local parts house, it is 98% and about the easiest to find unless you want to buy a gallon of 99%.

The putting things in a places where it won’t get lost thing has been happening to me since I was young and stupid so I’m not sure if it’s an age thing!
But considering that I have lost things in places where it would be safe, and I have put many many things in those places and have yet to find them, there might be something to an old twilight zone episode I watched where there is a group of beings that live in a parallel universe that are responsible for the movement of all objects in our world and they have a particular habit of forgetting to move things or put things in different locations and then remembering to put them in the correct place after a bit and it was to explain the phenomenon of finding stuff in places you already looked. |

Yes, they operated a door hidden behind the license plate of late models (which continued to be made in Mexico, hence the "Mexican thermostat" nomenclature) to close off decklid louvers when cold.

I do the same with distributors with the same results, I'm surprised when I find a vehicle with a stock distributor in it. _________________ Roads Scholar &

Same with carbs. Very few will take the time to clean up a genuine VW carb, just buy some Chinese junk copy and slap it on. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit.
