BRAND NEW, made in the USAij- corvair thermostats. These thermostats are an
improved design over the originals. Several design flaws in the original have been
overcome with this new design. $99 each, $89 each if you buy a set of two.
Stock design has seveal flaws, leading to shorter
thermostat life.
Awesome Powdercoat thermostat has improved
design, smooth 1 piece bellows, internal stop and a
two year warranty. No one can match it.

The summary list of why our bellows are better than anyone else's.
The nitty gritty detail on how a thermostat actually works,,, and why ours is better!

Now the thermostats are the #1 most overlooked, maligned, and misunderstood part on the corvair engine. Everyone thinks they know how
the work, and almost no one actually understands how they work. Many folks completely leave them off, with the mistaken idea that they
want maximum cooling all the time, so no need for thermostats. This is a huge mistake. Yes, your engine will run with no thermostats
installed, but, would you take the thermostat off of your ford? your toyotoa? no of course not. If you are buldling a dune buggy, a race car,
or a swamp buggy, go ahead and leave them off, but if you are building a street car, you really want to run thermostats. Why do cars, any
cars, run thermostats? Well the engineers want to maintain the engine at the ideal temperature, not too hot, and even not too cold. Why is
too cold bad? Too cold means lower mpg and more engine wear. If you are not running thermostats, your engine is too cold most of the
time. I know that seems impossible, but i have real world test data that shows it. People mistakenly think the stat starts out closed, then fully
expands in a few minutes and the damper doors run full open all the time. This is just not true. In the real world, the bellows expands to
75-80% of full stroke, and this makes sense, the engineers want the engine to maintain a constant temperature, that extra 20-25% is for
when you stress the engine in the mountains,  really hot days, etc.

Here is the stock chevy stat, it is OK, but not the best design, it has several flaws. Now you can find used ones, and "those other guys"
offers new ones, but they have the same problems.

My stat design has solved these problems.  What are the problems with the original design?
1 -the original bellows is brass, mine is phosphor bronze, it all comes down to thermal cycles, any metal will eventually split and fail if you
thermal cycle it enough, brass has a relatively low cycle count, while phosphor bronze is the king of thermal cycling, it can handle many
many more cycles before failure
2 - construction method, the original bellows is a stack of concave discs that are crimped together at the OD & ID, every bit it is a potential
leak point, the total length of weld is staggering at 103" inches of weld, yes, that is over 8 feet of welded joints, that could leak at any point
along the crimp,,,, my bellows is 1 piece, it started out as a flat piece of metal, it was pressed into a can shape, then the bellows are added
by hydraulical pressure in a form. 1 part, zero leak points, a much better design
3 - on the original, the top and bottom and the fitting are soldered on, this makes almost 13" of solder joint, my design has a built in top, so
the solder length has been reduced to 7.5", again, less places to have leaks
4 - on the original, when cold, the bellows are allowed to compress with full pressure against each other, when dirt, salt, and grime get
between the folds, this causes rubbing pressure that can lead to failure, by bellows has an internal physical stop, so that the bellows cannot
press down fully, reducing the likelyhood of wear leaks.
5 - on the original, a used unit has no warranty of course, the "other guys" reproduction has a 6 month warranty, my bellows has a 2 year
warranty, yes, my warranty if 4 times longer.

Looking at how the stat is installed in the lower shroud,,,,, you can see the rod has a special fitting on 1 end that goes into the arm on the
damper door, it also has a special lock down catch, the stat itself is not the easiest part to install into the bracket, you have to install the long
end 1st, then twist in the short end. The hole in the bracket is slotted, so that the thermostat can not rotate once installed. note that when
closed, the damper door is still about 1/4" open at the top, you do not want it completely closed off, when you shut the damper, you can pull
the rod back and see how much you need to thread it into the stat. turn the stat to thread it onto the rod, check how closed it is,, once good,
install the nut on the end of the stat, now you are ready to onto the engine.
