Parts Wanted Thermostat and flaps wanted

[R1Col]

Hi all, I’m in need of a thermostat and flaps for my tin ware, for my new engine.
Can anyone help ? Thanks Colin.

 

[Clem]

I’ve got flaps set. No thermostat though.

 

[R1Col]

Great how much Clem ?

I have two thermostat and brackets but no flaps,

Delete flaps and stat. They are only useful in an artic zone. The engine always warms up quickly enough in our moderate zone. I have a 912 Porsche engine in a beetle and a T2 van 1600 and both are flapless and never have a problem. In the fully warmed up condition they are open anyway. When Beetles were daily drivers I could see the logic why VW installed them for cold days and US emissions. I drove a beetle with no flaps on cold days and never had a warm up problem. Save your money and spend it on an air freshener!

VW engineers didn't design & fit the thermostat system for fun. They are to allow the engine to warm up as quickly as possible and then to control the engine and oil temperatures. Don't forget, most engine wear takes place when the engine is cold. Would you take out and discard the thermostat in your daily water cooled run about?.

Even without a thermostat and the flaps in an .open. position, they direct the airflow correctly. Worth having I'd say.

Hi, do you have a thermostat left and how much do you want for it, thsnks … if you do.

Definitely. The Mexican ones are ok until they fail. So if anyone reads this that doesn’t know, when they fail, they fail closed! What a bright idea that was

The water cooled system has no comparison to how air cooled system functions. Air cooled is direct cooling by a fan with oil cooling assistance and the flaps do not have a control function. As I described earlier the fan is the only device for cooling with increased engine speed giving increased air flow. Water cooled engines use a liquid which is the primary medium in engines transferred by a pump through an air cooled device called a radiator which ultimately cools with the aid of a thermostat and other additional devices. If you rely on VW engineers to support your thesis remember that these same engineers designed a diesel cheat system and that definitely wasn't fun for VW!

That should not happen as they are designed to fail open.

The original bellows type fail open, but i think you'll find the mexican type fail shut.

The flaps do have a control function even if a thermostat isn't fitted. They funnel and direct air over the heads and barrels.



And in the words of the late great Bob Hoover.
"Install a Thermostat
Do it.
The thing will run without it, the better the climate, the better it will run. And if you’re running a full-flow oil filter the main bearings will last about as long.
But that’s it; that’s the limit of the ‘benefits’ you’ll receive from re-designing the Volkswagen engine, because that’s what you’ve done; you’ve told generations of superbly qualified engineers to stick it in their ear, that you know a better way to do it. Unfortunately, without the thermostat your jugs will wear like a *****, as will your valve guides; you’ll burn more gas, suck a lot of oil and have a hell of a time passing your smog check. Of course, all the experts in the VW-specific rags say no thermostat is a wizard idea, along with blue coils and yellow wires itty-bitty fan pulleys and all the other bitchin’ tricks that made them rich and famous as builders of fine automobiles.

What’s that you say? They haven’t built any cars?

Oh. Well, then make them famous as builders of winning racers. Whats that?

Gee... you mean all they do is talk about it? Ummmmm.....

Put the thermostat back in. To a real mechanic, anyone who builds an engine without a proper cooling system -- and that includes a thermostat and air-vanes -- is like a guy going around with his fly unzipped.

Here’s how to do it.
You need a blower housing with a working set of air-vanes.
The connecting-rod across the front of the blower housing connecting the air-vanes together. Plus the spring that holds the air-vanes open.
The right-side set of air-vanes must have a thermostat link-rod.
Under the engine you need the thermostat bracket and the thermostat.

To install, make sure the thermostat link-rod slides down through the head and projects between the push-rod tubes under the engine. Secure the blower housing and generator (I’ll assume you took the opportunity to replace the modified intake manifold).
Under the engine, reach up and thread the thermostat onto the link-rod. Run it all the way up. Now put the thermostat bracket onto the thermostat. Make sure the base of the thermostat fits the opening in the bracket, which is flat-sided to prevent the thermostat from unscrewing itself as it expands and contracts. Now pull down on the whole assembly and fit the bracket over the stud on the side of the sump. Install a flat washer, a warpy washer and a nut. Pull down on the assembly until the air-vanes are fully closed.

Don’t over-do it. Tighten down the nut securing the bracket.

I’ll assume you tested the thermostat before you did all of this, and that your engine has all its tin-ware. The lower tin provides a plenum that insures the thermostat is bathed in heated air from the cylinders and heads.

The bottom line is that your engine warms up faster, idles better, runs sweeter and lasts longer.

On the other hand, you may wish to leave it off, unzip your fly and make your personal style statement to the VW world.

Not the same engineers though, about 60 years apart !.

Yes got one left, thermostat, powder coated bracket and connecting rod, £45.00 plus postage

Just been put onto a guy called Desi Yates on Facebook? He appears to have a whole heap of flaps and linkages, plus I saw a thermostat bracket and some rods in the photos he posted recently
