In my 1965 Corvair, it is in the Front Hood (Cargo trunk), on the driver side by the windshield.
Regular DOT3 brake fluid
Just regular DOT-3 brake fluid is what you need.
regular DOT-3 fluid.
I'm sure you can make them work.
It requires DOT 3.
The brake fluid reservoir is located under the hood, driver side, just to the right of the hood hinge. Generally a black plastic cap/lid; you'll notice the brake lines coming from the bottom of the unit. Clean the top, Unscrew the lid, fill to the mark, put the cap back on and tighten. If it is really low you may need to bleed the brakes (go to a pro for this). Cheers.
Anything but DOT 5...DOT 3 is what was in it at the factory, DOT 4 is better and Synthetic Brake Fluid is also good. DOT 5 is Silicone Brake Fluid; it was invented for the Army and they're the only ones who should use it.
look on the front door post on the drivers side.
I used to own a 1964 Covair spyder and it used 5 quarts of oil on a oil change. Brewski
You need to contact a Corvair Club for an answer from people who really know, based on experience with this engine. I would probably use 10w30 but you may need to use 10w40. I am not 100% sure on this engine.
Fluid Components International was created in 1964.
The first generation ChevyVan was produced in 1964. The first van made by the company Chevrolet was the Chevrolet Greenbrier based on their Corvair model, known as the CorVan, in 1961.
