Will this brake proportioning valve fit my 1986 Vanagon Westfalia?

Yes, this proportioning valve is designed for all 1983-1991 2WD water-cooled Vanagons and all Syncro models, including your 1986 Westfalia. It's a direct replacement for the original part.

I have a 1981 Vanagon. Will this valve work for me?

No, this brake proportioning valve will not fit your 1981 air-cooled Vanagon. That earlier model requires a different part, specifically part number 211-612-501A. This valve is only for later water-cooled Vanagons (1983-91 2WD) and all Syncros.

How do I know if my Vanagon is a 'later model water-cooled' that needs this specific proportioning valve?

If your Vanagon was manufactured from 1983 onwards and has a water-cooled engine, this is the correct brake proportioning valve. If you have an older, air-cooled Vanagon (1980-82), you'll need a different part. This valve, part number 251-612-501, is specifically for the 1983-91 2WD models and all Syncros.

Is this a genuine GoWesty part, or aftermarket? Will it affect my brake performance?

This brake proportioning valve is a quality aftermarket part, meaning it's manufactured to meet or exceed OEM specifications. It's designed to function just like the original, ensuring proper brake balance and performance for your specific Vanagon model (1983-91 2WD water-cooled and all Syncro). We trust its quality for your vehicle.
