Will this coolant hose fit my Vanagon?

This coolant hose is designed specifically for 1986-91 Syncro Vanagon models, whether manual or automatic, and covers all trims including Westfalia, Campmobile, and Multivan. It connects the lower crossover pipe to the distribution tower. If you have a 2WD Vanagon, this hose is not the right fit, but for Syncro owners, it's a direct-fit replacement.

How does this aftermarket coolant hose compare to the original VW or a silicone hose?

This GoWesty hose is made using original-type rubber, just like the long-lasting OEM version, but at a much more affordable price. Silicone may seem tempting, but there’s no proven advantage for this application, and this hose was built to the same durability standards as the original VW part. Since genuine hoses are no longer available, this reputable aftermarket option (part 251-121-103-AM) is the best, most cost-effective solution for your Syncro.

Do I need any special tools or skills to install this hose?

This coolant hose is an easy install for DIYers with basic mechanical skills—just like swapping other cooling hoses. One thing to note: you may need to trim it slightly for a perfect fit, which is common for direct-fit aftermarket hoses. No special tools required, just a sharp blade or hose cutter, and your usual hand tools. Double-check the old hose routing during removal to match placement and ensure a leak-free seal with new clamps during installation for maintenance-free performance.

This aftermarket coolant hose is the lower right hose that fits between lower cross over pipe and the cooling hose main junction aka distribution tower.

Fits: 1986-91 Syncro Vanagon

Install Note: You may have to cut off a bit off the hose for it to fit. The OEM hose is no longer available and this generic hose is a nearly identical fit. It is low cost, and works like a charm!

Why not silicone for this original replacement? GoWesty does not offer a silicone version of this hose because there is no evidence that indicated the more expensive silicone material/manufacturing method is superior in any way. This hose is an exact reproduction of the original VW formed hose, which was known to last many decades and are a fraction is the price as compared to a silicone version of the same thing.
