A superior solution is available! Check out our Heavy-Duty Anodized Aluminum Coolant Hose Junction.

There were three different coolant junctions used on the 2WD Vanagon. The part numbers of the early ones (1986-87) ended in -438 (manual transaxle) and -438A (automatic transaxle) and the later (1988-91) part number ended in -438B (all transaxles).

If you are wanting the original plastic junction, we only carry the later -438B because it accepts a superior hose (251-121-130B) that runs between it and the passenger side cylinder head, with a longer sweep that flexes less and lasts longer. It is in your best interests to update to this hose.

Fits: All 1986-91 2WD Vanagon only. Will not fit 4WD Syncro.

Ordering and fitment notes:

• If your van already has the 251-121-130B hose, all you need to buy is a new -438B coolant junction, and you are all set.

• If your van has a -438 or -438A junction you will also need to buy the 251-025-130B hose.

• If your van has an automatic transmission it will have a -438A, you need to buy the 251-025-130B hose do ONE of the two options below:

1) Buy a 5/8” T-fitting because the -438B junction we offer is missing the nipple that feeds the original automatic transmission cooler.

2) Replace the original coolant-fed ATF cooler with one of our external ATF cooler which is highly recommended, read this article to learn why.

Reference numbers can be OE part numbers, superseded part numbers, and compatible part numbers. We provide this information to help ensure you're getting the right part for your needs.
