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).

We only carry the later 438B because it accepts a superior design hose that runs between it and the passenger side cylinder head, with a longer sweep that flexes less and lasts longer, the 025-121-130B. It is in your best interests to update to this superior hose.

• If your van already has the 025-121-130B 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 a long-sweep hose, part number 121-025-130B

• If your van has an automatic transmission it will have a 438A, you need to buy the 130B hose AND do one of two things:

1) Buy a 5/8” T-fitting because the 438B junction 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 whick is highly recommended, read this article to learn why.

Fits 2WD Vanagons ONLY. NOT FOR 4WD Syncro.
