Will this Coolant Hose fit my specific Vanagon model?

Yes! This Coolant Hose (part number 025-121-058G) is made to fit all 1986-91 Vanagon models—whether you have a 2WD or Syncro (4WD), any trim level, and both automatic or manual transmissions. It’s designed specifically for the connection between the oil cooler and the metal pipe running to the water pump. As long as your Vanagon falls within those years, you’re good to go.

The hose end going to the pump pipe is slightly bigger—will it seal properly and not leak?

Absolutely! The slightly oversized end (about 1mm larger) is intentional. Once you slide the hose onto the metal pipe and tighten the clamp, it will seal up nicely. This design has been tested on thousands of late-model Vanagons and delivers years of reliable, leak-free performance. Just make sure you use a quality hose clamp and tighten it securely during installation for best results.

Any tips for installing this coolant hose—do I need any special tools or tricks?

Installation is straightforward, and you don’t need any special tools—just standard hose clamps and some patience! Because the end connecting to the pump pipe is a bit bigger, it might feel a little snug at first. To make things easier, a light coating of coolant on the hose end can help it slide on. Once in place, tighten the clamp firmly. Inspect for leaks after running the engine up to temperature; in our experience, these hoses deliver long-lasting reliability when installed correctly.

Tuyau de liquide de refroidissement pour refroidisseur d'huile jusqu'au tuyau de pompe.

Convient à : 86-91 Vanagone

REMARQUE : Ce tuyau n'est plus disponible dans les dimensions appropriées ; cependant, celui-ci fonctionne parfaitement et scelle toujours bien. L'extrémité du tuyau qui se connecte au tuyau métallique allant à la pompe à eau est légèrement surdimensionnée (1 mm), mais se ferme bien sur l'ardillon et se déforme sous le collier pour faire une bonne étanchéité. Des milliers de ces tuyaux à extrémité légèrement surdimensionnée fonctionnent sans fuite depuis des années, en d'autres termes, ils fonctionnent.
