Which Sight Glass should I choose for my GoWesty expansion tank?

You must select the version that matches your specific tank. We offer a sight glass for the earlier bare aluminum tanks and a different one for the current black powder coat tanks. Please use the drop-down menu to pick the correct option.

Will this replacement sight glass fit my watercooled Vanagon?

Yes, this part is designed to fit all watercooled Vanagons that are equipped with a GoWesty Aluminum Coolant Expansion Tank.

Is this part compatible with my Vanagon's model year?

This sight glass works with watercooled Vanagon models from 1983 through 1991, provided you are using the GoWesty aluminum tank.

How do I know if I have the bare aluminum or black powder coat tank?

Check the finish of your GoWesty Aluminum Coolant Expansion Tank; if it is plain silver, it is the bare aluminum version, and if it has a black finish, it is the black powder coat version. Selecting the correct tank style ensures you get the right sight glass.
