There are several styles of Subaru coolant manifold, only one of which is suitable to be used by RMW as a core. The two manifolds below are the most common variants. Note the bottom manifold (usually found on later models) has a longer, square-sided neck and recessed bolt holes that do not reach the top of the manifold. Rocky Mountain Westy cannot use the square-sided manifold as a core.

Please be sure that your coolant manifold is eligible as a core before you pay shipping to return it for a core refund. If you have an incorrect manifold, you can recycle it as aluminum scrap.
