Deleting the rear heater core in your van accomplishes two things:  it gives you more storage space under the rear seat and it eliminates an area of potential leaks.

This kit uses inline metal adaptors in place of the rear heater core tees in the heater hoses. After you remove the heater core hoses use the supplied rear heater core hose elimination plastic plug from the inside of the van to plug the holes and the supplied metal inline heater fitting to connect the hoses to one another.
