This was taken off an engine that was reconditioned about 2 years ago and has low hours since. It was taken apart for inspection and resealed and repainted. Is ready to install.

This is the newer style manifold used on the 3GM30F YEU engines that have a serial # starting with E.

Parts numbers 128397-44900 128397-44901

While not guaranteed to fit, the manifold will probably work on older model Yanmar engines as well

The part # stamped on the body is the part # for the housing only, this is the complete cooler including tube bundle, and end caps and radiator cap
