A water passage is provided separately from an intake manifold to interconnect water jackets provided in a front bank and a rear bank of a horizontal V-type engine. An EGR valve is supported on a valve mounting seat which is provided at a front portion of the water passage. A water passageway through which cooling water flows, and a gas passageway through which an EGR gas flows, are defined in the water passage in proximity to each other. The EGR valve is cooled by cooling wind passed through a fan opening in a radiator and by cooling water flowing through the water passageway.

Why it's free to use
- Filed September 11, 1996 and granted August 27, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 11, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 11, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
