Patent

CA 2750284

A pair of coolant receiving pipes (23) and (24) for respectively receiving a coolant from left and right engine heads of a V-engine are provided on a first body (21) side, and a collecting passage (27) for collecting the coolant, communication opening (30a) towards a radiator via the above-mentioned collecting passage (27) and communication opening (31a) towards a branch passage provided with a heater core part or the like are provided on a second body (22) side and these are individually resin molded. A coolant passage apparatus (10) is formed by joining the above-mentioned first body (21) and second body (22) for example by welding means.
