The inlet and outlet passages communicating with a water-cooled engine oil cooler for a vehicle, such as a motorcycle, are arranged for bypass of a regulated amount of oil from the inlet passage to the outlet passage to enhance the flowability of the cooled oil. Provision is made for a replaceable flow control orifice between the oil inlet and outlet passages to regulate oil viscosity. Also described is an arrangement providing for mounting the cooler to the crankcase or oil pan surface whereby air flowing past the cooler during movement of the vehicle assists the effects of the cooling liquid.

A system for cooling engine oil in a vehicle engine comprising: a cooler operative to transfer heat from said engine oil to a cooling fluid; wall means on said vehicle engine forming an oil collection reservoir having a front wall fixedly connecting said cooler on a forwardly facing surface on the front wall thereof for exposure to air flowing during vehicle movement whereby said cooling fluid comprises said flowing air; means for supplying engine oil to said cooler including inlet and outlet passages extending through said vehicle engine wall means and communicating with said cooler and an upstanding flow conductor positioned interiorly of said engine, an orifice in said flow conductor dividing the interior thereof into an oil inlet portion and an oil outlet portion, and oil flow pipes extending between said wall means and said flow conductor for connecting said oil inlet portion of said conductor to said cooler inlet passage and said oil outlet portion of said conductor to said cooler outlet passage; and said oil flow passages are disposed in mutually divergent relation between said flow conductor and said wall means.
