Abstract
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.
