ABSTRACT:
Disclosed herein is an internal combustion engine including a cooling system having a first coolant jacket portion for cooling the engine in the vicinity of the engine cylinder and a second coolant jacket portion from which the coolant is discharged. Flow of coolant from the first coolant jacket portion to the second coolant jacket portion is selectively controlled by a thermostatic valve which includes a temperature responsive element which is mounted in heat exchanging relationship with an engine block member at least partially defining a cylinder and which is operable to afford coolant flow from the first coolant jacket portion to the second coolant jacket portion when the temperature of the block member is above a predetermined level.
