An engine includes an engine structure defining a plurality of cylinders. A crankshaft is rotatably mounted to the engine structure and a plurality of pistons are each disposed in a corresponding one of the plurality of cylinders and drivingly connected to the crankshaft. A drive pulley is drivingly connected to the crankshaft. An accessory is mounted to the engine structure and includes a driven pulley connected to the drive pulley by a belt. The belt has a load direction extending through an axis of rotation of the drive pulley and the driven pulley. The accessory includes a housing having two slots extending generally parallel to the load direction of the belt and each receiving a fastener therein. A tensioner bolt is located between the two slots and extends generally parallel to the load direction to apply a tension force on the housing in the load direction.

An engine assembly includes a water pump assembly and an oil cooler mounted to the water pump assembly. The water pump assembly includes a rear housing which at least partially defines at least one water passage to fluidly connect the water pump assembly to the oil cooler. A surface is defined by the rear housing and corresponds to a sealing surface on the engine block such that the oil cooler and the water pump assembly are fluidly sealed to the engine block.
