Ford Aerostar 2.3L I-4 overhead cam engine uses a twin spark plug cylinder head design with a distributorless ignition. The crankshaft is supported by five main bearings and the camshaft by four. Main, connecting rod, camshaft and auxiliary shaft bearings are all replaceable. The camshaft is driven by the crankshaft by means of a cogged belt. The cogged belt also operates the auxiliary shaft, and through this shaft the oil pump. Tension on the cam drive belt is maintained by a locked idler pulley bearing on the outside of the belt. The water pump and fan are separately driven from the crankshaft by a six-ribbed belt which also drives the alternator.
