A modular engine enclosure comprised of a hood and baffle is provided to channel cooling air along passages formed between their adjacent surfaces to the radiator of a water cooled engine. The passages provide acoustic air barriers and along with selected enclosure surfaces covered with sound absorbing foam, serve to contain engin e sounds within the enclosure. The passages receive air from a generally upright inle t opening and direct it evenly over the top surface of the horizontally oriented radiator. After being drawn through the radiator, the air is exhausted generally horizontally out the ba ck of the engine compartment. The modular construction of the enclosure allows it to be easil y raised and/or removed so that maintenance and service activities can be performed on the engine and its components.
