A power plant enclosure for off-highway work vehicles comprises a radiator guard, a ceiling or hood, a pair of sidewalls, and a floor or bottom guard which are bolted to each other and to vehicle frames to define a power plant compartment. The ceiling has a power plant servicing opening and an air intake opening, and each sidewall has another power plant servicing opening. Closing each opening in the enclosure is a lid of dual panel construction consisting of an inner, meshed panel and an outer, solid panel bolted to each other. Thus each opening can be closed either by both the meshed panel and the solid panel, to shut off ambient air as in subfreezing weather, or by only the meshed panel to admit ambient cooling air into the power plant compartment and to prevent the entrance of flammable matter in nonfreezing weather.
