[Also in Division F1] A lubricating oil cooler 13 for an internal combustion engine is situated downstream of an axial flow cooling-air fan 3, the cooler comprising tubing formed to circular shape concentric with the fan 3. The cooler 13 may have cooling fins 16 attached thereto, which fins may also form guide blades for the air flow from the fan, which air flows through a cylindrical casing 4 and past the formed cylinders and cylinder heads 1, 2. The fins may be curved as at 17, Fig. 2.
