Engine cooling system for vehicles

In a vehicle having a body of monocoque construction and an engine mounted in said body, a cooling system comprising:

• a means disposed on said body defining a plenum chamber,
• an exhaust means associated with said plenum chamber,
• a radiator disposed between an interior portion of said body including said engine and said plenum chamber and operatively connected to said engine,
• a fan mounted in said plenum chamber between said radiator and said exhaust means and adjacent said radiator,
• a driving means for driving said fan, whereby upon operation of said fan air within the interior portion of said body including said engine is drawn through said radiator and said plenum chamber and expelled through said exhaust means,
• an access means on said body positioned generally over said engine for providing access to said engine from outside said body,
• an air inlet means associated with said access means for providing air from outside said body to said radiator,
• a directing means associated with said access means for directing air provided by said air inlet means to said radiator so that the incoming ambient air does not scrub over said engine,
• said access means including a hood member removably disposed over an opening in a top wall of said body,
• said air inlet means including a spacing means for spacing said hood member a distance from said body whereby air may flow through said opening into said body,
• said directing means including a blocking means associated with said hood member positioned over the portion of said opening directly above said engine for blocking the flow of air through said opening away from said engine, and
• said blocking means comprising a cover member connected to and spacedly depending from said hood member, the space between said cover member and said hood member defining at least a portion of said air inlet means.

• said access means including a hood member removably disposed over an opening in a top wall of said body, and
• said air inlet means including a spacing means for spacing said hood member a distance from said body whereby air may flow through said opening into said body, and
• a grate mounted on a top plate of said hood member whereby air may pass downwardly through said hood member.

• an exhaust blocking means for blocking air exhausted from said exhaust means from directly entering said air inlet means,
• said exhaust means including a diverting means for diverting exhaust gases laterally and outwardly, and
• said exhaust blocking means is attached to said hood member on the side of said hood member adjacent said diverting means.
