This Kit Contains: 1 X Aluminum Shroud 2 X 12'' Fan (Includes mounting kits) 1 X Thermostat Relay Kit As shown in the picture above Features: The fan and fan shroud effectively drive the heat over and out the engine compartment rather than thrusting it into the front of the engine. The fan shroud basically houses the fan blades securing it in place and keeping it from damaging the other engine components that may disturb the smooth and even operation of the engine. With excellent operating temperature management, allowable levels of engine temperature are stabilized. .
