Description:Our custom-made AA5052 aluminum fan shrouds are manufactured to fit our radiators. These fan shrouds are fabricated for use with our electric cooling fans but allow for use with most low profile electric fans.The fan and the 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. Investing in proper maintenance though will considerably benefit the ride and driving quality in maintaining the ideal working conditions of the engine.Shuttered design AA5052 fan shroud to guaranteed airflow passes high efficiently.Make your engine bay perfect.S blade fans, Push or Pull Type design,lightweight Plastic Durable Material.100% Brand new and never been used.Professional Installation is Highly RecommendedNo Instruction Included12" Slim Fan:Diameter: 12'' (Blade to Blade)Voltage: DC 12 VoltsWattage: 80 WFan Thickness: 2.5"Number of Blades: 10 S-Type bladesMaximum Fan CFM: 2150 CFMMaximum Fan RPM: 2000±10% RPMDPI: #829S-Type Blade pull push design, to make air flow more efficient and bring more cooling EffectPowerful 80 watt motor will keep your engine cool.Thermostat Kit:Work with any 12 volt system.Universal fit for any automotive vehicle and electric fan.Activates by grounding electric fans at preset temperature.185'F turn-on temperature, 165'F turn-off temperature.3/8" NPT thread-in brass probe included.Probe typically threads into radiator, water outlet or manifold.Thermostat Relay Kit Instructions：RED + connect directly to battery.WHITE wire to ignition switch power source.BLACK goes to thermos switch.BLUE wire goes to the Fans.Package includes:1X Aluminum Shroud2X 12" Slim Fans1X Thermostat Temperature Switch Relay KitJust as pictures showFitment Radiator Applicable model:1982-2002 Chevy S10/S-10 Blazer V8 Conversion1984-1990 Chevrolet CorvetteFOR 84-90 CHEVY CORVETTE 5.7L L83/S10 V8FOR 84-90 Chevrolet Corvette C4 Small Block V8 5.7LFOR 84-90 Corvette/S10 V8 ConversionFIT V8 Conversion Application ONLYFor the year and models, please check the compatibility.
