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.
