The Mishimoto Toyota Corolla aluminum fan shroud kit will considerably improve engine cooling functions and the overall performance of your vehicle. All Mishimoto fan shrouds are significantly lighter than standard fan shrouds. In maintaining the life of your engine, it is ideal to keep your engine running cool, especially during those unbearably hot days. A Mishimoto fan shroud will notably improve engine cooling performance by delivering more air to the Corolla aluminum radiator and driving out excess heat. The fan shroud will also secure the fan blades in place, which will prevent damage to other essential components in your engine. All Mishimoto aluminum fan shrouds include an adhesive protective strip. This adhesive-backed foam strip seals any remaining gap between the fan shroud and radiator so that the fans are only moving air that has passed through the radiator core as opposed to pulling in air from the engine bay, resulting in improved cooling efficiency.
