Using the PERRIN Pulley Cover is straightforward. First, make sure your vehicle is turned off and cooled down. Then, install the included brackets, tools, and hardware as per the instructions provided. If you have the Perrin AOS PSP - ENG - 611 installed, this cover will fit nicely. During installation, take your time to ensure a precise fit. When it comes to maintenance, keep the cover clean by using a mild soap and water solution. Avoid using abrasive cleaners as they may damage the powder - coated finish. Be aware that operating your vehicle exposes you to chemicals like engine exhaust. Minimize your exposure by not idling the engine unless necessary, servicing your vehicle in a well - ventilated area, and washing your hands frequently.
