Using the PERRIN Radiator Shroud is straightforward. First, make sure your vehicle is turned off and cooled down. Then, follow the provided installation directions to attach the shroud to the top of your radiator. It's a simple bolt - on process. When it comes to maintenance, regularly check the shroud for any signs of damage, like dents or scratches. You can clean it with a mild soap and water solution to keep it looking good. Remember, this shroud is designed to work with the OEM radiator. If you have a non - OEM radiator, it might not fit, and we can't accept returns because of that. So, before installing, double - check your radiator type.
