Using the Perrin radiator shroud is straightforward. First, make sure you have all the necessary tools for installation. The shroud comes with installation directions, so follow them step by step. When your vehicle is in motion, the shroud will do its job of pushing more air through the radiator, helping keep your engine cool. As for maintenance, a simple wipe - down with a mild cleaner will keep it looking good. Just remember, this part is designed for the OEM radiator. If you have a non - OEM radiator, it might not fit, and we can't accept returns because of that. So double - check your radiator type before installation.
