Using your Perrin Radiator Shroud is a breeze. First, make sure your vehicle is turned off and cooled down. Then, follow the included installation directions to bolt the shroud onto the top of the core support and radiator. It's designed for easy installation, so you don't need to be a pro. When your car is in use, the shroud will work to push more air through the radiator, helping it stay cool. As for maintenance, keep it clean by washing it with a mild soap and water solution every few months. Check the bolts regularly to make sure they're tight. Remember, this shroud is made to work with the OEM radiator. If you have an aftermarket radiator, it might not fit, and we can't accept returns due to this incompatibility. So, always double - check your radiator type before installation.
