Using your Perrin Transmission Oil Cooler Kit is easy. First, find a spot at the front of your Subaru WRX (2022 - 2025 CVT models) to mount the oil cooler. Use the included custom brackets and all the hardware provided to secure it properly. Before starting the installation, make sure to check the instructions for the additional oil required and add it as directed. When you're out on the road, whether you're towing or going off - road, the oil cooler will work hard to keep your transmission oil at a good temperature. This helps your transmission last longer. As for maintenance, keep an eye on the oil cooler core for any signs of damage from road debris. If you notice any issues, it's a good idea to check the brackets and fittings to make sure they're still secure. Also, follow the maintenance schedule in the included instructions to keep your oil cooler and transmission in top shape.
