Are your oil cooler o-rings flattening, hard, or corroding? If so, you may need to replace the o-rings and gaskets around your oil cooler. This is one of the most common oil leaks in the 7.3L Powerstroke, so if you are experiencing problems with your oil cooler, changing out your o-rings would be a good starting point for your oil cooler maintenance.
All Diesel Care and Performance products carry a one-year, unlimited mileage warranty. Additional warranty coverage is available for purchase prior to and after sale.
