Hey Pharellposhy! Let me describe the pair of valve covers from a 2005 These valve covers are specifically designed for the 3.7-liter engine in the 2005 Jeep Liberty. They play a vital role in sealing the top of the engine and protecting the valves and other internal components. If you need to replace or maintain the valve covers for your Jeep Liberty, make sure to get the correct part number to ensure a proper fit. Happy Jeeping!
