Detailed Product Description

The Baldwin B40128 engine oil filter is engineered to meet the filtration requirements of the 2005-06 Jeep Liberty with the 2.8L turbo diesel engine. Its anti-drainback valve prevents oil from draining out of the filter when the engine is off, reducing wear during cold starts. The 30 psid by-pass valve ensures that oil continues to circulate even if the filter media becomes clogged, protecting the engine from oil starvation. Additionally, the front end check valve maintains consistent oil pressure for optimal engine performance. The filter’s integral gasket provides a reliable seal to prevent leaks, and its 4-mar thread ensures compatibility with the specified Jeep Liberty engine. With a height of 4 27/32 inches (123 mm) and an outside diameter of 2 29/32 inches (73.8 mm), this filter fits precisely in the designated housing.
