The ERR6299 is a rotor filter for the oil cooler circuit on Land Rover Td5 engines, designed to trap contaminants circulating through the engine oil system. Located within the oil cooler assembly, this filter prevents particulate matter from causing wear to internal engine components. A blocked or degraded rotor filter can restrict oil flow, leading to elevated operating temperatures and accelerated wear on bearings and other lubricated surfaces. Key Features Designed specifically for the Td5 engine oil cooler rotor assembly Direct OEM-equivalent replacement - fits without modification to the existing oil cooler housing Meets original Land Rover specification for filtration and dimensional fit Should be inspected and replaced at each major service interval or whenever the oil cooler assembly is removed Vehicle Fitment This part fits the Land Rover Defender (1986–2006) and Discovery 2 (1998–2004), both with Td5 engines, as well as non-Td5 Defender models (1986–2006) where applicable.
