ERC5655 is the coolant pump body gasket for the Land Rover Defender, sealing the interface between the water pump housing and the engine block to prevent coolant loss from the pump mounting face. On the 2.5-litre engines fitted to this generation of Defender, a deteriorated or incorrectly fitted pump gasket typically presents as a visible coolant weep at the front of the engine or a slow loss of coolant without an obvious internal leak. Correct replacement is essential to maintain system pressure and prevent overheating. Key Features Designed to seal the coolant pump body-to-block mating face on Land Rover 2.5-litre engines Should be fitted dry or with a minimal gasket sealant as appropriate to the mating surfaces - always clean faces thoroughly before installation OEM-referenced part number ERC5655, ensuring correct thickness and port alignment Replace this gasket whenever the water pump is removed; also inspect the pump impeller and thermostat at the same time Vehicle Fitment Fits Land Rover Defender (1986–2006) equipped with the 2.5-litre Naturally Aspirated Diesel, 2.5-litre Petrol, and 2.5-litre Turbo Diesel engines.
