{"product_id":"pump-water-193700","title":"Pump - Water for Defender (1986 – 2006) Water - Non AC - Non viscous drive - Includes gasket – STC637","description":"\u003cp\u003eThe STC637 is a water pump designed for Land Rover Defender engines without air conditioning or a viscous fan drive, responsible for circulating coolant through the engine to maintain operating temperature. On the 2.5 Diesel NA and 2.5 Petrol engines, a failing water pump typically presents as coolant leaks from the pump body, overheating, or bearing noise from the front of the engine. Replacing with the correct non-AC, non-viscous specification ensures proper pulley alignment and flow rate for these configurations.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSpecified for non-air conditioning, non-viscous fan drive applications - not interchangeable with AC or viscous variants\u003c\/li\u003e\n\u003cli\u003eIncludes gasket, eliminating the need to source a separate sealing component\u003c\/li\u003e\n\u003cli\u003eOEM-specification replacement matching Land Rover part number STC637\u003c\/li\u003e\n\u003cli\u003eWhen replacing the water pump, inspect the thermostat, coolant hoses, and drive belt as a matter of course\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Land Rover Defender (1986–2006) with the 2.5 Diesel NA and 2.5 Petrol engines, on vehicles without air conditioning and without a viscous fan drive.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
