Keeping the Rover V8 cool is one of the best things you can do for its longevity, and this kit bundles the three upgrades that make the biggest difference into one package. Our friend Troy at Addicted Motors put this combination together, and we are proud to offer it as the Addicted Motors Cooling Kit. Troy chose each piece to work together so your Rover runs cooler and steadier, whether you are crawling slowly off road, sitting in summer traffic, or working the engine hard on the highway. The kit includes three parts. First is the FlowKooler 180 degree low temperature thermostat w/ gasket, part number FKETC4765KIT, which opens at 82°C (180°F) instead of the factory 88°C (190°F) so coolant starts moving to the radiator sooner. It replaces the Genuine Land Rover ETC4765 and includes a gasket. Second is the FlowKooler high flow water pump, part number STC4378FLOW, built with a CNC machined billet impeller that moves more coolant and builds more pressure than a standard pump, which is exactly what the aluminum V8 needs at low engine speed. It replaces STC4378 and also includes a gasket. Third is the Hayden severe duty fan clutch, part number ERR4996HAY, a thermal unit that locks up harder as the radiator heats to pull far more air through the core. It replaces the ERR4996 or ERR3443 viscous couplings. Together these three parts attack the V8's tendency to run warm from every angle. The thermostat lowers the target temperature, the pump increases coolant flow, and the fan clutch increases airflow. It is a simple, proven combination and a great way to keep your Rover cool. This kit is built for the serpentine belt Rover V8. It fits the Discovery I, the 1995 serpentine belt Range Rover Classic, and the 1997 Defender 90. Fits: Discovery I (1994 to 1999) Rover V8 Petrol/Gas Range Rover Classic (1995) Rover V8 Petrol/Gas, serpentine belt only Defender 90 (1997) Rover V8 Petrol/Gas, serpentine belt only Part Number: ADDICTEDV8KIT Free shipping to the lower 48!
