OE Aftermarket LR005765 Engine Coolant Thermostat with O-Ring for Land Rover V8

The OE Aftermarket LR005765 is an OE-specification replacement engine coolant thermostat designed for Land Rover V8-powered vehicles. This thermostat plays a critical role in regulating engine operating temperature by closing to retain heat during warm-up and opening to route coolant through the radiator once optimal temperature is reached.

A failed thermostat—whether stuck open or stuck closed—can lead to poor fuel economy, reduced heater performance, or engine overheating. Replacing it with this OE-spec unit restores proper thermal management and protects the engine from temperature extremes.

Key Features:

• OE-specification replacement thermostat built to original Land Rover design standards
• Regulates coolant flow to maintain optimal engine operating temperature
• Includes thermostat O-ring/gasket seal (part number 4362513) for a complete repair
• Compatible with 4.2L supercharged and 4.4L naturally aspirated V8 petrol engines
• Direct replacement for OEM part numbers LR005765 and PCP500050
