The thermostat is a vital part of your Land Rover Defender 2.25 or 2.5 NA petrol/diesel engine’s cooling system. Its job is to regulate coolant flow, opening at 74°C to maintain the correct operating temperature. A faulty thermostat can cause overheating, poor fuel efficiency, or slow warm-up, leading to engine wear and costly repairs. This EAC thermostat includes a jiggle pin to allow trapped air to escape, ensuring smooth operation and reliable temperature control. Replacing a worn thermostat restores proper cooling, protects your engine, and keeps your Defender running efficiently.
