Green-top coolant temperature sender replacement
AMR1425 is the green-top coolant temperature sender used on selected Land Rover 300TDI, MPi and V8 models. The live fitment data places this sender next to the thermostat, including Defender 300TDI, Discovery 1 2.0 MPi, Discovery 1 300TDI, Discovery 1 V8, Range Rover Classic 300TDI, Range Rover Classic V8 and Range Rover P38 V8 applications.
A failing temperature sender can cause incorrect, intermittent or missing temperature readings. If the gauge or temperature reading is not behaving normally, this is a sensible part to check where the vehicle uses the AMR1425 green-top sender.
Several temperature senders and sensors are used across these engines, so match the part number, colour and sender position before ordering. If your vehicle uses AMR3321 instead, see the AMR3321 coolant temperature sender. If you are working through a 300TDI cooling fault, the ERR3291G 300TDI thermostat may also be relevant.
