Description
ERR4686 plastic filler and radiator plug
This plastic filler plug with O-ring is used on several Land Rover applications under part number ERR4686. It is commonly used on 300TDI thermostat housing/cooling positions, selected radiator plug positions and Discovery 2 differential filler plug points.
Replace this plug if the original is damaged, rounded, brittle, leaking or has been disturbed during cooling system or axle servicing. The O-ring seal is important, so the plug should not be refitted if the sealing face or O-ring has deteriorated.
Fitment varies by vehicle and position. The confirmed data covers Defender 300TDI thermostat housing use, Discovery 1 300TDI thermostat housing use, Range Rover Classic 300TDI thermostat housing use, selected Defender radiator hose/radiator plug use from TA976035, selected Range Rover P38 petrol radiator drain plug use, and Discovery 2 differential filler plug use.
For related cooling parts, see Defender 300TDI engine parts, Discovery 1 300TDI engine parts, Range Rover Classic 300TDI engine parts and Land Rover antifreeze and coolant.
If you need the brass Discovery 2 differential filler plug option, see the Discovery 2 differential brass filler plug.
