Frequently asked questions

What is the NTC3858 coolant adaptor used for?
The NTC3858 is a threaded reducer adaptor in the engine oil cooler circuit. It connects the oil cooler pipe to its port at the radiator side tank, stepping between two thread sizes to join the cooler line to the radiator. It's a genuine Land Rover part, sold individually.
Where does this coolant adaptor sit on the engine?
It sits at the radiator side tank, where the engine oil cooler line meets the radiator-mounted cooler. The adaptor forms the threaded junction between the oil cooler pipe and its port, carrying oil cooler flow to and from the radiator. On these models the cooler is integrated into the radiator end tank.
Which Land Rovers does the NTC3858 fit?
It fits early Defender 2.5L 4-cylinder and 3.5L V8 petrol from 1987 to 2006 (not Td5), Discovery 1 diesel up to VIN LA081991, and Range Rover Classic from 1986 to 1994. Check your VIN against the Discovery 1 cutoff to confirm before ordering.
