Drain Plug - Coolant - Cylinder Block is the threaded plug that seals the coolant drain port in the cylinder block, providing a controlled drain point for the engine cooling system during service or repairs.

Draining coolant from the block rather than only from the radiator ensures a complete system flush and prevents stale coolant from remaining in the lower passages. The plug should be inspected for thread condition and sealing integrity whenever the cooling system is drained.

Fits Land Rover 4-cylinder engines up to and including the 300Tdi, including the 2.25L petrol, 2.25L diesel, 2.5L petrol, 2.5L naturally aspirated diesel, 2.5L turbo diesel, 200Tdi, and 300Tdi.

Frequently asked questions

What does the coolant drain plug do?

The coolant drain plug seals the coolant drain port in the cylinder block, giving a controlled drain point for the engine cooling system. Removing it lets you drain coolant from the block itself, not just the radiator, for a complete system flush.

Where is the coolant drain plug located?

The coolant drain plug sits in the cylinder block on Land Rover 4-cylinder engines, low enough to drain coolant from the lower passages. Draining here, rather than only at the radiator, clears stale coolant that would otherwise stay trapped in the block.

Which Land Rovers does this drain plug fit?

It fits the Land Rover Defender, Discovery 1 and Range Rover Classic with the 4-cylinder engines up to and including the 300Tdi. That covers the 2.25L and 2.5L petrol and diesel variants, the 200Tdi and the 300Tdi.
