Glow Plug for the VM 2.5L diesel engine in the Range Rover Classic.

The glow plug is threaded into the pre-combustion chamber of each cylinder and provides an electrical heating element that raises the air temperature in the combustion chamber prior to starting. This is essential for reliable cold-start performance in indirect-injection diesel engines, where the heat of compression alone is insufficient in low ambient temperatures.

Frequently asked questions

What does the glow plug do on the VM diesel?
The glow plug heats the pre-combustion chamber before starting, raising air temperature so the VM indirect-injection diesel fires reliably from cold. It's an electrical heating element threaded into each cylinder. Without working glow plugs, cold starting on the VM 2.4L and 2.5L turbo diesel becomes difficult.
What thread size is this glow plug?
This glow plug has an M12 x 1.25 thread. Match the thread to your cylinder head before fitting, and take care not to cross-thread the alloy head when installing. The M12 x 1.25 size is listed for this VM diesel heater plug.
How many glow plugs are needed?
The VM 2.4L and 2.5L diesel is a four-cylinder engine, so it typically takes four glow plugs, one per cylinder. They're usually replaced as a complete set, since plugs of the same age tend to fail around the same time. Order four for a full job.
What are the signs of a failing glow plug?
A failing glow plug usually shows as hard cold starting, white exhaust smoke on a cold morning, or rough running until the engine warms. On a four-cylinder VM diesel, one dead plug can be enough to make winter starts difficult. Testing each plug confirms which have failed.
