Land Rover Defender 90 110 Water Pump 200 Tdi STC639 – Replacement Cooling Part

If you’re keeping a Land Rover Defender alive, you know the 200 Tdi engine inside and out.

This water pump (part number STC639) is a direct replacement for the Defender 90 and 110 models.

It’s all about keeping that engine cool and reliable, especially if you’re off-roading or just daily driving a legend.

This is an aftermarket part, but it’s made to OEM standards—no universal fitment headaches here.

It mounts right up to the engine and does exactly what it should.

Classic car part?

Absolutely.

Performance part?

Nah, just solid function.

If your old pump is leaking or noisy, swap it out and get back on the trail.
