US Motor Works Engine Water Pump – Fits Jaguar S-Type, XJ8, XK8, XF, XJR, XKR (OEM AJ88417, AJ88912)

If your Jaguar's been running hot or you're seeing coolant leaks, a new water pump might be in order.

This one's from US Motor Works (part number US4124) and it's a direct replacement for a bunch of Jag models—think S-Type, Super 8, XJ8, XJR, XF, XK8, XKR, and Vanden Plas.

It matches OEM numbers like AJ88417 and AJ88912.

Brand new, never installed, and comes with a 1-year warranty.

It's a critical part of the cooling system, so getting a solid replacement like this keeps that V8 happy.

Oh, and standard California Prop 65 warning applies, but that's pretty much everything these days.
