Part # LR018275

hard to visualize with intake manifold in place. After I refilled my coolant form water pump replacement mine took a while to equalize and get all air out. It helped by filling from vent plug but still needed to add coolant for a few days until stabilized running front and rear heaters etc.

Yep, just had the water pump and crossover tubes (plus belt) replaced on mine (2010 with 154,000) yesterday. I could smell the coolant, observe some residue under the water pump, would add some coolant each week and could hear the squeal of the belt occasionally when accelerating. There were no drops under the vehicle so it was only while vehicle was pressurized that the leak occurred. Unfortunately I didn't have some of the specialized tools needed to replace the water pump so I had to take it to the dealer. Land Rover Cary, NC did a great job on the replacement.

Oh oh the leaking coolant is contagious.

I replaced the pump last month but did not replace the crossover. The LR4 left a 18" puddle of coolant in the garage overnight but now it does not appear to be leaking? Anyhow it is at the shop and have my fingers crossed.
