Thread: 2.7 water pump failure ?

Hi Ean, I also changed my water pump when timing belts were changed. The water pump I took out was in very good condition so have saved it as a spare. I also changed both belt tensioners also so now ready for another 160k or 7 years of motoring
Cheers

Hi Ean

I had my water pump replaced under warranty at around 35,000km. I could not tell there were issues with it, I'd never seen any coolant under the car but the Land Rover specialists that serviced the car told me there was evidence of the water pump having leaked. I took it back to the main dealer who replaced it without any issue.

Just for the record, my water just pump failed on my 2012 D4 at 239,000km. It started losing coolant at approximately 250ml per 100km, this steadily got worse as the coolant was leaking out at about 500ml per 100km. The low coolant warning did work when this happened. It was a fairly easy job to replace the pump. The bearings were shot on the old one.

Whats a new pump worth?

Is it possible to check this via the level in the coolant overflow bottle? Where does the coolant leak from?

Just change it dude. I did mine, simple as. Best done when you do a fluid change though, but you won’t lose an awful lot

Water pumps have a witness hole where when the seal/bearing goes fluid drips from it.

I ordered the pump from the UK it was about $55 plus postage of $90 from LRparts, I threw in some other bits and pieces to make it worth while. The pump was made by pro flow in UK who are an OEM supplier to LR.

Coolant leaks from the witness hole or shaft seal under the pump. Mine was difficult to diagnose from the top of the engine as the drips were infrequent and evaporated, as it got worse it dripped on the protection plate and mixed with the AC condensation. I could see that my coolant level was dropping and I could smell the coolant, I originally suspected a radiator coolant hose or head gasket.

To confirm I took the small steel plate off from below the radiator and I could see the leak on the bottom of the pump, it was didn't show until the engine warmed up (area corresponds to yellow writing on the new pump).

I didn't drain the fluid I siphoned as much as I could from the reservoir then positioned a bowl under the pump and collected it, to refill I passed it though a coffee filter a few times and reused it. The hardest part was removing the fan, I had to make a wrench to hold it.

For peace of mind replace water pump with timing belt is easiest and most labour effective way with also the plastic coolant connector on top of engine.

Water pump part also available via Ford.

No need to remove timing belt on the 2.7d. Inspect and replace accessory drive belt if necessary is all you need to do.
