Undo the knurled nut on the top cooland hose, used to bleed the system, then rev the engine up. If you get a nice big water spout, you can bet your ass the water pump is making pressure. Sticking the stat in a bucket of hot water wont test anthing, as it has an opening pressure as well as a temperature.

After a reasonably long drive today I was almost home and then noticed the throttle cut out a little - temperature warning light on and diagnostics showing around 120*C ! Oh dear. Rev'd the engine a little and the temperature dropped to normal, so made the final 13 miles back in a gear lower than normal and with the heater blowing hot. Interestingly the A/C fan (which does work) did not cut in as I thought it should do in an overheat situation. I will be replacing the water pump, radiator (still has original) and thermostat (even though it's genuine and only 2 years old).

Anyway, what are people considering to be the BEST Td5 water pump? I know Pro Flow are popular, but their association with Britpart puts me off and I think the one that's in it is a Pro Flow and is only 4 years/ 30k miles old.

I remember people used to talk about the Airtex water pumps - does anyone have any experience with these?

Failing that i will just get a QH one, but just wondering if there's anything better. I'd have expected a Pro Flow one to have lasted more than 30k light miles. Thermostat I will stick with genuine, the radiator will probably be NRF unless they're not available then I'll go for a Nissens one.

You don't say if you checked your vehicles viscous fan was fully functioning, so we have to assume you did.
There are only three failures the pump can have, a leaking indicated by a drips from the weep hole, a faulty impeller shaft bearing, an a broken impeller which has be mentioned in forum sometimes.
But you have now replaced the pump.

LR like other vehicle manufacturers use various pump manufacturers to supply the pumps, the same for a lot of other parts that are required, its the only way they can keep up with the parts for the numbers of their vehicles dropping of the assembly line every day.

So as long it listed as original equipment manufacturer OEM it will okay so it will fit exactly not how long it’s function will last, the water pump fitted to my disco lasted only 40,000 mile, so much for quality LR branded parts.

i hear he best water pump is Land Rover branded, even though it costs around 4 times a pro flow one. a friend's proflow pump only lasted a year so i can see the association with s*tpart

Not necessary, my discos water pump bearing failed around 40,000 miles, but an LR branded item means the replacement will fit
