ive the bearings collapsed you will feel excessive play on the pulley. Other than that remove it and check the finns

They usually the seal fails or seals and bearings fail but on a lot of recent engines the water pump impeller is made of plastic and seperates
from the shaft hence loss of water circulation recent VW group cars are very prone to this and it is not unknown on the Rover KV6.

The earlier V6 Duratecs were reknown for this as well.

if you turn it in the correct direction and no water is pumped, thjen it is duff.
in olden days, the pump rotor was made from cast iron and would rust over time. antoehr problem disintegrating rotor due to cavitation, whcihc occurs
at very high rpm. in a tuned high revving engine, either a smaller diameter crank pulley is fitter or larger diameter water pump and alternator
pulleys fitted.

If you suspect yours is broke then changing it wont be too expensive. I have a new one in the garage as a spare. Not sure how much they are new but
probs not a lot.

Could you replace a section of silicone hose with a section of clear hose? Maybes from B&Q?
Obviously not as a permanent measure, but while the coolant is cold / warm and at low pressure?

Hmm remember not much will flow until the thermostat opens.
Check the thermostat is opeating correctly.
Take to the kitchen, put in a pan of water, heat. Check temperature with thermometer, and check it opens / closes properly at the right
temperatures.
Simples chk
