Does it mean that the water pump is on the way out or has died?
There is no sign of a leak so far.
I opened the bonnet after experiencing a 115 deg C climb which came back down to 100 deg C when the aircon was switched on - a departure from the regular 95 - 105 deg C range.
Is there a blockage somewhere that is causing this expansion?
I haven't really noticed the expansion of the hose before but only did so when I hadn't switched the aircon on and the car was still hot.
The radiator was changed about 7 years ago, not that it needed changing back then, but the stealer could not find the source of a coolant leak - it wasn't the radiator.
What is the typical cost of an XJ waterpump and thermostat and labour?

To clarify - the hose had expanded between the sleeve protecting it from the pulley and the water pump. The rest of the hose was its regular size. I had another look at it now that the engine temp is cooler and the area of expansion went back to normal size.
At the time I stopped the engine running, I could smell a disc brake type smell coming from the wheel area but it could have been the disc brakes.
