If you do replace the intercooler pump yourself, make sure you change the right one, there are two electric pumps, one for the heater, one for the intercooler.

And....

Recently I was made aware that you must use a vacuum bleeder when opening up the cooling system in these cars (especially the intercooler). My XKR took on nearly 2 litres more coolant after being vacuum bled!

Unbelievable, but I saw it with my own eyes.

I think Cambo had in mind not watter pump but separate chargers cooling pump. this makes air very hot reduces power, but i think you still shoudl hear charger whine.
you can do experiment-
1)remoove windsheild pastics
2)add original stock exausts(if you have any aftermarket)
3)drive car to full rpm

you shoudl hear supercharger swisting easily. if its not there and belt is driving it then something really stange has happened to your SC..

I will check everything and do some more research before replacing parts, But I might use that way to test it out. Thanks
