Im stressing about my VR running too hot and have ordered a new fan switch that kicks in 10 degrees before it should, and a new thermostat from Dean at intervolks.

Can anyone advise me on..

a) Where the thermostat is located and how difficult is it to change/tools required etc

b) Is there any special procedures in changing the theremostat

and

c) How do you know if your water pump is on its way out? how much do they cost? and how difficult is it to change?

Any insight would be great...Thanks guys...
