Chances are this is the heater valve no longer functioning. This is located behind the plastic bulkhead panel at the back of the engine bay, under the bonnet. The valve will have 2 hoses (15mm approx) into and out of it Check you have power to and from the valve. If not rectify this fault first. It's a simple matter to replace the valve, drain enough water, remove hoses, unbolt valve, replace.

If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing. As the water pump should be replaced at the same time as the cam belt every 90,000 miles, you should also replace the thermostat and coolant.If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing.
