I am very new to this forum so please excuse me if this has been covered before?
I have a mysterious coolant leak, I have been unable to find it now for about a year!
I will run my car from where I live to work every morning which is about 10 miles, by the time I have got there and let the car cool down it will have lost approximately half a pint of coolant, this will happen every time I use it.

The car is running fine, no mayo on the dipstick or the filler cap.

It pressurises up nicely, there is no white smoke or misfire?
Recently I have noticed a slight glug coming from the dash

Can someone please tell me how to test the heater matrix or have any idea where the coolant is going? It is really driving me nuts.
