I have, finally, just sorted my cooling system out. What I learned was that normal temp on the gauge is bang in between the 'n' and the 'o' of the word 'normal' on the gauge.
Mine was all over the place depending on ambient temp and load, not good.
I did a Prenrite radiator flush, replaced the coolant with Penrite 500,000k concentrate at 33% dilution, both radiator hoses including new hose clamps, thermostat and expansion tank cap. Replaced both fan relays with new/secondhand non-coroded ones.
Now it gets to running temp in good time and sits there. If it moves ever so slightly to the hotter end, the main thermos kick in and a minute later its bang on again.
So, after years of worry I am now confident in my car's cooling system, a/c on or not.
