Hi, Got a problem with my 1987 T16. I've just driven 500 miles up and down the country over the last couple of days. When I'm in town traffic, the temperature gauge stays dead in the centre and the fan comes in as it should. However, when I get up to speeds around 85-90mph on the motorway, the temperature slowly climbs - it never quite gets to the red, but the car does get hot. If I turn the heater on full heat, the temperature will drop pretty quickly back to normal and stay there, no matter how hard I drive the car. If I turn the heater knob back to "halfway", the temperature will start climbing again. Turn it back up to max again, temp falls to normal. This behaviour only even happens on the motorway at high speed - around town the car is perfect. No steam/smoke, no loss of power. So, could this be a blocked radiator - same symptoms as my Capri 2.8 when the rad was silted up on that. Not sure if the C900 suffers from that problem as much though. Or is it the head gasket? Or did I not bleed it correctly when I flushed the cooling system a month or so back? Car DOES use some coolant - around a litre a month. It doesn't appear to be contaminating the oil, and there's no oil in the coolant. Water pump is a bit squeaky and it sometimes looks as though it might be leaking from beneath. I'll change the pump when I get back from holidays in a month.. Could this be also causing my hot running? Or is that more likely to be a blocked rad? Help!! Cheers Mike
