Hi Folks,
My 1242cc petrol punto has recently developed a problem, the heater only runs hot when the engine is running at a reasonable speed, as soon as the revs drop the heater blows cold and after a while the engine temp light comes on. have changed thermostat and run fresh water through the system to clear any blockages, but still the same problem.
