The problem: Heater blowing cold air, radiator cold. A few weeks back there was oil in the header tank; the oil cooler was leaking (pin hole, but what a leak !) so I changed that; I had the system flushed and new coolant put in. But now, the heater is just blowing cold air ( thought it was air locked at first but no) . I took car to the garage, says radiator is full of oil, tried to flush it best he could but still blowing cold. Also, over the past year I've replaced the HCV three times ( Two were genuine ford) So that's not the cause.

Getting really frustrated now, so any one with info who's had a similar problem and found the cause, and cure would be a legend in my life time.

The Car: Fiesta Freestyle, 2002, engine 1.8 Endura diesel DI .

Thanks.

All the best.
