I can't get any heat from my 2000 Fiesta 1.8 Endura DI!! I have changed the header cap, heater valve and thermostat. I have also flushed the system fully and refilled with antifreeze. The engine quickly gets up to temp and runs bang in the middle of the gauge. I believe there is an airlock but I can't seem to clear it. I noticed that in the Ford TES information the bleeding of the DI engine coolant system is unique, but unfortunaetly I don't have the data on how to do this as the disk I have is corrupted. The system also doesn't appear to pressurise, as I can remove the header cap even when the engine is warm and though there is a small amount of pressure release, it is very small.
Any help would be much appreciated as I am getting close to smashing the car to pieces with a hammer. Luckily I am so cold when I get out of the damn thing I just want to get in the house and warm up. I refuse to be beaten on this one !!!
