I have a Fiesta Encore 1.3 on a R reg. Ive had it a couple months and its using a lot of water. Had an oil change and the oil was in normal condition and had the head gasket tester kit used and it was all ok! Theres hot air blowing out of the heater so it can be the matrix... Left car sat in same place for a week and no visable leak or water lost at all. Whn i run the car its using water like theres no 2moro!

Any ideas and help would be well appreciated!

Thanks

Graeme
