Would a faulty thermostat cause my problem?

it can cause overheating, but the water loss is puzzling

Thats what mine did, are you getting white exhaust fumes, mine ran clear, coolant system overpressurised because of crap coolant and dodgy thermostat and airlock

now that is a good sign, when head went on our original engine, it looked like a steam train :cry: Is the engine oil emulsified?

Then I doubt that head or gasket have gone, check thermostat, radiator and expansion bottle caps, make sure they bleed the system

mine was off the road almost 2 months, but in the end I changed the thermostat, replaced any dodgy hoses and clips, changed rad cap, changed expansion bottle cap, flushed the system, flushed it againand again, then filled with good quality coolant and bled the system, at that time I had not seen manual and just bled it by instinct. It has done several thousand miles now, up some big hills and the temp stays constant. Hope this does not sound bigheaded, it is not meant to :oops:
