On this one with 420 000 km, it started boiling coolant, tried to refill and bleed it, no luck, runs for a while and then pushes out most of the antifreeze out through the expansion tank. So the new motor (used from autowreckers with 130 000 km on it) was purchased and istalled by them, run for 3 days and started doing the same thing, overheating and pushing out coolant. The temperature gauge does not indicate overheating though, but the same effect, steam comes from under the hood and shortly after the coolant is pushed out. Both fans are runnning on lo and hi. When this happen the fans are not evern running sometimes. Is this a common fault, head gasket, heads or block? Any info is apreciated.
