i have a citroen berlingo van 1.9 tdi 2000 reg. losing water not from radiator. head gasket ok. often overflowing from expansion tank.smells hot when heater is on but now when heater is off. not overheating. any suggestions would be most welcome
if you have water flowing from your expansion tank then your system is pressurising,if your head gasket is ok like you say then would suspect cracked head/block,have you had the thermostat tested?
