Basically i bought a C4GP the exclusive model 2.0 Blue HDI last week end with 140k
Drove it off and something strange happened: temp setting on HIGH blowing fresh air sometime warmer??
Park it went out again then within 8min boom: warning light STOP THE CAR... i parked the car next day check level coolant: empty wow it was check correct level when i bought the car..
I added water and bleed from the thermostat housing. plug Diagbox monitor: it seem working ok... I think water left from the cap hopefully:
Car recently by previous owner done timing belt and water pump.
could it be the thermostat? if yes hoe to check it?
could it be the timing belt: I did have a light creamy thing on top of the water expension i drip my finger but not that oily.

hope you can help me
