Hello brothers and sisters, my car is a Peugeot 307 1.4 HDI 2003 model. While the water level is normal, after getting in the car and driving for a few kilometers, the water level warning light comes on. When I check, I don't see any water in the expansion tank. When I wait for the engine to cool down and want to add water, no matter how long I wait, when I open the expansion tank cap, I hear a hissing sound and the water level rises to its previous level. If I open it while it's hot, I think it's the water expanding, but I wait 5 hours and it cools down, but there's no difference. I can't top up the water because the water is low, the water doesn't mix with the oil, it doesn't flow, there's no drop of water where I park the car. The mechanics in the district where I live aren't very helpful, if I can't solve it myself, I'll go to Bursa.
