Either it flows out and you need to look for a leak under the car. Or it goes into the engine. You need to check the condition of the oil. Do diagnostics. Perhaps the cylinder head gasket is broken, it can go into the exhaust system and evaporate there. Diagnostics should be carried out by an experienced mechanic.

Iām after some advice on an ongoing issue that I canāt seem to get to the bottom of.
I noticed an engine coolant warning light flashing up on the dash back in summer. After topping up the coolant it seemed to resolve the issue for the best part of two weeks and then the level would drop below the minimum again. I was topping up every couple of weeks.
Eventually I took it to a local garage and they couldnāt see an issue with the coolant tank but they advised that my car would need the cam belt and water pump changing due to age and mileage and that should resolve the issue..Ā£600 later and the issue with low coolant remained.
I took the car into Halfords Auto Centre for a diagnostic check and second opinion which also didnāt really pin point the issue. They also advised that the cam belt and water pump may need changing (even though it was done a few months prior).
So I took it back to the garage I went to originally and they ran some more checks. They did some kind of high pressure check through the system and they couldnāt find fault. They concluded that I probably needed a replacement coolant tank as there must be an issue with the tank itself.
Ordered a replacement off Ebay and fitted it myself a few days ago. For 2 days I didnāt seem to have any issue and so I thought it was resolved, however today the warning light is back on and coolant seems to have pretty much drained out. Back to square one.
Any advice would be appreciated. Its driving me insane. I darnt take the car too far with no coolant in the tank.
