Hi hope we are well, so I had the red light corn on dashboard saying check coolant and when I did it was quite a lot below the min mark after I had been driving it, I got home left it over night came back to it in the morning and it had gone up to the minimum mark, I took it took garage and he said to me there are no leaks he left car running for three hours and it did not drop, checked water pump and thermostat and did compression test and said all is fine. It’s been topped up just above maximum and I have seen in two weeks it has dropped down again and I have no idea what’s happening cause of what the garage is saying. Surely there must me a leak?
