Coolant warning on engine start. 2018 V8 Vantage

[WarmSince74]

Hi All

I couldn't find anything definitive in the archives so thought I'd reach out to the masses for advice.

I received a Coolant Low warning on the car. So I checked the levels and visually everything is where it should be but decided
to add a little more so I wouldn't receive the warning again.

However, over a week has passed and I am still receiving the warning on a daily basis. The running temperature of the car is normal.

Anyone else had a similar experience, and if so, what was the issue, and is there quick fix?

Thanks

I had this on my first Vantage and it was just a coolant reservoir level switch, 10 min job to replace and £40 ...definitely worth trying that first

I had the same low coolant warning on my 2019 Vantage. There are 2 coolant tanks. Be sure both are filled to the top. The second tank is under the engine cover - it just clips in and out.

Had exactly same issue - wasn't aware of the other top up tank - now fixed!
