Attached is photo of warning light that I got this morning almost as soon as I left home. (you can see the temp gauge is not even at half way level yet.

Additional information: 

1.       Red low coolant light goes on – then after 10-15 mins goes off.

2.       Water in Radiator seems ok – I top up a bit every 3-4 days – not a lot.

3.       No water leakage under car.

4.       New Radiator installed a few months ago.

5.       New Container next to radiator also installed.

6.       Temperature gauge always goes from stone cold to mid-way – and stays there.

7.       This week performance is now not good – some misfiring on start-up and also over certain speeds and under 20 MPH.

8.       Check engine performance amber warning lit up once – two days ago.

Any help appreciated as this is getting on my nerves now L
