I was hoping someone could help me with my mk4 1.4 petrol Astra
I got her sericed a few weeks ago including an oil change, timing belt and water pump. Before the service the temp gauge used never move at all, but since the service I noticed that every week or so it was getting higher and then today for the first time since I owned the car it went all the way up to 100. I pulled over and checked the coolant level which was empty and what was inside the bottle was browney coloured. The cap had to be eased off as it was full of steam. I then took it easyy out the road to the nearest garage outside which it was on 100 again so I bought a 1 litre bottle of anti-freeze which the car gobbled up within a mile journey, its now empty again. Would it be that I used the wrong type of oil for the service? I used Mobil 1 engine oil I think it was 10w30 or 10w40. Reall need the car for work etc and hope its not knackered!
