    Afternoon! I hope that everyone is safe and well. I have recently bought an Astra H 1.6 Hatchback from a dealer with a coolant level warning displaying on the radio screen every 5-10 mins when driving. This can be dismissed but is annoying and I want rid of it! I have already replaced the...

  4. Astra G leaking at radiator bleed nipple - can someone help me explain please?

    Astra G
    Hi all, I have had my 2004 1.6 8v for a few months now. I do very few miles in it and normally only small journeys of a couple of miles. One of the first things I did was change the coolant as it looked like it had not been done for a long time. In order to drain the coolant I used the bleed...
  5. Water coolant hose ID please

    Astra H
    Hi, I've got a leaking hose which is leaking coolant everywhere. Definitely coolant as the expansion tank empties after about 10 miles and definitely this pipe cos I can see it spurting out of it. What I want to know is the part number of the pipe if I have to buy it from dealer (or where else)...

  8. Coolant warning light

    Astra G
    Hi, The coolant warning light comes on and off randomly, it seems, on my astra g. The engine coolant level hasn't changed and the light comes on with or without the ac on.

    Hi guys, To me this looks like a worn water pipe / perished rubber leak, but just wanted to get your opinions before I contact mechanic.
