    Coolant Level Low & Lowered Performance

    Hi Guys, as above the coolant level is an inch below the cold mark at cold. I did have a water pump failure which has now been replaced by Vauxhall. Will this have anything to do with coolant loss? Also can i just top this up with water or is it best to top up with coolant? which coolant is the best?

    When the turbo kicks in it is now very hesitant compared to prior to the failure when it pulled all the way! Im getting a little concerned and could do with some advice.

    p.s. car is a 2.0 turbo astra (2002) 28,000 miles using BP Ultimate fuel.

    Topping up with water won't hurt, just make sure the antifreeze concentration is OK before the winter. keep a look out for any further coolant loss.

    Hesitant power delivery coud be one of many things, duff AFM, boost control solenoids etc etc.
    Bearing in mind you had a coolant loss problem, depending on how hot things got, you may now have a crack in your head or block which will could make the car run bad. This is probably a bit of an alarmist diagnosis and unlikely but I have seen this before.

    Check your oil/water for any signs of the 2 mixing and closely monitor any coolant loss, especially now its getting warmer.

    agree with everyone, just remember that the antifreeze concentration has to be right.... antifreeze has higher boiling point than water, and it is used to cool the turbo.

    if no leak is visble maybe it is leaking inside the engine trhough the head gasket, have it checked by an expert.
