    Help Replacing Coolant

    Right I'm going to replace the coolant tomorrow but just wanna confirm a few things first as I've not done it before.

    To drain the existing, I think I've found the drain tap ( bottom right of radiator ), now do I just turn this to the left untill the coolant comes out or remove it completley?

    Manual says my car holds 6.2 litres, so is this mixture ok, 2.2 lires of water & 4 litres of coolant / antifreeze ?.

    I have air con so is there anything else I need to be careful of ?.

    Thanks.

    I think that a mixture of 50-50 will be fine, so 3.1 water & 3.1 Antifreeze

    Yep 50:50 sounds about right. Just mix it in a container before you poor it in.

    Don't be surprised it you only get 6 litres in as you won't get all of the old stuff out.

    Oh yeah - make sure your heater controls are set to hot to drain the heater matrix as well.

    re: Help Replacing Coolant

    You havent drained all the coolant if you only removed the radiator plug. This has only removed the water stored in the radiator and the expansion tank.
    In order to fully flush the system, you need to remove the thermostat (located on the front top left of the block), then remove the top pipe from the top right hand side of your radiator, then flush through with a hose pipe.

    and make sure you use red anti freeze, coz if you mix it with the old stuff, it congeals and sets in your engine!
