Coolant Change

Successfully changed the oil and filter and would like to know the best way to flush the coolant system and re fill.

Coolant looks rusty and a bit weak on anti freeze to say the least.

Is there any existing posts someone could point me at please?

    Don't know if the right or wrong way, but when I did mine I flushed the system through with a rad flush cleaner. Then with the rad and thermostat off I flushed it through again using a garden hose, once the water runs clear fill up with the correct anti freeze and bleed the system of air. This can take some time to get it all out as I found out.

    Thanks bigh,:thumbup1: I have ordered some Wynn's radiator flusher, so should be here next week.

    I guess flushing the system should be easy enough, worried about re filling correctly mind with the risk of air locks.:scared: The last thing I want to do is cook the engine!:scared::scared:

    Is there a right way and wrong way to bleed the air out? or is it all down to how you re fill the system?
