SOURCE: how to change cool'nt in a VE commodore holden

to change the coolant in any engine you need to firstly remove the bottom radiator hose when the engine is cold not when the engine is hot and drain the whole system.
You then need to get some coolant from your local supplier and it will tell you on the container the proper ratio of water to cool it. Once you have put to cool it in top up the system with clean water.Regards

SOURCE: what is power trains on a vz commodore

I take it there is a light on, It usually happens when u play around with your exhaust system. The easiest thing to do is turn off all the emission related / o2 sensor codes so it wont bring up the "check powertrain" light again.
Any performance shops who has the software should be able to do this for a small fee. Make sure they dont turn it off completely though, just the emission related codes.
