Hi
I have a 2010 Holden Commodore , and will be driving to the Tongariro National Park in July. Do I need to add anti freeze to the radiator coolant?

Hi there,
Yes you will definitely need to check the concentration and antifreeze ability of what is already in there, and it may need replacing or topping up. Workshops have antifreeze concentration testers, which will inform how covered you are.
