In Auckland region, is it important to have 50/50 anti-freeze/water in the radiator! Got this from internet: Freezing Boiling Pure Water:0 C-100 C 50/50 mix :-37 C - 106 C 70 Antifreeze/30 mix:-55 C- 113 C
Does this mean that it should be OK to top up with water !In Auckland we don't have water freezing in our residential water pipes, so I suppose it shouldn't cause any problems in our cars!

anti freeze helps to prevent corrosion

No,You need antifreeze not just for freezing point, but for the corrosion inhibitors.You should see what happens to a modern engine when an owner keeps topping up the header tank with water.It's not pretty.

Yeah, cars that don't have anti freeze in them don't last very long until the cooling system fails very expensively. Don't be a cheap skate.
Topping up with half a litre of water between services, sure. But if it's losing coolant you have bigger problems to deal with.

Antifreeze also raises the boiling point as well, doesn't have to be cold to need it

No, corrosion inhibitor prevents corrosion - anti-freeze raises the boiling point and lowers the freezing point of teh water in the cooling system. They're not the same thing, but almost all coolants have both. However, you can get just a corrosion inhibitor.

I knew you'd be in to say that. Hair splitting is delicate work eh!

Sure you did. It's work that wouldn't need doing if people were more concise though.

only corrosion inhibitor is just as expensive as propper antyfreeze. you might save 2$ if your in luck as almost no one stocks just corrosion inhibitor. i know i had to specially order some for my central heating unit . plus when you finally saved your 2$ you deside in juli to drive up mount ruapehu to show your kids the snow and 8h later the car wont turn over because the block has frozen the waterpump solid and blowen your frostplugs out. but hey you saved 2$ dont forget .

I would just run a 33% ratio to be honest. I've always only done 1/3rd even in the central north island close to the mountains - no issues with freezing, boiling or corrosion.

Accusing people of being hair splitters appears to be the current rage in here, maybe some people don??

Ammo for anti splitters, or in other words, good old fashioned troll bait lol
