Volvo Owners Club Forum - View Single Post - How important is coolant antifreeze/water ratio ?

Due to a recent issue with a leaking coolant hose (very short hose hidden away next to the EGR), I had to top up the coolant fluid a few times; sometimes water (if that's all I had) and sometimes orange antifreeze (when I've stopped at a garage).

And given the lack of history before I got the car, I have no idea what the antifreeze/water ratio is.

Once I've replaced the host, is there any harm in me just topping it up with 100% antifreeze ?

In other words, is there any risk in having, say, 2/3rds antifreeze and 1/3rd water ?
