1.9 Coolant boiled away had to replace with water!
So a few weeks ago I had my waterpump/cambelt done and I guess at such time the coolant needed refilling. Sadly the garage seemed to have forgotten to actually put back on my filler cap! (Joy of joys!)
At the weekend I got caught in an hours worth of traffic and the Alfa got really hot and boiled away all the water where the cap was off.
As an emergency I had to replace the lost coolant with water out the tap (about 3.5 litres)
So I am guessing it's mostly water in there now, which can't be good for the block/head?
Is there a way to drain the water and replace with antifreeze? Or can I just keep topping up with concentrate and the water will be diluted slowly?
