Hi, My water is starting to run a little low in my Xsara 1.4i. What coolant is best to add - just normal tap water, deinonised water, distilled water, something else or doesnt it matter!
I have access to a distilled water still at work but the pH of the water is somewhat high at around 10 - I'd imagine that that is a bad thing and best not to use?
Cheers squelch41
