I just bought a kit and it came with coolant but in shipping the bottle was broken and about 1/3 of it leaked out. My question is this. can i just use water and some water wetter for cars. Will that be good enough? thanks.
Yes you can, make sure it is distilled water though.
And water wetter can do some nasty things to plastic, and can deposit a precipitate in your loop. Some regular antifreeze mixed 90/10 water/antifreeze would work just as well or better.
