So looking at putting coolant my skyline because it getting hot when using only water (coolant leaked then I replaced it with water, hence the heating issue, as there was no issues before when I was running coolant).
Can someone recommend a coolant they have used or a coolant you would advise NOT to use. I have heard organic coolant is good, you basically buy a small bottle then add it to the water in your radiator, anyone used this? I believe it's similar but a bit different to antifreeze/antiboil. Any ideas suggestion advice etc is appreciated, cheers!
