Hey what's up I have a RB25 in my s13... that I just got yesterday I had noticed it was starting to peak in temp but not over heat so I went onto some forums and saw that properly cooling this engine is specific. I checked the coolant and it was the muddy look so I drained it out and put some new stuff and I'm actually going to drain it again tonight and flush it out. Do you guys have any additional info that could aid me in getting this to not happen again. Thank you!
