The pink fluid in my reservoir I'm sure is old coolant. Don't think I've mixed any fluids together as of right now. Didn't get a chance to change my radiator today but I will either Saturday or Monday. Got my hands on a Koyo radiator for 127 at advanced auto. Looks like a great radiator replacement. Got two gallons of zerex pink stuff also. I'm sure this will fix the small leakage problem. Looking to flush out the system too... do you guys know of a quicker way to flush out the system other than distilled water and running the engine? Lmk I'll ask the guys at work (Just Tires), because I know they have some machine that sucks in all he coolant from the top of the radiator. Not sure if there's a quicker more convenient way to flush the system though.Thanks for the help guys... will let you guys know how the runner is doing after the radiator is replaced.
