Decided to make a new thread asking about this. I need to have the coolant changed in my car, and was wondering if I need to do a flush or drain/fill?
I asked Maple Mazda (since I was going there for an oil change) and they want $110 for the flush, and they don't do drain/fills. Should I just go with the flush? or buy the fluid there and do a drain/fill somewhere else?
Why I am asking is because I saw posts from theMAN saying that the flush machine would likely introduce contaminants from the tap water, and a full flush is not needed anyways (although I am a late from doing it at 96K).
Any comments are appreciated, thanks
Also need to have the transmission fluid done, I saw that the last owner had a flush done at 60K so I'm almost at the time to have it done again. So same question as above - should I do a full flush? or just a drain and fill?
