A couple weeks ago I posted this que' on a couple auto type NG's & didn't get a response (Very slow NG's).
2002 F150, have never changed antifreeze. I don't need antifreeze to protect against temp's (warm climate). But, I have heard it is important to change antifreeze because the it wears out.
What wears out, the temp protection or is there a lubricant that wears out?
How much to drain out, and how? One guy told me to drain a gallon and put in a new gallon? That doesn't sound right to me.
Is it important to get all the old coolant out?
Thanks for any advice.
