I have a 2004 F-150 that still has the original battery in it. It seems to be working fine now but I'm getting ready to move to a much colder climate where the temperature is often below 0 degrees. Just wondered if I should go ahead and replace it now to be on the safe side. This is especially important considering the fact that any friends and family will be over 400 miles away and I really don't like the idea of having to rely on strangers or a tow company to jump start me.
Also, how often are you supposed to have your radiator flushed out. I only have 46,000 but I don't know if time or mileage is what matters.
