I'd have to agree with PF.Get it done when you can if its running alright.I never pay attention to the "years" on scheduled maintenance.It's a crock!Go by miles...be it 7 or 14 years 50,000 miles is still 50,000 miles.Unles there's a warranty involved,then the # of years doesn't matter(IMO).I'd also agrree with PF on the waterpump,two items replaced with one labor cost,will save you a separate labor charge for the waterpump at a later date.
