I recognize that the OEM "blue" coolant is rated as "long life" … and that it may last for several years. However, I've noticed that a few owners have performed a drain and fill and/or complete flush of the cooling system after 4-5 years … presumably to keep the coolant fresh and to replenish the additives. I'm just looking for input on how to re-fill the system after draining the old coolant since whether I elect to change the coolant now or 5 years from now, I'll still need to know. Unfortunately, the FSM isn't especially clear on the re-fill procedure since the diagram that's provided only shows the location of the pressurized cap on the reservoir tank, and does not show the location of the non-pressurized cap … so it's not clear where you add the new coolant. Also, the FSM doesn't indicate the need for vacuum filling, but an earlier post that I came across highly recommended it to prevent air locks. So it's a bit confusing. I'm just looking for advice from someone who has successfully done a drain and fill, with a list of the steps involved.
