08 Expedition Coolant Change
Sorry for the question if this already exists somewhere - I couldn't find it.
The Expedition needs new coolant and this is the first time I've changed on this motor. Is there a specific write-up somewhere you can direct me to?

Are you set on doing it yourself? Disposal of the old fluid is a nightmare, and there is a lot of it. Doing it yourself also requires finding the plug on the block to drain the block too. Having it flushed by a local shop allows them to do a better job flushing more fluid through the system to get out most settling debris than doing a drain-and-refill on your own. That's my 2 cents anyway.

Just did our 2008 yesterday. Stick a small hose on the petcock on bottom right of rad and open it, draining into a suitable container. Rear left of the block, near the block heater (or frost plug) is a pipe plug. Remove it with a hex key. It gets messy here! I did it on a hoist with a drain pan but it still pours out fast!
I replaced the plug and closed the drain valve and refilled and ran with water. Repeat if you wish. (I didn't because the original coolant came out as clean as new after 241,000kms) Then I drained and filled with new coolant. Easy.
Now, the problem: Not all of it drains out the rad and block. I refilled with pre-mixed coolant but now my freezing point is lowered. Tonight I plan to drain a bit and top up with concentrate instead of pre-mix. In Florida you should be fine, but up here I like protection to at least -40 (and I've had it freeze at that).
Hope that helps.?
