2005 4x4 Expedition w/ rear heat.
163kmi on Odometer, engine replaced at about 95k mi w/ a used replacement engine w/ 63k mi on it.
I inherited this truck, so don't have much knowledge on it. I'm handy, but a moron noob when it comes to cars- go easy on me...![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I live in AZ, and it's super hot here (118+ degrees outside). Sitting idle in the drive thru lane for a while, the truck overheated on me. It popped the degas cap, sprayed coolant all over the engine bay. Let it cool, filled it with drinking water and limped it home. Drove it for a few days, no problems whatsoever since. I decide to flush the coolant, since I doubt it's ever been done before. Found the Ford Tech's youtube and followed the steps as follows...
Basically, drained it via the radiator petcock, then added the coolant flush cleaner and garden hose water to the fill line. Ran the truck to temp w/ heat on front/rear, drove it a few miles, and drained again. Then I ran the garden hose to the degas bottle, left it overflowing the bottle and the drain open, running it through the system until it ran clear (took about 45min w/ engine running, revving it to 2500 rpms once in a while, etc). Felt confident it was 'clean' at this point, so closed it all back up and added 50/50 mix of Gold coolant and distilled water...
BUT- it only took about 2.5gal of the 50/50 coolant, and the manual suggests 20.7qt (just a little more than 5gal). So that means there's about 2.5gal of garden hose water still left in there...
QUESTIONS:
1) Should I drain it all again and add new 50/50 mix, and if so, how do I get the remaining 2.5gal of water that's still in the system? Or should I just drain about a gallon out, and had a new gallon of full concentrate back in? The manual suggests a 40% mix in my extreme heat climate.
2) I DID NOT change out the thermostat, but I see how cheap/easy it is to do... I assume I should do this as well?
3) Any other maintenance type items I should do while I'm performing any of these other things?
Thank you all for your insights!
