I have a 2014 Ford Fusion hybrid and I was going to do a coolant flush (106k) on it. I have to do the main system and the inverter system. I planned to drain it. Add distilled water, run it and drain it. Then add a concentrate depending on how much water the system holds on to so I get a 50/50 m…

Don’t use any flush additive. That stuff is used on engines with heavily corroded cooling systems. Tester

Thanks and is the thought process right to use concentrate. It seems when you flush it the coolant system etc could hold about a gallon of water even after draining has stopped. Thus putting 50/50 would really be diluted to less than 50/50. At least that’s what one video said. Or I could gauge i…

Why not bring it to a shop and have the coolant changed with a coolant flush machine? [COOLANT FLUSH MACHINE] No muss, no fuss, and it doesn’t break the bank. Tester

You should just drain as much coolant out as you can and refill with a prediluted (50/50) manufacturer approved coolant. This will insure that no contaminants can get into your system. If you had gone 10 years or so without doing any maintenance to your cooling system and were having overheating i…

[image] Hpsportsfanatic_166976: Also, motor craft vs Prestone? Thoughts on which one? Motorcraft is the OEM fluid, nothing wrong with using it again. If you use Prestone, make sure it’s the long life stuff (usually a yellow or orange color), not the green short life stuff

Coolant changes are so infrequent and coolant variety so crazy (even withing Ford products) I’d want to use the exact factory coolant. The Fusion has used 3 different coolants over the years: https://parts.ford.com/content/dam/ford-parts/resources/motorcraftpdf/Coolants_Brochure.pdf

Yeah I just ordered the OEM stuff. I’m going to do the main system today. But still trying to figure out how to do the inverter one. :persevere:

Flush went well. Couldn’t get to the petcock, even with plyers. So you a technique from YouTube to unplug the line that pumps the fluid into the reservoir tank and run the car to drain it. Put 2.5 gallons of distilled thru the system. Then added the coolant. Old coolant looked pretty good compare…

Getting quotes upward to 200 to have them flush the inverter. Their has to be some info somewhere. Can’t believe I can’t find anything on it.

Ok I saw this youtube video called 2015 Ford Fusion coolant flush Its a very short video. here is the link In this video he shows how to flush coolant. It is not very detailed however. I am curious as to what he did with the other hose he detached from the reservoir. Did he cap …
