2.0 EB Motor - Tip When Draining / Flushing Cooloing System

[snek]

My 2022 2.0 EcoBoost Maverick required a cooling system flush (and cooling expansion tank replacement due to a crack).
In the process of this, I needed to buy a hand transfer pump (less than $10 at Harbor Freight) to pump the dirty coolant out
of the leaky coolant expansion tank so it could be replaced prior to the cooling system flush and refill.

Here is the Tip: After replacing this tank, I was about to drain the cooling system using the 'petcock' valve on the bottom of the
driver's side of the radiator, when I realized that even draining this old coolant in to a bucket will be a mess and connecting
a hose to the petcock and putting the other end into a container would be far easier and cleaner. I looked around in my garage
for a small piece of hose that would fit the outlet on the petcock and at least 2' long to hang down into a drain container (truck was
up on ramps). The red hose that comes with this inexpensive transfer pump is the perfect diameter and plenty long enough. This is
worth the $10 alone - plus these pumps are great around the shop for sucking gas out of lawn mower gas tanks so you can tip over
for blade shapening....etc.

If you take on a cooling system flush and/or change yourself - one more tip: to capture the old coolant and/or flush water (only flush
with Distilled water - never tap or well water), use empty 1 gallon drinking water bottles. I saved 6-8 gallon bottles and caps to use for my
collant and flush water. Buy a brand like "Arrrowhead' that used a heavier, thicker plastic for their bottles that will not distort when engine
temp fluid is drained into it.

Using these 1 gallon bottles are also akin to a 'measuring cup' when doing a flush as you will need to know at the end of the flush how much
'clear'
distilled water remained in the engine, as the 2.0 EB motor / coolant system will only partially drain from the petcock. You typically do one or 2
flush cycles. on the last cycle, you will want to know how much water came out when draining so you can add back in undilluted coolant to have
right ratio of coolant to the Distilled water remaining in the engine. This is the beauty of draining into the 1 gallon bottles.

NOTE: If you are going to take on a cooling flush or refill- please have the proper skills, tools, and knowledge for the job (I have worked on my
own cars for many years and just sharing tips that made this task on the '22 maverick 2.0EB easier and faster). I assume no liability for any damage
or personal harm. Please see a trained mechanic if this is confusing or beyond your slills.

I always just look up the capacity of the system from service manuals and add 1/2 that capacity in undiluted coolant to get the correct ratio. It saves me from having to measure anything.

Most of the time though, I don't do a flush but just a vacuum drain & fill with 50/50. If you drain frequently enough, you don't really need to do flushes, especially with current coolant formulas being as stable as they are. I just did the second drain & fill on a 14 year old car with 150K miles. The drained fluid looked as clean as the new that went in. I always replace Ford expansion tanks when I do this, as they're prone to cracks.

I did a drain and fill on my 2022 Ecoboost last month. bought a few gallons pre-diluted Ford stuff from Rockauto. put a piece of hose on the Petcock and drained. Refilled with a clean bucket and hose using the Maddox Vacuum Coolant tool from harbor freight, I have a cheap small pancake tank compressor. Worked great. I just do it every 60k miles and never worry about a "flush".
