How To Perform A Coolant Flush On Your Ford Vehicle

[@riverratranger1427]

God bless the man who TELLS YOU WHAT SIZE WRENCH to use! Thank you.

[@garyh9039]

We have some pretty hard water in my area, so I didn't use tap water. On my '03, I merely drained the radiator and refilled with distilled water, drove around for 10 minutes with the heater on to insure the heater core got flushed too. Repeated that procedure 6 times, I think it was, until finally it looked like clear water draining into the bucket. Then I added 2 gallons of Ford Gold coolant to top it off. Checked with a specific gravity meter, it shows 59%. At only 88,470 miles, the original coolant still looked clean but it was 17 years old at the time. I didn't use any kind of coolant flush chemical. That was 3 years ago almost to the day. I don't drive it that much. Maybe 1500 miles between annual oil changes. Been subscribed to your channel a couple years now.

Have question similiar to one asked before but was not answered. Followed video procedure to change coolant today on 2006 F150 5.4 liter with coolant capacity 20.9 quarts. Removed cap on coolant bottle on cold engine and drained coolant thru hose attached to drain plug to get it all. Removed draincock at end. Only got about 6 quarts measured in 2 gallon milk bottles then stopped draining. Added radiator flush to coolant bottle then added water and as expected it only took the same amount of about 6 qts to fill it. Ran engine and drove with heater on high for about 20 minutes to clean coolant system. Allowed to cool some then drained again and again only got about 6-7 qts. Flushed with hose and drained with stopcock out at idle, as directed for several minutes till water coming out was clear. Refilled with water and drove again with heater on high for about 10 minutes. Allowed to cool some and drained again with draincock out. Only got 6-7 qts out again. Flushed at idle for a few minutes with hose, draincock out and engine running to get foam out of bottle til water coming out of stopcock was very clear. Filled with distilled water. Drove a bit then drained 1 more time with cover off of coolant bottle and only got 6-7 qts out. Added new full strength antifreeze and it only took 6-7 qts. All the time I was driving had lots of heat with heater on high and temp guage reading normal regular temp right in the middle. So if I had plain water in the system then and only could add 6-7 qts of full strength antifreeze, how do I achieve a 50/50 mix when there is 6-7 qts of antifreeze and about 14 qts of water in the coolant system?

If you can access the coolant drain plugs in your block it's a good idea to open those up when you are flushing the system with your garden hose.

[@Shanonmcnab576]

Yeah but for the DIYer you don't need to. You'll just be introducing more air into the system. You have to be careful too because sometimes it's damn near impossible to get air out deep down in the block without having to take into the garage. Just saying. I myself don't recommend the Do it yourselfer to do that but not my vehicle just remember there is that chance of it happening. If it happens your looking at a new flush but garages hook up a suction tool with shut off valve connected to a air compressor to suck all that air out from the block and will use another line that is connected with a different shut off valve for the feeding system to put new coolant in. Most DIY people don't have that.

[@rodolfojuarez6113]

Just THANK YOU. That says it all. If you ever come to Oaxaca México let me know, it will be my pleasure to share a meal. The best videos, by far.

[@chriss1227]

Just did this on a 2011 expedition. I used Motorcraft VC-3B coolant. It took me about 3 hours. The hose I attached to the radiator was a 3/8" and was about 6 feet in length. The petcock is on the passenger side by the bottom right hand corner of the radiator fan. You can get to it without removing anything else, but it's a tight squeeze for bigger dudes. I used a flathead screwdriver to loosen it as the petcock on my vehicle was round and grooved so a wrench wouldn't work. If you use a stubby flathead you can unscrew it like a normal screw as there is a large groove cut out in the center.

[@joelung9070]

I just have to say thank you very much... Your videos are very helpful. I have been subscribed to your channel ever since I purchased my '05 4.6 l V8 rear wheel drive F-150. You're the first place I go to find information on what I need to do for my vehicle and I cannot thank you enough. I filed your procedure exactly! The only thing I did different was after I ran the vehicle flushing it with water to get the cleaning solution out and let the system drain once clear of the cleaning solution. With the cap off the reservoir tank and the drain plug from the radiator completely removed. I started the vehicle and ran it 10 to 15 seconds then shut it off. Then another half gallon to 3/4 gallon of clear water drained out. Then I filled it with cooling solution. Hopefully I didn't mess anything up. I've used your channel to do a complete rotor, caliper, brakes and brake system flush. Complete coolant system flush. New front Monroe coil spring and strut assemblies replacement.

One question. The water at the end of this, still inside the engine block ,is NOT distilled water. Distilled water is recommended when adding antifreeze when it isn't 50% already diluted. Wouldn't it be better to add distilled water in the reservoir to flush out remaining undistilled water before adding the last step antifreeze? Or is it such a small amount it doesn't matter? **** Looks like this was covered in another post.

What was the response? I can't find it. Also, how do we know how much is in the block? Should I add premix or full strength coolant?

When I fill after the flush I add straight concentrated coolant of the amount that will be 60% of the listed coolant volume in the owners manual and fill the rest with distilled water. When a flush is done you never get all of the flush water out and if you add 50/50 or 60/40 to the water retained in the block and heater core it will dilute it and you won’t have enough freeze and additive protection.

Brian, thank you for all you do. I wish every mechanic had your professionalism! I had the dealer replace the coolant on my 18 Exp Sport at 37k miles from orange to yellow. However, the coolant was still orange, so I decided to do a flush. I followed this video but did not use distilled water for the final flush. I topped off with a 50/50 mix (distilled) and have since drained and replaced a few quarts with concentrate to bring the levels up. I estimate the system had 4-5 quarts of tap water in it of 13 required. Do I need to worry about the tap water, or should I flush the system again using distilled water? I'll likely change the coolant in another 30k miles. I also noticed the inlet tube collapses when the system cools. I've read this is normal; can you confirm?

Shouldn't you use distilled water instead of plain water from the garden hose to flush the system? I noticed that you have been spilling a lot of water with coolant. Are you collecting all this liquid or is it going down the storm drain?

[@FordTechMakuloco]

If you have a source for pressurized distilled water yes but I don't know anyone who does. What is best is after the garden hose flush is to fill with distilled water and coolant mix. Even better if you are that worried after the flush you can fill the system with distilled water run until hot to get flow and then drain it out once again this way most if not all of the remaining water left in the block is distilled. If your area has really hard water I would not use a garden hose no but here in Chicago tap water is ok. The coolant is collected in a pan and when flushing the remaining coolant water mix goes down the drain in a separator tank at the dealership.

How much does the cooling system hold? Is it's all water in there after the flush what is the best way to figure the 50/50 mix? Do you just take the colorant capacity and divide it in half and assume that's what's left in there for water? Do you recommend using the premixed coolant or the straight and dilute it?

@@nathonsmithson3024 What he's saying is that it doesn't matter how much water is already in the system. If you put the correct amount of concentrate in and then fill it to the line you'll have a 50/50 mix. For example, my owner's manual says 21.2 quarts for engine coolant capacity. That means that I need 10.6 quarts of undiluted coolant and 10.6 quarts of water for a 50/50 mix. If there are still 3 quarts trapped in the system, I can add my 10.6 quarts of coolant and then fill to the line with water without measuring - since the capacity is 21.2 quarts and there's already 13.6 quarts of fluid in there, it'll only let me add 7.6 quarts more water before I hit the fill line. If there are still 5 quarts trapped in the system, I add my 10.6 quarts of coolant and then fill up to the line with water and it will only take 5.6 more quarts of water before I hit the fill line.

[@nathonsmithson3024]

@@thighcurlcontest ok. while correct in most cases certain variables apply to this theory. some vehicals develope large air pockets. even a flush doesn't remove all coolant all the time. aftermarket setups like rads and oil cooler deletes and engine swaps debunk this theory including finding the factory capacity to the coolant system. best advice is get a 7 dollar tester. premix to your desired temperature range and adjust accordingly. to liitle antifreeze is verry seldom a problem. most of the time i see engines that heat up too slowly in winter and have poor heating/defrost due to to much coolant. you may have to a half gallon and add coolant or water to that half gallon and retop off once or twice. if your way off you may drain a gallon and add a gallon of coolant or water to offset. dont guess. just test and do it correct. could be the difference in a cracked block or more than likely defrost that clears your windshield in 5 minutes as apposed to 20 minutes. think about it. spend an extra 30 minutes testing and adjusting when filling or an extra 15 minutes waiting on your vehical to warm up every day through the winter. keep in mind your engine is healthier and more fuel efficient at operating temperature . the sooner you get it there the better. on a diesel in the winter this is crucial.

***** In the diesel the coolant would get so hot from the engine. Usually what happens is there is problems with the exhaust cooler.Its part of the egr system. When you have failed it heats the coolant up past its boiling point ans starts to separate the particles. It happens mainly to 6.0 and 6.4 powerstrokes. The common sign is a white residue on the top of the degas bottle.

[@SVTPerformance]

nickelwork87 The problem with Motorcraft Gold in the 6.0s and 6.4s (but particularly the 6.0) was the solid precipitates falling out of the solution and clogging the oil cooler. This in turn would starve the EGR cooler of coolant, allow it so get too how, it would then crack internally, and finally lead to any number of costly failures. All because of a coolant that contains silicates.

[@SVTPerformance]

FordTechMakuloco I've seen clogged oil coolers on gas engines from the Gold coolant as well, along with a general cruding up of the cooling system in general. That's something we pay particular attention to in racing and towing applications. The Rotella coolants (and any number of other quality ELCs) do not contain the silicates which cause the failures. The Rotella Ultra ELC was actually designed with modern (emissions equipment laden) diesels in mind. It has a corrosion inhibitor package that works great aluminum intensive engines. The best parts about those coolants is that they keep the cooling system extremely clean and don't need to be changed for 600,000 miles.

[@FordTechMakuloco]

***** They found the gold just wasn't cutting it and causing front cover cavitation on the 6.4L hence they went to OAT coolant for the new 6.7L. Diesels are allot harder on the coolant.

Thanks broksi, I don’t work on cars but I definitely changed my water pump the other day. It was first time I physically performed maintenance on my car. I have to flush my cooling system cause it keeps overheating and I think the sludge is playing a big role in my car performance lagging

Nice vid.... My ford owners manual says to use distilled water .. maybe cause of the mineral contents in tap water???

[@awesomearizona-dino]

Hi Haily...Distilled water is a waste of time and money, clean potable water is fine. If you put distilled water into a cooling system, it will tend to leach out metals/minerals from metal components. In dealerships we used to see a lot of pitted aluminum when coolant turns acidic, THAT is your biggest worry. On modern cars cooling system maintanance is critical, And getting trickier with every generation of engine design.

[@DrPhilSays]

@@awesomearizona-dino good to know, thanks. My owners book said demineralized water and also on different pages also said distilled. i guess ford wanted it to go bad in the future and get the repair job..... however, maybe if the water is virgin to start with we can control the final solution composition with the factory coolant additive package in the antifreeze jug?? Sorta like motor oils have their own additives and so do gasoline companies... Maybe there are some minerals in the antifreeze jug?? Thanks again

It depends on how clean your tap water is. I'd undoubtedly go with distilled water. A 4l jug at Walmart is less than $2. Just make sure your coolant hasn't already been diluted.

Great video, My transmission pan has a sticker on it that says external transmission filter installed in cooler line filter line must not be installed when flushing the cooling system. Do I have to worry about this when I use your procedure?

[@mikedavis5784]

Wow! I must be old school. First, I always measure the drained coolant that comes out, so I know how much concentrate to add back in later. Second, I flush with distilled water only, not with tap water that will remain in the system after you drain. Finally, after doing the rest of the procedure similar to what you have shown, and the drained fluid looks clear, I refill with the same measured amount of new concentrate that was initially removed to provide a 50/50 system mixture and then top off with 50/50 distilled/coolant. This way I don't introduce all the minerals and chemicals that are in tap water. Only distilled and coolant for my truck!!

[@chicanopowers4938]

Mike Davis , in Arizona we got super hard water, so using anything but distilled water is asking for cooling system failure in the summer time.

[@mcrider333]

so if you know the cooling system holds 5.4 gallons and there is left over water in the block after flushing why do you need to approximate the percentage of antifreeze to water when you refill? why not just fill with 2.7 gallons of anti freeze and then top off until full with water. then you would have the perfect 2:1 mix. am I missing something? thanks. doing mine this weekend so I hope I do it correctly.

[@JD_Spencer]

I have a 2003 ford escape that keeps loosing coolant somewhere I've looked everywhere for leaks and can't find where it's going. Im putting about a cup worth about every week to week and a half. What else could it be besides a leak? The engine runs great but it's just bothersome because I'm constantly having to check the coolant level. That's not normal is it? My heater is working great too...the level just goes low in my bottle. I'm stumped but I know it's not supposed to be using coolant that fast...I've looked everywhere for a leak.

[@FordTechMakuloco]

+jdspencer8 The coolant pump is the most common spot for a leak on these. Have you check this area underneath for white traces of coolant that burned off?

[@JD_Spencer]

+FordTechMakuloco Thanks for the reply! ..... I haven't yet checked under the coolant pump as I'm still in the process of trying to identify where everything is located. i recently purchased the vehicle and it's my first Ford. I've simply been checking visible hoses and vicinity of those for visible leaks and fluids. Also none on the ground or frame. When you say coolant pump do you mean water pump? I will check this and look for signs of white residue. I'm also trying to figure out the best way to drain and refill the transmission fluid on the 03 cd4e. I've watched your other video about changing the fluid but it seems to be a newer model escape than my 2003 as my drain plugs don't match your video. I'm just trying to learn and locate and get a handle on the maintenance schedule. If you have any tips on how to drain the transmission fluid on an 03 I'm all ears on that as well. I'm hoping to drain and add back from the top somehow.

[@JD_Spencer]

+FordTechMakuloco or is the coolant pump up under the bottle? ....that's an easy check to look for white residue. But I'm confused as to how to drain the transmission fluid on the 2003 escape and combing through the forums is like wading through the quicksand of conflicting information. I could add it in the top if I could figure out how to get it out...or even find the drain plug. There's a transfer case drain plug I can see but still searching for the transmission drain plug.

[@FordTechMakuloco]

The coolant pump is on the backside of Bank 2 cylinder head so the front cylinder head in the back there will be another pully and belt that goes down to the water pump check this area and the hoses going to it for leaks and white crust. As for the transmission yes you have the older CD4E trans that takes Mercon V not LV. It has a 3/8 drive plug in the rear of the bottom rear of the trans you use this one as the drain. Be sure to use Teflon paste on the plug going back in after the drain as I show and link to in the other escape trans video. Then the trans is simply filled through the trans dipstick tube as a normal trans is filled. Start with 4 qts and check and adjust from there at hot idle in park level surface hope this helps!! Here is the fluid yours requires- www.amazon.com/gp/product/B000NU67V8/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B000NU67V8&linkCode=as2&tag=fordt-20&linkId=R2BG6P3THOACQTCT

So mercon V will work in place of regular Mercon as noted on my dipstick? hmmm...that's interesting. So thankful for the help. I'm going to take back the Dex/Mercon I bought because it had on the back that it was for pre-2006 fords that take Mercon. I'll then get the Mercon V.

Yes, it’s fine to use garden hose water for the flush. The distilled water is real inexpensive, just send 4-5 gallons of it through, after the flush. Then just fill it up.

[@sojministries337]

7 years later is this still the same? Now we use distilled water right? So how do we keep the flush going since we can’t use hose?

I would just use hose water as you flush and then when you’re finally ready to put the coolant you wanna keep you distilled water

Great job !!!...but is there a way to test if the solution proportion is adequate (water-coolant) ?

[@timgiles9413]

How I do it; 1st, add a bottle of your favorite coolant cleaner. I use Prestone. Take it for a 15-minute drive, turn the temp knob to Hot. Put the truck on ramps. Allow the engine to cool completely. With the engine COLD, remove the Degas cap, Locate and loosen (do not remove yet) the engine block drain plug on the driver's left side just below the rear freeze plug (there are 2 but the starter blocks the r/s one) Remove the radiator drain plug and catch the old coolant. Remove the engine block drain plug and catch the old coolant. Remove both heater hoses at the block side and try to catch the old coolant. With a garden hose, flush the heater core "both ways" until the water runs clear. Reconnect heater hoses. Flush the system with a garden hose leaving the radiator and engine block drain open until the water runs clear. "Flush until the water is clear". Once drained, Close the radiator and engine block drains. Fill the coolant system with the garden hose and allow it to purge air for 10 minutes. Turn the heater temp to HOT then Start the engine and bring it to operating temperature. Allow the truck to cool completely. Repeat the rinse again (heater hoses are optional) Close both drain plugs and Fill with 60/40 ratio coolant and distilled water. Start the engine and add the coolant mixture as needed. Check for any leaks. Check coolant levels when the engine is cold for a few days. And that's the way I get a clean system and great heat from my heater (because I know that my heater core is clean) and I know that it's done right. If I can do it, you can do it :)

[@josephmcmonagle5901]

I like that way, but I'll bet it takes a while?

[@FordTechMakuloco]

Yes the hose is best and depending on your water source you may want to use a few gallons of distilled to flush after. The older vehicles are ok and will burp the air pockets but the newer vehicles with reverse cooling systems really should be vacuum filled yes.

The thermostat closes up during the cold water flush. If you are at home and not worried about paying shop hours, then go ahead and close the drain plug during a few drain and fil, wait for temp to go up with the heat on full red, this will circulate the gunk in the heater core and allow it to drain out on the next drain dump.

The owners manual says the cooling system capacity is 24.9L but I only got a little over 8L out of the radiator. So if I do a flush like this that would mean I still have 68% water in the system when filling back up? Should I then just fill it back up with straight antifreeze, let it mix and then drain a little bit more and fill again with straight coolant? Or should I take out the drain plug on the block and drain the whole system that way?
