One thing I would add is before filling up for the final time, I always like to flush the system with distilled water and for sure the final fill mixture should use distilled water otherwise you are more prone to the mineral build up that got you there in the first place. This would be especially important if you have hard water or well water with lots of extras. Great Job overall on the video.

Just did flush and changed out my heater core. Your video is spot on. Took me longer because I didn't have drain catches.

That is the msot throrough flush i have seen yet. Good job

Thanks for taking the time to shot and post this video, its and enormous help. Thanks again, Jerry

Back flush the heater core. Use no more than 10 lbs of water pressure.

This procedure managed to unplug my partially plugged heater core as well. Great tutorial! I would add: Do your best to keep the coolant off of the belts nearby. If it is at all prone to squeal, it may never stop squealing once it has coolant on it. I put a new one on, though, and we are back in (quiet) business.

After this is done you can safely replace your heater core HERE- kzfaq.info/get/bejne/kJySZKqSt7eleo0.html

This was the first time a se e u videos I m one of u many fans great video u give us all the details great grat this morning my wife use the car the heater works and I save money thanks

You're a excellent teacher, follow your direction from this video lord and behold when i pull off my heater core hose there was no fluid in it, nothing were flowing through it, heater core wasn't the issue there was a block in one of those line, I back flush both hoses and heater core and blew through the heater core lord and behold heat was coming through the vents this car never idle at 145 degree 120 was it ide temp now she's heating up like a boss my thermostat opens up at 197 for ford taurus, antifreeze was green as it can be when I drain it i did redo my timing chain gasket it probabbly had something to do the broken up gasket. y car was heating up before took on this DIY job follow your direction from a tee from both of your video not a drip from any area or snap any bolt pb blaster those bolts for a week.

WOW....great series of videos. Problem I most likely need to do the heater core. Before I got the car, it was my mothers, and it sat for about 6 years, only being driven maybe 10 miles a year to get it inspected and such....So even though the car only had 45000 when it was 11 years old - it had a lot of problems that high mileage cars get. anyway - my question is If I backflush the system, and replace the overfill bottle and do a themostat for good measure since it really is easy access, If I have to wait a month or so, to get time to do the heater core - will the core in the mean time muck up the new fill tank? and need to replace it again?

Thank you. This was a very informative video and easy to follow. Car maintenance has always intimidated me, to my car's detriment, but this demonstration has showed me that I can do it myself.

Did you turn on the heater during the flush?

Also for heater issues make sure you block the bypass hose with hose pliers otherwise it wont heat even if you do what you did in this video

On some Tauruses, 2002, 2003 if I recall, there is a "bypass" hose in the metal coolant lines near the core. Appears as if it is there to provide a means for coolant to still flow around the core instead of through it if core becomes restricted. We will pinch this hose off when flushing to get full flow through the core. Still an annual procedure, have not tried the chemical though, will try to do that next. Thanks for the great videos!!

Thank you so much

You repeatedly reference that the coolant is warm and/or hot and the thermostat is open, but I can plainly see that the alternator isn't spinning at various points throughout the video. Did you start this job when the engine was hot and are just using the residual heat (can't imagine that would last even ten minutes while running cold hose water through the system), or are you using some other heat source? Is your hose connected to hot water? What's the water heater set to? Most water heaters don't go over 130F or so, and most thermostats don't open until at least 180....

Thanks for all your Ford Taurus videos! I have a 2001 and 2007 Taurus both with the Vulcan engine. Per their owner's manual they have different spec coolants. Was wondering if I should use the 2007 spec coolant in the 2001?

I got a prestone backflush kit which is a plastic "tee" fitting that comes with hose clamps and a cap. You cut the 5/8" or 3/4" rubber hose which runs between the top of the water pump and the heater core and install the tee with clamps. there is a garden hose attachment so you can attach the garden hose to your heater hose. Open and remove the overflow canister cap, turn on the hose, start the engine. The rusty water/sediment will be flushed from the core and out through the overflow canister top. I also use the chemical flush once I've flushed with water, then rinse system one more time w/ clean water. Once a year keeps my heat going... Good luck!

Thanks for vids. So I have the smell in the car of syrup. From past experience I know its the heater core. I find no water on the passenger side of the car. I don't see any water on the ground, yet I'm "missing' water from the coolant bottle. The car blows hot air. Doesn't overheat. If the core hasn't gone bad, would a flush do it well? If I'm smelling this, is it too late? Thanks for the vids. They are great. More than willing to give this a try with all the help I've found here. I'm no mechanic, but for the costs of repairs anymore, I'm getting better at it!! Thanks again!

Does this video show "back-flushing" the heater core?

Would this process work for a 2004 Taurus with the 3.0 v6 DOHC 24 valve duratec? I just need to drain the radiator and put 50/50 in it. It has water in it right now.

damn real through, thanks!

Did you need to take a large piece of plastic off to get to the drain plug?

How about isolating the heater core, pull water out with a vac and soak the core with CLR overnight? The block had been flushed and still low heat. Flushing it alone has worked but it's bad again.

I asked for your experience I replaced the heads on a 98 Ford Taurus with a 3.0 and the reservoir put a new thermostat in it flushed the heater core before I put the engine back together both directions now the engine runs at the temperature where you show on the video and I used a OBD2 that would hook to my phone and it says I have 188° water I have 192° thermostat in there but I don't get any heat I have 180° thermostat that I'm thinking about changing is there any other secret way to get all the air out

Would this work for flushing the radiator on a 2009 F150 5.4?

I have a 1999 ford taurus se and will have the same problem that does not heat. And I have to do that to my car

I had an issue removing the overflow reservoir with the rear 10mm bolt not coming out. I removed the passenger wheel and the wheel well shroud and found the bottom of the bolt spinning freely when I tried to unscrew the bolt. I tried holding it with pliers but eventually just heated it up and punched it out. No more bolt back there, but it's a plastic bottle and is attached two other places, it's not going anywhere.

Great video. Thanks for posting.

thanks very much

Collect some of that for added milkshake flavoring.

Im going to service my cooling system on my 02 Sable 3.0 vulcan. Most likely replace the heater core. Is there any chance the VC9 could cause damage during my flush...eat away something? My coolant isnt exactly rusty. Also, and recc on Zerex G 05 for coolant or do you swear by the VC 7B? Love ur vids btw... !

I have a 2005 Taurus and had a thick orangish substance in the coolant reservoir most said it was a head gasket I had a mechanic pressure test and it held fine now no heat so I assume some of that crud migrated into the core.

Do you think that someome with little to no training (other than this yourube video) can do this?

me again another great video so hds are in eng all buttoned up nothing left over and i was wonedering i want to flush i am in az so what thermastate 192 .180,or 160 degree should i use and should i put in before flush thanks

Hey my coolant is turning brownish or black in my overflow checked oil oil is fine not milky but could I have to flush my radiator out to

Hey man thanks for these videos and I hope you're still checking comments? I did this flush today on our 01 (I already changed the heater core a couple years ago and the heat is still working just fine) but was wondering if you would recommend pulling the hose underneath that goes into the radiator as part of a flush? I've pulled it before but 1) it was a pain to remove and 2) not sure it was even necessary to fully flush. Are you still of the mind that what you've done in the video is enough? Thanks!

check the water pump on that thing and a belt tensioner

Could you use some pb blaster or rust remover in a radiator to help flush the rust?

He cleaned tf out that coolant system 😂 he had the hose inn it for a mean minute i be scared of ruining a gasket. I gotta do the waterpump and Thermostat at same time to be safe

WHAT CAN I USE TO CLEAN OUT ENGINE BLOCK IN HOAT DIESEL MOTOR? FOUND BROWN GUNK AND HAD PLUGGED HEATER CORE. LOWER RADIATOR HOSE IS HALF WAY UP RADIATOR ARGGG. SEALED SYSTEM I MEAN TOUGH SUCKER WORK ON AND THERMO IS SPECIAL 200 UNIT. COULD I HOOK UP TO MY HOT WATER HEATER AND RUN IT? TINKERING USING PURPLE POWER,CASCADE DISH WASHING LIQUID OR SIMPLE GREEN, VINGER,ZEREX HEAVY DUTY CLEANER, USED PRESTONE FLUSH AND NOT GOOD ENOUGH.

Awesome video, Thanks for taking the time to post this. I am going to be replacing heater core ( which is totally blocked w/ rust on one of the tubes), coolant reservoir and I'm afraid I need radiator as well. When I remove the plastic drain plug, all I get are a few drops of coolant coming out, even when engine is hot. When I drain by taking off the lower radiator hose at the radiator, I was getting lots of tiny rust particles before I flushed with Prestone stuff, running clear now but still nothing from the plastic drain plug. Would you recommend still using the VC9 cleaner being that I'll have new radiator, heater core, reservoir and if so, should I VC9 flush before installing new components or after?

Everytime I put water in it and if I let my car run for 5 r 10 mins it start to overflowing and steaming what that mean

So does your shop have some sort of drain system that collects all the old coolant and cleaning chemicals?

Do I need to do this to just replace my thermostat? My car isn't putting out much heat in the winter, so I got a new thermostat, and I see that this is for replacing my heater core, just didn't know if I needed to do this for just replacing my thermostat.

How long do you let the rust flush cycle for? And can you remove the coolant reservoir and clean it out would it make a difference ?

6:20 Why not check if the heater core now produces heat, before refilling with antifreeze so it's not wasted if u find out that heater core needs to be backflushed separately?

I'm having heat issues with ford taurus vulcan engine. The car heats to normal temp and will not blow hot air at an idle even if the engine is warm. However, when u drive the car or rev the engine it blows hot air. Where should I look first? Could this be an issue with the blend door? Or is it more than likely the system being clogged up?

Did you remove the thermostat to flush or leave in place?

What about the water thats left in the engine. If its supposed to be 4 gallons of coolant then. When flushing with water, there are two gallons of hose water left in the engine. But we are supposed to use distilled, how do we fully empty it out?? so we can add 2 gallons distilled water, and 2 gallons straight anti freeze

I had someone put engine sealer for a head gasket leak, which supposedly turned into a cracked head on my 2002 Taurus. I am going to replace the cracked head and redo all the gaskets required when doing this, but I was wondering if I should use this same method (as in the video) to flush the engine sealer out of the cooling system, but with a different chemical, before I replace the cracked head? I don't want the engine sealer to harden and clog everything up, but I'm also worried about the cleaner getting in the engine if the head is cracked? Any suggestions or advice is greatly appreciated!

Ive got a 2000, 3.0, no overheating, no pinhole leaks thst i can find, as soon as it warms up it will smoke from engine bay, towards passenger side. As best as i can tell it has no leaks around head gasket. Possible timing cover gasket?

One more question...how long do you run the engine with the VC-9 poured in?

When you were flushing it with the car running was the drain plug unplugged or plugged? Thanks

Can t find WHERE to put antifreeze..please help 😣

So all it takes to bleed the air out of the system is run it with the cap off till its hot and keep the reservoir full?

Couple questions: 1.) Is hose water OK? I've heard distilled water, does it matter? 2.) I've heard that some Ford Taurus models have a by-pass valve in the back that is part of heater core system. Is that something I should bother with for normal flush?

FordTechMakuloco I'm going to change my radiator. Should I flush before or after changing it?

Are there other vendors that make a rust flush chemical or does it have to be the ford branded one?

Does this video, and the heater core replacement applies to 2002 3.0L v6 single cam mercury sable as well?

are these plastic drain plugs replaceable? can you buy them?

Did the heat work after the flush ?

I have a 2000 ford Taurus. I have no heat in the car and there is some type of fluid on the passenger side floor. Would you recommend me getting a coolant flushing. I was told to wait to get it done in warmer weather.

i've done this on a few 6.0l's the block plugs do make life easyer:P passengers side is a bitch with the starter in the way but you can get around it with the right socket^^

Damn that bad with only 76,000 miles on it

what's the best antifreeze for 2001 E350van 7.3 diesel

inter summertime just fill it with water driving around for a couple hours do your chores running your errands then go home and flush it again and then the next day maybe got to go to work put some new water and there one day you know plus it around it it'll be alright in the summertime

i have a 97 taurus and im running into the same thing. weird thing is while im running water into the overflow container and i have the radiator plug open at the bottom, there is no water coming out of the radiator. so that tells me theres no coolant/water going to the radiator at this point. would it be my upper radiator hose that needs to be replaced or what?

what is another dark green coolant I can use besides the motorcraft coolant for a 2010 ford fusion

i replace the radiator n i saw this brown stuff on the hoses i put everything together n i put the new coolant in then i noticed the coolant turn brown like rust si i dont know what to do any help

If I shut my heat off for a bit and I put it on I get a little heat I replaced my thermostat and same thing my mechanic keeps telling me it's that could it be the core

tell me if someone mixes gold color coolant too the old green type coolant and it clog cooling system. can you clean it like this?

is it ok to run that cold water into a hot engine or are you letting it cool in between?

Hey, I have a 2002 Ford Taurus and I get no heat at all, no air no nothing its just dead, could this be part of the problem?

I have question. My Ford Taurus overheated and won't start. Where should I start, mechanic said fuel pump, what!/?? Is that right

Will these procedures work the same for a 2002 sable? Bought a used one and the core is bad too damn expensive to have a pro do it so im gonna try to do it myself.Also besides the flush and changing the core is there anything else that i really need to?

this almost seems like the same procedure for the 2nd gen ford taurus from 2011 to 2017 with the 3.5 to 3.7 engine.

I'm no mechanic but isn't the icon on the overflow tank saying not to fill it with the color your putting in?

So on the Taurus (mine is a 02 LX 3.0L U code), there is not a radiator cap that allows you to fill directly into the radiator?

how do you do this with no radiator cap. I only have a reservoir bottle.

Where do I put the water for my ford Taurus 2001?

How do you tell which engine is in your 2000 Ford Taurus SE? I'm asking because there is no real identification on the engine other than the 3.0 L. VIN number 1FAFP53U6YG110867 I'm asking because I recently purchased a Taurus and while looking for parts... well there are choices: 6 cylinders 2 3.0L Flex fuel OHV 6 cylinders S 3.0L EFI DOHC 6 cylinders U 3.0L EFI I'm guessing it's the "6 cylinders U 3.0L EFI" because there is no 2 or S in the vehicle identification Number. The car has 160,666 miles and yeah I wanted to do an overhaul on it this spring. Car runs great but did notice the rust in the coolant. That and it slowly loses coolant. "About a gallon a month" was the line I got from the previous owner.

really hard to remove the under radiator splash guard especially the last nut - any one have tips? It's got a nut outside and one behind it I think one is 10 mm and the other is 11 mm

I know you recommend the VC9 but it's rather expensive and I don't want to wait for it to ship from Amazon. I just got a bottle of Prestone's "super flush". The label says you can leave it in while you drive around for 5 days or so. Is this safe to do?

So just curious. At 7:58 the tank has a sticker with an icon that looks to be indicating no orage coolant, but you suggest orange coolant in your video description. Am I misreading the bottle sticker? If I fill my 97 Taurus with Orange coolant, will I mess it up?

According to Ford/Motorcraft "do not use this product to flush cooling systems where the cylinder block is aluminum" What would be the difference between an aluminum cylinder block and a aluminum cylinder cylinder head?

Would this also be the same procedure for a 2008 Taurus X.

did you get heat back after this proceedure?

you never tested the heat after word on camera

thanks for the video, only thing that annoys me is you are just letting all the coolant flow on the ground lol

Is this normal in these cars?

Where is the drain plug under the vehicle?

Lmao read captions on 9:13 😂😂😂😂😂😂😂😂😂

Are you using low pressure? Obviously my guy didn't do it probably on 99 Marquis sedement was still around container! What was done wrong? I don't think he used a iron cleaner,+ I asked him about using hose he said he couldn't, can't remember why.

Mechanics charged me $1,500 to replace my heater core but only did a coolant flush . These guys even stole my change in the ashtray .

It doesn't matter what u do to flush this car. This car has a time limit till death. Flush flush flush all u want. Replace the radiator, water pump, heater core, then head gaskets. Repeat! Best thing u can do with this car is sell it!

Sure he used apan to collect.

You are supposed to use green antifreeze not Yellow....
