"Open the radiator drain plug. Be careful not to make contact with coolant." Lol fuckouttahere 🤣

[@Esoteric1987]

😂😂🤣

[@lashlarue7924]

This was a good how-to. Can’t blame ‘em for trying to sell you on their products. For the flush, I’d just use tap water. Then refill permanently with distilled.

[@Patriotalliance]

Should use distilled water to prevent mineral deposits.

[@cccmovers6837]

I know right , dumb asses, never hose water 🤦‍♂️

[@steveslate3601]

Can't believe what I'm seeing!! Bad instructional!!

[@garystrittmater8258]

I totally agree, I think the ONLY TIME I'd use a garden hose is to blow out my radiator with the drain open and the bottom hose disconnected! I think the pressure would help clean the gunk out......but I'm not a mechanic, I just heard an old mechanic say this!

[@mystiqueman366]

@shaocaholica they used a general motors vehicle which used dex-cool. this is gm's "own" coolant and shouldn't be mixed with traditional green.

[@Shagggdude3]

That flush does work good, but as a former srvc tech. I advise going on at least a 15-20 drive at high way speeds, to gain full advantage of the flush product, simply sitting with the engine running is not doing anything.

[@jat-justamaturetech-philpj8285]

I buy 100% coolant and use a gallon container and fill it half with coolant and half distilled water. Closest accuracy for a 50/50 mix. Top of with coolant and fill resovore with coolant cause theirs still just water in the engine. It all works out pretty close to 50/50.

[@brandonwilson6844]

WARNING ⚠️ I used this product for a flush recently , let it go 3 days like the instructions say.... it ate up the seals on my thermostat housing, now I have to remove the entire intake manifold to change seals . 2008 Ford F-150 4.6..... so maybe if you just have to use it, only do the quick flush! Just a heads up maybe it’ll say somebody else some money because it’s costing me a lot of money

[@jonmo2694]

Because of your thermostat housing?

[@fathan16]

this way would take all week to finish

[@iracordem]

isnt prestone flush & fill kit about using a tee & a one way valve to flush the system& i dont see that here…?

[@captainkaveh1]

I did the flushing ,but i forgot to put the water and run it for one more time after i drained the radiator with coolant flush. And just filled it with coolant and water, Is it ok for my car? it won't be any harm to my radiator ?

[@jonmo2694]

What happened? Did you flush it again? I would have

[@MrWontstopthefunk]

So… you overheated your car?

[@jonmo2694]

@@MrWontstopthefunk I think they meant they did not flush all the cleaner out good enough

[@hellohello8556]

Wtf so when you drain and flush the cleaner is still in the block so fill with tap water one full heat cycle empty and fill with anti freeze. So your system will be 50 percent tap water and still have approximately 25 percent cleaner.

[@stephenmckinnon5821]

How y’all going to use regular water instead of distilled water

[@markbuddenborg]

buy full strength and add %50 water, and purchase 50/50, geesh, sell much?

[@franksam6357]

Should use distilled as well.

[@irish89055]

+Frank Sam I guess, if your water is hard with lots of minerals... I'm going to use the hose as our water isn't hard and never had a problem before..

Pro tip- don’t drain orange coolant out of your radiator and replace it with green.

[@garyh4458]

The orange was due to rust.

[@LoveTheFatherAndTheSon]

@@garyh4458 The orange is Dexcool

[@MrWontstopthefunk]

Why

[@bryanthomason8222]

[@Derholeproductions]

The car they are using has dexcool in it not good to mix.

[@michaelblake9110]

+Derhole True, but they are flushing out the old dexcool.

[@LirokuToragi]

This is old, but I'm going to respond for new viewers. When you are doing this flush and filling with green on a dexcool system, you use a "universal" antifreeze that's compatible with dexcool. It's not the same as the original green stuff that causes dex cool to goop, but you should remove as much of the dex as possible anyway, if you are wanting to replace it with this prestone.

[@dr.yahyaelewa1628]

Thank you for your presentation. Disagree, DISTILLED WATER, NOT TAP WATER. Again, thank you.

[@Striker50_]

Doesn't really matter since you'll be draining

[@LTSRIDE24]

assuming you're doing a final fill & drain with distilled water, one would be good, I assume?

Watching in 2021

[@Antithropocentric]

This is incomplete in that it doesn't mention backflushing the system by using Prestone's own "Flush N Fill" kit on the heater hose near the firewall. It's odd that they leave that out. You can't "drain the entire cooling system" by just draining the radiator, especially if the thermostat is closed on a cooled-down engine. The same applies even if the thermostat is open (or removed) with the engine off and there's no water pump or garden hose pressure forcing out coolant against gravity.

[@brentfredrick]

No distilled water?

[@Kolonol1]

Brent Smith garden hose is fine honestly lol...water is water...my flush of my Mercedes consisted of unplugging the radiator completely and running the water hose for 20 minutes...I was also burping an air bubble out of the heater core too...but it also flushed all the crud out...refilled with water and after 2 months of running it was still almost crystal clear...but then I had to add green for the winter :(

[@Kolonol1]

Yes I did flush the radiator separately before you ask...forgot to add that in

[@Jdres123]

chevy uses dexcool,its a red/orange color

[@jimdavidson5208]

Lame video. Says to dump the flush fluid once the temp gets up. Would have no time to circulate in the system.

[@ketobeast8489]

10 minutes after achieving normal temp is good.

[@jimsherman2477]

Ford service manual says to remove thermostat so engine never gets to operating temp. Coolant runs through heater core regardless of temp setting. Heat and cool are controlled by blend doors. Heat selector switch only controls blend door actuators on vehicles with computer processors.

[@shaocaholica]

Why is the flushed fluid always brown? O_o

[@FrenchValleyAirport]

If you own it, prestone it. lol

[@samueltorres7555]

Ugghh... For all of those complaining about color. You never want to mix colors.. true. Diff chemicals MAY be inside. Once the system has been completely flushed and "flushed with water" to ensure your sysyem has been rinsed of the old chemicals. You can use any color that is safe for engines. Including those heavy duty extended life ones used in diesels that run 1000 miles per day. As long as the bottle states safe for all engines. As long as there is no mix of chemicals. Youre good.

[@jonmo2694]

Prestone has a green one that is safe for all colors

[@jat-justamaturetech-philpj8285]

Fail! 1. Never change from orange to green. Stay with original color! 2. On last flush, use distilled water only to flush out tap water. 3. Always use distilled water on final fill with coolant!

[@sonmydful]

Fuck that switch from dexcool to green. As long as you flush your system your fine. Dex is designed to destroy your system

[@LTSRIDE24]

Let me get this correct, since I'm doing this over the weekend. Drain all coolant, add chemical cleaner & fill with garden hose, run or drive the vehicle for 10-15 minutes, let cool, drain again, if water is still dirty, repeat fill and drive and drain process until water is clear. Then, add distilled water to flush out tap water contaminants, drive or idle for 10 or so minutes to get to operating temp, drain one last time. This shouldn't leave any tap water inside the radiator or engine? Fill with 70/30 mix to hopefully come out to 50/50 mix, since there will still be some water in the engine. Is there not a way to get all of the water out when draining?

[@jonmo2694]

@@LTSRIDE24 I would final flush with distilled water

[@tenzackyogi1742]

70% antifreeze with 30%water is good in southern states.

[@RaceDay086]

Wrong... water cools far better than antifreeze as any race motor builder knows. You got it backwards; use 30:70 antifreeze to water if you live in warmer climates (personally I use 40:60 for a little better freeze protection and higher boiling point). The only places in the US that need 70:30 antifreeze to water would be North Dakota and Alaska!!!

[@MikeWrenches]

As a mechanic I must say, this video is very incomplete and gets many things wrong. Vehicles won't have a degas tank and a radiator cap. Draining the radiator leaves much of the coolant untouched. Setting the heater to full and blower to max only slows down the warm up, set the blower to minimum, but this only apply to vehicles with a water valve on one of the heater hoses.. It wasn't back flushed like it should have been. You want to warm it up until the fan has cycled a few times. And more...

[@GenderPranks]

I don't know too many anime loving mechanics.

[@Promethium666]

2:45 you're filling the coolant expansion tank, not the radiator.

[@98770]

except this is not regular green its a Dex cool clone. of course traditional green should not be mixed with anything else.

ju that's why you flush and switch to this, that's what I did
