I enjoy the whispering aspect of the video, it makes me feel different inside

[@ItsOutlaws]

That’s called ASMR bro. Look it up on KZbin, there’s many more videos with the whispering

[@2carpros]

Awesome, thank you!

[@ericwilcher4843]

Great video! It help me service my radiator my self. After you drain you may want to run some water and/or solution through the radiator get get rid of any debris. It only cost me $10 for the coolant.

[@markcotter4213]

easy job! my 02 suburban does not have an air bleeder so this video applies to my needs. I did replace my water pump but still, this video shows how simple this procedure is to do.

[@losmoore3358]

Can I use the same drain pan that I use my oil changes with ?

[@franciscohuerta1780]

I have an 06 gmc yukon..im going to replace the engine coolant..1 gallon of dex antefreeze..with 1 gallon & water do it..or do i need to put dex antefreeze olny?

[@mongosafariadventure]

You like it messy. There is a drain hose right next to the drain plug .

[@diegosaucedo2926]

Thank you for the video it helped us out a lot.

I have a 2000 Chevy Silverado 4.3 v6 and wanted to change my coolant there is still coolant inside the tank but I unscrew the cap off the tank put a drain pan under and unscrewed the screw from the radiator and no coolant drained but I looked back at the coolant tank and some coolant was gone what could this be?

[@liljosessj5]

Thank you for the video

[@kristopherjohnson5782]

I can fill mine at all.. I put some in the block itself to prime the pump then I filled my reservoir and started it with the Heater on and no fluid moves.

[@Twinjeremy]

My radiator has no drain plug where you say it is... it looks like a dummy drain plug? idk wtf is going on.

[@SteveZ-yd6em]

Why are you replacing the coolant cap and the radiator cap? Why not just re install them?

[@R0CK070]

2003 Suburban Do I need to flush out and re add fresh anti freeze. 1. Blower motor runs high on 60 when increasing it goes low. 2. After running idle 20 plus minutes my reservoir loop warm. Any clue? 3. Both heater core hoses are hot. Any help would be appreciated.

[@R0CK070]

Actually is working after I ripped into system. It was the stupid selector button on the controller got switched... 😆

[@abrahamfisi8512]

Thanks for the video.

[@zjedinite]

Good video for a “ quickie “ but this ain’t no SUPER FLUSH snap snap lol I disconnect the top hose going into radiation, I stick a garden hose in radiator then flush. Last flush I use distilled water and then blend my shit up before topping off.

What number was the drain plug

[@thatguy_jose]

So if I go 2 gallons of full concentration.. do I need to use 2 gallons of distilled water? Making it close to the spec of 4.25 gallons?

Yep. Thanks for watching!

thank you for the video very helpful

[@alisaleh4758]

If you dont want problems dont touch the coolant system leave as is once you drain and refill problems will start from water pump problems to leaks and gasket again if u not having problems dont touch it

[@jameslewis3357]

I own a 06 Sierra with a 6.0 same set up as this. And you 100% have to burp the system, that have two purge valves, cause guess what, my thermostat will run high every now again, indicating I have air in my system .

[@2carpros]

Did you allow the engine to warm up to operating temperature when you were filling the coolant system with the radiator cap off?

[@olenaerhardt7725]

2003 Chevrolet Cavalier has that engine coolant drain plug, but I can't find it. Do you happen know where is that drain valve located? Thank you.

[@2carpros]

It will be on the side of the block just above the oil pan flange. Thanks for watching!

[@olenaerhardt7725]

@@2carpros Thank you, I will look. Maybe you can also tell where is the bleeder screw on that car to release air from the system?

[@olenaerhardt7725]

@@2carpros I looked at that area and couldn't find. I understand it is somewhere around the oil pan. Is it more to the front, to the back, to the side of transmission, to the side of passenger wheel? I saw one bolt (same as bolts which are attaching the oil pan, #10mm), it is located higher than the oil pan bolts, very hard to reach, maybe w/a deep socket. I didn't try yet, but afraid it might be the wrong bolt.

[@mikebaker9313]

how much coolent does it use I have a 01 Tahoe getting ready to do a new thermostat

[@Des420]

Just under 4 gallons.

[@chalkyeye5956]

Ok what if my heater core hose broke last night and I only replaced that certain part would I still need to keep the cap off and wait till it reaches temp? It's raining and cold I waited 30-40 minutes and it stayed at the bigger line above 160 didn't go up till I capped it but now my oil gauge is going up to 80 as soon as I receive the engine what did I do wrong? Or what can I do to correct this??

[@Shanonmcnab576]

You always keep the cap off with the engine running while filling. Oil pressure gauge has nothing to do with coolant hot and cold gauge. Oil pressure gauge could be faulty/ sending unit or you have too low of oil or you filled the oil up too high or something internally in your engine could be wrong or maybe you have an oil leak. Most of the time the sending units are faulty or theirs an oil leak. If your engine runs smooth and quiet it wouldn't be internal.

[@Helmuesi911]

Your oil pressure sending unit is bad

[@MakeItMike]

What about the coolant in the engine heads and block?

[@jand8303]

Stop it

[@breadwinnerkane9661]

2005 silverado dosnt have a drain plug. Do I just pull the hose off the bottom of the radiator and let it leak out?

[@2carpros]

Yep that works. Thanks for watching!

[@jgehbinv]

On a 2004 Tahoe, where EXACTLY can I find the drain plug? Your video zooms in too closely to the plug and because of that, I cannot determine if it is on the center, driver side, or passenger side of the radiator.

[@taylormaughan7428]

Looks to be on the passenger side where the radiator is. 🫡

[@samsen201]

Thanks for your effort in making this.Not sure if this is the same on other GMC models as I am searching to find this flush for my Denali Yukon XL. I lose my orientation when you show the "Drain Plug" at the bottom of radiator. Would be good to either zoom in from a rough full view of car, to the location or at least say if it is located in Passenger or Driver side/ on the bottom or side wall of radiator, or any other obvious reference. Also is there a problem if you make the 50 / 50 dilution in a separate container and add it when mixed and in correct dilution? The way radiator is to be filled or air trap to be removed, is not well discussed / shown here.As most YT clips, a higher level of sound would be nice and your video quality is much superior to most. Thanks again.

[@2carpros]

Sorry about that! It is on the driver's side at the bottom of the radiator! It will be the same for GMC models. You can dilute your coolant mixture in a bucket or something and pour it in yes, as long as you get the mix correct. As long as you fill it to the line in the reservoir, start the engine, the amount will drop just add some till you get to the line. Let the engine warm up and just keep adding when you notice it is dropping you should be good. An other good idea is to keep checking it over the next couple days all the air pockets will have worked their way out by then. Thank you so much for watching!

[@sthier24]

Drivers side or passenger side?

[@skrillywilly9621]

Where does it show the line u gotta fill it up to?

[@2carpros]

It is on the side of the reservoir. Thanks for watching!

[@alex.3.kitsune663]

In my experience it’s a pain to see. There is a seam somewhere near the middle of the reservoir, and the fill line is just above that. I typically have to jiggle the tank in order to better see where the liquid level is

[@oouu-nq1mv]

Can you do one for a automatic transmission change

[@dragonworld2008]

Why you did not bleed the air bubbles out ? This way you don't have to keep checking it .

[@2carpros]

This system is self bleeding once the engine is warm

[@Purechaos61]

Where would the petcock be on a 2006 Chevy Tahoe? I can’t find mine.

[@donodom3441]

Some don't have it. I just discovered my 05 Suburban doesn't. It can be messy, but remove lower radiator hose to drain. I did it from above easily after removing the hose contraption between air cleaner box and intake. I'm changing belts and hoses in preparation for a trip so it's no extra work for me. Dumb design though.

[@Helmuesi911]

You can’t find your petcock? Did you look really hard?

[@matthew65536]

can you show me where to find a video on flushing and putting new coolant in a chevy S-10 model year 2000

[@aldofrausto1637]

Matthew Berry it should be a bit similar but if you can't find any help just disconnect the lowest radiator hose you have.

[@B_HarTz]

Matthew Berry want me show you a video of how to pump gas too?

[@danimal7474]

Why didn't you use the drain hose right next to the drain plug

You are welcome

[@manny18zl15]

Is it bad if you only put water in it ?

[@2carpros]

Yes do not only put water in the cooling system. You need to use a pre blended mix of coolant or get the concentrated stuff and add the water yourself. But do not only put water in.

[@GodWasAnAlien]

Question: I'm swapping out distilled water for antifreeze due to the onset of cold weather. I just got the Yukon and changed the radiator about 2 weeks later when it sprung a leak, kind of kicking myself for not just putting antifreeze in back then, but it had really old dex fluid in there and I wanted to flush it out before I put regular in. I've heard running bad dex in there for long enough can actually crack your head. I've got my reservoir full of antifreeze and I'm about to drain enough out of the radiator to concentrate up, but the car never actually seems to get to 200F so I'm wondering if the thermostat ever actually opens to let the antifreeze circulate through the engine. Can anyone shed some light on this for me?

[@mdlee52]

The thermostat opens up before 200 degrees. 186 degrees

Check your manuals because distilled water should not be in these engines. Tap water

[@monteclark1115]

The manual specifically says distilled water. NEVER use tap water in ANY radiator

[@Helmuesi911]

@@monteclark1115 Actually I’ve read the manual.. it says clean drinking water.

[@monteclark1115]

@@Helmuesi911 I don’t know what manual you are reading but it’s wrong. I have a manual also and it says 50/50 dexcool/distilled water. Drinking water contains minerals that will cause mineral deposits to accumulate and clog the radiator. Tap water often contains chlorine which will oxidize steel and aluminum parts.

No simply start the engine and allow to warm up to operating temperature with the radiator cap off. Add coolant if needed.
