Coolant Drain and Fill 2014 - 2018 Chevy Silverado or GMC Sierra 

Wanted to shout you out and say thanks. Recently bought a 2015 Silverado 1500 and after finding your channel (trying to get Carplay), I've been following the rest of your videos (thermostat replacement...etc). These have been a great help and are very insightful - thank you!

I have a 2014 silverado 4.3 slightly over 82k. already changed out the brake fluid to keep it clean and now going to changing the radiator fluid.

Right on ; got my 17’ to do . Was going to check it with Coolant ph strips first. Been through it with 13’ Camaro . Yeah pump was air locked and squeezed top radiator hose while runnning and it finally pickup prime . Scary !!! At least it had a radiator with cap !!! Easier to fill - It’s a can a worms but ; git-r-done !!!- ✊🏻👍👌

I just wanna say I heisted to click on your video (it looked scary lol) but as a girl who was alone and I accidentally put green anti coolant where there was red, this helped a lot and I learned something new :) thanks for being nice explaining this!!!!

Thanks for the video. Getting ready for a freeze and the truck has 84k miles on it so minus well get her done.

Great video sir. Can’t wait for the next video

Always enjoy the videos.

Did you warm up the truck for any amount of time.?Or did you start the process on a cold engine? Thanks..

I got a 2017 Chevy Silverado and now I got check engine and it won’t let me pass over 40 you got a idea how come ?

How much coolant did it take after doing this? Thanks

Exactly what I needed, thanks!!!

Im not going to change my coolant....because i can save money by not doing it....Well to those who dont....you will spend more in the longrun....because once that coolant gets to a certain level of acidity....its going to eat thru your headgasket....not to mention the calcites in the water building up and punching holes thru your radiator(unless you use distilled water) as well and possibly expanding between your head gasket mating surface and head thus causing a leak even if it doesnt eat thru it first....so kids.....change your coolant like dustin...and save in the longrun...good video Dustin....and Thank You for sharing!

What do you do with antifreeze after it’s out does any place take it 😏 like they do oil

Go with Amsoil severe gear for the differentials! 2014 LTZ and I did mine around 65k. Changed all my fluids then. Did front and rear diff, transfer case, transmission and filter, brake fluid. Still need to do antifreeze, but only at 73k today. But I’ll get it done soon. Best truck I ever owned

I just did the coolant flush and fill with my 2018 GMC Sierra 1500 L83 engine, here are some added notes that should be kept in mind when you do your coolant change next. System capacity is 16 litres (for my truck L83), with taking the coolant surge tank cap off and opening the radiator pet cock I was only able to get 5 litres of coolant out in a go. Meaning that I had to then close the pet cock and fill the surge tank with drinking water, run the engine to circulate the coolant and then repeat the process to drain more coolant out. I stopped this drain and refill process after I had drained about 40 litres of coolant, still was getting some pinkish orange even at the end, but it was clean enough that I then just filled the system with concentrate. However since you can only fill the system about 4 to 5 litres in a go before having to dilute it again this involved some calculations to get the concentration correct. What works out to a 50/50 mix is to do the following, drain 3.8 litres from your engine, add 3.8 litres of 50/50. Circulate, drain 3.8 litres of coolant add 3.8 litres of concentrate. Circulate, drain 3.8 litres of coolant, add 3.8 litres of concentrate, circulate and you're good to go! A long process but that's one way to get the job done! The only other way to drain more coolant out of the engine is to access the left side and right side engine coolant block plugs and to remove the heater element, but these three things are basically completely inaccessible so I wouldn't advise, I would stick with the dilution method I've gone with. Hope this helps anyone else out there who is thinking of giving this a go!

No engine block drain as well?

Which engine? 5.3?

Thank you. This helped.

Drain the block?

Did your truck ever have the lifter failure?

Im always shooting my mouth off about ppl on here with long on nothing and a lot of crap to listen to. You got this to where we need it. To the point and done.. got a thumbs up from me and I don't give them out much.. cheers.

Just did mine on my 2014 silverado with 218,000 miles on her

I have seme truck what state do you live in friend

Good video, thanks

Thanks great video

Great video @Dustin, based on your instructions i was able to get to petcock without any tools needed. (from bottom of the truck as well as from TOP of the truck) :) My question is regarding air stuck inside the engine/hose/radiator... i tried to squeeze the hoses after filling the coolant with engine running, however not sure if all air came out, do you suggest to let the engine run for a while with coolant reservoir tank cap removed ? so any air bubble left can come out ? I am wondering if i close the cap the trapped air might not get out ? please correct if i am missing anything.

What about alkaline water ?

Very helpful thanks

thanks for the help.. May 15 2022..😎😎😎😎

thank you very much

This helped thanks

If you tow you will notice cooling system issues over time. My 5.3L LM7 used to tow in summer heat maintaining 188F on a cruise. Over time rust and other contaminants reduce block heat transfer to the coolant. Flush it, you will notice the difference. Also ditch the Dex cool. Your water pump will last longer.

Can you use a fluid extractor to extract the old fluid? Instead of draining it?

under $50? i spent 112 for a 2014 traverse

I have a 2016 with 5.3. Replaced coolant temp sensor for the second time in 2-3 months, fans went off, ac started working, and heat guage came to life. I just got home and as I was pulling in, fans came on, guage dropped, and ac quit. Any ideas? Am I just getting faulty sensors from Oreillys? I even tried to make sure it wasn't some sort of air pocket. I'm ready to set it in fire

Cool 😎, thanks 🫡

Duramax head gaskets and heads such and 15000.00 dollars to change

That 3.5” lift helps I just tried this and was getting agrivated cuz I don’t have enough room stock I’m gonna do my zone 4.5” lift then finish this project I can’t feel around for the pet cock valve not enough room and don’t feel like getting radiator fluid in my eyes takin the hose off

You didn't drain the engine block, so you only replaced about 6 quarts of the more that 16 quarts total in this truck.

Cood!

Good job brother, how many gallon does it need to be filled?

Want to see High Mileage. I Have a 2014 Chevy Silverado 4.3 V6 with 174K miles and Still Running Strong. I wish my truck was nearly hitting 100K

Roughly how many gallons did you take out/put back in from this process?

I like to mix it before putting it in 😏

No flush next time

You do realize that you only changed the radiator coolant and not the block? So are you really gaining much?

Tiptop shape LOL

I prefer 70% distilled water/30% coolant myself, then again I'm in south Texas where it's supposed to be 110 out today.

I've heard you can let your neighbors cat clean up any spills

No don’t agree with the flush thing

Drain plug in block should be removed

these trucks are known for radiator leaks.....every Z71 have had did. On my 3rd truck now...its a 2018. Therefore wiuld not worry about changing the coolant....thats just my opinion. aint broke dont fix

FN'1ST!!!

Appears just the radiator was drained; NO flush of the coolant in the engine. Like doing half an oil change. To do per manual, it needs to be completely drained, radiator, engine, hoses, core. Just another backyard mechanic with poor filming procedures on top of not doing the correct job.
