If my radiator got replaced last year and water pump 2 years ago what could be leaking lots of coolant? If I crank my A/c up it'll leak even more quicker...

[@Guido19]

@@johnnyrodriguez276 hmm sounds like it could be ac related. How does your ac work? Is it for sure leaking coolant or is it refrigeration?

[@ForevaThero]

Mines leak from the drain plug it’s self at the bottom what should I do???

[@Guido19]

@ it’s probably just the oring that’s on the drain plug that needs to be replaced. I would just get a whole new drain plug if it was me. They are like $6 and that will insure it’s got new threads and everything. I replace my drain plug every other oil change

You nailed it! Appreciate the shout-out as well!! 🍻

Thank you! No problem! Impala gang!🤝🏻

I’ve got 2012 Impala 3.6l with 300,000 and still runs like new.

[@bradmccoppin2194]

Hello, I have a 2012 impala with 3.6l. If you look at page 12-2 in your owner's manual, it tells you fluid capacities. The cooling system is 9.1 qts. When you drain the system with the petcock you only get a gallon out, so you still have over a gallon in the system, that is why I put 1 gallon of distilled water back in and drove it, to let it mix and drained again, I repeated these steps until the water was clear, then I put in 1 Gallon of full concentrate Dexcool in, not 50/50, and if you need to top off the system then you can use 50/50.

[@extremeinternets]

Your video is spot on, you'll get about a gallon out through the petcock. I figure if you change out a gallon every 2-3 years you should always have reasonably fresh coolant. And you're right, it is self bleeding, that's what the small hose that runs from beneath the ps res to the coolant tank does.

great video! love seeing you work on impalas

[@Guido19]

Thank you!!!

[@terrygloa7925]

Thanks for the video! Everything was the exactly same on my 2013 Chevy Impala LS 3.6. The only exception was it took about 1 1/4th gallons of coolant. I let it drain for close to two hours, it kept dripping which didn't look like much but I suspect that's why it took a little more. Mine has 46,000 miles on it.

[@GalvanJ7000]

Love the chrome caps n chrome bars nice 👍

[@fredkuhn165]

So since you only changed half you should drive it awhile then do it again. Then again every 2-3 years unless you get all 2 gallons out. You can disconnect a heater hose and blow air in one side to push some out there.

[@aaaaii6511]

I love all you videos

Thanks for making this video super informational

That’s a nice engine 👍❤️

Mines is leaking from the little twist thing you just showed

[@Guido19]

@@NorthMex you might need to order a new twist plastic plug or oring. They are cheap on rock auto

Bro your engine looks great how u got the support bars chrome

[@HuskerRed11]

Great video. I have a 9th Gen 2016 Limited LTZ. Any idea on how much coolant I'd need for a flush? I have a shop near me I can take my cars to & he'll do the labor, I take the parts to him. So wondering how many gallons I'd need to get. Also what kind/brand of headlights you running? Look like LED's. Thanks!

[@Guido19]

@@HuskerRed11 I would say around 9 quarts as that is the coolant capacity that the impala holds. You could probably drain it like I show in this video and run distilled water and a cleaner if need be but I’m not really a fan of those and then just drain it again. My headlights are the auto one brand. They are super bright

[@HuskerRed11]

​@@Guido19. Cool. Thanks!

[@LionhartM]

First coolant change I've ever seen where no bleeding procedure is shown. Do these just not need it?

[@Guido19]

@@LionhartM yup! No need to bleed it! The way the reservoir is designed the system will bleed and burp itself

[@LionhartM]

@@Guido19 Okay, I think I remember learning that years ago, but I forgot lol. I'm so used to older cars

[@aaaaii6511]

Dex cool 50/50

[@Nwtd_]

Any suggestions for drippage on the overflow cap side?

[@Guido19]

@@Nwtd_ is it dripping for the cap or the rubber line?

[@snipestavo9616]

I am a mobile mechanic. I just did a radiator because it was cracked on an Impala yesterday. I ran the car for about 40 minutes with heater on blast to let all the air burp out now the customer is calling me back saying it’s still overheating . I was having my doubts that it could’ve been that I did not bleed correctly, but after watching this video, I know I did my job correctly so whatever is causing it to reheat it’s not anything that I did. 😅

[@Guido19]

Yeah most likely there’s something else wrong with the vehicle possibly water pump or thermostat. On the 2012+ the reservoir has a self burper so it burps the system itself

[@snackwad1952]

@@Guido19wait so there’s no bleeder screw near the radiator? I just watched a video where there’s a bleeder screw

[@Guido19]

@@snackwad1952 hmmm not of my knowledge but there’s no need to mess with it as it burps itself

[@extremeinternets]

Here's what happened- they lost their coolant, overheated it and blew a head gasket and now they're trying to blame it on you.

[@John115Yonkers]

Let it run with the reservoir cap OFF to burp it.

[@Guido19]

No need! The reservoir on the 2012 impala’s automatically bleeds and burps the system with the cap on. If you watch the end of the video the exact amount of coolant that came out went back in

[@shaunvalencia2644]

My 2012 Impala gurgles sometimes at engine start would it be a bad idea to run it with the cap off in case there’s trapped air?

[@NorthMex]

50,000 miles pffft, she’s not even broke in yet haha, my 13 has 160k and it just had the coolant replaced bc the radiator busted due to classic GM plastic, other than that I haven’t touched the motor in any major mechanical way lol.

[@Guido19]

@@Dlri haha!!! Right I know I gotta keep that maintenance in tip top shape

[@lasellebell1432]

Could you give advice my car is leaking coolant

[@Guido19]

It can be anything! I would get the car in the air and see where the leak is coming from! Could be a bad water pump! A hose! Cracked radiator! Anything so I would try to find where it’s leaking from
