Thanks for this video. Made replacing the coolant bottle easy. Didn't even spill any coolant.

[@pooh101g]

Thank you so much. I've asked people to help me over and over. Thanks to your video I figured out the issue, and was able to fix my suburban. Thank you so much.

[@stevan1023]

Great video. Took me about 30 minutes to replace mine. 👍 now I have to figure out a few more repairs.

[@tijuanabajacalifornia4680]

Thank you very much, I have been following your videos and I have been very happy with the results,I'm not a mechanic but the way you guys explain and videotape is very good, thanks again and God bless you all.

[@dillon2911]

These videos are always great. I've fixed alot of stuff on my Silverado from watching them. Only thing is I wish you guys would explain what caused the problems and why it had to be replaced. I was sitting in the parking lot at idle and all of a sudden my resevoir started spilling over

[@1AAuto]

+Dillon Thanks for the feedback!

[@luissonoma6255]

Where does that bottom hose attach to, is it part of the Heater Hose Assembly? I'm trying to bypass the heater core with a u-shaped line at the pump since it's leaking and don't feel like ripping the dash apart to replace the core but not sure if the reservoir is linked in there somewhere with some sort of Y-shaped hard plastic piece.

[@whiteboy7604]

Does anybody know where i can get one of those plates that was under the airbox haven't been able to find one and i dont know what its called

[@LuckyTrigg19xx]

Hey would the harness not being there cause a leak?

[@danielbeaty6215]

Great video. Do you sell just the coolant level sensor or do I have to buy the whole tank?

[@johnkozlowski7642]

Thank you so much I replaced the radiator overflow tank my self today your video is very helpful.

[@efrainalonso6080]

The wire connector to the bottom of the tank where is it coming from? I got a 2000 Silverado and it’s missing the wire connecting of the bottom of the tank? Helps guys

[@bigglooni3573]

I like the videos they are very helpful, but are there any videos on how to remove and install the coolant tank (water reservoir) on a 2006 Chevy Impala LT 3.9 engine? I could really use this video a lot, thanks.

[@1AAuto]

+BIGG LOONI3 We're always cycling through common cars. We'll add this repair to our list! 1aau.to/m/Shop-1AAuto-c

[@johnkozlowski7642]

Could you reuse the coolant in the old radiator overflow tank or dispose of it properly?

[@abdullahalajmi4724]

Is there any problem If i put water in radiator ?

[@NicoleMarieConley-wj6jk]

It's also just one more hose clamp to completely remove the air hose so you don't have to fight it at all.

[@saelee33]

Why are you guys replacing it for?

[@carterhanson1232]

What is that harness for on the bottom of the tank?

[@1AAuto]

+Carter Hanson That is for the fluid level sensor!

[@larryevans9494]

The new overflow tank I bought has a plug on it my overflow tank did not have one does this matter

[@1AAuto]

+Larry Evans Thanks for watching! It sounds like the one you ordered has a low fluid sensor, which some vehicles have. If your original does not have this plug then the new one will not work.

[@noeehhg.864]

1A Auto: Repair Tips & Secrets Only Mechanics Know is it common for a vehicle to not have the tank with the sensor in? mine has the plug but my tank does not have the sensor it’s a 2006 GMC Yukon

[@ricarditovazquez3126]

So If it's overflowing I must replace it?

[@famousgrice8518]

???

My 2001 silverado 1500 v6 my engine started to act up today , i popped the hood to take a look , i noticed the coolant reservoir empty , i then filled it took it for a spin , i came back n checked again and the reservoir was empty again , then checked my engine oil dip stick the entire stick was toped off with oil mixed with water, no my truck was not overheating it started to stall and just turned off ? Wat could cause this and fix it

[@1AAuto]

+Jose Soto Thanks for watching! Unfortunately if you have coolant and engine or transmission oil mixing that is not a good thing. We recommend you have your vehicle towed to a trusted garage and have them take a look at how extensive the issue is. 1aauto.com

[@josesoto9099]

Alot of freind of mine are suggesting i get the motor swapped insted of repairing the heads because they say the egine wont be the same even with the heads repaired

[@texascoastwandererkayakfis672]

Sorry to hear about ur silverado..did u find problem ?

[@texascoastwandererkayakfis672]

Sorry to hear about ur silverado..did u find problem ?

[@theactualdarthvader]

put a 6.0 in it bro lol

[@lucasa4442]

Does anyone else not have a sensor for their coolant tank???? My truck literally does not have one (2005 Silverado 5.3)

[@saelee33]

Sensor is on the bottom of the tank. I have it on my 2003

[@User8571]

Heater hose is cheap. No reason not to swap them out while you're in there.

[@daz4312]

Hmm… you can actually do this fairly easily without removing the air box…

[@collumnjaffar750]

Why would you change the coolant overflow tank

[@1AAuto]

+Collumn Jaffar These can become cracked or warped due to age and climate of where the vehicle is kept.

[@mikeanderson1994]

Why are you shaking !?

[@dank9411]

No
