Very helpful. Thank you for posting

[@anakinbrentley7263]

I guess it's kinda off topic but do anyone know of a good site to watch newly released series online ?

[@jaredhudson8145]

@Anakin Brentley I use Flixzone. You can find it on google :)

[@darielboston6553]

@Jared Hudson Yup, been using FlixZone for years myself :D

[@anakinbrentley7263]

@Jared Hudson thank you, I went there and it seems like they got a lot of movies there :) I appreciate it!!

Man im about to fix all my issues on my impala from your videos. 👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾

[@LemurMonitors]

Good luck!

[@bennieboy2014]

Is there a gasket between Housing and engine?

[@walkerjoggerrunner7571]

😂❤211😊

[@Anon1mous]

A couple more things to add: 1. When installing the thermostat, make sure the air purge hole is in the 12 o'clock position to allow air to escape. 2. Park uphill which helps air pockets escape better as well.

[@mateochistoso3375]

I would like to say thank you for your help, Im a first timer and i followed every step, also I would like to add my 8 year old daughter helped me loosen and tighten the bolts on the t-stat housing, cause my arms are too fat, either way you helped save us tons of money with this informative video..please keep up the good work!

[@keithp115]

I got a Blue Driver for a Christmas gift last year, which has paid for itself over ten times. Thanks to the videos on 2009 Impala's, I was able to repair several issues on my son's vehicle.

[@waltthompson8765]

This was a very helpful illustration it was very appreciated thanks

[@Silonyx07]

Love you guys. Helped me out so many times and saved lots of money.

[@Waas]

Pretty sure my thermostat took a dump on me today. Gauge temp never got close to warm even though I drove extra miles on the way home so I know it was warm. Got an 08 with the 3.9 but the motors are so identical, this video is just what I needed to get the thing changed. Parts are ordered and will be dealt with soon.

[@LemurMonitors]

It's so easy and cheap it's always a first safe bet

[@cameronvisser653]

Just bought a 2010 impala and no heat. Gonna try to do this! Thank you!

[@hectoresandoval8495]

Will this be the cause of “ engine hot a/c off” keep coming on?

[@jpnunezjpn8]

yes

[@jpnunezjpn8]

yes

[@BB-cw3uv]

This what mine doing

[@jamiedtrtruelove7104]

That's what mines doing as well

[@hanriver8838]

Very informative. Helps me a lot. Thank you!

Awesome to hear! Glad we could help!

[@froggymountain]

Spot on. Accurate. Great instructional video.

[@chetmyers7041]

3:09 Gonna need deep-well 10mm socket for the driver's side. 4:35 Is there LEFT or RIGHT on how to mount the T-stat Housing? Bleed hole on new thermostat goes at TOP if it has one.

[@claykrueger8790]

where are the frost plugs located on this engine for adding a block heater?

[@contestsvu4538]

Very helpful video eh. Thanks for showing me how to change my thermostat you hosers.

[@sorrell38]

Good job its was easy to do i will do it myself thank you.

[@b_rad5678]

Did you use any sealant or gasket making material?

[@xxxkybourbonxxxx]

did u add any sealant to the housing on the gasket before u tightened bolts thanks

[@farealwitit7947]

awesome vid! thanks guys!!!

[@clintoncurry4038]

Do you need to unscrew or pull out the petcock?

[@hectoresandoval8495]

So my coolant fans stop working and only work when ac kicks in or disconnected from coolant sensor. Will changing the this thermo work? It still doesn’t blow hot air

[@andrewswensen9966]

Anything about a housing gasket? I took my housing off to replace the thermostat and found no gasket, no RTV, and no leak. Any info??

[@boyugly4096]

Do you close the cooling valve before top off the coolant and start the car for 40 seconds?

[@thisismetv_]

Just got a message on my 2013 saying AC off to prevent engine overheating. I’m thinking it’s the thermostat and going to try this.

[@bennieboy2014]

Do i put gasket or gasket maker ?????

[@electric8668]

First time seeing the 30 sec - 20 sec start stop procedure. Interesting tho my method is different with the heater on hot fan on high idling looking for the absence of bubbles from the fill neck indicating no air in system.

[@roberto9787]

That's what I was wondering.

[@RTR.Lano251]

Is there a gasket yu put on the new thermostat

[@Cize8]

Had to use an offset 10mm wrench to reach my thermostat nuts. Crazy tight spaces

[@mphillips5366]

Thanks guys

2010 chevy impala.LT3.5 liter..Thermostat is on the Lower Hose of the radiator?

[@jimmywalker732]

2011 slow to get heat in cold weather.would this fix it?

[@agapecomm]

Would this replacement fix the AC turning off when the engine is hot? My car's AC shuts of when the engine is hot AND outside temperature is above 90 DEGREES. Thanks.

[@LemurMonitors]

Hello! Unfortunately it most likely wouldn't - one easy thing to look in to would be your ambient air temperature sensor.

[@BSwizzels5211]

Please help. I can't get the hose off to get to the thermostat housing. I moved the clamp but the hose is seized on tight

[@valentinrodiles5983]

Could you do a video on how to replace an AC compressor on a 2006 Chevy impala?

[@LemurMonitors]

Not a bad idea!

[@gregorymcdaniel5197]

Awesome video...just curious...After you replaced the thermostat where did your temperature gauge run? Thanks for the great video!

[@estevansantos6449]

thanks man 👍🏼

[@LemurMonitors]

✋

[@erin19030]

This was the first repair I learned on my first car. It couldn't be any simpler and straight forward. Everything was easy acc so from the top of the engine except the pet clocks on the radiator. These days it takes two people to do the same job and excessive number of tools?

[@AntBoneKLZ]

What year is that impala? Mines is a 09 LT I’m having trouble with my car overheating but I know for a fact I need an oil change

[@anthonygee4157]

My ac works my coolant is full but my needle goes a little above the middle line den it goes back down. .i put a new radiator and thermostat a while back what u think can be wrong

[@eliutparedes4456]

Check temperature gauge.

[@webguy79]

Car is leaking coolant from passer side. And I was looking at videos of old Chevy impala and saw that they have coolant elbow pipes. Are these the same on the 2008 impala.

[@nathanhall4925]

Is the coolant leaking on the inside? If it's leaking on the passenger side floor it's probably the heater core. If it's leaking underneath the car look at the water pump. I had a coolant leak with my impala on passenger side and it was the pump

[@Insanevocalists]

Crossover gaskets. I had the same issue on mine for years till i finally fixed it.

[@SonicKingZillaX]

Thank you

[@danh3013]

While this is a good video it is much easier to get to the stat housing if you remove the battery and its tray then you can get right to the thermostat housing from the side without fighting and scraping your arms on the fan housing from the front. Sure it takes an extra 5 minutes but its well worth the time and it saves alot of aggravation reinstalling the stat and housing bolts.

[@braytonspratt6599]

Thank you so much . I got discouraged doing this . This is my first auto replacement I’ve done myself . I followed all the steps but couldn’t loosen the thermostat housing but and bolt . But I’m going to try removing the battery like you said

[@lilred9302]

Would this be the same for a SS impala? My car won’t heat up at all and blows out just cold air. I’m nervous because it only happened one time when it was cold. Also when I’m driving my car only the side windows fog up at night. Is there any explanation why?

[@jdoc713]

Lil Red I have an 07 Monte Carlo SS 5.3 and am having the same issues. Constantly overheating, replaced radiator, belts, water pump and still overheating. Did you find out what was wrong with yours

[@lilred9302]

JC442 Mines ended up being the water pump and serpentine belt so when I got that replaced everything started working normally. Now I just have to replace the actuator since it’s stuck on recirculate. I would just take it to a mechanic and let them try it out but if you fixed everything else maybe it is the water pump

[@eliutparedes4456]

Fogin window might be vent hose out of place

[@eliutparedes4456]

And over.heating could b a cloged heater coil.

[@FireCracker3240]

My 2006 Chevy Impala is currently having the following issues: 1) Engine hot/turn off AC light comes on after car has only been on 15-20 minutes (and it's winter). Car then stalls. Letting car sit idle for a few moments allows the light to go off and temp gauge re-balances between Hot and Cold. 2) Heat only sometimes (mostly not) 3) Loud knocking behind dashboard when turn from Heat to AC. Will replacing the thermostat fix problems 1 & 2?

[@aprillovesdani]

Replacing thermostat will fix problem 1 and 2 Problem 3 is solved by replacing your bend boot actuator

[@chrisyeary9874]

The knocking noise comginf from behind the dash where the glove compartment is at is the blend door actuator. Removal of dash is required for this repair. As for the engine hot ac off replace the termostat leave battery unhooked for twenty minutes after replacing thermostat.

[@homegoogle3553]

3 is the blend door actuator I replaced this 3 days ago. Super tight space, took about 35 minutes for The one on the far right side

[@roberto9787]

Dash doesn't have to come out but it's tough

[@MRose39]

Would this fix engine hit ac off? My 2008 Chevy impala is pulling that up on the dash. The temp gauge stays at cold and doesn’t move fans run high, no leaks and it’s not over heating. I been told it could be the Thermostat or the temp sensor but I wasn’t sure which one it would be any ideas which one it could be?

[@LemurMonitors]

If the coolant level is good and there's no air the thermostat could be the culprit - one thing you can do to verify this is remove it from the housing and throw it in a pot of boiling water to see if it opens at the right temperature. (maybe don't use your nice cookware though)

[@BEppenger]

I'm leaning towards the thermostat, since I just replaced the temp sensor in my wife's car and within hours it says "engine hot A/C off" on her way to work.

[@kalebjohnson8506]

If that temp sensor opens, is that the high limit doing its job? Vise versa doesn’t work, high limit is broken???

[@southernaire81]

Were you able to fix it?? I'm having the same issue now on my 2008 Impala.

[@BEppenger]

@@southernaire81 After replacing the thermostat, It's the code doesn't show up in my wife's car anymore.

[@a1mike5]

What size 10mm socket? First time trying this noticed at auto zone their are 3/8 1/4 1/2

[@dakotakelley898]

That's just for the connecter to your wrench 10mm is the size

[@pedroj4230]

And if just take off the thermostat ? And no replacement it

[@realtorresidentialycommerc2614]

That location of the thermostat is not where my car has it

[@tpswede]

The video was almost good. It would have been helpful to have some close-ups also.

[@MrJMS814]

You'd need to rip the entire front corner of the car off for that.

Please help! I have the same code P0128. It's a 2006 pontiac g6 3500. It's not overheating. It's not leaking. The heat is hot. It's running at optimal temperature. What could it be bad thermostat are temp sensor? Thank's!

[@firemanpalisades]

Same issue, did you find an answer?

[@Tapoutime79]

@@firemanpalisades Nope, it's my kids car now. She is driving it everyday. It must be fine. Probably still needs a thermostat.

[@peterog6244]

What is the name of the coolant you poured in the radiator?

[@roberto9787]

Dexcool

[@javiergomez178]

They said to turn on the engine b4 putting the coolant.

[@namikojovan1986]

They talked more than they show you what they're doing and it's always the hardest method irritating so is this gasket supposed to stay in the housing cuz they never showed a close-up is this the gas get to the old one or is it's supposed to come out I don't know I have to watch another video thanks what does the mating surface look like originally is it all metal is there supposed to be a rubber ring in there! Or is the rubber ring trash?

[@michaelgraham8788]

Plus the crown part of the thermostat needs to be facing the radiator.. didn't show that...
