2007 Chevy Suburban Heater Core Replacement

Guys here in this video we are replacing my heat core in my 2007 Chevy Suburban. I hope this will help some of you guys. I hope you enjoy. Thank you for watching.

[@adrianmendez3451]

Thanks for the video, attempting on a 2009 Avalanche. Windshield was fogging up and smell of antifreeze, no leaks at all, I also found its a sealed system, no cabin filter. It was a bit dirty but not bad. I'm doing a flush first before trying the replacement.

[@michaelyoucanfixthat]

That was the same thing mine was doing. Yep it's that time for the heater core. Good luck!

[@adrianmendez3451]

@@michaelyoucanfixthat ended up being a 3k job, heater core alone at Christian Brothers Automotive (colorado) charged close to 2k for the placement. I still had coverage from a warranty, so I ended up not paying anything but the deductible, I just found it crazy hoe much its involved, including evacuating the ac unit. This is the best most informative video though for sure. Thank you

[@michaelyoucanfixthat]

@@adrianmendez3451 That is crazy! I spend like $120 for the heater core and antifreeze. But it toke me about 6 or 7 hour to do that heater core by myself but that a lot better than $3,000. Thanks for share that info. That might help a lot of people decide if they want to do this job their self or not.

In the middle of changing mine right now. Had to take a break bc I couldn’t get to the nut behind the intake. Dropped my socket and can’t find it and about to flip out. Thanks for the tip on drilling the hole. When my blood pressure goes down, I’ll try that. It may keep my from burning the mother down right here in my yard.

[@michaelyoucanfixthat]

Sorry for the delay. I'm just now seeing the comment. I removed that cover all together. It will save you a lot of headache in the future. Just cut it out the way with a dremel tool or something to get it out your way for ever. You will be glad you did.

Thank you so much for your video ill let you know !!

[@michaelyoucanfixthat]

You can do it just take your time and don't get frustrated that things are going slow. The only thing you have to worry about is that you have to unhook your AC condenser which will release your AC freon. I did not show that part. Good luck!

@@FKNSENDIT Damn that sucks!

[@dakotabradshaw6883]

Hey bro. Quick question. Trying to diagnose my problem, I went ahead and watched your video to get an idea on what I’m about to dive in if it ends up being the heater core. But, I have an 07 Tahoe LT 5.3. The heat isn’t the hottest, today it was around 32 degrees. I had the heat on 80 and it didn’t seem to be as “warm” as it should be lol.

[@michaelyoucanfixthat]

I sorry it took so long for the reply. Be it sound like you have problems with your thermostat. I bet your thermostat is not opening all the way and not letting the hot water circulate through your heater core. If you had a bad heater core you would 1. Have antifreeze in your passenger seat floor. 2. Your windows would be fogging up when you turn on your heat. 3. You would have a load smell of antifreeze coming out of your air vents. If you don’t have one of the 3. You just a have a bad thermostat.

[@dakotabradshaw6883]

@@michaelyoucanfixthat that’s also what I was thinking. My windows do fog up with the heat on. Not awfully bad tho. Not coolant in the floorboard no antifreeze smell either. Thanks for the quick reply brother! And also this video is very helpful! If I was to have to replace it.

[@michaelyoucanfixthat]

[@rickdouglas8286]

I have a 99, had it 20 yrs, didn’t have heat for couple years, took to dealership, they wanted $800 to fix, ended up being clogged heater core, I took core hoses off and back flushed both sides of core, gunk came out, reattached, had hot heat, repeat this every couple years

[@Lady-Carmakazi]

@@rickdouglas8286 Yes good info. We did this & now have a little bit of heat but I can still smell antifreeze. At least we can probably make it through the winter until it warms up enough to be outside working on it ourselves. We tried to run hot water through it then used the water hose for more pressure, it did help. I think ours will need replaced very soon. Idk why chevy doesn't put an access though the glove box area so people wouldn't have to pull the entire dash away. Looks like a nightmare to deal with..

[@bigdurr9382]

Do you think I can get to the actuator to move it by hand My 2014 GMC Yukon is stuck on cold and not shifting to let the heat blow

[@michaelyoucanfixthat]

You should be able to get to the ones on the driver’s side of the truck. But on the passenger side will be more difficult and if you get to them. You can not just move them by hand. You will have to take the screws out of them then move the AC doors by hands or if you know someone with a good enough Scan tool. The scan tool have a function that move the actuators through the tool but if they are stuck maybe you can hit on it to get it to move. So but actuators are hard to deal with. They ether work or you replace them to make them work.

Is there more than 6 bolts inside the engine bay to remove the housing? We took 6 bolts out but the housing won’t budge

Did you remove the AC condenser? You have to remove that also or it will not move. I think it’s only 6 bolts.

[@adamfleig6508]

Thank you for the reply. We found there are 10 bolts in total. We realized we had to remove the ac condenser because there is bolt directly behind it and one below it. This video was very helpful.

[@7188010890]

Question why did you have to change the heater core in the first place I’m having a problem in my truck I’m not getting any heat but I change the radio and heater controls for a lcd screen that controls it all I’m thing that’s my problem I’m going to try to connect the ok’d heater and a/c controls back to see if the heat comes up if not I guess I will be going thru this frustrating problem

[@michaelyoucanfixthat]

You can have two thing wrong. Yes you heater core can be blocked. You can remove the two hoses going to your heater core and get the water hose and try to run water through the heater core to see if it comes out of the other side. or you can have a thermostat that is bad and will not let the hot antifreeze circulate through the engine to get to your heater core. You would know if that is the case because your engine maybe over heating. Most bad heater cores leak inside the truck or your windows fog up real bad. Or you smell antifreeze coming out of the air vents. For mine it was the windows fogging up. I hope that helps.

I wish you had a video on how to change heater core in a 2000 Suburban.....anyone know if it's drastically different from this one?

[@michaelyoucanfixthat]

Christy Buster I have a 2000 suburban. Is almost the same. I have did the heater core on that to many years ago. But if easier. If you can get the dash out about a foot. You can pull that heater core out from the top behind the dashboard. I was not making videos bad when I did that heater core. Just try it. Just think how you can get the dashboard out far enough to get behind it.

[@baynes1baynes557]

How did you know it was heater core was it leaking on the inside or outside

[@michaelyoucanfixthat]

There is 3 ways you know your heater cord is bad. 1) if you smell radiator coolant coming out of your air vents. 2) If you see water that smell like coolant on the passenger side floor. 3) If your windshield is getting fogged up as you drive and it does it every time. Most likely your heater cord is bad or going bad. I hope that helps.

[@jamesfaucett466]

The quick disconnect on the 2007 is better than the 2006. The term disconnect is a misnomer. I wish I had seen your video before I started to change my heater hoses on my 2008 silverado. I wouldn't have attempted it.

[@michaelyoucanfixthat]

Lamu Taafua Lamu Taafua It was leaking and it would fog up my front windshield. And I could smell a loud smell of antifreeze. And no I didn’t flush it because it was leaking. So, I knew the problem.

[@michaelyoucanfixthat]

Lamu Taafua mine was leaking inside the vehicle on the passenger side floor. When I removed the core. It had a rusted out spot on the core. But you will know if you smell antifreeze inside the vehicle most likely it’s your heater core. Especially if it’s coming out your vents.

Then there is one holding the air conditioning condenser strap to the fire wall. It may be one more around that area. Then it’s one or two behind the battery. Then if you have the hoses disconnected it should come out. There is nothing else holding it. Let me know if that works.
