Thank you so much for the video. Been helping my girlfriend get hers running after sitting for 8 plus years. Rebuilt throttle body, changed clutch master cylinder and slave cylinder. Then, front brakes locked up. Put on new brake calipers and new rubber hose on one side, finally she got to drive it to gas station. While waiting on her to get gas, heater core started leaking in floor board, so this will be our next project. Thanks again.

I've been watching a bunch of videos about this and you are the only guy that actually explains the right way to do it, instead of just showing pics of some rusty part and the whole dashboard taken apart.

9:09--"Oh yeah, pieces breaking off, that's good!" The pieces he referred to are visible very briefly at 9:09 in the video where you can see the third screw hole on the top right that he broke. In order to remove this screw correctly, you HAVE to unbolt the dash to get a little room. It IS do-able. If this screw is intact in your dash, you will not be able to remove the plastic piece from the bottom without loosening the dash, most of the dash. This sixth screw is why all the other videos are actually correct when they indicate the dash must be loosened.

I agree, this was a really helpful video. I watched it twice and in less than an hour had the swap done. Thank you!!

Thanks for helping a old man understanding how to,great video.

I love how u edit your videos, they’re so funny yet informative

Much appreciated man. Replacing the one in my 91 s10

OMG thank you for this video! I thought I was screwed but this helped me realize how simple it actually is.

YES GOOD VIDEO. LIKE THE MECHANICS ATTITUDE AND MUSIC AND DECENT LIGHTING EVEN AN ARROW TO IDENTIFY THE RIGHT BOLT.

Dude loved the video. Thanks alot. Both insightful and entertaining. 😎🤘

Keep the videos coming bro! I'm on the edge of my seat to see the final product!

Thanks for the video. I just found a puddle of coolant in the passenger footwell. SO I need to do this and had no idea, thanks!

Nice work man! Very helpful and to the point.

Thank you very much. I have a book and I can turn a wrench ,but sometimes it's easier to see it done. It was very helpful . Thank u

i lost it when you popped off the first hose. cant wait for you to get your truck done keep it up

Very helpful. Short and to the point. Thanks.

Great video ! I have an 1988 S10 Blazer with 418,000 miles...I love working on my truck and now I am exited to do the heater core now that I saw this video !

Dude this helped me so much! Thanks man!!

Bro the step by step location of bolts size of sockets dude 100% love this super confidence inspiring.

This is the exact video i was looking for. Super helpful. Will def sub and follow.

Great video! My 2002 just started leaking; this video was very helpful.

This video helped me out so much . Thank you

Thanks for the video friend..now maybe i can fix my old but nice 91 S-10..was dreading the job but now think i can - it's been a great truck, thanks again :)

You are the Man!!! I had to by-pass my heater core about 2 months ago, I couldn't drive my 92 S10 5 miles & there would be a puddle of antifreeze in the floorboard so I by-passed the heater core. Now I have a long day tomorrow, my heater core & evaporator core came in today so I have to replace both because of leaks. Thank you for the easy part, but there is no easy way to replace the evap-core, plus it is suppose to be in the 90s today. Guess I'll start early in the morn before it gets to hot. Good luck to all & let's keep the S10 nation rolling 1st or 2nd gen. Personally I prefer the square bodies, but to each their own. Stay safe, Peace, Love, & Happiness to All.

Nice video doing this job on my 91 s15 ...im watching walking dead and it was a real drag watching you get bit carl you were my favorite character

Thank you for the video i was working on my chevy and stop when i coulnt take the plastic cover of the heater core but your video help me a lot thank you very much May God Bless You

Thank you very much. Very usefull!!! I tought it would be more complicated.

Nice. Simple and easy to follow. Thanks.

Thank you, just picked up a 93, noticed coolant inside leaking. New I was gonna need to change this. Looks like an easy day!

Great video! Very helpful and very detailed

Thanks, helpful for a start to change mine. Losing some fluids and seems the the core is leaking as I smell the fluids with heater on

thanks man this helped a lot 👍🤟

Thanks man! Really helpful video.

Thank you! This was a lifesaver for my '88

thanks for the solid video man bout to pull mine

Chill video bro. Doing a swap fore a new core on my 92 s10 blazer. Thanks for simple easy way

The easiest heater core I have ever done was a 1971 Ford Galaxie. It is at the back of the engine compartment on the very top. Pull the two hoses off, which is real easy, pull 8 or 10 little screws and pull the metal cover off the top, and pull the heater core out of the box..I done my 88 S10 several years ago and it is no picnic.I pulled the end of the dash loose and back just a bit to keep from breaking things, like you did.

Very helpful sir. Thank you very much!

Keep it up man love the videos

excellent video now if I can get my 73 yo body down in there. If I hadn't watched your video I would not have tried it. I grew up with 1950-60 cars that were easy to work on. you rock

Thanks that helped alot I have to replace the heater core in my 89 S10 pickup

Thank you my man. I’m about to change mine out right now. =)

You saved me $561 that the mechanic wanted to charge me so thanks! I live in Montana and winters coming and my heater core just quit on me.

Very helpful. Thanks 2 u I did it myself.

That was helpful. Thank you.

Very helpful thanks.

This is perfect, my 86's heater core just shit itself and now I know how to fix it.

GREAT VID super easy , just replaced the heater core in my 91 s10

Had to do this in my 92 civic and had to take the whole dash out so seing this made me feel better 👍

Thanks man. The other videos all made it seem like a night mare

Great video man! Hope you do well in life.

Bravo on the POV camera views, amazing thanks!

Where did you get the clear side marker lights

Yeah man this helps a lot about to do my 1985 2.8 v6 it’s getting cold out!🥶🥶

Good vid man, im about to start doing mine right now.

Going to do this on my 84 jimmy this morning. Looks like fun.

thank you. very well done and helpful..

Doing one today. We bought a clunker and saw that the water lines had been looped. I couldn't find the nipples on the firewall. Thanks! Wobble suggestion... Use a flat blade screwdriver stuck in the back of the socket..wide enough to catch opposite corners of the drive (about 1/4 wide?) it will flop enough to go around corners and still torque. Use tape to keep from losing the socket.

Thanks for the assistance. 82 S-10 heater core fix. :D

Working on my 82 helpful video still a pain in the butt. Thnx

Will this work on a 89 S10 Blazer I was told I would have to take the whole entire dash apart

Very well done.

Amazing video... saved me some money

Great job and thanks.

Thanks for video, I'll try have 93 GMC looking at the same job.

Your video help me a lot..thanks

Great tutorial good job

Thanks for the video

A job well done.

Hey roman are you still offering to do renderings of peoples trucks?

I actually lol’d at the gta wasted thing! Now I’m a loyal subscriber

Wish me luck, I'm getting ready to do the heater core in my 1989 Chevy S10 PU

I just bought a 91 4cyl S10 and the previous owner had a leak and cut the heater hose lines. We cannot figure out where on the radiator and on the engine the heater hoses connect to. Do you have any way to explain where on the radiator and where on the engine the heater hoses connect to?

Great informative video now how do u flush it?

Great job!

Very helpful

This video, while it gave me the confidence to try this project. Even though I ended up completing it in the long run, it was way hard and very frustrating. Long story short I ended up ruining the first new part, had to cut the plastic on the enclosure to get the 2nd new part in and tore my hands up multiple times getting it back together. Even though it's back together the plastic didn't actually go back together because I would have had to take the front back off and cut it somewhere because the only way to get the straps back on was with the core maybe 3-5mm to the passenger side of how to should rest. this meant that part of the front piece rides on the core, preventing the plastic from seating all the way down near the door. I may yet take it apart one last time and cut the plastic more to see if I can get a better seal around the side. Very frustrating doing the job but your video is accurate as to pulling the old one out.

Thanks for video now how do you close heated vents I have a 1991 Chevy s10

Awesome, gotta change mine very soon... Easy fix, just another reason i probably will never get rid of/sale my old truck.

Good video; thanks. I think I am ready to go.

Perfect thanks

Was your heater core plugged up or was it leaking

Would this also work for 99 s10?

Very useful.

Nice thanks

Is this the same process for 1988 s10

Just rewatched the video got the year

Do you have to remove the whole dash?

Doing it this weekend

Thank you I just got a s10 an haveing this problem first video came up clicked it an shit it was the one thanks again granger Washington

I would have liked to see you put the new core in. It looked like you had a problem getting the shroud out causing a ding in the old core.

What is the background music? Listening to you was helpful and your info was perfect, but the music kept me in it.

making that look too easy buddy,. 👍👍👍 now i gonna do mine. ✌

Why replaced heater core? What are the signs? I’m loosing lots of coolant and I have wet floor passenger side

Great job. Please tell me, while driving my Chevy S 10 94 6 cylinders with my ac on, suddenly cold air stops coming and just comes "normal" air. Why? Can you help me?

What year was at S10

So where was the leak ? was it solderable ?

You are awesome

Good video I'm bout to help a friend do his
