The last bolt from the baffle where he reaches under the dash is more easily accessible if you take the ash tray out. There is an access hole in the back corner. Just reach under the dash and pull the wires/tube down. Then just use a long 1/4 inch drive extension with a 1/4 socket through the access hole. There are also two wiring harness connecters under the far right of the passenger side that can be unplugged to give you some extra play in the dash. Other than that mine went as expected.
This video is 10,000 times better than my Haynes manual . It said just take four screws out...... nothing about the dash. You are the bomb. Thank you sir.
I will soon join the ranks of those brave enough to attempt this job. My '95 S-10 is dumping coolant in the same spot. Update coming soon using your video.
Great job on this video. Especially showing the necessary screws to remove. I would have probably removed more than I needed to. Thank You for your help.
My brother just called me and ask would I replace his hc. I watch a video before yours and I told him no. After watching your video, I called him back and said I will look at his truck. Great video, the few people who hate it can't change their own oil.
Soooo helpful! Heater core went out as soon as we got freezing rain in KY. Truck has never been in a shop & i considered a shop doing it til I came across this! I needed all the little details!
Dude! I started on last Saturday at 11 am and of course it rained. I got it pulled out Sunday after it stopped pouring down. The new heater core is smaller than the one I pulled out and the pipes didn't match so I thought I had the wrong one. Come to find out it was the right core I just was hesitant to twist the pipes into position. Anyway, I got it reinstalled and all is well. I hope to never have to do this again but if you decide to save yourself some money and need some advice it's fresh in my memory so feel free to ask. You'll need a t-25 torx, Phillips screwdriver, 5/8, 10MM, 8MM, 7MM, and a 5.5MM socket. Total time about a whole freaking weekend as the dash DOES need to come out on a 95 sdime.
Good to see a video on this. I'm mechanically inclined but not on GM's lol. My Pops 93 Sonoma core up and took a dump all over the passenger side floor recently, so I've gotta do the same BS. Thanks for the video, I was dreading having to pull out the entire dash, you saved a huge headache for me.
I pretty much went step by step with this video. The exception for me was the two straps holding the core. Instead of attempting to remove the top screws (which you had to be a squirrel to access them), I just removed the lower two and bent the straps upward, careful not to kink them.
89 mustang had to remove gash twice because cheap hc tube broke putting on hose. 89 sunbird under dash. 92 explorer through glove box 99 deville under dash had to buy $34 self tighten clamp remover for hoses
I really needed to see how you got the core in. I got mine in but it does not seat all the way in. It goes far enough in to attach the hoses but then I can't screw the braces back on.
pretty good video, but may I offer constructive criticism. For me at least, it would help if you would start a little farther back and then focus in. tks.
hello, Im unsure if my heater core is leaking. in times past most core leaks are in the interior of the vehicle. This 1994 silverado 1500 is leaking from the drain hole at the bottom of the passenger cap.
I did that on my 1972 dodge D100. Its a job. I love your vidio because of have a s10. Pick up and an s 10 blazer that I need to do. Question is that why the AC DONT work becaue of the heater core?
I drop a 355 sbc into my 89 s15 and now i'm trying to figure out my heat it works, but it doesn't change settings like it suppose to due to that hose not being hooked up I think it was possibly removed during the install or before I got it

mackdaddy1911a1 glad it helped
Thank you, just changed one the core in my blazer with help from this video
Local guys wanted $500 to do this easy repair, again THANK YOU!!!!
Thanks for your video. Really helped my today. Start to finish less than 45 minutes.
that's great news!!

How can anybody dislike this video? SMH!! :)
Thanks a lot, great job.
I got a 97 GMC Sonoma, the mechanic wants $350+parts :(

Thank you 600 times. That's how much for shop to do... I'm nice in warm in my 92 Chevys10..
Going to try this on my 1991 S10 pickup. So praying it works.
That board you used to hold the dash is a great idea thanks.

I love this guy!
Wish I had seen this about a year ago. I broke the shroud and found another in a junk yard. Going to try to fix this myself and save about $220-$250.
Great video man. Looks pretty easy unlike others saying take it to a mechanic. Pssshhh. Thanks again

89 sunbird under dash.
92 explorer through glove box
99 deville under dash had to buy $34 self tighten clamp remover for hoses
I went to do this same job, and on my truck there are 6mm screws everywhere! Haha will have to have another go later.

Great help to a less than novice mechanic

+Reid Nunn thanx for the tip
Thumbs up. But check your focus. Great vid man
Good video brotha 👍👍

Thank you!
would I be able to jack the dashboard without having to worry about the passenger side airbags?
My baffle was dried out and it cracked in half when i removed it.
it’s a discontinued part.
maaaan
I did that on my 1972 dodge D100. Its a job. I love your vidio because of have a s10. Pick up and an s 10 blazer that I need to do. Question is that why the AC DONT work becaue of the heater core?
+Joseph Ryan the AC and heater are two different systems. they share some parts, but the heater core won't affect the AC
Do you know where the vacuum hose from the blend door actuator goes into the engine bay at i'm trying to find my vacuum hose so I can hook it up ?
maybe the vacuum reserve tank. It should be on the fender.. black tank.
I drop a 355 sbc into my 89 s15 and now i'm trying to figure out my heat it works, but it doesn't change settings like it suppose to due to that hose not being hooked up I think it was possibly removed during the install or before I got it
I'm asking if you had to drop the steering column down to do this replacement??
no. It's on the other side. ;-)
Thanks, I didn't think so but somebody else on you tube said they did, so I asked. Again THANK YOU!
Have a GREAT Holiday season !
This is not a 94 S10 pickup you're working on in this video
correct... this would be for Gen1 rev 2 dash in many GM S-10/Blazer variants from the late 80's to 1994 .
How similar would a 1995 Blazer be?
not much.. all different dash
