Just used this as a reference, worked great. Done heater cores in many vehicles and each one presents its own challenge but what he’s saying about those two bottom bolts is accurate. Just snap them off it ain’t worth it to go for them. The amount of bite those have on the box is minimal anyway. The hardest one to do is the first one he showed which is inside the box under the resistor. I see only way to get that one is with a 1/4 inch drive socket set and must have a swivel. If your hands are small (mine aren’t) you might be able to get with a short wrench but good luck. Only other pointers I can give to this is you have to pull the cluster out to gain enough clearance for the dash to swing back off the pedestals at the bottom. I didn’t and I broke my cluster glass (plastic though). Aside from that I did this job in 2 hours with a Milwaukee 1/4 electric ratchet and 1/4 inch socket set no bigge. Maybe add another half hour for draining coolant but I had looped mine over summer so I just had to reconnect my hoses. Fairly easy

I did mine today. I have long skinny arms and I took my left arm along the manifold and got to both those bottom hidden bolts no problem. I didn't break anything and didn't drill no holes in the box. I reinstalled all the bolts and it took about 3 hours. First time doing this type of job on a chevy. Did many chrysler products.

@@steveandrews1982 Sweet. Well if you have the means (skinny lol) then do it. I’m a big boy @270 lbs so wasn’t any way my arms were fitting back there. I do own both styles of these trucks with 2.2 and the 4.3 v6. I can see on the v6 there is definitely more room to work being the engine is skinnier around where the bottom of the box is, might be easier on that but the 4 banger has that obnoxiously large intake right in the way. Either way the job isn’t too bad considering other vehicles. I’ve put heater cores in an S10 now, multiple 97-03 F150s, couple in 3rd gen rams, one in a Grand Marquis and several in different 97-up Econoline vans. The Econoline would have to be the easiest of any vehicle I’ve ever done. With coolant drained, it’s literally a 30 minute job comes right out in the passenger floorboard with few screws removed. The F150 as I recall was probably the most involved of them all.

All bolts can be gotten with out removing fender well or tire. You got them from underneath woth 10mm 6 inch extension and electric/air ratchet. The hardest one is the one you get from top, you have to remove the evaporator cover. Funny enough I got all the bolt out and still ended up breaking the tab he said to go ahead and break anyways. Bit it is easy to get out, took me 10 minutes to get all bolts out for heater core.

The truck is amazing. I didn’t maintain the coolant and I allowed it to have rust inside the system. The repair takes a long time and I should have done a better job but it’s been a great truck especially with the heater fixed. If not for the heat inside the cab it’s for the defrosting of the windows that really matters

I have a 95 Blazer 2-door 4x4 that I've been driving for about 7 years now and let me tell you, there are so many engineering mistakes in this thing it isn't funny. Not necessarily fatal flaws but things that make it a bitch to work on. To start with, ordering parts is a pain. If I order online, I almost always get parts for a '94 S10 or '95 C-series truck. Like nobody has set their computers to know that after 94 there were no more full-size Blazers made, ever, and the S10 is no longer designated as an S10 unless it's a pickup. If I say Blazer, I don't mean Tahoe or Sierra. I love my truck and I'll keep it forever, but, as I go, I'll be "re-engineering" it just as you did here. A lot of the problem with mine is they packed essentially the same 4x4 drivetrain from the full-size trucks into a short wheelbase mini truck and there's no room for anything. They had to put a remote oil filter system on it because you cannot get your hand to the location it would normally be, on the bottom of the engine. The steering, exhaust, transfer case and front drive shaft completely close it off. I haven't had a heater in it for 3 years (only need it 2 or 3 weeks of the year in Florida) but I will be replacing the core soon. Thanks for the video.
