Thank you so very much for posting this video. For three years, I went without heat in my 2000 Chevy Blazer, mainly because a major chain store mechanic told me that my heating problem was related to my blend doors, a costly repair of 800.+ dollars that I could not afford. I watched your video and located a back street certified mechanic who properly diagnosed the problem and viola, my vehicle has heat. As it turned out, there was nothing wrong with my blend doors. All my vehicle needed was a thermostat. I am a woman with limited mechanic skills, but your video gave me the confidence that I needed and saved me several hundred of dollars. Thank you! Thank you! Your friend in Pennsylvania. Keep posting, please.

Simple yet detailed video. No unnecessary details/statistics.

[@3DjPsycho]

Thanks man. Right length video, can clearly see what you're doing, no obnoxious editing, and no bullshitting around

[@lightwavemikala]

Keep the 2000 Blazer vids coming. They are really helpful to me and my creaky old girl!

[@ExposeZilla]

Awesome video. Well explained..There aren't too many of these bad boys on the road these days. My 2000 Blazer becomes an antique in July of 2025. Only 155k miles and she's still running like a champion. I hope to have it for another 25 years!

[@jessemendoza4792]

I really appreciate how you describe the size of the sockets and tools you need. It helped me avoid stripping bolts. I am not a mechanic by no means but with your video I knocked it out.

[@ShortStorytime]

This helps so much, Mark. My Blazer has been starting to run hotter than it should and this five dollar fix will stop thousands of dollars in damage later on. Again, thank you.

[@Mommabosss]

Thanks 👍 I appreciate this video. I am a woman who will be saving $300 with something so simple. You explained this so well

[@TheFrodiggs]

Just wanted to say like others, your level of detail, tips and being to the point gives us the confidence to do it ourselves. You make it look easy. Replying to all posts is a big plus. Thanks for taking the time. ('00 blazer, new radiator, runs hot fast, heat fades quickly and have seen water slow drip from the exhaust. Starting with therm replace first and coolant check)

[@God_is_Justice]

this is first time I see a youtube video posted by a mechanic who's English I actually enjoy listening to. thank you.

[@God_is_Justice]

LOL you bet

[@everydayguy1983]

I'm actually needing to do this for my work video this coming week. Thank you for a good camera angle and showing us what you're doing while explaining small details too. I am fully confident I can do this now, i am a visual learner and you helped me out alot. You have definitely earned a like, a subscription, and I'll be sharing this too.

[@ClassifiedsEarth]

Great video, 205,000 miles and my 2002 S10 is still running nice

[@clrkkent]

Hey mark I have a 2001 blazer and your vids have helped out tremendously. Keep up the great work on the tutorials and vids.

[@michaelkorrek7856]

Best ive seen and just found him by mistake

[@mrdrh99]

Holy crap man.... I've been having overheating issues off and on for a couple of years on my 99 Blazer. I already had the coolant flushed once and was about to spend another $100 at jiffy lube then I found your video..... Bingo! Fixed it! Thanks so much man!

[@randylee1047]

Doing one later today for my brother. Ive slowly became the family mechanic. Awesome video. Not to long. Informative on the coolant spillage problem. Thanks man!

[@HiddenRamza]

Great video buddy, Changing the water pump today and said why not the thermostat too while i am at it. Came here to look for location since this is my first chevy. watch a couple of vids but yours really was the best. Thank you for taking the time to make the video

[@torsoboi1132]

One of the better videos on the subject. Thank you so much for posting!

[@TheVolvo2103]

I watched several vids about this vid and yours was the very best...now I'm going out and change that booger

[@ErinFlandersakaBigMama]

Super Helpful. I am changing my thermostat today, and did't even know where it was located on my GMC Jimmy, so this helped me out a lot because it is the same set up. Thanks for posting. :-)

[@dsfcann]

If only youtube had a video this clear for every fix on my Sonoma ... Thanks!

[@greggeist369]

Hey thanks for your video !! I just finished changing my S-10 thermostat. The step by step video helped me alot. Had to buy a used 13 mm deep well at a a salvage store for $2.00 and the thermostat . Job well done .

[@InfiniteRespecto]

Thanks, it's about to get down into the thirties and my family and I needed this.

[@RealmsofPixelation]

Awesome video. Now I know exactly what to do. Thought this was going to be a pain but after seeing this it's obviously not that difficult to do yourself. Thanks for sharing and for saving me money!

[@billowens374]

Very helpful. I was checking KZbin to see if I could tackle this job myself on my Sonoma, and believe I can after seeing this video. Thanks!

[@Jonnydeerhunter]

I knew there was a simpler way of doing this. Thanks for sharing.

[@Justaname-00]

Thank you so much! Very informational and simplistic. The thermostat I purchased did not have a new gasket so I use the old one which was in decent shape

[@jennifersylvia2883]

Hi Mark, I very much appreciate you sharing this video, a body shop was trying to charge me $275 to change the thermostat! Probably because they thought a girl couldn't change it herself, thanks again!

[@jennifersylvia2883]

***** Yes it is, I do have a question. My thermostat seems to be stuck in place. I tried a screwdriver to try to lever it our but it is in there pretty tight. Any suggestions? Thanks again!

[@jennifersylvia2883]

jennifer sylvia Never-mind I pried it off :)

[@BartlettDaveJr]

Simple straight forward video. Thank you. Subbed, make more!

[@09thaboy]

Great video dude, explain everything well!!!

[@CNel-9999]

Very good video...step by step...right to the point...you can see what you're doing too...you don't over complicate the process.... Thx.

[@09thaboy]

Thanks for this video dude, will be changing out my thermostat in the morning!!! Thanks 🙏🏿

[@jamesjacobs592]

Great video sir!!! Very informative and simple!

[@jparsenault3911]

Thanks for the video very helpfull I feel better that I can do this myself now that I saw your easy to follow video and not get hosed for labour charges. Keep up the good work and videos

[@nickdonner6330]

Replaced one 2 years ago on mine having to do it once again but I came back for a refresher. Hopefully it goes better than last time when my bolt snapped off in the manifold!

[@ASMR-soothingsounds]

Thanks for the instructional video. I thought you did a great job explaining and demonstrating the steps.

[@leroytyrebyter5089]

Thank you for this instructional video... Especially for the tips...

[@James-lp5]

Green coolant instead of dex-cool? Oooohhhh I see, you like your seals to not go away! lol

[@Jonnydeerhunter]

Oh so you like chunks that clog up your Radiator and Heater core, Oh I see. That was a problem when they first came out with Dex-Cool that was quickly fixed. I've had over a dozen GM's and the only one I had issues with was a 2001 Silverado that someone put Green coolant into. You can't flush all the dexcool out and it causes a brown gum that causes clogs.

[@boofmastacam1260]

Great video and explanation! Thanks for sharing

[@kenshields7849]

great video... excellent job of describing what was actually taking place...

[@DudiScirocco]

thank you for this video :-) greetings from Poland / Europe :-)

[@ESPNsPeacockbassProfessor]

Hi Mark! On my s-10 the temp gauge climbs up,the check gauges light comes on,then the temp quickly drops back down to norm. I also found some particles like crud after removing the radiator cap any tips..

[@thoney59]

You just saved me lots of money and what details Great Job Make youtube look good Thanks so much

[@brandonpatterson4360]

Very well done video I like how you explain every step makes it fool proof. Is this the same procedure on a 2001 blazer?

[@dustin3700]

No. Location changed in 01 to the front lower passenger side of engine.

[@ShellaAlmazan]

Thank you for this. I feel after my radiator overheated when they replaced that. They didn’t do or suggest the thermostat. Which in turn I’ve heard can affect my transmission fluids not properly heating as it should and can be “a” cause to why my Bravada wants to not shift properly when at median of temp gauge. So I wanna try this and see and go from there. Thanks great video 👌🏻and lotsa light. Other than another video I tried to watch that someone else made tho. 🤷🏻‍♀️🤦🏻‍♀️

[@hischyoudontneedtoknow2896]

Thank you much did the second water pump in 3 months on my 97 S10, got the thermostat cover off wasn't sure how to get it free.

[@bryanrandom6382]

Much better than the other video I watched Edit: was your engine temp gauge not working as well as your heat?

[@davehardy3954]

Great video..thanks..about how long did it take?

[@eddytorres2239]

Thank you for this video! It helped a lot!

[@friendlyfireagains2855]

Great simple video! Yes make more videos!

[@whosej20]

Very awesome video........i will be doing this in the next 20 minutes

[@pantherpoolkid2145]

Great video. Thank you.

[@andrewz5170]

At 1:12 that bracket your taking off is behind the other one on mine. And I can’t seem to take it off

[@TonysWayy]

Aswesone Video my Friend.. helped out alot 🙏🏾

[@LeviCoultify]

You're a lifesaver dude!

[@12345Flipside]

Hello. Good Video! But i get not open my two thermostate-housing bolts out... I have fear to break it on the aluminum motorblock. What should i do now?

[@Mike_The_Hog_A_Nator]

I never mess with anything but the 2 bolts holding the thermostat housing. No need to remove all that other stuff, just asking for issues. Those bolts will snap very easily also. The 4.3 is very well known for snapping the bolts but it will seal with just 1 bolt. Been running mine for years with just 1 bolt in it.

[@berkmanyt]

Nice job….good explanation !

[@n.h.moreno]

Thank you sir....!!! My truck been spilling all kinds of fluid. I may have found out why.. Thnkx

[@jamesmaggia6437]

excellent video my Man!

[@johndillon7585]

Hey mark just replaced it thank-you for the vid

[@mbnauman]

Awesome - gave me the courage to give it a try. I really appreciate you taking the time to do this. Now, how do I know if that was the culprit? Ride it until hot I suppose...

[@adelevanrooyen4345]

Great video, thank you for sharing. Just one question, what spray lubricant did you use to loosen bolts?

[@edrosa5079]

I have to ask my truck just started getting hot and i had to turn on the heater to keep it cool is the thermostat the issue

[@artwhitaker5731]

Nice video, very big help. well done.

[@KarlMcGyverHaze]

The burp valve/toggle interferes with my thermostat housing. The guy at O’Reilly Auto Parts looked at all the thermostat options, and they all have the toggle valve to the side and it won’t let the housing seal against the gasket. 2003 Blazer. Do you know what’s up with that? What can I do?

[@KayJay-lc3cv]

awesome! keep up the great work.....

[@snipersson1]

Great video I appreciate it man

[@WVMountaineerGamer]

very good video thank you so much sir

[@mikemcdonald5060]

Did you take some coolant out of the hole before you placed the new thermostat in? You did not mention it or show it, but it looked lower as you quickly dropped it in there. 😁

[@jonathanflores9930]

what is the hose that u were describing that goes in your cold intake what is it for?

[@michaelkorrek7856]

Great video

[@nogripes]

Thanks!

[@SRTMustangKiller]

Very informative, thank you. Now, clean that engine bay up a little, looks like you've had it stored in barn for a year.

[@BlackIcex1]

Thanks you were to the point and it helped

[@noeromero6124]

I have a chevy S10 03. Will be the same thing to change it?

[@computethisnow]

nice video, i have to do this on the ole plow truck!

[@computethisnow]

yes it is

[@WilliamsPreCalc]

Heater still only blowing Luke warm air after I changed the thermostat. Any suggestions?

[@JorgeHernandez-we1tl]

Hey boss i have a 2001 blazer and its overheating I replaced the the thermostat but it's still overheating antifreeze is leaking in my passenger carpets What could be the problem..

[@philmanwarren3666]

hey mark love your videos i have the same blazer i was wondering if you ever changed your wiper transition before and if you did if you did a video of it ?

[@philmanwarren3666]

yeah it still didn't work i still have no heat any more ideas

[@philmanwarren3666]

***** yeah they are warm to the touch the gauge reads 180 and climbing

[@baldy194859]

thank you Mark ! you were very thorough ! would you know what degree of thermostat a 99 blazer 4.3 takes ? thanks again !

[@Ballinspartan7899]

195°F is OE

[@michaelbarbosa5696]

great video, it helped me thank you.

[@zostedguy]

Thank you! Nicely done

[@kontrilareu9591]

What spray you use on bolts/ nuts?

[@demariomac5288]

Is this the same technique for a 98 S10?

[@moiusa]

"Hyper tech" sales pitch... WOW! I'LL BUY IT!! 😂😂

[@itszenjii8773]

Is it supposed to leak everywhere?

[@msherry1000]

When I tried to move the 10 mm nut the whole bolt comes out. What to do?

[@eddiekunert2719]

Cool vid, thanks man.

[@eddiekunert2719]

Got mine done in ten minutes Cuz of you bro. Runs great.

[@007458689]

For my book Chilton says Thermostat housing nuts 4cylinder 89 in-lbs Thermostat housing BOLTS 18 ft-lbs For years 1994 to 2005 s series pickup and suvs

[@jorgereyes7347]

thanks for such a helpful video Mark. Btw, did you use an old pair of fruit of the loom?

[@Kabekiky1805]

Hey men you dont use to put some glue on the edge of Thermostat?

[@jesse197981]

[@telysabest8773]

Themostat change was easy but something happened i didnt expect! My engine now revs without me touching the gas. Idk what went wrong

[@mowafab]

sweet Hendrix poster man

[@joseantoniomedina9652]

Muchas gracias, muy sencillo y fácil

[@Tracer9GTRider8]

Nice, thanks!

[@SarahLevan-b7q]

Thanks again.. my thermostat, water pump.. upper and lower control arms inner and outer tie rods . Ball joints and shocks all the way around.. why would I pay somebody when I can do it myself..

[@jethorse2]

I have to do this on a chevy s10 four wheel drive with ac, year 2000.. is this exactly how that would be ? the same everything ?? lol.. i dont want to screw this up but im doing it because i dont have the money to have it fixed, , at sixty, im not afraid to try it, my husband can't do this stuff anymore, but he can sit and scream !! if its exactly like this, i know i can do it.

[@ghostkilla931]

Really thats it? I live in florida. And it 100 daily. Do i need one in the car at all?

[@peterwillems2422]

Without the thermostat, there is no gasket to seal the upper and lower parts of the housing

[@traviezo766]

It be the same in my 2000 chevy s10 4x4?

[@traviezo766]

Mark Jenkins thank you 🙏 so much my brother!!
