Hey man just wanted to say thanks for taking the time to make this video. My son's truck needed this repair and I was low on funds and time. The video was so perfect I not only handled the repair but was able to get out of the Texas heat(112 heat index yesterday) faster. Thank you brother, I want you to know this 20 min thing you did 4 years ago is still helping people tremendously. Thank you for sharing the knowledge and may God bless you sir.
Your very welcome!
Agreed! Thank you
Nice job, this is exactly what makes UA-cam great. People helping other people out. Sure I could fumble through this job figuring it out as I go but why not watch someone else figure out the hard parts and instruct you through it! Thanks man.
thanks for watching and commenting!
I notched out my fan shroud in a parking lot with a sheet wall knife for anybody unable to get to a sawzall. Putting that there was a GREAT TIP. Thank you
6 foot of snow in the background and short sleeves!!!!! Lol you sir are the man. Thanks for the video! Great job!!
Lol, gotta be hardy to live up here in the sticks. Thanks for watching and commenting!
Forgot your ring buddy, have all 10 would suck to only have 9 cause it wasn't thought of. Awesome vidja
Having no clue how to replace my water pump, Your video was straight forward, which was perfect for me. Replaying this several times, I was able to notch out shroud, replace pump and assemble back in 2 hours, 10 mins. You saved my ass and over $290 in labor. Thank you Sir!
Glad it was helpful, thanks for watching and commenting!
Thanks a ton, I went from $350-700 dollar quotes to just ordering the part online and following this video step by step. Cost me a total of $45.
Glad it saved you some $$$, thanks for watching and commenting!
Your wife did a great job holding
The camera nice detailed video
Thanks, I told her you said she did a good job. Thanks for watching and commenting!
Excellent, straight forward video. As a single mother in nursing school, you just saved me so much money. SO grateful people make these kinds of videos. Thanks Steve (and Steve's wife the videographer !)
Thank you thank you. You saved me hundreds of dollars. I think I got a quote to replace it for $800. Needless to say I went with the ladder...DIY. Pain in the butt but It was worth it. 🍻
No problem, glad it was helpful and saved you some $$$. Thank you for watching and commenting!
Thank you so much for the video, I don't have to do mine yet but when I do I'm watching this again, you are very appreciated
Sir you a damn Genius I wrestled with my fan shroud for 20 minutes trying to get it out to change the water pump after seeing your video I get to Sharon out of the Envoy I went out and cut mine
My trailblazer broke down on the way to work. Limped it to my nearest auto parts store and changed it right in the parking lot. My belt was shredded and truck was heavily smoking haha . But you helped…. A TON.
Thank you for the very informative lesson. I did exactly what you told me & how to cut the U shape cutout & trust me it definitely saved a lot of time. I had the job done within 45 minutes . I owe you a a few ice cold beers . THANKS !!!!!!
Completed the process today and got it done per you instructions. While the fan was out I took the liberty to replace the belt, new tensioner, pully and the top coolant hose. Thank you for the excellent video.
Great video. I've had 4 water pumps replaced since 04 and now its 2020. Still running strong with no major issues.
Most thorough video I have ever watched. Changed mine out just as easy...thanks the that cut trick. Thank you so much for posting. Was quoted 500$. Did mine for 65$
I'm glad to hear it saved you some $$$. Thank you for watching and commenting!
Much appreciated. Helping my brother do this next month. To the point with great tips and good angles. Thanks again
Just want to say thanks for this video! Well done. Dealership wanted $700 for this job. I replaced water pump $88 AC Delco, $25 belt, plus antifreeze. Thanks! I did notch the shroud to allow clearance past the radiator neck. Pulled both the shroud and clutch fan together straight out with no problem. THANKS!!
Wholy cow thats some serious dough! Glad to hear you were able to get it done yourself. Thanks for watching and commenting!
Just changed my water pump, couldn’t have done without this video. Thank you
Glad to hear it helped, thanks for watching and commenting!
Solid video, dude. As someone who has done this job to anyone watching and preparing to: Do not even consider trying to get that shroud out without cutting out the notch described here. Saves a ridiculous amount of time and frustration!
Thanks for this video brother and for taking the time to show us the right way to do the job !! I change it two years back and took about 3 hours , this time took me 45 mins
One of the best videos on the fan clutch replacement. Thanks heaps!
Thank you. You walked me through my first ever pump change after my one seized and shredded the belt and pissed coolant everywhere. I know nothing about cars, and I did it thanks to you.
That's awesome, glad to hear the video helped. Thanks for watching and commenting!
Bro how can I send you some beer money this video just made my life so much easier. My Trailblazer will finally pass inspection again after two years.
That's awesome! I'm glad to hear she will be a legal beagle once more.
Watched your video today and was able to knock it out just as you did. Never worked on a car before. Your tutorial made my experience painless. Thank you.
Glad it was able to help, thanks for watching and commenting!
Your video is correct. I did all you advised and it was much easier than the first time I changed the water pump. Thank you for this time saving hack.
Thanks Steve, this video was very helpful. I struggled to remove the fan nut until I stumbled onto an interesting solution.
I put a 13mm closed end wrench on one of the four pully bolts and spun the pulley counter clockwise and the wrench landed on top of the crankshaft pulley. Then when I tried to loosen the large fan nut, the 13mm wrench stopped the pully from turning because it was resting on the crankshaft pulley and at the same time keeping the pully bolt tight. This allowed the fan nut to come loose. I think I only stumbled on this option because I had already removed the belt and could see the crankshaft pulley. Thanks again for the video!
The water pump on my 06 TB EXT is about to go it’s very wobbly and making a horrible noise. This is one of the best vids I’ve found. Thanks for the help.
Great video . Prior to me watching , I was surely going to let the professional do it. Dealing with removing the radiator,,I DIDNT WANT TO DO. After seeing how you cut the cover , Bam! Too easy. I didn’t have that cutting tool you have. Instead , I drilled a hole on each side of the cover (upper radiator) then took for tin snips and cut. Great video . Thanks !!!
HUGE help! Great fix to an absurd problem!! Much appreciated! Will say simple but genius. Thank you!
Thanks for the "cut" tip. I have that shroud & fan ready to pull out but I couldn't force it past the radiator neck. I jumped onto this video and found your great solution.
Glad to hear it helped you out. Thanks for watching and commenting!
Good video, thanks for posting. Shroud cutout hack looks like a real time saver. I will definitely go this route.
Thank you! My Chilton's showed about the same process. Video helps 100% . Makes me wish it was my old '70 350ci now that was Simple!!
Just used your video to replace my water pump so thanks! I cut out the little piece as well! Quick and easy
I did my cut out too. My water pump started to do the weep hole drip. Ordered the pump and fan clutch kit. It's coming in a few day. I drained it from the bottom hose and will torque the pump to 1st 35 in. lbs then final torque of 89 in. lbs. Good video.
Good job. My partner and I now just replace waterpump without removing shroud. It is not to bad. Got it down to 1 hr.
Wow! great video, thanks for the very clear step by step instructions.
Thank You So Much. My brother just got finished with it. The transmission lines that snap into the shroud were the biggest pain.
Well done explain to everything slowly and perfectly thanks I have some friends that said it was going to cost over $4,000 so I will give them your video save them a lot of money they're just getting married
Excellent video! Well done, thorough and user friendly. Thank you for your effort and time
Awesome video. thank you. I'm about to tackle my 02 Envoy water pump.
Thanks for the video. The info on the shroud for the radiator was really helpful.
I replaced the water pump yesterday on my 2005 Chevy Trail Blazer. I just tapped the big nut of the fan clutch and used a long screwdriver wedged between the pump pulley screws to loosen it. Thanks.
Thanks so much. One of the easiest way to get through.
Thank you for taking the time to do this
Super helpful video. Saved me hundreds of dollars! I really appreciate the level of detail. Made the job very easy. Btw, the bolts for attaching the clutch to the fan get 15-20ftlbs. At least on mine.
The notch is a good idea. I was told to cut the shroud in half but this is way better thanks
Thank you for the video Steve, really simplified the repair.
Thank you, Steve. That was a really good video start to finish. I like the shroud cut-out tip. Good instruction/explanation as you went.
I'm glad to hear it helped, that cut is a major time saver, not sure why they didn't just incorporate a gap in the shroud from the factory. Thanks for watching and commenting!
My water pump blew out when I was on the high way and threw and shredded my belt on me. I figured it was the water pump because the massive hole in the front of it. Thanks for a step by step on replacing it.
Thank you for your video, just did my girlfriends truck with no hassle. Good video!
Very nice video... Nice job of video and narration.. Great tip on the shroud cut as well.. Cheers..
Omg thank you so much brother just finished replacing everything with your guide 🤜🤛
Thank you very much for the video helped alot got the water pump done less than 3 hrs 👍😁
An old butter knife and a propane torch made the cut perfectly.
This 2 year old video helps still man. Thank you!
NOTE: On the 2002 Envoy, if you've never replaced the fan shroud, there are two rubber bumpers on either side that are held in by hooks which will take a bit of wrestling to dislodge from the shroud.
How did you get them off,and did you hook the back up?
@@mjnesscatt I fought 'em off by muscling them about using a pair of pliers. They're rubber so they will give as you guide them over the plastic hooks. I made a video showing how it came back together for ya: ua-cam.com/video/83_CYrb07XM/v-deo.html
Great instructional video, simple and straight forward.
Thanks for watching and commenting!

Your welcome!
THANK YOU FOR THIS VIDEO! wish I would’ve seen it a year ago when my water pump and radiator pooped out on me, would’ve saved me from being miss spaghetti arms and many hours lol. This job only took me about an hour and a half and saved me $450+! Thank you again :)
Your welcome, I've seen some serious repair quotes for this job. Thanks for watching and commenting!
Supper good video with time saving tips. All done by a real man out doors in the winter.
Thanks for watching and commenting! Things always seem to break in the winter.
Just what I wanted. Stright forward to the point. Thank you
Glad you found it helpful, thank you for watching and commenting!
144k people have been helped by this video. Nice
Thanks a lot brother......saved this recreational home garage mechanic a lot of time....
your welcome, glad to hear it helped, thanks for watching and commenting!
Thank you for the step by step tutorial now I can do it myself and save some money 👍
Your welcome, let me know if you run into trouble, Thanks for watching and commenting!
Steve,
Thank you so much! I have an AC compressor clutch and or coil to replace on my Envoy with the 4.2. With the fan and shroud out of the way, I should be able to do it with the compressor on the motor.... Gonna save me time, money, and busted knuckles. You Rock!
Glad to hear it helped you out. Thanks for watching and commenting!
I love this video so much. Thank you so much. Not all heroes wear capes. Wherever you are I hope you're doing amazing & I owe you a beer for helping me with this lol
🛠🏆👍 Your video is the best one out there for this job. I especially like your shroud notch tip at the 7:00 mark. Yes, GM should have allowed for that when the shroud was made! Your solution is brilliant and a real time-saver. I also like that your explanation was clear and straight forward with no annoying hip-hop/rap/thrash metal “music” blasting away in the background. Only amateurs include music like that. Like the Ford 4.6 water pump, the TrailBlazer/Envoy is one of the easiest ones to do- although my Crown Victoria was even easier. 😆 Thank you for taking time to make this excellent walk-through tutorial.
Appreciate the kind words. Thank you for watching and commenting!
Brilliantly done. Thanks!
Thanks Steve! Tom from Ohio. 2005 Envoy. Not an issue yet , just planning ahead so I'm ready to go.... if/when it does fail
Awesome video THANK YOU !!!! so much .The best video .Im just learning to work on these newer cars .I feel more confident to do this job .I'm great at working on my 55 Chevy but these newer cars are confusing ,I guess its just getting with the program .Again thank you very much.
Best way to save money, do it yourself. Thank you for that advice, and saving time, by cutting the shroud..👍🏽
Thank you for your clear explanation 👍 you did a good job amigo 👏
Great video bro!!! You didnt miss a thing
Thanks sooooo much, great video! Extremely helpful
Your welcome, hope it helped you out, thanks for watching and commenting!
Great video, thanks for your help Sir !
This video was very good. Keep up the good work
Thank you for watching and commenting! I hope it helped!
Thanks for walking me thru the process as we speak lol 👌
outstanding tutorial and above excellent advice on cutting the shroud! thanyou so much
thanks for watching and commenting!
Excelente, muy buen trabajo paso a pasito muy despacito, esplicado detalladamente y con las herramientas nesesariss, nada es difícil, gracias por compartir, buen día.
Very helpful thanks!
Thank you sir. Great video!
Thanks for the video, I did mine too but I kept the little piece I cut out of the shroud and hot glued it back in when I was done, just to keep all that air flowing like it did before I cut it out
@Steve Young GREAT REFERENCE! I did this job yesterday and the Thermostat and ECT Sensor and this helped a lot! My tip to all is: if everything goes smooth except getting those damn Trans cooling lines back into their slots- you can take a Dremel tool and trim them down and it will fall into place like butter PLUS the cooling lines will still sit where they belong..they just wont "snap" into place but will have support. Once again EXCELLENT reference for doing this job correctly! Also, I believe the giant clutch nut wrench is size 1 7/16(Item #25193) ordered from Ace hardware.
Great Job man!! ill be doing this repair this weekend and I'm completely confident I can do this. When you made mention of the cut out on the fan shroud I was thinking "fucking Right!" Thank you for this video ! Again great video ! to the point not too much talking and bullshit and you obviously know your stuff!!
This video is great, but you dont have to cut the shroud - if you undo the fan motor bolts push back toward radiator then shroud eill just slide up past extruded pipe housing.
Thanks for the video helped me so much thank you man god bless you
Your very welcome, thank you for watching and commenting!
Thanks! Followed video and great video.
Your very welcome, glad it helped! Appreciate the tip too!
Just did this a few days ago. The notch is a great idea. Of course I'm a few days late on that one. Not only will it save time but might save your radiator. There is really no way to get the shroud out without putting alot of stress on the water neck of the radiator plus gouging the fins with the bottom of the shroud.
Great video. Excellent positioning and descriptions. Awesome tool description too.
I caught the 10mm water pump bolt tightening mistake but that was the only one.
I usually dont need a torque wrench anyways. 89 ft ponds is way too much. haha
Id say 25 ft pounds is good. Thank you my good man.
Thanks!, yeah, 89 inch lbs was what it should be
Good job sir, and good job wifey for filming it correctly. 👍👍😁
Thanks for watching and commenting!
Video really helped me out. Keep posting when you get an automotive opportunity lmao.
The best ,the best video,hey guys doing videos how to repair cars or trucks this is the way to do videos “I called waste of time videos “the others and gracias Señor you did it GREAT VIDEO
Thanks for the video help me out 💯👍👍👍
Glad to hear it helped, thanks for watching and commenting!
Great Job! 👍
Thanks for watching and commenting!
thanks for vid helped big!!
Your welcome, thanks for watching and commenting! Glad it helped.
Agreed on cutting the notch. Dont forget to mention the un clipping of Tran cooling lines
GREAT, video, thank you!
BUT it’s 35 INCH pounds and then 89 INCH pounds for those small 10mm head water pump bolts to block
You’ll break or strip them if you use FOOT pounds
So wish I saw that before I did it... On a positive note, I haven't had any leaks with just 4 bolts on my pump.
If you're worried about the hole in your shroud affecting cooling performance, Gorilla Tape works very well to patch it up when you're done, and it blends in with your shroud so it doesn't look too bad!
Bro thanks!!!!
