Your videos helped me replace the front end on my 01’ GMC Sierra 1500. Thank you. Now I’m on to the water pump.

[@1AAuto]

You can feel the hoses before and after the thermostat to see if it's opening and allowing the anti-freeze to flow through the system. If the thermostat is old, it wouldn't hurt to replace it to begin with. They're usually only a couple of dollars. Hope this helps you out.

[@chancafer]

KZbin is great, and it would be nothing without videos like this, thanks for uploading this, now off to the garage!

[@russglover9851]

Thank you very much for making this video! It saved me $350 replacing my 2002 Suburban water pump, thermostat, serpentine belt, and A/C belt.

[@ScottWConvid19]

I love how you guys fast forward through all the tedious tasks that consume a lot of time. Your videos are super helpful. THANX!

[@1AAuto]

Thank you for watching. Please let us know how the repair comes out! 1aauto.com 888-844-3393

[@jaimemiller440]

Great video!! I do agree with one of the other commentators that the Large Crescent Wrench & Hammer need to be added to the tools list. Other than that I was able to follow the instructions and with the exception of a coffee break, was able to finish the job in about 2 1/2 hours. I did have trouble getting the fan off as easily as you did. Thanks so much for your video.

[@brianharrison2357]

UPDATE: Thanks again guys on the video it was extremely helpful. The operation was a huge success thanks to your helpful tips. The only thing I had trouble with was getting the fan/clutch assembly off the old pump. It would slip so that I couldn't get any torque on the nut. I finally went to the store and found a "FAN CLUTCH SPANNER WRENCH". This tool saved the day ; it resembles a large flat open end wrench with two metal pins on the tips that went in to the respective holes on the pump pulley. This allowed me to get the necessary torque to remove the fan. Thanks again and I will be a regular user of of this site for both parts and repair advice! Sincerely, MickeyBro!

[@imderrickjed]

The videos you guys offer are great. Ive been working on and building cars for 20 years and you guys are the only ones I see offering all the information needed. We dont do everything the same, but I have not seen anything wrong with any of the videos you offer. Great job guys!

[@angelmacias8754]

good video I just did the same repair on my 2000 gmc sierra 4.8L saved some money by doing it myself thanks to this video why pay somebody when u can research the repair and do it yourself thanks alot for the step by step video!

[@1AAuto]

Thank you for watching. Glad we could be of help. Please let us know how the repair comes out! 1aauto.com 888-844-3393

[@MrAvalanche316]

This video is awesome!! I had a water pump problem and followed it step by step this evening to fix my 02 chevy avalanche. I let it run for about a half hour while I cleaned up my garage and not one single leak!! I'm thankful to finally have the dreaded low coolant light finally gone. Thanks for this great video.

[@1AAuto]

@MrAlnj06 I'm glad we could help. We carry many different kinds of water pumps for Chevy vehicles.

[@avguillen1]

Great instructional video! I just finish replacing the water pump, upper & lower hoses, thermostat, ac belt and the main belt on my 2004 silverado. I was a little leery on doing this work myself but after watching this video I felt confident enough to perform the job. All went well. Thank you very much. Great video's, keep up the great job..

[@tjdinfl]

Thank you for this video! I am not a mechanic (by trade) but am very mechanically inclined; I do all my own oil changes and most repairs. After seeing this video and all the steps made this so much easier! I normally would have saved this for the weekend but after watching, I knew I was going to knock this out this afternoon...2 1/2 hours...and I took my time because the truck was hot. Now, nothing to interfere with the gun show on Saturday! Thanks again.

[@warmothgmc]

Handy reference video I used to replace the water pump on my '97 GMC Sierra, but there were a a couple differences. #!, on the '97, no need to remove the tensioner pulley; but, the idler pulley did have to come off to get to the heater hoses. Removing the fan clutch was the biggest challenge. You MUST use penetrator to let it work into the threads to work it loose. I also used lock tight when I reinstalled the new water pump. A clutch bolt wrench is a must here. I used a 15" crescent.

[@cwinaz5862]

Thanks for the video. I was able to do replace the water pump myself. I used the clamp method to keep the fan belt from moving and a pipe wrench to remove the fan clutch. I had good leverage with the pipe wrench and the fan clutch loosened very easily.

[@sreilly]

Great video. I'll be replacing my water pump on my 2003 Silverado tomorrow. Thanks!!

[@mryellowcrown]

THANK YOU FOR THE TIP A FRIEND AT WRK TOLD ME TODAY TO CHECK THE 2 FANS ALSO .. I MAY HAVE TO GET ENGINE HOT ENOUGH I DID 10 MILES FROM WRK TO HOME IT 78 TODAY HERE IN AZ ! BUT FANS DID NOT KICK IN WHEN I CAME HOME . (WARNING FAN MAY GO ON ANYTIME) SO I'LL TRY AGAIN .. THANK YOU VERY MUCH . I WILL LET YOU GUYS KNOW HOW THE OUT COME GOES .. KEEP UP THE GOOD WRK GUYS..

[@robertovargas5340]

Highly recommend the videos these guys put out. Easy step by step instructions. If you are up for the challenge, you can not get it wrong with this video. Mechanic all my life and can speak from experience that the info these guys give you is precise and complete. I have not ordered parts from them but will be looking to give them a try next time I need to order parts. The videos, all I have to say is job well done 1A AUTO! Tampa Florida

[@1AAuto]

+Roberto Vargas Thank you for the great reply. We love to empower our customers by showing you how-to perform your own auto repairs while installing our high quality auto parts. Have a great day! 1aauto.com

[@SuperCyril2]

Great job Mike. Thanks for the video. Hey guys, this info is for anyone who's having their engine temp go above normal operating range after new pump install. This is happening due to the thermostat not letting coolant flow to the radiator. What I did to correct this was, first make sure engine is cool. Remove hose from top of water pump. Locate the overflow hose thats runs from the top of fill resevoir to the left side of the rad. Disconnect this hose from the rad. Go back to the hose you removed from the top of the water pump and hold the hose up so you can pour coolant in it to fill up the radiator until the coolant runs out of the hole where you disconnected the hose for the overflow on the radiator. Hook both hoses back up where they go and restart vehicle with the pressure cap off the refill resevoir add coolant as needed until proper level has been reached. Goodluck. Hope this little description helps you out. Cheers

[@blackfishblackfish]

Thank you. Replacing my water pump on my 2001 z71. 187K miles. Your video is just what I needed. Thank you, as money is tight right now, so I can't pay someone to do it, and I don't mind doing it myself, just need to be shown how.

[@231MasseyFerguson]

Love this video! I have an '04 Silverado 1500 LS, 2WD pickup with the 4.8L V8. The truck hasn't gave me a problem yet and it has alittle over 90K miles on it. After watching this video, I know i can change the water pump when it comes time. THANK YOU!

[@tiledave621]

Thanks! I did my water pump on my 04 Silverado last weekend. Thanks again

[@1AAuto]

[@1dorepus]

You did a great job in showing us how change a water pump on a 2002 GMC Yukon. It was so easy after watching your video. One thing I think you should put in the video is the Air Compresor belt under the waterpump.Since your are there you might as well change the belt.

[@scottbender4936]

Great video, it walked me right thru it. Just be sure your adjustable wrench is big enough when taking off the fan. My 10" wrench was too small, I had to use a pipe wrench.

[@CorruptedWorld100]

was going to pay to get this done but i never realized how simple it was this will be my project this weekend thanks guys!

[@1AAuto]

+CorruptedWorld100 A little know-how can go a long way. Please let us know how the repair comes out! 1aauto.com 888-844-3393

[@peterhorn9934]

Thanks for your video. This was my first auto repair, and you made it easy. You have a great price on the water pump, too.

[@rossettielectric]

Hello and greetings form Bethlehem PA. Just replaced the water pump on my 2004, 2500 HD Sliverado 4WD@ 150,853 miles. You could not have made it any easier. I would not call myself a diagnostic genius at all,, but once I know what the problem is, I can usually replace the part. The video was exact, and I followed it to the letter. I just subscribed to your channel, great job!

[@1AAuto]

Great little trick for getting all of the screws in the correct places.

[@brianharrison2357]

This is awesome! You didn't talk like anyone watching was a dummy! It (the video) helped me think of replacing my water pump was not such a daunting task. It looks like it will be easier than when I replaced the pump on my Lumina! Thanks I will fill you in on the final results of my install. You guys are a life saver I will definitely recommend and use you in the future! Sincerely, Mickey Bro!

[@1AAuto]

[@1AAuto]

@wavehog41 You may want to replace the thermostat and also try to relieve any air pockets that may be in the system. To do this (when the vehicle's cold) remove the radiator cap and start the truck. Turn the heat on full blast inside of the vehicle and monitor the level of the coolant inside of the radiator. It the level goes down top off the radiator with some fresh antifreeze. Hope this helps you out.

[@TexanMilitia]

Thanks for the great and detailed video! Much appreciated! 👍🏻 I replaced a water pump in a 01 Ram about 15 years ago and this video really showed me how much extra work I did just from lack of knowledge. My Sierra thanks you very much 😂

[@popeyeandy959]

Mostly a realistic video of the job. I like how you don't edit out things like dropping a bolt (which probably rolled to the exact center of the truck - as they always do). I say mostly because I've never heard you curse at a stuck bolt or a slipped wrench. LOL. Nice job on these videos

[@1AAuto]

You're welcome. Thanks for watching.

[@1AAuto]

@richcramify If you took the belt off you may want to put it back on, this will put some tension on the pulley so that you can break the bolts loose. Once you break them free you can take the belt back off and then continue removing the bolts.Hope this helps.

[@davidg9167]

This video help me to replace the water pump on my 1997 K1500 4.3. Not quite the same but close enough. One whack (or two) on the fan nut didn't do it for me. I kept at it for 5 minutes and grabbed the belt to help it stop moving but finally got it. The hardest part was getting the bolts started on the replacement pump, it's tight and down low on the 4.3. TYVM.

pretty nice video, I found it comforting to see each step, although nothing hard in this process it was good KNOWING there was nothing hard prior to starting...whole job about an hour for a first timer so seeing ahead really paid off...no hunting for "what's next" - Thanks a Bunch!!

This video is absolutely great!!! Thank you for taking the time to record and post.

[@1AAuto]

That is correct. Most accessory items driver by the belt make a whining noise when they are starting to go bad (alternator or power steering are common as well) so double checking everything would be definitely recommended.

[@1AAuto]

@BloodandSoil1 Usually when your waterpump goes bad it leaks anti-freeze from a small weep hole near the front of the pump.

[@xUNLUCKYxSEVENx]

thank you so much for this video, they were trying to charge me $650 for this at the shop, so i ended up doing it myself, bought all parts brand new, also bought a new alternator, and an econ book for college all for about $500

[@1AAuto]

+Saul Sanchez We're glad you found utility in our video. It sounds like you made the rational choice. 1aauto.com 866-403-3393

[@1AAuto]

@ballershanelle It may have four small bolts that hold it on. If it does not, and has one nut in the center as shown in the video, than you should be able to use it using the same method. Hope this helps you out.

[@1AAuto]

As long as the water pump is not leaking, you should be fine. If by chance you end up having to redo the job, you should definitely make sure that the water pump is torqued down correctly.

[@vanessavega8591]

Thanks for the informative video! Saved me $500 from the local shop. As others have said not that difficult more intimidating than anything. If it's an older vehicle go ahead and replace those belts and hoses. Since you have the thermostat out, might as well replace that also.

[@1AAuto]

The water pump bolts can be reused because they are not torque to yield. Also the water pump should have a gasket used if it is provided or in some vehicles, there is an O-ring.

[@joykirkeby3432]

THANKS SO MUCH THIS REALLY HELPED US!!!

[@1AAuto]

If you're not careful and you mix Dexcool with the wrong anti-freeze it will clump up in the system. If you want to switch to regular antifreeze you should flush the system out completely, then buy a decent antiffreeze. I had to replace the radiator in my Jeep and just made the switch myself. If was a good time to do it, because I had to also replace the water pump and hoses. Hope this helps you out.
