How To Install Replace Water Pump Chevy GMC Silverado Sierra Tahoe Yukon 4.8L 5.3L 6.0L 99-04 1AAuto




What do you think about this video?

Brian Harrison: 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!

knelitos23: @ 1A Auto Parts :I got a question man?...what about draining all the coolant from the heater core?..some people say they got problems getting hot air after changing the water pump/thermostat,and they recommend to drain the whole system(wondering how too?)..thanks for your video I'm trying to change hoses,water pump,thermostat on my 2000 chevy silverado..thanks again and please let me know if you got any other advise

Timothy Kamalu: Helped me do a Escalade now I got to do mine 01 Sierra.

David G: 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.

chris Maynard: im going outside to do this right now

1A Auto Parts: @BloodandSoil1 Usually when your waterpump goes bad it leaks anti-freeze from a small weep hole near the front of the pump.

1A Auto Parts: If you loosen them before you take the belt off it will put tension on the pulley and you should be able to crack them loose. 1aauto.com 888-844-3393

payan6251: I think its a belt tensioner pulley because I tried to spin it and it was hard to spin It didnt spin freely

Vonnie Reese: Very good video Mike, I have one problem, I changed out my water pump on my 2002 Silverado after 146,000 miles, I did everything correct the leak has stop, my question is that I didn't torque the bolts on the water pump, do I need to go back into it and torque the bolts? I have a feeling that I may have a little bit more torque than 22-24 PSI thanks again

John Letkiewicz: '01 GMC Sierra, 5.3 l. engine 225k miles. Never rplcd water pump. How can I tell if water leak is water pump or heater core? There is a very small amt of water in the cabin, but losing coolant under truck.

fvasquez01: How do I know if the problem is the water pump vs. the thermostat? Thank you

oXxLOUDOGxXo: Yes it does, thanks!

Cory Nichols: How long should it take a professional mechanic to replace the water pump?

Turco949: Would it be easier to install the thermostat housing on the water pump unit before installing the water pump on the engine? At least with the pump flat on a table, less chance of the housing o-ring shifting on you, etc. Good video though, thanks for sharing!

1A Auto Parts: Yes you are correct. If it's worn you may want to replace it with a new one.

1A Auto Parts: @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.

Jake Martinez: I would make a trace of the new pump on the BOX it comes in. Punch out a hole on the screws then insert the screw the for that place in the mock-up. These way the screws is replace to the same place from where removed.

bj45pressgod: That help out a lot

1A Auto Parts: It may be a little easier with it out of your way. 1aauto.com 888-844-3393

1A Auto Parts: There's a weep hole on the bottom of the water pump where the anti-freeze will leak out from when the water pump starts to go bad. We carry brand new water pumps for many different types of vehicles on our website 1aauto.com 888-844-3393 1aauto.com All of our auto parts include FREE SHIPPING.

Radiant Remodeling & Custom Homes, Inc: 2 questions: 1: Re-use the old block bolts or not? I've seen suggestions on both sides. 2: Hi temp silicone on gaskets or not? Again... seen both sides but I have been under the assumption that modern engines using o-rings need nothing. Thanks!

apexsrv: Thanks for the vid. Saved me about $400 doing it myself...with your help. I'll be using you as a resource in the future for sure!

ballershanelle: @1aauto. For an old skool 1985 GMC c1500 305/5.0H, removal of the fan from pump: i need to rent the special fan clutch tool from AZ or can i tap the wrench on like this video? I assume my clutch turns 1-way while holding the nut

payan6251: hi wat does the kit come with? just the gaskets? o do u sell the thermos tat because I didnt see it in ur website

battle623: Great Vid, one question though, would it be easier to install the thermostat before water pump mounting so that i dont have to work it in a tight/crampt position? it is only 2 screws.

BloodandSoil1: Question- For a few days I saw what I thought was a large puddle of oil under my 2003 Tahoe when I left. I took it to the dealer and they said I needed a new water pump. After I took it in it didn't leak anymore leading me to think it was just a loose bolt. If my water pump was no good wouldn't I hear something or the vehicle temp be high? I will buy a new water pump from you after seeing your video but wanted to make sure the clown at the dealer wasn't making this up? Thanks so much!

1A Auto Parts: @1981shooter1981 We currently do not have an auto repair video that shows this particular repair.We'll keep this in mind if we end up doing this repair in the future.

cruz sumerio: gracias , me ahorraron un buen billete , thanks

ssz33tt: Very well made video. I'm going to tackle this dyi on my next day off as my 04 Yukon Denali has been leaking anitfreeze for a month now. Question, do you have to use Dexcool as recommended in the manual or can I just use the green stuff antifreeze instead?

payan6251: everything seems to be well aligned ..wat could it be?

1A Auto Parts: @mryellowcrown 210 still isn't all that high. You may want to take a look at the fan, if that's higher than it usually runs to see if it's acting up.

1A Auto Parts: Thanks for visiting us on YouTube. Have a great day!

seq43: these gaskets dont require sealant? are all manufactures using these gaskets or is it unique to aauto?

1A Auto Parts: You should run what's recommended for the vehicle. You may want to flush the system out and replace the anti-freeze if it has over 100,000 miles on it.

1A Auto Parts: If the heater core is leaking, when you turn the heat on you can usually smell it inside the vehicle it will have a sweet smell, and you may see a leak on the passenger side. 1aauto.com 888-844-3393

baccracker: I am doing this today on a 2oo4 tahoe. Do you also recommend changing the thermostat, hoses and belt also? That is what I am planning to do.

1A Auto Parts: @SoccaGal23 The chain should last quite a while longer, but if you wanted to put a new on in as perventative maintanence. It's not going to hurt anything.

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.

Tom Davies: 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.

1A Auto Parts: It wouldn't hurt since you're already in there replacing the pump.

1A Auto Parts: @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.

el de san luis potosi: good video. how do i know if the water pump is bad. my tahoe start to leak coolant from the water pump but dont know if its just the seal or the pump its bad

Denise Brown: 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.

1A Auto Parts: If you're not sure you could have the dealer run your VIN number and they could tell you how which one your vehicle has. 1aauto.com 888-844-3393

1A Auto Parts: @Mr12mexicans Thanks for checking us out. Have a great day!

1A Auto Parts: 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.

1A Auto Parts: There should be a weep hole under the water pump that it would leak from when the water pump fails.

gotshirts2ink: Hello mike. Thanks for the video. One question. I have heard from a lot of people Not to use dexcool. What is the reason why they say that? Thanks again

1A Auto Parts: This video would be the same for the 4.8,5.3 and 6.0 motors. If you have the 5.7 the the process would be different. We carry water pumps for the 5.7 on our website. If you need a different one we may be able to get on for you. Our toll free # is 888-844-3393 Here's a link to the 5.7 water pump for your Chevy Tahoe 1aauto.com/1A/WaterPumps/Chevy/Tahoe/-/-/1999?utm_source=youtube&utm_medium=youtube&utm_campaign=1ATony

beeroosterm: Water pump housing O-ring hint: put some gasket adhesive on the housing/let it dry to ensure the o-ring remains in the groove upon installation...
