What do you think about this video?

Veracruz mx: What's is thermostat size of a 2000 silverado 4.8? 

stewnta: I know this vid has been up a good while but thanks for the help. I think my water pump may be starting to act up. Everytime I start the engine it sounds as if the engine is tweeting like the old VW Bugs from back in the day, more so when i step down on the gas. Is this the indicator?

Mike Blake: Great video with good lighting,a pleasure to watch. Thanks

Josh Tebbs: Great video Mike. Do the bolts on the tensioner need to be torqued when reinstalling?

AA1PR: many thanks

Umar Malik: Thanks for sharing... really helpful... 

Federico Velasquez: Thank you for posting this video, I was wondering on the drain and flush how to find the cylinder block drains on both sides of the block in order to drain completely and refill, but there's nothing anywhere on the internet. I have spent 2 hours looking for them.

mickster boone: Thanks for posting this, it really helped me.

Scott Bender: 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.

Russ Glover: 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. 

Peter Horn: 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.

Vanessa Sandoval: thank you for this video it realy helped me to fix it.god bless you.

Mike Paiva: Good video made my repair job very easy , thanks.

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!

Robert Gallo: Thanks 1A Auto, you are truly the #1 

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

Brian Harrison: 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!

Chad Welsh: You guys rock! You help me make money period point blank.

Jason Starr: Nice job on the video. Especially tough doing the work and being the camera man too... have to do this to my 2006 4.8 L.. ... 100,000 miles and it starts falling apart.. lol... 

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

elguapo21954: Outstanding video. As I attempted to remove the fan with a crescent wrench and tapping with a hammer, it would not break loose. As a matter of fact, the whole pulley would move as I was hitting the wrench. I did have the belt still in place. I would appreciate any suggestions. thank you.

MrCrazyboyusa: I replace my water pump , but my coolant light still on . Any idea guys or how long computer takes to reset?

Blaine Yoakum: when taking off the water pump how do you tell if the water pump is bad or not? I may just have a seal thats bad. Thanks.

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?
