How to Install a Water Pump: 2002 - 2009 Chevrolet Trailblazer 4.2L L6 WP-9234 AW5097 

this video is sweet...it saved me $250!!!!..it took me about 3hrs. and never worked on a vehicle before. note: i didnt use any special tools-to loosen the tensioner a 3/8 inch socket works perfect- to loosen the fan nut i used a 1 7/16 inch open end wrench and a big tire iron to hold the pulley so it cant move..with 2 guys it wasnt very hard to loosen

Man those water pump jobs are evil. Yall made it look so quick and easy. Great video. 👍👍

Exactly the video I was looking for. Very detailed but quick. Can’t thank you guys enough!

This is so concise and well made! TY! turned my half a day job tomorrow into an hour job!

Easiest Video to Follow on RU-vid for this procedure. Thank you!

This video was a big help.

Thank You for this info, saved me a small fortune

Used this video today for my 2007 isuzu ascender. Awesome

Great tutorial, many thanks.

Thanks man great video lots of help

Great video!! Called the local mechanic and they told me almost $600 to change this water pump!! I also changed the fan clutch. This would have cost me $1000 with parts and labor to change the fan clutch, water pump, and belt. Thanks for a great video!!

This guy shows how a great video should be done!

GM should have put a TWO Piece Fan Shroud in this truck. Repairs would be real Easy.

Thank you! For finally showing, and doing in a clear, easy way to understand! Nothing else is worth watching. C

Great Video!!!

You make it look so simple.

Thanks for the video it's help me a lot that you

Thanks, videos really helped

Awesome video thank you

Great video it was really easy to do only took me about 2 hours total a shop told me they billed the job for 3.1hrs only issue I had was putting the fan shroud back in and getting the bottom tabs back in the proper holes... Thanks

best video yet,

Best video on RU-vid for this job

thanks for the video... save me $$$$$s i didnt have to spend at a mechanic shop... most appreciated

Thx alot. This saved me 180.00. GOD BLESS U ND THANKS ALOT FOR SHARING. LOL NOW I DNT HAVE TO WRRY BOUT CONFLICTION WITH BILLS

Great video now I know it's doable

Nise and smart work , thanks so mush

Thanks! Used the torque specs

Love the video... but for next video PLEASE explain what tool you are using(like size)...other then that no complaints

Awesome video! What is the name of that tool you use to hold the 2 nuts so you can open the fan? Thank you.

thank you for the video... helped me out alot

Should you replace the fan clutch and the water pump at the same time? Mine started knocking and when i check the fan play it’s wobbly as hell.

The 210 Mark on the Gauge reads about 197 -205 by reading my OBDII Scan Tool

great video. hope it only takes me less than 5 minutes. haha

Do you have links to the special tools you used in this video? Clutch wrench, pulley holder and tensioner tool?

Great informative video. I'm going to attempt to replace my water pump this weekend. 2 questions: 1) i need a fan clutch wrench to remove the fan, correct? 2) what is the name of that special tool designed to remove tension so you can take off the the drive belt? is it called a Serpentine Belt Tool or Tension Release Tool?

I replace my water pump today. But now when I turn the heater on my rpm lowers until the car shut off. Maybe I need to bleed the coolant better

I could be wrong but isn't that the transmission cooling lines in the brackets connected to the shroud? You said power steering, just curious

the trailblazer vortech uses dex cool only if you use the 3 year 30,00 mile green fluid you must flush the block. dex coo can not be mixed it will turn into sand and cause a blockige.

found 2/5 of my bolts broken off 1/2 way stuck inside thhe block... what remains of the 2 bolts dont grab at all.. the 3 remaining will hold any clues for repair..

what tools are you using to get the fan loose? the 2 wrenches? I tried with basic tools, but I can't get any leverage to get that sucker loose

did you make them tools to take the fan clutch off an that wasn't the right coolant either my 06 trailblazer takes the pink stuff

Where I can purchase replacement bolts for my water pump?

Hello, great video. Thanks. I just changed my water pump using it. I had one snafu. I snapped one of the bolts (mixed up 35 foot/pounds with 35 inch/pounds) I didn't have the tools to attempt to remove it (snapped below face surface) and I had to get to work, so I put everything back together to see what would happen. I couldn't find any leaks. With the heat on the temp is around 160 degrees. With the heat off the Temp is below 210 degrees. Withe the A/C on the temp was barely above the 210 degrees mark. The ambient temperature was 95 degrees, not sure if that matters or not. The only thing I can see as out of the ordinary is my top hose doesn't have the same tightness from pressure as it normally has. I know I need to get that broke bolt out as soon as possible, but do you have any recommendations on it's usage till then?

How much coolant does it take?

nice video. is the fan clutch reverse threads?

Do I need to replace clutch fan

Great vid, BUT I dont recall my teachers playing music during a lesson. Very distracting!

What tools did you use to separate the pulley from the fan. I've tried the universal tool but I could not loosen it. Any suggestions?

Great video bit why would you put regular antifreeze in a gm when it calls for dexacool their goes that motor

I put a new water pump in yesterday and the truck runs much better. Runs cooler and Runs better. Most people told me not to put a new pump in and just use stop leak. Make sure you guys use your OBDII scan toll and read the WCT Water coolant Temp to get the reading so you know what the real temp is when your temp meter shows 210

I would like to know why he took out orange coolant and put in green? Is this a aluminum water pump or not? ( I clicked here for how to flush a cooling system but only got vid paused. LOL :P But good helpful vid in the end )

the coolant bottles says "do not add water" why did he add water?

Pretty sure mine needs to be replaced, but it just started having problems a week ago. Between college, my wife's appointments, kids school, and work, I don't know if I have time to repair it.

Ya you forgot to bring up the rubber flaps at the bottom of the shroud. That would of been helpful.

If you are facing the fan from the front of the truck. What way do you turn the nut, clockwise or counterclockwise

Hi my friend what’s the tool you use for tension belt

Fill your over flow up all the way and run it for a few days if the blazer needs water it will take it . Use a good Prestone at 25 below . I do feel a Ounce or Two of prestone stop leak when you do a water pump. not the full can I say two Oz max

Any boddy knows how much it is the cost for Fix the water pump?

I thought all GM vehicles used the orange Dex cool coolant. not yellow?

How much time does this usually take start to finish?

Great informational video the only thing wrong here is you should not be using green coolant . The engine requires dex cool which is an orange color .

Power steering lines??

se pudo resolver por su vídeo

Since it's a GM vehicle, aren't we supposed to use Dexcool?

wait did you say 218 or 18 ft lbs of torque on the pulley?

Is this the same process on a 2008 Trailblazer?

I changed my fan clutch and water pump today when i put everything back together my heat comes out cold and my car is over heating.. any idea of what this problem could be?

The video is good but is lots of miss information, like some of the people saying, GM use they own antifreeze not just any antifreeze, the other thing is,we need to know what kind of tool we need to get and sizes.

sweet it only takes 4 and a half minutes

pulled radiator, done 2.5 hrs. 👍 I'm exsperenced mech. no torque wrench needed.

aren't those the trans cooler lines?

Our isuzu vortec 4200 has loose fan and oil leak but we cant figure out where oil leak is at. It leaked onto the belt and slung oil all over front of engine. Could it be comming from behind fan? There is oil behind fan clutch

This might be my problem but unfortunately I don't have the funds right now to complete it

Does changing the water pump affect the timing? Noob here.

you forgot to mention just use a big screwdriver instead of that crazy tool, that when replacing all this it needs to be about 24 degrees F and you have to do it outside, and have some real hose clamps handy for when these cheap spring clamps break on you....

Thank for the Video, But For the first time Do it your self person you were not very clear on removal of the Shroud. The Shroud has to be pushed toward the rear of the car and the Transmission lines are in the way most of the time, The Top hose connection on the Radiator is in the way of taking the Shroud out, you just cannot pull it up. I see the you left that part out. Next you do not have to remove the fan blade from the Clutch. Just loosen the bolts so that there is about 1 1/2 treads still in the hub. This keeps the unit together and much easier to handle

I changed my water pump and now my car is overheating with water all over the place can any one help?

RU-vid should be in every tool box. lol. Mine wasn't nearly that easy, as the fan shroud didn't simply lift up and off, but otherwise it was that straight forward.

Uhh O K . Master Mechanic why are you calling the Auto-Trans cooler lines on the fan shroud “Power steering lines ? The power steering lines never touch the fan shroud .

***** Couple quick questions. We just replaced our 2002 Trailblazer's water pump, but now the temp is reading 210. We bled the system for a good 10 minutes (in fact we did this a few times), but it still remains high. No leaks, and the pressure at the cap is good. Overflow was filled to capacity, as was the radiator. We are thinking it is now a faulty thermostat, but is there something else we should check? Also there is a cable just below the oil fill (kinda under the black cover). The connector head broke when the belt was removed (you can see it at 0:39 in your video by your hand). We do not know it's name so we can replace it. Might you have an idea what it is called? Thanks.

Hmm wrong, wheres the comment to replace belt tensioner and idler pulley to prevent prenature water pump failure?

ive see guys do this without taking off the fan shroud

Is it the same 2005 trailblazer..? Sorry for the stupid question, I just want to make sure.

What if i don't have a torque wrench?

The bolt snapped on the water pump install around 20 ft lbs. He says to criss cross at 35 ft lbs then go to 89 ft lbs. If everybody else here is so pleased with this vid than I'm gonna assume I'm the only one that used a torque wrench.

Do not torque in the bolts for the water pump at 35 inch pounds who of my five bolts snapped

book time on this is 3.1 hours?

I really hope you didn't just mix dex-cool (orange) with universal coolant (green).....That will clog the entire cooling system

Need to emphasize that the torque is INCH-POUNDS, not FOOT-POUNDS, to help DIY'ers not snap bolts in the engine block. Maybe you can re-edit to make this a major flag to less experienced mechanics. DAMHIKT

“Use this tool that nobody has and is 1200$ 😀👍”

Don't do like this guy did with the coolant. Use dex cool 50/50 not the green coolant.

* 218 in lb not ft lb

It's 2018 people, use ratchet wrenches.

dude it would help if you would describe how to take the fan clutch off instead of just saying you have to remove the fan clutch and not go into some detail on how to do that. your video doesn't accurately show it and it is pretty frustrating. if you want to make a video do it thorough. wtf

you just filled that trailblazer with green anti freeze wtf... it literally says DEX COOL on the radiator cap AND on the overflow cap. Why are you using green antifreeze that is not the same as orange dex cool.... literally working on a trailblazer now someone put green antifreeze in..... How hard is it to read the cap??

Got damn why do you have to remove all that shit

Your shits already pre-lose and you skipped all the hard parts. But nice video.

Piece of Shit Design leaves no room to work. Drop the fan clutch and you will need a new radiator guaranteed.

He put the wrong coolant back in at the end that green is NOT dexcool glad that is not my ride.
