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

[@jaminburkholder9026]

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

[@manlymcstud8588]

yeah, they design these things to be used with 'special' tools so shade tree mechanics can't work on them, so they have to buy that stupid tools or figure it out on their own. hopefully there will be 'right to repair' laws that makes this abhorrent practice illegal.

[@rayscaparo]

@@manlymcstud8588do you really need the foot pound torque wrench to tighten the water pump or can you just use a regular ratchet

[@ianconley6673]

​@@rayscaparolol you dont wanna under or overtighten the bolts. Reason: when the system heats and cools the bolt holes and and things expand with heat and shrink with cool so when it does this if you overtighten things it wont have that same grip on the bolts to where they dont come out...when you overtighten bolts esepcially on aluminum it wont hold the same afterwords if you undertighten all you have to do is tighten it right. On soft metals you dont want to take that chance of overtightening

Great tutorial, many thanks.

[@bigredhead87]

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!!

[@gfdfperte4248]

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

[@Outlawjosiwales]

I believe mine has had a slow leak for months but yesterday it started leaking more made the belt squeal bearings went out and started rocking so I replaced the water pump never did really like a lot of coolant just enough to smell in evaporated before it hit the ground

[@gfdfperte4248]

ok

[@MarcosRodriguez-pm1jt]

Thanks man great video lots of help

Do I need to replace clutch fan

[@Mr.Stroke0331]

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.

[@smoejith9283]

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

[@All2Skitzd]

Thanks, videos really helped

[@kjemradio]

***** 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.

[@kjemradio]

The temp it was running at was about 160 when we purchased the Trailblazer earlier this year. The pump gasket is what failed, and we are sure this was OEM considering it has over 200K miles on it. As for the coolant, we didn't by the pre mixed type. We got the standard concentrate and added our own water. So it might be possible that too much of the concentrate was added, though it is hard to tell. The male portion of the sensor connector (at the wires) itself broke off and part of it is still stuck inside the female portion. We know we will have to replace it due to that.

[@raphaelvalencia5028]

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

[@williamjones2811]

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

[@genleechoj6546]

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

[@itsgeraldc9085]

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

[@maverick4045]

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?

[@zaid3ssaf1]

I use 3/8 inch drive ratchet or breaker bar to release the tension off of the tensioner pulley

[@meanf1502]

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

[@andreszamora2251]

Where I can purchase replacement bolts for my water pump?

[@newyearbaby100]

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

[@AirtexFuelPumps]

On the vehicle in the video the fan clutch, while facing the vehicle, turns to the left, counter clockwise. This is not always the case. Better to research, as you have, which way the nut turns.

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?

[@joemack477]

Airtex/ASC Performance Pumps, Thanks for the information. I finally removed it with a universal tool I rented. This was my first time doing this and it saved me almost $600 dollars. I rented other tools as well but they were meant for Ford vehicles not GM. But I'm glad I got it figured out along with your help. Thanks again

[@fyrfox2000]

How much coolant does it take?

[@meachy]

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?

[@karlos6628]

+Airtex Pumps - was doing that same job for someone-none of the rental tools from auto zone-or other parts stores help-,where can I buy the tools to remove the fan from the water pump-thanks.

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 .

[@WannabeOperator]

glad Im not the only one to catch that. it literally says DEX COOL on the damn radiator cap. AND on the overflow cap

Super Chevy if the manual says only dex cool you only put dex cool cause any other liquid can damage the inside then having it flushed

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.

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

[@kenlamar6163]

U can use a flat head screwdriver

[@jeremeyslayton9862]

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

[@AirtexFuelPumps]

The fan clutch is a electric viscus clutch. The clutch does hold a fluid that, when the seal fails, will leak a oil like substance.With you stating it is loose. It sounds like it is time, actually past time, to replace the clutch.

[@AirtexFuelPumps]

@@jeremeyslayton9862 Engine oil is not part of the fan clutch / cooling system. If you are leaking 2 quarts of engine oil overnight It should be rather apparent where it is coming from. Take a good look at the front cover ( the water pumps sits in the front cover), next I would look at the valve cover for the leak.

[@peterrams121]

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

[@AirtexFuelPumps]

Not in this application. There are many water pumps that are driven by the timing belt or timing chain. This is not one of them

[@dlwaugh]

Is this the same process on a 2008 Trailblazer?

Dan Waugh, Yes, this would be applicable to a '08 Trailblazer with a 4.2 inline 6.

[@gfdfperte4248]

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

[@reekayeat770]

Can you explain this further.. you DONT have to remove the fan clutch???
