    just a quick tip if you have access to a air hammer and a wide chisel. hit the chisel on edge of nut in the direction the nut turns off this method will remove the hardest fan clutches in seconds leaving only minor imperfections on the nut i never use my fan clutch tools anymore after learning this method years ago

      Regular hammer and chisel does the same thing.

    I’ve got a 2004.5 lly & just did the first water pump @ 382,000 miles but I also smelled the burnt engine oil after taking the balancer off & I have no known external engine oil leaks-also i had 2 deep gouge marks in my water pump housing as you mentioned cavitation

    Hardest part for me was the o ring on the pipe had to use silicon grease lube the heck out of it and the hole the n it didn’t want to roll .

      Same here. I have an lly and it's a bitch.

      Yes that pipe w/oring is rediculous-there’s only one specific position for installing it correctly or it’ll leak

    Thanks for both water pump videos. My 2005 is starting to leak so I'll be getting into this as soon as I get those tools you suggested. Thanks.

    • @mossman381
      @mossman381  9 лет назад

      +wyattoneable Those tools are a must have for the job.

    Great job sir. I am sure your video has helped many.

      I have more videos on my "Duramax water pump playlist" ruclips.net/p/PLZwy_pK9cqiPFYRA-UEwNzu6J9Und0y3E . Much more detail that this job. This was just another video posted to cover a few things I might have not shown in my other videos.

      Have you heard of some using a (red) injector cup o-ring on the top of the bypass pipe that goes from the bottom of the thermostat housing to the water pump? I am having trouble getting the top o-ring to seal.

    Do you have a tools list I could see?

    • @mossman381
      @mossman381  3 года назад

      I don't. You will need a lot of tools.

    By chance did it make a sound like a bad steering pump grind before you replaced the water pump?

    • @mossman381
      @mossman381  3 года назад

      I don't think they make noise. They leak when they go bad.

    no need for a flywheel holding tool or a 3 ft bar..just get a short 36mm 12point socket and a harbor freight earthquake stubby 1/2" impact, fits right in between the radiator and balance bolt, gets it done quick....saves more that an hour labor.
    .oh, don't mess with the thermostat housing pipe, just take off the 2 lower bolts and gently swivel it off to the side, these are a major bear to get back in without tearing the o ring seal, a real crap design..

    I removed the harmonic balancer bolt by putting the wrench on the bolt and hitting the starter. Came right off

    How long did the job take. And why do you have to pull off damper

    • @mossman381
      @mossman381  6 лет назад

      First time took me awhile. I can do one pretty quickly now. Watch all my videos and you will see why everything was taken off. I have a playlist and my videos are the best ones out there.

    Is the LB7 the same thing as the 6.6 diesel?

    • @mossman381
      @mossman381  7 лет назад

      The LB7 is the first version of the 6.6 Duramax.

      Veikra My s10 fan wouldn't come off either. So far the chisel and hammer have worked on 2 duramax's.

    What is the deal with getting a pump with a welded unit? The the non welded units have a known issue?

    • @mossman381
      @mossman381  8 лет назад

      They have been known to walk on the shaft I guess. Better to be safe than sorry. Merchant Automotive is the place to get all your Duramax parts. Check out all my videos on the Duramax water pump change. I explain it all. I feel I have the best videos of it on RUclips. I have a playlist with all of them in it.

    What is the deal with Chevy fuel gauges? I have worked on so man from the HHR, 1500, 2500 including the GMC now the diesels? Why are they so prone to failure?

      Bad servos easy replacing I also put led lighting in mine * the led display will start fading and go out but that’s just resoldering on the board .
