A Toyota Master Diagnostic Technician Explains why do Toyota water pumps leak and how to prevent them from leaking prematurely.

In this video we take a look at Toyota and Lexus water pumps and common causes for leaks while we take apart another leaking water pump on this prestine low mileage 2007 Lexus LS460.

The super long life coolant just like the long engine oil change intervals can be a heavily debated subject. however it doesn't need to be.

Change your engine coolant every 50k miles or 5 years and you significantly reduce the chances of leaks caused by acidic coolant.

  • @MrSweetHart6976
    You're really taking these videos to the next level, in visual quality but also educational information as well
  • I am an old mechanic now 78 years old, I just love 💕 watching your high quality technical videos. You are an absolute master. I just wish I worked under someone as knowledgeable when I was doing my apprenticeship in Australia. I just love to watch your videos.👍👍👍👍👍 I just ❤❤

    " I have to go wash my hands before I get into the vehicle", everything AMD does exudes quality and care! Always a pleasure to watch his videos.

    I had a good friend who use to own a radiator repair shop. He once told me if people would " Spill and Fill" their anti freeze every third year of the vehicles life, he would be out of the business.. Everybody thinks about their oil maintenance intervals but never think about cooling issues until bad things happen. That has stuck in my mind ever since. I buy my anti freeze when I find it on sale for future use. This is just something to think about taking complete care of your vehicles.

    Ya when I changed my alternator the other day on my 2010 corolla I barely bumped the radiator return line and snapped it off. I drilled it out with a 25/64 drill bit and twisted in a brass fitting from lowes hardware and jb welded it for 24 hours and it’s actually stronger than that thin plastic that was original.
  • @flavellinator
    Like a great surgeon... Detailed, logical, and careful manners! Excellent explanations...
  • @IsleOfFeldspar
    I look at this guy’s shop and it’s immaculate. Not a drop of oil on the floor. That means he’s a nightmare to work for. Even my heartbeats per minute would be counted if I worked for this guy. But I love the knowledge and content.
  • I learn so much from your videos. My 4Runner is a dream vehicle, and I credit you and my great mechanics for 100% peace of mind when I am off road in the desert.
  • @p_r_g_m_r
    AMD's videos have a perfect mix of theory and hands on with some great caveats and knowledge sharing that only comes from ton of experience.
  • @mailmanjoe
    I always wondered what you could do to attempt helping prevent a leaking toyota water pump! AMD comes through again! You're a gem sir! 💎
  • I wish I had a mechanic close by, that had half the knowledge and passion as yourself mate
  • @danielhanna160
    I've learnt so much from you about my LS460. Luckily mine is in great condition, a low km example and well looked after like this one. Thanks for these Videos!
  • @iamredrunt172
    Coolant is definitely an issue. You hit it on the spot. I've got 3 vehicles, pushing close to 200k without any issues. I change my my coolant once a year, with vehicle recommended type. So many different types. And yes use OEM parts. Preemptive maintenance is the best. BTW. That is a complex job. You make it look easy because you've done this for a while. I give you triple thumbs up. You know your stuff.
  • Your videos are a treat that I look forward to a very much! You’re like an old friend that comes into my space to visit! You’re like an incredibly patient teacher! :-)
  • I heard a new sound under my hood. Not loud. No visible leak seen when I looked down. I am learning so much from you. My coolant and water pump job was recently done. I live in desert southwest. Thank goodness for my honest fair and reliable service garage!!!
  • @crabbycripple
    Another great video. The advice and insight you provide is priceless, very much appreciate your experience and expertise.
  • @donkmeister
    On the coolant fill and bleed, the correct procedure for the ls460 is right there on the label on the header tank. Made it very easy on my first ever radiator and pump change 😀

    i just love the way you explain things with so much detail and so much passion thank you
