Showing how to replace the water pump on a Mazda 3. Before starting to work on the car please make sure the engine is cold, so that the antifreeze is ok to be drained. Remember to loosen the pulley bolts before removing the belt.
Thank you, this procedure worked for my 2007 Mazda 3 BK 2.0L where water pump had the chirping noise. Loosening the water pump screws did not work that easily for me as pulley kept rotating even under the belt pressure. I prevented the water pump pulley from rotating by using the trick from another RU-vid video: a long flat blade screwdriver placed between 2 of the 3 screws heads and used a 23cm long 10mm double ring spanner to loosen the screws one by one. To remove the pulley - removing the belt tensioner held by those 3 screws is a must.
@@Bandit-be7kp NOPE...YOU'RE wrong. I lubricated mine believing the same thing, and guess what happened. While driving after my car warmed up, all of my fluid came spurting out AT the O-ring, because the O-ring moved around. And no, I didn't over lube it. I came home, took everything apart, cleaned everything out, put the O-ring back in DRY, and I've been good since. Not every car or O-ring needs that, and even the Bentley Manual for Audi says to put it in dry. As you press the pump in, you gently twist it back and forth to keep it from binding or rolling. Lubing it caused mine to roll. That's it.
Hopefully no one takes this advice. O rings always need some sort of lubricant. If you ring lubricate them the o ring will roll and cut itself. Gaskets on the other hand are usually installed dry unless specified.
The rtv is mostly for the flange portion of the pump. But like mentioned above, unnecessary on the outer surface of the O-ring. Could even negatively affect the function of the O-ring.
In lbs, ft lbs bruh I may not have the same year as you do but it’s probably the best reference I have to go off of thank you so much. It seems like car manufacturers don’t want us doing our own maintenance because I could NOT find any information on anyone this anywhere. Any link or further information you can’t find on these “lifetime” mechanisms is highly appreciated and you should definitely make videos on. You have a follower for life
Excellent step-by-step instructions, even give all the torque settings, thanks! The only thing I would skip the RTV on the water pump O-Ring. Did that on my Honda coolant connector pipe that sits down below the intake - back of engine. PITA to get to - had to do it twice because of the failed seals with the RTV. My bathroom sink faucets use O-Rings without any RTV and they stop the flow of water just fine!
Great video , well illustrated , As noted w/ exception Re: `O ring , it may be installed dry or w/ always available a little 'spit works fine . Thanks again .
Anything I should watch out for in these repairs? I am also going to clean the throttleboy and EGR valves. Any tips on that? And I know the car will be all wonky upon reconnecting the battery and isnt actually dying and is instead reprogramming and needs 20 minutes or so to idle, then idle under load to recalibrate.
I just finished replacing my water pump on a 2011 Mazda3 sport, got done at 10:30 pm and it was -11 degrees celcius. There doesn't seem to be as much space between the front of the motor and the frame as shown on this video. the hardest part was trying to drain the rad, the plug is bottom left and I unscrewed it all the way and no fluid came out and I couldn't get the plug out. so I just covered the alternator with a plastic bag and as I took the pump off I let it drain into a container.
Great video so far, i’m stuck on the three bolts on the pulley as it keeps rotating as i try to loosen them. i’m guessing a second 10mm wrench is needed for leverage.
@@Empire_of_Ravens i had to use a long handled wrench and put it between two of the bolts to stop it from moving, so i can loosen the third bolt, like this: pull wrench towards you 🔧🔩 \ 🔩
@@FlowtnWitWalden The pumps are made by other companies. To Ford/Mazda's credit, the pumps are pretty easy to change and only cost $30. It's the only repair I've had to do on the car.
@@MegaSafetyFirst Great video by the way. I've done both the thermostat and pump on my wife's 05 mazda abd her best friend 07 mazda 3. Seems to be a pattern. How many times have you replaced the AC compressor?
My water pump is just making a squeaking noise when the engine is on idle. It's pretty annoying but the car still drives perfectly fine. Not sure if completely changing it out is what I want to do.
That music is terrible...... you didnt mention anything about the oring getting caught.. i just did this job as part of another one and when i reinstalled the old pump( wasn't replacing it) the oring got pinched and cut in half allowing coolant to puke everywhere. My favorite lube to use on orings is silicone spray. It is effective and wont do much to anything you spray it on by accident. if you are having problems getting the pump out just remove the 2 bolts for the pass motor mount and jack the motor up a bit to clear the frame rail better.
my pulley keeps spinning even with my belt on it. PLEASE HELP!!!! edit: I CANT GO TO A MECHANIC I HAVE NO MONEY IM OUT OF WORK CUZ OF AN INJURY. I MAKE MONEY WITH MY CAR I NEED HELP ASAP PLEASE
@@brandontaylor8082 I figured, I’ll attempt it tomorrow. I’ve just been using chisels,prybars, transfer pipes with a hammer beating the shit out of it and it’s only come out 1cm.
Yeah, the bolts holding on the pulley are not loosening even with the best on I even used a screw driver to hold the pulley with the other two bolts and still nothing 😡
Lexi Star coulda just removed the motor mount bolts the ones that are mounted onto the actual car itself then lifted the engine with a jack from the left side and that will expose the waterpump pulley then just use a 10mm socket or 10 mm wrench with the belt still on and hold onto the pulley for more leverage to loosen the bolts
Currently doing this right now any tips?? Been using chisels and transfer pipes with hammers I’m gonna pick up a chisel hammer tomorrow and see if I can get it off
MegaSafetyFirst I got it done, had to get a friend to come and he was holding one from the top and I loosened the other one from the bottom. But just for future reference, would your idea not damage the belt?
