Water pump replacement on a Mazda 3

[@camarine32]

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 KZbin 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.

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

[@contextualmedia]

Repair manuals offer this information such as those offered by Haynes

[@Username-es1iy]

@@contextualmedia thanks I’ll check them out

[@reeggiee]

Thanks mate. Epic tutorial. Simple and clear.

[@FlowtnWitWalden]

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!

BEST DIY VIDEO IVE SEEN SO FAR FOR THIS PROJECT OF MINE! THANK YOU SIR! 👍

[@grizzy8312]

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 .

[@KingZoneOne]

Some (not all) water pump and many other O-rings/seals are meant specifically to be installed DRY.

[@Mech-Bandit]

You’re wrong, the o ring is installed lubricated. For this case with coolant

[@KingZoneOne]

@@Mech-Bandit 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.

[@FleetTech97]

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.

[@FleetTech97]

But don’t put rtv lol

[@urban_phantom7750]

I have my doubts when someone says NEVER. There are no absolutes, but plenty of big egos

[@andresmorales2414]

Perfect, of course, to the point and well explained.

[@andygeorge6076]

Never put RTV on an O-ring. Use some coolant to lubricate it, that's it. RTV is used on gaskets NOT O-rings.

[@Gfuel841]

Is it bad if I put some 😱😱😱

[@Adr_Jim]

@@Gfuel841 You should be fine, what he meant is that it's completely unnecessary.

[@fredrossi1334]

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.

[@confidentlocal8600]

KY glycerine-based lube works great on o-rings without damaging them.

[@djsmiley09]

Hey I got it all done! Thanks for the great video! Had no problems with the water pump, alternator or the pully. Easy install!

[@maumuse2211]

A very well put video Sir! Thank you!

[@djsmiley09]

Great video! I am about to replace the tensioner, water pump, alternator and both belts today (and maybe tomorrow). Wish me luck!

[@MegaSafetyFirst]

Great idea to do it all at once, good luck! 👍

[@djsmiley09]

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.

[@MegaSafetyFirst]

It's all pretty straight forward. I don't think you are going to run into any surprises.

[@stefanmeyers2808]

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.

[@lukecombs5242]

Great video very informative thank you.

[@salvadormanjate4891]

Nice job thanks so much four helping us

[@lakesidebc]

Great video! Thanks for putting this together.

[@wutUthinkinBro]

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]

Having the same issue. I'm using two wrenches with one braced against the engine bay

[@wutUthinkinBro]

@@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 🔧🔩 \ 🔩

[@gustavoarias6486]

Can you list all the tools you used to get done the work, also thank you your video is so helpful 🙌

[@growenywhere5346]

Having a great time) thanks.

[@philmares7474]

But how do you remove the pulley from the water pump it spins?

[@IzradiSam]

You should put some rod (screwdriver) in one of the holes.

[@505dylan1]

Why would u add gasket maker to a oring? Counter productive of what the oring is designed for.

[@javierdeantunano3340]

really good video, except the sealant on the oring area, you do not want to put any sealant on that area, may be some silicone grease or vaseline

[@chenesecarrington7769]

how long should it take to replace

[@thomasingebrigtsen1948]

When filling it back up with coolant you should run the heater to fill the whole system

[@mygiguser]

Great stuff man!

[@EduardoGarcia-cx5so]

Dos the pump make some noise when is bad?

[@MegaSafetyFirst]

If your car's water pump is failing, you may notice overheating, coolant leaks, unusual noise from the pump area, or a wobbly pulley.

I can’t say for certain. It may be similar, but I’m certain the torque specs will be different.

[@red-darkin]

the bolts holding on the pulley aren´t loose :( :( soo any idea?

[@MegaSafetyFirst]

You could try holding the pulley in place with a pipe wrench. That should provide enough leverage to get the bolts loose.

[@AndresGomez-cy6jn]

Andrés Gómez is it possible to remove the water pump without remove the pulley ?

[@MegaSafetyFirst]

Unfortunately not. The pulley blocks the access to the three bolts of the pump.

[@johnlucero9843]

Was both your upper and lower radiator hose cold? Mine are on my 2010 mazda 3 2.0 liter ?

[@MegaSafetyFirst]

Not that I remember. I changed the pump after it started to be noisy. With both hoses being cold I’d also suspect a failed pump.

[@FixItYerself]

open thermostat or low on water=cold pipes

My bolts for the pulley are so close to the frame how did you loosen yours?

[@MegaSafetyFirst]

I was using the open wrench, which you can see at 1:38. There was no other tool that I could find to reach into that cavity otherwise.

Maybe you could try to get more friction by placing an old rag between pulley and belt?

[@XxGreenBeXx]

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?

what is the best water pump for mazda 3 mdl 2010? thank you want to replace mine

[@automedic9781]

Mai Smith If you want the best order it from the dealer. If you want what will work, go order the OEM equivalent from one of the parts store

[@ihaveanunorigionalname]

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.

[@64wbryantex]

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 😡

It was a pain in the a$$ but I got the bolts off

[@laloarguello]

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
