How to: Water Pump & Coolant Removal + Replacement on 2.5L Mazda 3, 6, CX-5

[@4747-u2r]

These engines are amazing reliable and brings a tear to my eye to say they are user friendly ! DIY work at home easy peasy ! I am glad your making videos for the sky active 2.5 for our years keep them coming !

[@footprintsinconc]

Thank you for comment! Please help me out by liking & sharing the videos so that we can get this out to as many Mazda DIYers!

[@Dyl_Cam]

Reliable, yes, easy to work on, very debatable. just a tight space

[@Nordestada]

​@@Dyl_Cam​, Agreed. It seems too difficult for a water pump; not sure mechanics would appreciate that either. I just hope mine does not leak or go out.

[@TheNDex]

my brother, you are a god send... an automotive shop quote me for $1325 for water pump, thermostat, flushing coolant, and inspection. I told him that was a steep price. Tried to get another quote from mazda dealership for water pump, he told me his parts guy is not there, I'll let you know tomorrow. I watched your video 3 times, I'm changing the water pump tomorrow! THANK YOU!

[@footprintsinconc]

I'm am extremely happy to hear that you watched my video 3x!! and most importantly, have decided to do the job yourself! you got this, take your time. please share, thx!!

[@TheNDex]

​@@footprintsinconc thank you will do! I'm curious where did you buy the shop manual for Mazda?

[@footprintsinconc]

@@TheNDex i don't have a shop manual, I found this link online and was able to download some docs. that site is longer working, but check out: www.mazda6club.com/threads/3rd-gen-one-stop-shop.307129/ www.mazda6club.com/threads/2014-full-interactive-workshop-manual.305890/

​@@footprintsinconc thank you bro much love

[@footprintsinconc]

@@TheNDex let me know if you find a working website with the manual...i should have downloaded some parts when it was up :)

[@swainsongable]

This is exactly what i needed to know. Likely won't do it myself (ill probably have to replace it before spring in Canada) but enjoy the learning an understanding what needs to be done. Really appreciate yoyr presentation and clear delivery. Thanks man!

[@footprintsinconc]

Thank you for the kind words!!

[@giorockmaster]

For any body struggling to remove the pump. Put a wrench on the lowest bolt of the housing to help rotate the pump left and right while pulling it out at the same time. Thanks my guy, your video is great!!

[@footprintsinconc]

Thanks for the tip and kind words!

[@collintan7858]

TIP.... at 16:20 time marker, you can see on the new water pump there's a hollow hole at the top of the pump, that's the pulley alignment guide and stopper. If you insert a big enough bolt or a 3/8 socket extension this will prevent the pulley from free spinning and will allow you loosen or tighten the pulley bolts. **The water pump belt is stretch to fit, once its remove it should be replace with a new belt. When changing a water pump it's always a good practice to change the thermostat at the same time, which is located on the opposite side of the lower block. This will save you a headache and $$ later. *** Clean your intake valve, its important on GDI engines. Mazda added an Oil and Air separator on 2014-2022 models, however they arent very effective at all. You will still have tons of carbon build up. If you want your engine to last or get better MPG clean the intake valves and system. My 2014 Mazda3 had 70K on the clock, I noticed my MPG dropped to 32-34mpg on long highway drive (400 miles) after cleaning the intake valves/system my MPG went back to 39-41 mpg driving at 70mph.

[@footprintsinconc]

nice! thank you for sharing!! i really appreciate all the input. a) i know of the that hollow hole, but i found that since i didn't have side access, it was of no use. can't get two things in that tight space between the fender wall and pump with two hands...could only do it as i show in the video. b) couldn't agree with you more! i did the same, i've got that mentioned in my notes and have the link to the video in the descriptions as well. C) i would love to do that...can you share more on how to do that and your thoughts on adding an oil can?

Beautifully put together video! Thanks for sharing..... Btw, did you show the correct sequence of bolts when tightening down? I may have missed that

[@footprintsinconc]

i did forget to tell you that in the video, it should be fine as long as you tighten all 3 bolts. however, here it is in the diagram that is available on screen for 1 second...sorry: kzbin.info/www/bejne/kJfJi2Wto6qhqq8 at 21:29 the diagram labels top at 1, going clockwise, next bolt as 2 and then the bottom one as 3rd.

Thanks for this and the other videos about work on your Mazda. Great work Sr. At how many miles did you replace this components and also the belt tensioner and thermostat. Thank you and take care.

[@footprintsinconc]

Thanks! Please make sure you share and like the videos to help out the channel with the KZbin algorithms. this was at approx. 115k miles.

[@warfarewar8206]

awesome video thank you!

[@footprintsinconc]

Glad you liked it!

[@richardborge8541]

Thx for the excellent tutorial. What is the torque spec on the pulley bolts? Thx

[@footprintsinconc]

i just tighted with down without a torque wrench as there is no room to do that. one way to guage it would be when you remove the bolts, feel how tight it was...then tighten it right away and then loosen it again to get a sense of how tight you need to be when reinstalling the pulley.

[@Jeli_Lo-Fi_Lounge]

For future reference torque spec 21:30

[@TStark-xs5cj]

Are there any specialty tools you recommend that would have made this easier? I ordered water pump and thermostat a few minutes ago. I know an angled box wrench would help with the tensioner. I just replaced the belts about a month ago

[@footprintsinconc]

no special tools needed! you see the tools i used in my video! good luck!

[@mathieulaporte2897]

Thank you very good Video!

[@footprintsinconc]

Thank you for comment! Please help me out by liking & sharing the videos

[@Dyl_Cam]

When I try to remove the water pump bolts the entire belt moves, I'm pretty confused on what to do now

[@footprintsinconc]

i assume that you are trying to remove the pully bolts right? use a clamp or zip tie to squeeze the belts together (upper and lower) so that pully won't spin

[@macker0077]

Thanks for the video. For the pump pipe O-ring, a small amount of dielectric grease applied to it will help get it on the pipe as well as help make the insertion into the pump housing very easy. Had never seen such a small torque wrench. I'll have to look for one of those. Finally, did you purchase the Mazda Shop manual to help with the procedure or some other repair manual?

[@footprintsinconc]

Thanks for the comments!! here is a link to the 1/4" drive torque wrench. inexpensive. amzn.to/3qKGauT i don't have any manuals. I just look online for information and at times you can come across the information needed.

[@macker0077]

@@footprintsinconc Just a quick update to say my 2018 CX-5 was in for warranty work (Switchable HLA's had to be replaced - Mazda Service Alert) and while they were doing the job, found the water pump was leaking, and a Timing cover (oil) leak. Replaced the water pump and Timing Cover gasket. All covered under warranty. My vehicle only had 33,000 miles on it. Very low mileage in my opinion to have these kinds of issues arising.

[@footprintsinconc]

@@macker0077 nice!! definitely, with milage under 36k miles, all issues are covered under warranty. i agree that these issues shouldn't have occurred at such low milage.

[@justinnewton7168]

In the service manual I have, it calls to put coolant on the gasket/o-ring and dissuades any use of oil because it can cause swelling and leakage. Js

[@D7ME411]

Thx for sharing. Is it electric or mechanical water pump? How to tell the difference. Thx again

[@footprintsinconc]

good question. its a mechanical pump. its driven by a belt, it spins the fins, creating a flow. if it was electric, then there would be wiring going to the pump and it would have an electric motor on it.

[@mm-il8dg]

thank you

[@footprintsinconc]

You're welcome

[@daoudaqtash9243]

What was the mileage on your 2.5 Mazda 3 when you changed the water pump? I have 2022 Mazda 3 2.0 Skyactiv motor and it has 240k with the original water pump still working.

[@footprintsinconc]

That is awesome! I had 120k. It was still good buy it was on its way out...who know how long it would have lasted 10k or 50k miles...no one knows

[@timgifford4637]

Hi, thanks so much for putting this video together! Question about spraying the inlet pipe with PB Blaster-it wasn’t clear in the video where you sprayed and also did you spray it from underneath? Thanks again!

[@footprintsinconc]

You are welcome!! Thank you for the question. In the video, at 11:16, that view was taken from behind the water pump, while i was under the car. you will spray into that lip where the pipe is entering the back side of the water pump

[@stevew278]

Uhh...You spray it where it’s stuck 😂

[@marcosantacruz9086]

i thought i had commented earlier. the water pump number should be as follows: PEDD-15-010A it looks like the description has the tensioner part # instead. please correct if wrong

[@footprintsinconc]

Thank you Marco! I appreciate you pointing this out! updated the part number.

[@rpmautoreviews9249]

so is this the same for any model year ? 2018 Mazda 3 GT 2.5L ? and if same, how long should it take to do this, if you're a mechanic with a hoist ? asking because today I paid a mechanic for my stepsons car to change the water pump, and he pulled the it took longer than the rated time due to having to move some mounting bolts or some b.s. and charged me $100 more than the 1.95 hrs its rated for. I debated a bit, but gave up and paid it and now he'll never see my families 4 cars in there, for a $100 extra today. Claimed it took almost 3 hours. from you show here, I can't see it being longer than 1.5 hours for a mechanic with a hoist and tools. Going to google review the fckr, after I double check with my own mechanic friend (who lives too far for me to bring my stepsons car too).

[@footprintsinconc]

the SkyActiv-G - 2.5 L I4 engine starts at 2013 to present, see the link here: en.wikipedia.org/wiki/List_of_Mazda_engines now in a mazda 3, there might be less room becuase it's a smaller car, i can't tell you for sure becuase i haven't physically seen how much room there is in a mazda 3 engine compartment... having said that, it shouldn't take more than the book time. honestly, i think the mechanic should eat the time difference if he is charging more than the book time. the book can be wrong. i think if the mechanic wants to charge more the, he has to prove to you (that would be to lift the car and show you physically, why it supposed to take more time than the book.

[@footprintsinconc]

let me know what your mechanic friend tells you. thx.

[@rpmautoreviews9249]

@@footprintsinconc he said he doesnt believe it really would have been more than 1.5 hours even the its rated for 1.9 hrs, & no way almost 3 hrs

[@tyty0071]

Why was the reservoir tank designed like this being wrapped around by the wiring harness? Really stupid.

[@davidchin2497]

how many km is your car ?

[@manhduy3889]

Thank you, but how i know which one fake or real water pump in market

[@footprintsinconc]

buy OEM water pump from an online dealer. check the build quality of the part when it comes to you. in fact you can take yours to a dealer for comparison...

[@stevew278]

Fake or real water pump? If it’s not made of play dough I’d assume it’s real 😂

[@stevew278]

This is an hour and a half job not an all day job. Put the torque wrench away

[@footprintsinconc]

what made you think that this was an all day job?

[@noertdk9228]

You skipped some steps with your editing.

[@footprintsinconc]

just skimmed through the video, what step did i skip?

[@noertdk9228]

For one you skipped taking off the belt for the water pump. There’s a trick to it, using a shop rag to get it off track.. that would have been beneficial to know. Had to watch another video to figure it out.
