So I have a 2015 honda civic ex and everytime I drive their's this chain rattling noise coming from the right side area of the passenger side, it's only when I accelerate around 1500-1800 rpms once over that it goes away but not completely until I go bck to a lower speed. I already changed the tensioner,idler pulley, the harmonic balancer, on that area. But still making the noise while I drive also before all this I took it somewhere else and they said the tensioner had playback and forth but since then got it replaced brand new oem and still making noise.

How many miles? Is it the original timing chain?

It has 101200miles and yes original timing chain.

Only does it when I drive and when I took it to a repair shop they said it might be the power steering or alternator or water pump but mine is an eletric power steering and the alternator we switched it out and tryed a new one and it still made the noise, the water pump is the only one I haven't changed

 

[bryanbarraza45]

I have a video of it let me see if I can post it and it's hard to describe its more like a humming sound. I not sure how to add a video of it on Herr

It even does it when I put my car in drive but if I have the emergency brake on and rev it too those rpms it will make the noise

If I were you, I'd take the serpentine belt off, and spin that water pump by hand and see how it feels. Either that, or just have the shop replace it. If it is failing like mine was, you don't want it to blow when you're driving, because that caused half my coolant to dump out.

Ok got it thank you. will do, that but also when I took it to the shop they power braked the car and heard the noise when they took off the serpentine belt the noise went away and as soon as they put it bck it made the noise I changed the tensioner, the idler pulley, harmonic balancer, changed the alternator but ran the car on the street and still made the noise so it wasn't the alternator either so the only two left would be the water pump and or powering steering pump but like they said to me, Mine is electric so their's no fluid to add to it so maybe repair the water pump like you said if that helps? I mean my car hasn't overheated or anything which is good.

This car has an electric rack, no ps pump

Ok thank you lol, I guess I'll just change the water pump and hope that's the case 🤞🏽

 

[bryanbarraza45]

Yeah for what's it worth, mine wasn't overheating either. Water pump was working fine, the pulley was still spinning, just noisy. And then I was driving and the pump bearing exploded and the housing cracked, coolant dumped, belt came off and whipped around wildly, shredding the hood insulator.

Oh, dame sorry to hear that about your car. Mines been making this noise for who knows how long and I dont even know when I noticed it either it really just irritates me that I took it to so many ships and ppl can't find the problem and they hear the noise when I replicate it.

 

[bryanbarraza45]

No worries, it's good as new now. Still think it would help to post a video so people can help diagnose it.

Trying to but I guess on here it only let's me upload 20 mb and the video I have is 70 so the file is two big unless you have an Instagram that I can send you the video or an email by any chance

It's the one video in shorts

 

[bryanbarraza45]

was the pcv changed with an aftermarket one?

the non honda replacements rattle like hell at certain rpm's had this issue on our 2015 EX and it drove me crazy until isolating it with a stethoscope.
pcv is in the back passenger side on the R18, rubber hose going to it.

I'm not too sure honestly still trying to learn more about my car but posted a video of how it sounds on YouTube

 

[bryanbarraza45]

What's pcv sorry still learning? And yeah, if you saw the video that's the noise it makes everytime I accelerate around 1500 to 1800 rpms

PCV
a quick test is pull the hose off the PCV valve.

Or maybe if you can send a picture or diagram of it would help please and thank you

 

[bryanbarraza45]

Passenger side back left corner of the engine...

careful not to lose the spring clamp from gravity when you pull it off the PCV.

Got it so just replace the pvc valve

Got it so just replace the pvc valve

I don't have a check engine light should it be on to tell me if it's the valve? Or maybe get an obd and see if aby codes pop up?

 

[bryanbarraza45]

im not saying replace it im saying pull the hose and see if the rattle goes away...

some of the cheaper replacements have a weak spring in them and rattle.

Ohhhh ok got it 👍🏽 I will do that tomorrow morning. Thank you I hope that's the case this noise has been bugging me for months and obnoxiously annoying hearing it when I drive through small streets

 

[bryanbarraza45]

sounds like waterpump bearing going out.

So just replace the water pump or is it two different parts?
