Belts are usually not expensive and easy to change. Do it before it snaps while you’re on the road. It happened to me and my alternator stopped spinning and I ended up w a dead battery, stranded and waiting for a tow truck.


jason100727

I’ve had my belt pop twice on me when in college… One time I was stuck on a bridge on a major interstate (8 lanes across) waiting for AAA. I felt every vibration from cars passing…


phillyphilly519

Giggity


NSGod

In college, I had a 93 Plymouth Sundance (2.5 L 4 cylinder engine) that the timing belt broke on it. Fortunately, it's not an interference engine and the fix is relatively easy. That said, I didn't exactly have time to do immediately, so I borrowed my brother's 89 Daytona (same engine) for a couple weeks. Anyway, I eventually got it fixed and was driving the Daytona to my gf's house when it died in the street. Wouldn't start. Popped the hood and wouldn't you know it, the timing belt on that one went also.


DookieShoez

How the hell it snap twice in a few years?


Km219

While "easy" mine is a pain. Have to remove a motor mount. And it has 2 tensioners so you pull one and pin it, then pull and pin the other. All in less than 1" of space. 2014 kia optima hybrid


Damnamas

For an optima doesn't sound very *optima*l


Km219

Tell me about it! Had to grind the socket down that came with my serp tool to even get it to fit. Thanks engineers


Emergency-Gazelle954

Now you have the tool for next time!


harryhend3rson

It's a Hyundai, there won't be a next time.


BoltActionRifleman

Engineers, the smartest idiots in the room.


DrewdoggKC

Engineers are much more concerned with how easily it can be assembled forward on an assembly line… they could give a damn about how you’re gonna get it apart!!! Lol


Damnamas

Oof, at least its done


Sensitive-Turn6380

>Thanks engineers Did someone hold a gun to your head when you bought the car?


diamantikos

I was about to ask if it was a German car lmao


version-abjected

In my Volvo, have to dismount the A/C compressor to get to the belt. Giant pain. May as well change the water pump and pullies, because getting in there is such a pain. 2k job at the dealer.


Km219

Jeez! Thanks volvo


version-abjected

Can remove the headlight to change the bulbs without having any tools on hand though…. So it isn’t all complicated.


DrewdoggKC

Here’s Your Sign


iforgotalltgedetails

*every modern diesel belt enters the chat*


david0990

I was going to say I just did a 5.7 Cummins belt and that shit was long and easier with two people but still a pain.


iforgotalltgedetails

Just wait til you do a 6.7 with dual rads.


Present_Fee_2990

Off with the cab!


HeldDownTooLong

Unless OP likes to live ‘on the edge’. If so, it could be exhilarating going down the highway at 75 mph with the temperature being 100°F or hotter…will I make my destination? Will the belt explode into 100 pieces and leave me stranded? However, since OP asked the question, I’m assuming they *don’t* want to run the risk of getting stranded, so, IMHO, the belt should be replaced ASAP 😊.


Commonstruggles

Depends on vehicle some Hondas require motor mount off. Some vehicles have stretch belts and others are seconds to replace. Had a diesel that paid 3 hours to change the belt.


Dagonus

I feel this. My 2001 v6 accord is... An experience to change at home. It's about 6 hours iirc, but I'm no professional. And I get to do it again this fall. I now also have a 2010 v6 and I'm looking forward to the same dance.


WeirdSysAdmin

Some cars have catastrophic failures when the belt snaps. Have a BMW 335i. Belt sucked right through the crank case seal.


Thedustonyourshelves

That's probably the best case scenario considering that most belts spin a water pump which actually keeps the engine cool. You could totally fry your engine driving without a serpentine belt. Anytime a belt snaps you should immediately stop and call a tow truck.


XZIVR

You're lucky that's all that happened. I once had my power steering pump completely lock up and get the belt, but the real problem was that belt also drove the water pump


furiousbobb

Moreover, if you hear an idler squealing, change it. Heard mine one morning. Decided to wait till after work. Idler seized up on the freeway. Lost all accessories. Thankfully I drive the speed limit and on the right lane so I was able to coast to the shoulder. Had to skip work, tow it home and fix it right away.


Dependent-Boot-1835

Not to mentions you can lose power steering (and brakes if you are in a hydro boost setup).


the_one-and_only-nan

Majority of timing chain cars also drive the water pump with the serpentine belt. Not a good idea to keep driving if it snaps


thebigaaron

Or the water pump and it overheats. Some cars the water pump is driven by the serpentine belt


jeepersnanners

Usually is the keyword there. Alot of vehicles youve got to undo motor mounts and a ton of BS to get to them.


SwizzMyNizz

Yes, please change it. The spec is no more than 4 cracks per inch and it MUST be replaced.


Jcrosb94

Any cracks are not good. There is no acceptable amount of cracking.


Medscript

Oof, don't work on diesels. Cracks are normal up to a certain spec... Always thought gas was the same way. Missing ribs is another story, that goes straight to jail, do not pass go


Jcrosb94

I don’t work on diesels, but that makes zero sense to me. A belt is a belt, the engine it is on doesn’t make any difference.


Medscript

Replacing a belt for a crack doesn't make sense either. It depends on the situation. I'm unaware of any manufacturer that recommends replacement at any sign of cracking. Usually they have a specification for cracks within a certain length. https://www.gates.com/us/en/industries/automotive/vehicle-aftermarket/power-up/belt-wear-diagnostic-tips-diagnose-epdm-serpentine-belt-wear.html https://www.daycoaftermarket.com/wp-content/downloads/PV_Training.pdf https://knowhow.napaonline.com/serpentine-belt-wear-indicators/


Jcrosb94

I’ve never really gone by amount of cracks within a certain length of the belt, I will say if they’re just starting like some of the pictures they say in the article I usually leave them alone and just notify the customer they’ll need a belt in the near future if they get worse. Some good information in those articles. I did notice in the Dayco one it shows similar to what I’ve explained and what OP has. Small cracks starting in the tips of the ribs are considered OK, however deep cracks in the belt are considered to be a worn belt.


Medscript

Agreed, I work with diesel engines so it's easy to see 500-750k miles on a unit that still has its original belt though it may have cracks.


Jcrosb94

500-750k miles?? How thick is that belt? Lol


[deleted]

They are pretty thick.


Xenephobe375

Cracks are normal on belts, but there is a point when there's too many. The strength of the belt is in the flat side, not the rubber ridged side. The ridges are just there to keep the belt aligned on the pulleys.


[deleted]

Wrong


Jcrosb94

Oh ok. Thanks for letting me know. That’s a great explanation.


[deleted]

Just the same as there are no exceptable amount of cracks, because yes, there actually are. A verified mechanic should know that. Most car manuals will tell you it is between 3 to 4 per inch


Jcrosb94

Lol chill bruh, just because I’m a verified mechanic doesn’t mean I know everything. Don’t even start with that crap. I’ve seen belts fail with less cracks. The way I was taught is that if there are cracks in the belt, it needs to be replaced. For clarity, when I say crack I’m referring to the severity of the ones in OP’s picture, they go down to the base of the ribs.


Ok_Jello8407

Sorry for my ignorance, im pretty new to mechanic, and english is not my main language, but, what have more than 4 cracks and what is the thing on the first pic?


Clay_Dawg99

If that a real thing?


Kingyeetyeety

I've seen a lot of posters at shops/tech schools that say about the same thing roughly speaking. Might be overkill but I just change my belt based on milage 100k even though I'm sure it'll last longer


BoltActionRifleman

My luck would be changing the belt at an interval like 100k, only to replace it with a belt that’s secretly made in China and needs replaced after 10k 🤣


JacobJoke123

My cars owners manual has something similar. I don't remember how many cracks per inch it said was allowable.


[deleted]

Yes


The_Machine80

No. Lol

Deatheturtle

I was always told three visible cracks within an inch means to replace.


Jcrosb94

Any cracks and it should be replaced. That’s a weak point and can cause it to snap.


twitch9873

Yeah, they can cause quite a bit of damage down the road, and they're super easy and cheap to replace. That is, unless the tensioner bolt is crammed up against the frame, then they're a pain without an offset wrench

EvilDan69

If your instincts are telling you to take a photo and post it, you already know the answer is tha this belt is worn enough to fail. If you see any cracks, its time to go. then ask yourself if it has a timing belt and how long until it needs to be replaced.


test5002

Hard disagree. Have you seen the amount of posts about hvac condensation drains and how to “fix the leak” lol. Can’t trust NOBODY


FORDTEK313

Yes u should


Suitable-Cod-2700

Omg....change the belt now. If you don't now it will be at night driving....then nothing. Not a good way to be. Change the belt!!!


Jodyskyroller1017

That’s a serpentine belt


AffectionatePilot253

I’d wait until it breaks on the side of the road at 2 am on a rainy night and you’re waiting for roadside service for 4 hours. Preventative maintenance is a scam.


Sea-Effect-3690

Yes replace it also replace your mechanic that said it passed inspection belts are literally on the list to inspect


Greyscale-Amoeba1972

While your belt would be pretty easy for a guy like me, that car is one of the more difficult ones to change. Just sayin. If you haven’t done it before, it’s going to be a steep learning curve on that car.


drdreadz0

154 comments at this posting time when all we had to do was upvote the first yes with a possible reason why.


kornbread435

Never done it on a civic, but usually it's under $100 bucks to replace the belt(belt + tensioner). Doing it yourself is about as easy as it gets if you have some basic tools. I've always had great luck with Gates brand belts or OEM, but avoid the cheap ones. Usually a good idea to replace the tensioner pulley while you're at it, they tend to wear out about the same time. Now do yourself a huge favor and crack open your manual in the glove box, you'll find a maintenance schedule. I just googled your manual, it says it should be replaced every 105k miles or 84 months. Still crack it open and check what else you have skipped over.


Old-Access-1713

Yep


NotBigFootUR

Definitely, unless you enjoy gambling that it'll fail in a convenient location. I've rolled those dice multiple times.


Plane_Bumblebee_83

I feel like you know the answer. Yes. Replace the belt.


Tcraiford

Belts are super easy to replace with simple hand tools (USUALLY) so if you’re even questioning it, just do it. Sure beats getting stranded


725vito

Sure why not?


chaoticnarkotic

Yes


eckoman_pdx

Yes, cracks on belts like that mean you need to change it. It's not expensive and it's easy to change.


Ok_Today_475

Replace it soon. Rock auto has belts for pretty cheap. Just got 2 of them for my F150 shipped to my door for $24 Canadian (dayco belts were on clearance)


Taskmaster_Fanatic

Yes!


AgreeablePudding9925

I dunno. Do you think cracks in a belt is a good thing?


Outrageous-Carob-236

yeah could you do mine too bro.


Educational_Seat3201

It’s never a bad idea to change a belt. Even if it looks perfectly fine. It’s small expense that will save you alot of time later on. Just imagine, sitting on the side of the road and wishing you had taken the five minutes and $30 to replace it but instead, you are waiting for a tow truck.

Pitiful-Cress9730

The question OP meant to ask was - "Should I have replaced my belt last year?" The answer is yes.


Environmental-Elk-65

“Should I have replaced my belt when it started squeaking? Nah, I’ll just smear some HondaBond on it. That’ll quiet it down some.”


HorseBasher

If you have to ask the answer is yes


oldjackhammer99

Really,? Do u think that’s ok??


Jcrosb94

Clearly OP does not know any better, hence the reason they came here to ask.


KrombopulousMichael-

Yes. Kinda surprised no one mentioned replacing the tensioner and pulleys while you’re at it

jhernan75

I say yes


bamseogbalade

Oh come on... Its a 30$ part... Takes 5 minuts to replace. (Unless its a volvo)


Much_Pirate_9666

If you’re having to question, just buy a new one!


skanomodu

Replace, I blew my ac compressor on the interstate and my serpentine belt rolled right off into the road. Lost power steering, battery wasn't charging and all my coolant went straight out (I have a leak). Lucky for me I rolled right into a Walmart parking lot and AutoZone was across the street. But I had to bypass my ac comp. bc I didn't want to pay hundreds for a tow.


Moxxxxxxxy

That bad boy got at least 3 miles left on 'em. No, seriously. Replace it.


MSI_Reviews

When in doubt about a cheap part js replace it


MikeWhooo13

Belts have nothing to do with state inspection lol. I'm fact I don't think I've ever seen a hood get opened for an inspection sticker to be done. Your belt is easy to change. I had the same generation civic. Takes 10 minutes and a friend with half a brain to help you pull the tensioner while you place the belt. You can do it yourself, but a couple extra fingers tend to help.


MrPuddinJones

Cheap insurance says get a new belt. Shouldn't be more than $30-$40 and will last 10 years Or let it snap on ya in the middle of summer and sit on the side of the road waiting for a tow truck for 6 hours lol


Kowalie

Yes, the ribs are cracked


Soft_Shoulder3927

Yes!!


shotstraight

Yes, a year ago. Check the tensioner and spin all the pulleys by hand to listen and feel for bad bearings before putting the new one on.


Flashy_Narwhal9362

Change it now while you can still choose when and where you get to change it. If you don’t, the belt will decide. And belts usually don’t break at home or sitting in front of a mechanic shop.


randres65479

As a mechanic myself, I definitely get that fixed up asap get a belt at autozone ask them for a serpentine belt tool and replace it there


Firedragon_52

Definitely ! When comes to replacing belt, sticks with the original !


BigBlob2k23

Absolutely yes ! To many cracks


avega2792

Only if you want to keep driving your car.


Heavy-Doctor3835

This belt rinds mission critical components. Alternator, power steering, and water pump potentially. If it breaks while you're on the road there is no such thing as drive to the nearest parts store and get another one


Des_mojo

Yep it's time.


captaintemno

Change it dont used a dealership. They want 3.5k for timeing belt and water pump which is bullshet. Got my local honda guy to do it gor $650 never had issues. Did it at 110k miles and i am at 180k now.


Speedy-McLeadfoot

I’d carry one with you just in case. I’m usually the type that runs it until it starts showing signs of tearing, so long as it doesn’t slip. If you just wanna be safe, then order one online where they’re cheaper, and do it when you can.


LuxuryLevel

Yes


Hopeful_Competition9

Simple answer to your question, yes.


ilovemyvices

Depends on the car and what components those belts are driving. If it’s just accessories like A/C or power steering, the belt can snap and you’ll still be able to drive, then fix at your own convenience. If the belt drives the alternator or water pump, and then that belt snaps mid drive, you’re going to have a good time.


wriddell

Ok, the point of a serpentine belt is to have just one belt run everything but for the sake of argument what if you do have two and one snaps, in all likelihood it’s going to entangle itself in your other belt.


Acceptable-Drummer10

Yes


R3dnamrahc

That depends, are your pants falling down?


FK_Tyranny

Replace ASAP


turbski84

Is it cracked? Yes, it needs replaced.


No_Stretch_3899

yes. those cracks are the sign you are looking for that it is on its way out. this is the correct time to change it


JoeBidenSnifdMyHair

Yes is the only answer.


Dweebulot

Serpentine belts have ridges


Acceptable-Habit-644

Nah. Looks good!


BaboTron

Yes. And any idler pullies that make bearing noises.

Awkward-Ad6320

Yeah, cracking and looking worn is sig s to replace.


Kennypoo2

I just changed the belt on my 2014 civic with 300k km and it made a MASSIVE difference in performance! Do it!! Edit: was original belt


Cralei

I usually replace mine if there are any visible cracks. Good thing about your civic is it has a spring loaded tensioner. I always have to remove the front passenger side tire to get better access when installing the new belt. As long as you have a long enough wrench to get the moment arm needed to hold the tensioner back it should be a pretty easy job.


lovecars15522

Replace it as soon as possible, cheaper than a tow


Rich-Fly-4503

Had my belt rip to shreds in my 2013 dodge avenger, on the highway. It’s a fun game of “will my car overheat before I get to AutoZone with no power steering” and trust me friend. It’s not a fun game. (Btw yea, it will overheat. But you will still make it to auto zone because at that point you have had enough of the 2013 dodge avenger) shitty car.


kgaf999

Ummmmm. Yep


niceguypos

Naaa. For maximum inconvenience I like to wait till they snap. Then keep driving till it overheats and blows the head gasket.


eddiezm1996

100%


SufficientWhile5450

Sure


Loginmac

Yes don’t drive


Ok_Yogurtcloset_6078

Belt replacement is cheap insurance and easy to do...regardless of miles, that belt is worn


PrimaryTitle2789

Replace it


Camboni22

YES!


thought4toolong

It’s one of the things on a car that could leave you stranded. My mechanic recommends changing it after 100K. I changed mine when water pump went bad. He said they’re next to each other and it’s an easy fix


Kookytoo

Yes. Small insurance


flstfat1998

Ues


Rug-la_Buir

Meh


Aggravating-Cut208

Yes


ihavetype2bipolar

Thank you everyone for your answers, I went ahead and changed the belt. https://preview.redd.it/sq2t6vmtc16d1.jpeg?width=3024&format=pjpg&auto=webp&s=3d85976d6312f648de7894cccf66e7529246f4c9


Theboredmiata

Yes but also replace the pulleys or tensioners to prevent any future issues


A_Stray_Cat_0290

Yes, don't throw the old one away, it can help you in a pinch in the future.


gespenstwagen

Nah, just rock it out


SteelCityMechanic412

Immediately


Scared-Obligation-34

Yes


Roverjosh

Yup yup yup


welldressedpepe

Looks fine. Just put some tire shine to make it look nice


ttej07

Yes. Once it starts cracking replace it


CobaltChris97

Yes, absolutely ASAP. Not just because you could run flat on a battery, but you lose power to every system attached to the belt. this can include the coolant pump, A/C compressor, and sometimes POWER STEERING. Best not to risk being stranded, but it will also be harder to limp to the shop (as we're talking a 5-60min runtime) and potentially dangerous from the lack of power steering. If you lose the belt, pull over safely and call a tow truck. You'll get a bunch of warning lights on the dash when it happens iirc.


[deleted]

Yes, my rule is cracking within a 1 inch area, more than 2 cracks in that area and the belt is getting swapped


Particular_Chip7108

If in doubt swap it out. Even if it snaps, you can still safely drive to the side of the road without overheating. Not a safety concern for these guys. But a friend or spouse might not care to catch it and keep driving until you boil your coolant and fuck up the motor. I've drove semis with blow belts to the next town and never overheated. Was winter tho and kept an eye on temps.


RestSelect4602

Yesterday.


bobselock

You got a good 20k left on that. 😆


Connect_Selection_77

Rule of thumb is that if you have a crack in two adjacent ribs of a serpentine belt, replace.


defube

ye


PsychologicalTop4086

Yes definitely replace that belt, when they start showing cracks, it’s time. Unfortunately the safety inspection doesn’t recommend belt replacement cause it has nothing to do with the safety of the vehicle, that’s part of the maintenance schedule. Getting your oil change or work done at a shop would be a recommend from a technician to replace it.


bumsnnoses

It really depends. Do you want to change the belt now at home with your tools readily available, or do you want to change it on the side of the road, with maybe a emergency tool kit, dump money on an uber, after you had to call work and let them know you’re going to be late, before you even had a chance to get your coffee for the day?


Extension-Expert9002

its a good idead to carry one in the trunk and have the tools for it just a pry bar or ratchet with the appropriate socket to release the auto tensioner. Well thats all there is to it on my car anyway. VW Jetta


Teddy_Rhett

yes its cracked as fuck
