I Found The Problem With The C5

Love your videos great recommendation on the wires love them

[@georgesontag2192]

Check the underside of the thermostat housing for leaks, it runs down and drips over the pump housing and it looks like the pump seal, when it's really the thermostat.

[@ernestbrodie6601]

Maybe you should invest in a stethoscope to help isolate various sounds coming from your engine. My dad taught me to use a wood dowel and hold one end next to my ear and the other end against various parts of the engine to locate problems while the engine was running. This is how we located the strange sound coming from me 49 Chevy convertible after we replaced the engine with a rebuilt shot block. Believe it or not, it was the push rods rubbing against an old line to the valve train. An easy fix but without using the wooden dowel we would have torn the whole thing apart to find it.

[@mjphoto45]

I finally got mine back. I got the summit HB. Love it

[@richardelliott8352]

this comment is about a year late, but I am glad you found an alternator that worked. It used to be very difficult to find a part the C5 computer understood , that was why the original French part is so expensive. A typical replacement part would work only until it threw a voltage the computer didn't understand , then you got sent directly were back to go. One of the reasons a lot of guys bought a model specific rebuild kit and rebuilt the part rather than try to find a working replacement. Your cars appetite for batteries might be a short, or related to someone in the past installing a part that the fitment books at the parts store says works, but really doesn't in application.

[@rab2826]

Chris,. I think for $80 or not much more you could have a new one from Rockauto. Probably looking on KZbin to see how to fix it. Try Rockauto for the water pump also.

[@mycorvettelife]

I get almost everything from Rock Auto. The alternator was out of stock at the time.

[@tedmcconaughey8438]

Check the tensioner on the belt for the ac compressor...they have a high failure rate..will make that chirping sound right before the bearing fails...

[@mycorvettelife]

I took that belt off a long time ago to eliminate that possibility.

[@rickfidler7884]

Make sure all accessories are off each shutdown....if it dies put a kicker on battery for ten minutes before putting a maintainer to recharge overnight...works great...had the same problem...the default kept showing on the maintainer

[@gopro2027]

I replaced my oem alternator in december with that oreilly's alternator. Lemme just tell you about my experience... Cold starts cause error code charge system fault when cold started in cold weather. I live in missouri and get that message nearly every morning on around or below freezing temps. Now that it is spring i'm not getting it anywhere near as often though. I heard from the forums this was caused by some electronics that are in the oem alternator but not in these oreilly's alternators for whatever reason. Voltage regulator I think they said? I'm not too sure. Second thing, I just had to get it replaced 2 days ago. The one I bought in december started making a horrible noise (not belt chirp/slip, it was some sort of internal failure) in mid february. So after about 2 months of use it had issues basically. They did warranty it for me but honestly they kind of tried to get me to not to and tried to blame it on my belt tension. Anyways, here's to hoping our new alternators last long!

[@mycorvettelife]

Lovely....

[@alancameron2433]

[@donlovelace2127]

Use battery tender, Problem Solved

[@glennwhitmire5556]

It looks like its coming out of the weep hole on the bottom of the water pump. Its on the housing of the shaft, on the underside. Also, do you have a keyless entry alarm with a passive system on it. Those will drain your battery if its not a daily driver, since they are always scanning for the FOB.

[@rtracing59scott30]

I had the same chirping problem but no coolant leak. The AC belt tensioner was bad. Quite now. Hope this helps you.

[@Jdikmen]

Similar story here with alternator - only my 2001 is an A4 with the decoupler pulley. I have had nothing but Hell trying to find a compatible/reliable alternator for the past 12 years. Have purchased 6 in all from $125 rebuilt to $700 high performance - only a couple were compatible with the PCM. Last summer I caved to the suggestions on a Corvette Forum insisting that my best bet was to find a local shop to rebuild my original Valeo. Old guy, over 40 years experience, two day turnaround. Multiple phone calls over 4 months! Finally went down to pick it up and he handed me a box full of parts (about half my alternator) and simply said "it was burnt up". Currently running a new AC.Delco with occasional Charge System Fault.

[@TeyvatHistoria]

Hey Chris. I had a similar mind numbing troubleshooting issue with my belts chirping on my C5 FRC in 2019. The problem began within a few weeks of replacing a bad water pump with a Autozone Duralast water pump. I replaced the belt, the pulley, the tensioner, checked the alternator no squeaks there. After months of trying and failing to figure out what was causing the chirping I discovered a tiny amount of water was leaking down from the where the main hose connected to the water pump. I cleaned up the belts to eliminate the coolant and the chirping stopped! So I figured ok it’s the leak for sure... but ofc since it was still leaking the squeak would come back pretty quick. I replaced the hose thinking since the pump was only a few months old at this point that the pump had to be fine... replaced all the hoses intact with a nice silicone set while I was at it..... continued to leak from the same spot. A couple days later the real culprit revealed itself. The actual hose spout that the hose slides over was not properly pressed into the pump and had become lose allowing a tiny amount of water to seep out of the spout seam. Found this out the hard way, driving the car on the interstate the spout ejected itself from the pump and dumped all coolant out of the car basically instantly. Thankfully I reacted quickly got off the road, and shut it down with no permanent damage. Replaced the pump with an AC Delco on Amazon, the leak, the chirp both gone ever since. Nearly 2 years now.

[@davidleon1299]

Have you tried using a mechanics stethoscope to diagnose the squealing noise coming from that c-5 ? I had a problem like that on two of my cars it turned out to be the small idler pulley which had the wrong style grease installed from the factory. One made the noise in extreme cold and yes you guessed it the other one once it ran and got hot enough. Hope this helps....

[@harveytaylor7189]

Check your harmonic balancer,if it wabbles it can cause chirping.shine a flash light while running engine to see. I replaced mine and it solved problem

[@daleschmitt2919]

[@jackthompson6192]

That vett sounds great,, keep up the good work and videos..

[@theflying70]

I rebuilt alternators for (coincidentally) 40 years professionally. That squeak you heard is inconsequential; it's just the sound of the used (but not necessarily worn out) brushes riding on the slip rings. If you had spun the old alternator up in the vice with a gun you would have not heard this noise. Almost any used alternator will make this sound when spun by hand and is not a warning of impending doom.

[@coreyware8037]

It’s definitely your water pump. I had a similar issue happen with my C4. Also, I think the reason you’ve gone through so many batteries is because you live in Arizona. Heat is bad on car batteries. I live in Texas and they don’t last long here either. Maintenance free batteries are really low quality now. They all leak, even when they’re new.

[@mycorvettelife]

Typically a batter will at least last 3 years in AZ. The Vette is garaged 99% of the time too so it doesn’t see as much heat.

[@idessaoutlaw]

If you don't own it it won't chirp 🥃😎

[@RedCat2299]

Summit Racing SUM-C2501. SFI rated to 12,500 RPM. $220. Looks like you got a stock balancer which needs to be upgraded. The balancer I recommended is stock size but far superior to stock.

[@TorquilMcLeod]

It's hard to find good info on battery issues with Corvettes because you'll get all the "Corvettes kill batteries" tropes. I see you park it on a battery maintainer so presuming it's working correctly my guess is the alternator. I think the voltage regulator is in the alternator so once replaced so once replaced you'll know the alternator and voltage regulator should be good. A maintainer is good because it keep the battery charged, but it can paper over a problem with the charging system or a parasitic loss. Try connecting a multimeter to see if you're getting 13.8-14.4 volts at idle. Also try connecting a multimeter between the negative battery terminal and negative battery cable and the car to see how much current is drawn when the car is off. If you're not familiar with testing current, use the 10A shunt on the meter. Once connected it will take a few minutes for the car to turn off. My 2005 draws about 4 A for lime 5 mins, then goes down to around 1.5 A and then finally after about 15-20 minutes (seems crazy long but apparently that's normal) it goes down to 60 mA. The forums say it should be closer to 30 A but I've parked the car for over 3 weeks not on the maintainer and it was fine. How hot does your garage get in the summer? Heat kills batteries so you could be replacing it every 2-3 years.

[@rklessars0763]

I definitely feel you man, I've gotten a check engine light on my O2 sensors, I replaced them already, but I ended up getting the light again for the downstream ones I was confused but I just figure I'd order new ones, I did just that, and I installed them thinking that finally my light would go away, nope, I ended up buying new ones again and nop the light came back on, I still have the light on, but I'll definitely buy more pricey ones on autozone, hopefully they work man, we all go through the struggle😅

Yep you need a battery disconnect , can get at AutoZone for about 20.00 , yep water pump and that’s what causing the serpentine belt to make noise, I have a feeling your buying after market parts for your car bad idea , parts that are important like water pump , alternator , any emissions parts yes including. Cats , get from dealer put on yourself or your mechanic you trust , It will be cheaper in the long run if you intend to keep the car . Over time you would see I’m correct but do what you want it’s your car but to save money listen , I know from experience Great video Chris as usually

The water pump on the car is OEM, as is every pulley on the motor, so your point is not taken.

I wouldn't use a battery disconnect on a modern street car, that's winga dinga hot rod stuff and could cause more issues with powering up and and down the electronics. Use a battery maintainer when parked for more than a few days which I see you're already doing.

[@1wtrahan]

[@TorquilMcLeod]

@@1wtrahan Sounds like you have a great car and that's good the battery disconnect has been worked well for you. A disconnect also doesn't do anything to reduce battery sulfation or discharge from sitting. After about 3 month of sitting even disconnected a lead acid battery will be discharged, so if it does have enough charge to start the car, that's a heavier load on the alternator which it isn't designed to do, and a harder charge on the battery which can reduce its life.

[@Morenitto89]

My C5 starts as if it doesnt want to start. Im also getting a message every now and then about low charging.

[@carmenpete]

on my C5 I was told these cars love to eat batteries, the corvette wrench near me always use Interstate batteries and if the car sits for more than a week, battery tender is a must. on another note, the same guy told me the car stumbling when wet, throwing a p1460 (IIRC) was due to my battery being too weak so a couple hundred dollars later and still no change :(

[@echadmiyodea]

Please take a look at some youtube vids about "planned obsolescence", and you'll come to realize why those re-man parts like water pumps and alternators generally only last one or two years. All they have to do with the water pump is allow the bearings to be exposed to the coolant, which is easy for them to do. With alternators it is generally the internal voltage regulators that start getting flakey or failing. The regulators used to be a separate device that could be replaced for $15 and mounted in a cool protected place that wouldn't cool and vibrate the regulator circuit to death. They changed this design decades ago to put regulators inside the alternator. With your battery problem I would suspect the known grounding issue that all C5's have. With bad connections at body grounds, something called grounding loops will form, which can seem to randomly energize some circuits in the car, tripping relays and such, which increases the draw on the battery just sitting there parked. There are a few ways to deal with this issue, and I know buying new batteries gets old quickly. First is to simply install an on-board battery charger and plug in when the car is parked. You want a 1.5 or 2.0 amp maintainer, such as Schumacher brand that will not discharge the battery when not plugged in. Second option is to install a physical battery cut-off switch like racecars have and disconnect when parked. A third option is to address the likely cause, and fix/replace all the grounds in the car with better stuff. It may be a pain to deal with buy maybe worth it if you love the C5, and a plus is it gives you more potential content for the channel.

[@johnhickman1597]

Soap water sprayed on the belt will tell if it's the belt squeaking. A shot of wd40 into the pulley will tell if it's a bearing. There is a reason the original alternators are so expensive. It's well documented on the corvette forum. I have had a reman water pump do the same thing so you're not the only one that's had to deal with that. I switched to a fixed tensioner and gator belts a long time ago so that might be something to look into.

Go and get yourself a empty spray bottle and fill it with water and spray it on your belts with the engine running. If the squeaking goes away it is coming from your belts. I had a problem very similar on my work Van. If you find that to be your problem before you do anything else go out and get yourself a bottle of 303 Protectant. Spray that on your belts while the motor is running. It fixed my problem and didn’t hurt a thing. There is a guy on you tube who swears by the stuff. He goes under the name Sweet Project Cars. He soaks all his fan belts in 303 before he puts them on the car. Like I said it fixed my Serpentine belt squeak.

[@raykruger9989]

I had this problem with both my 87 C4 Z51 hatchback and 99 C5 convertible. I’ve gone through several alternators over the years. My local Chevy Dealer’s Service/Parts Department discovered that the last rebuilt alternator I bought from Pep Boys was the wrong type. It may have over-heated, then over-charged the Sears Diehard sealed battery that had lost too much water in the battery acid. I’m sure that it’s much more of an issue in Phoenix than here in PA.

You should maybe take the water pump off first to look at it.

Since the car is of a certain age, it is probably best to change everything on the front of the engine. Check the power steering pump pulley. Some were made of plastic and detonate under load causing catastrophic engine failure. Turn One makes a great pulley for that application. Also change the harmonic balancer. The Summit C2501 is a great alternative to the ATI. It’s warranty is also 4 times longer (1 year versus 3 months). All the best.

You need to get yourself an automotive stethoscope.

I’ve often took about a 36” plastic tube and held one end to my ear and the other end I hold in front of the individual rotating parts, ie, water pump, alternator, to try to isolate the noise. Usually works.

some use a wooden dowel, or even a long screwdriver , to lessen the chance of flexible line getting caught in moving parts , but I use a very cheap automobile stethoscope from harbor freight , bought only because it was so cheap. I have used it once, just to try it out, before any repair situation.
