hankfan79 Posted May 27, 2013 Report Share Posted May 27, 2013 Mechman, First off let me say I have spoken to Josh on a couple of occasions. Very respectful and helpful. I also received your product in record time so big thumbs up to that! Just recently installed your 240A alternator on my 2012 Toyota Camry. Since installation I have what seems to be a "chirping" sound when running. Have you ever heard of such a noise? Can you explain what it might be? I replaced the belt with a 1/2 inch smaller as recommended by Josh. A 1 inch smaller belt was too small. The noise is in the engine bay not through the speakers. Any help would be appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
SnowDrifter Posted May 27, 2013 Report Share Posted May 27, 2013 Sounds like belt slip. Does it do it all the time or only when the car is cold/hot?

kickass audio Posted May 27, 2013 Report Share Posted May 27, 2013 Try seeing if it is belt slip. If you have an automatic tensioner the whole idea of getting a shorter belt is erroneous to fixing belt slip as the tensioner has the same amount of tension regardless on its position. To see if your tensioner is bad get some water and a spray bottle. Spray the water on the flat side of the belt and see if it goes away. If it does then your belt is not under enough tension and a new tensioner is needed. If you have a manual tensioner such as ones where you have to usually turn a bolt on the alternator to move it up and down you need to tighten it so your belt has less slack. If you find that spraying the back of the belt with water you still have squealing then you probably have a belt alignment issue. Check that all your ribbed pulleys such as the one on your alternator are in line with the ribbed pulley of your crank shaft. If they are out of alignment it will cause belt squeal. If that is not the case then the final thing is you have a bad bearing. Take the belt out and wiggle each pulley side to side and up and down. If it has play then that pulley is bad and needs to be replaced. Sometimes cars with idler pulleys such as my envoy the idler pulleys go to shit rather fast. Lmk if you need anymore help!!

hankfan79 Posted May 27, 2013 Author Report Share Posted May 27, 2013 Car has less than 5k miles. All factory pulleys are good. Might need to be shimmed or something. 1/2 smaller fit but 1 inch DID NOT. Might need a custom 3/4 inch smaller. Quote Link to comment Share on other sites More sharing options...
kickass audio Posted May 27, 2013 Report Share Posted May 27, 2013 Just check what I said with the water. You would be surprised how much that helped me out with my belt slip issue. I kept tossing money toward shitty advance auto belts that are super inferior and getting tensioners and idler pulleys until I figured out my belt slip issue. What I use now is an advance auto tensioner and idler pulley and then I have a Carquest Gates belt for it. The gates belt made all the difference. I noticed the one from advance had always slipped and would wear the paint off my idler pulley in 3 months and at that point my belt drive would squeal whenever my engine was cold.

kickass audio Posted May 27, 2013 Report Share Posted May 27, 2013 Im sure they will still say it is belt slip. That is their most common problem they encounter and is not at all their fault. Seriously water is your friend with this. as long as you dont shove a power washer or hose in your engine then you will be fine. Just a few sprays on the back of the belt a few times to see if it goes away or not. Simple as that.

hankfan79 Posted May 27, 2013 Author Report Share Posted May 27, 2013 Alignment..yes. That's what I was thinking. This would require shimming. Quote Link to comment Share on other sites More sharing options...
Lyferxb9s Posted May 27, 2013 Report Share Posted May 27, 2013 my wife's truck did the same thing no matter what tensioner we installed. finally got sick of it and took it to a shop, they installed a Goodyear gator back belt, 25k Mike's without a sound.

MECHMAN Posted May 28, 2013 Report Share Posted May 28, 2013 As stated before chirps are usually a misalignment. I check the pulley alignment as the video states Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
