Weird noise after timing belt replacement

Some movements are normal because it is mounted in rubber. However, rattling isn't. If you feel that is where the noise is coming from, then it certainly is a possibility.

Do you plan to replace it yourself or have the dealer do it again?

Let me know what I can do to help.

Take care,

Joe

I may go out there tomorrow and just re-tighten all the bolts on the motor mount just to be sure the dealer didn't miss something when doing the timing belt.

I would try to replace it myself for sure, it's a $25.00 to $30.00 part. But before I do anything I want to listen with the stethoscope again just to be double sure before buying anything. That's the only thing we didn't do today was stethoscope.

Hi,

That is a good idea. Let me know if it is the problem. Also, I attached the directions specific to this vehicle for replacing the front engine mount.

Let me know what you find or if I can help.

Take care,

Joe

I finally managed to get a video of the chattering. I had to drive it for a while with the AC going, then stop and out the parking brake on (but leave it in drive). If I put it in park or turn off the AC, the chattering stops.

Hi,

It sounds like the tensioner is chattering, which is very possible, or the A/C clutch is kicking on and off.

I attached a pic below. The highlighted part is the belt tensioner. Check to see if that is vibrating when this is happening.

Next, in red, I circled the A/C compressor. At the front of the pulley is the clutch. With the A/C off, the pulley spins freely. When you turn the A/C on, the clutch clicks in and turns the compressor. Check to see if that clitch is kicking on and off. Here is how you can tell:

The center of the pulley will not be turning with the AC off. When it's on, the center will engage and turn. If you look at pic 2, in red I circled the clutch. With the AC off, that will not turn while the pulley does. When turned on, that engages and begins to turn with the pulley.

Let me know what you find or if you have other questions. Also, if I had to guess, I would say the tensioner is the issue and not the compressor clutch, but since it stops when turned off, that is where the sound may be coming from as well.

Take care,

Joe

Can I just replace the idler and tensioner pulleys, or do I need to replace the entire assembly? I saw where they sell the individual pulleys for way cheaper than the assembly.

Hi,

Each of the pullies has a bearing. If the bearing was bad, yes you could do that. However, I'm questioning if it is the tensioner itself. It could also be caused if one of the other belt-driven accessories is faulty.

What to do is remove the belt and spin all the belt-driven accessories to make sure none are tight or make noise. Also, take note if there is any play up/down, side to side, in and out on the pullies.

If everything seems good, then suspect the pulley assembly needs to be replaced. Take a look at Rockauto. Com for pricing. Usually, they offer the best price.

Let me know if I can help.

Take care,

Joe

Yes, I plan this weekend to relieve the tensioner and check all the items it connects to. I've already been looking at RockAuto the prices range from $50.00 to $150.00+. What's the difference?

Hi,

Often times the brand is causing the cost difference. As long as it is for your vehicle, you shouldn't have any trouble. If you find something inline by a private seller that is nameless, be careful. There have been a lot of after-market parts that last a day if you're lucky. LOL

Let me know what you find or if you have questions.

Take care,

Joe

Okay, we've definitely narrowed it down to the tensioner. I've noticed it even chatters a bit when the A/C is off and I'm turning hard or even right when I press the gas to take off. Sounds like any extra load on the tensioner causes chatter. And if you pull on the belt slightly you can hear the spring inside click.

Hi,

If you hear a clicking, that does sound like the issue. Have you replaced it yet?

Let me know.

No, I haven't ordered the part yet. How much longer do you think it will last, considering how it's sounding in the video I posted earlier?

Hi,

That's a really hard question to answer. It could last another 6 months or 6 minutes. LOL However, the belt will likely start squealing prior to total failure. Pay attention to that.

Let me know how things turn out for you.

Take care,

Joe

Hi,

That's usually the least expensive place to get them. Also, when checking out it will ask where you learned about them. Use this code and you'll get another 5% off.

Question. I've noticed that the belt is riding off center on the tensioner pulley. It's not coming off, but it's like 1mm close to the edge facing the wheel. Will this cause any issues? My neighbor who used to be a mechanic said the belt said as long as it's on the pulley it's fine.

Hi,

He is correct, but I would rather know it's centered. Do me a favor. Just keep an eye on it to see if it changes at all.

Let me know if there is anything I can do to help. Also, if you want to take a pic of how it is and upload it for me to see, I would be happy to let you know my thoughts.

Take care,

Joe

I haven't noticed it move at all. I think it's just that we barely got the belt on there due to the new tensioner being so tight and hard to move. We figured it would self-center but I guess not. I might try to relieve the tension and slide the belt over some more of I can.
