Caravan/Voyager :: Intermittent Rumble At Idle - Noise From Alternator
Aug 5, 2015
2007 Grand Caravan 3.8L 100K mi. New noise chirp-chirp-chirp Sometimes an intermittent rumble at idle seems to be in synch with the serpentine belt especially when the A/C is engaged. I changed the serpentine belt which did not look bad and did not emit the noise. Noise seems strongest at the alternator when I use a stethescope. I noticed the pulley seems a little loose with the belt removed, but the bolt is tight. This alternator has an overrunning alternator decoupler (OAD) pulley so maybe the loosness is normal. The bearings seem smooth when I spin it with the belt off, and it charges fine. Just the noise is bothersome. Do I need to change out the alternator or just the OAD pulley?

I'm also having battery drain issues also an had alternator an battery tested, ok. Is this click from relay draining battery and what relay could it be? I switched them an had same click .

I have an engine noise on my 2000 Dodge Caravan with the 3.3 engine. It sounds a lot like the grinding of a rotating part. It occurs at start up, momentarily, then goes away. If I drop it in gear and start doing low speed maneuvering in the driveway, it comes back. If I turn on the AC it comes back. In all cases, the noise goes away at around 1200 rpm.
The noise occurs again, when I shut the engine down.The engine performs and runs smooth and normal otherwise. No stalling, stumbling, or bad gas mileage to report.
I can "feel" the noise with my hand, when I put my hand on the ac compressor bracket, or the intake manifold, or the valve cover. I've tried the listening through the stick method, and it seems to be coming from the front area of the engine. But I can't be sure. It is something internal. Let me describe:
I thought it was my AC compressor or clutch going bad. The fact that my AC had stopped working well, and was making jet engine noises at high rpm supported me decide this. I replaced the compressor. The AC works great now, and the jet engine noises went away. But the grinding noise is still there. As described.
I wishfully thought it was the belt tensioner or idler pulley. I replaced both of those. Noise still was there. I pulled off the serpentine belt, and started the engine. It made the noise, very briefly as it started, then went away completely. It made the noise again briefly as I shut the motor off. So it's still there without any of the accessories turning.
The noise is loud and obnoxious at idle when under load. It just can't be good. I've read theories about similar sounding problems, saying they could be loose timing chain, bad oil pump, slapping pistons, crank journals, flexplate/flywheels cracked.
I'm going to try doing an oil system flush, and then I'll change it out with a little thicker oil. See if that makes any difference in the noise. Currently I'm running 5w-30 Mobile 1. I think. I'll let you know if it changes anything. I'm also thinking I want to make a short video of the car idling and making the noise for my video camera. I'll post that on youtube and link it here.

I recently acquired a 04 grand caravan with 130k on it today i got off freeway and was sitting at light and i felt a pretty significant intermittent miss so i had it scanned and came back with those 2 codes and a previous evap code in wich i was aware of. Im gonna change plugs and wires in a.m. and possibly run sea foam threw brake booster vacuum. If there's something elese i should look at for those codes p0300 & p0302! I tried to clear codes and cel stayed on didn't go off and come back on it stayed illuminated??

Our 2007 Grand Caravan with a 3.3 Liter Engine has intermittent vibration which feels similar to driving over rumble bars. It usually occurs between 30-50 mph but sometimes at 70-80 mph as well. Have had the suspension checked and had outer tie rod end replaced. Also had sway bar bushings replaced and front end aligned. We then brought it to transmission shop and had a transmission diagnostic performed. They found no faults with the transmission and thought the engine needed a tune-up which we did with no success. At a recent oil change, we asked for them to test drive it and check again for any suspension problems. They did not notice any vibration during the test drive and found no problems with the suspension.

I have an 02 Dodge Caravan 3.3 L Flex . It had initially stalled and wouldn't start. Check engine light was on. Had it towed to a Cert Mech. He said it needed a "Major" tune-up. I let him do this. It included: New Coilpak, plugs, plug wires, cam-sensor, crank sensor. That's what was on 1st invoice.
It started, but was still running very rough. He then recommend a new PCM. After choking on his estimate, and paying the initial invoice, I decided to let someone else have at it. Mech # 2 installed a "Rebuilt" PCM, New Battery, and a PCV Valve.
It runs good now BUT, ...It has this weird idle Misfire. The only time it happens is at a stop light when at idle. And it doesnt do it all the time. This check engine light is not on... At this point, all I want to do is sell it.I have over 1K in repair costs and still can't get rid of this misfire.

I took the van on a road trip and the engine seems like it wants to stall at lights. the idle stays at 500 rpm or so most of the time while at stops. there appears to be no way to adjust the idle and there is no Czech injun light on.. what could the problem be? the engine is a 3.8l

My check engine light came on today and while driving, the idle (RPM's) were very high. At about 80KMs, it was about 3500 and when I accelerated, the engine would race along with the RPMs. While stopped, idling seems fine. I couldn't get over 80KMs/Hr without the idle going too high.
What it could be? Haven't had time to check codes as it is long weekend and garages are now closed till tuesday.

Dealer replaced rack,twice. Still thumping,they installed new struts and 4 sway bar links and bushings same thump still there. I unhooked swap bar links and tied them to brake line and backed it out is my shop and thump is still there and sounds like both sides. This van has 56,000 miles on it and the ball joints and control arms feel and look tight. Is there anything about how frame mounts that might cause this?

We have a 2012 Dodge Grand Caravan and has a whistling noise when starting up? We are in Wisconsin and its damn cold. It only does it when its cold out. Once the engine warms up it goes away. But my wife is freaking out about it. I am thinking it might be something with the air intake but not sure.

I have a 1997 Voyager that I am having a thumping noise that is coming from a black module that is mounted in the engine compartment over the passenger side fenderwell. It has 2 vacuum lines and an electrical connection coming off of it, one of the vacuum lines has a tag on it that says EVAP. The engine seems to be running fine, although every now and then it seems like it might idle a bit rough, and there are no CEL on or codes in the computer. Don't know what is this module called.

I changed my cabin filter on my 2013 Dodge Grand Caravan and now there is a humming noise when AC or Fan is turned on. The noise increases and decreases with fan speed. I tried putting the old cabin filter back in to see if the new one was loose or defective, but the humming noise was still there. I also made sure airflow arrow was pointing downward. Could it be that a leaf or something fell off of the filter and is now in the blower. How do I check the blower?

I am experiencing an annoying noise from the front struts when passing over bumps. I do not believe that the front end is bottoming, but it seems to give a deep thud sound. It is not a tin sound, but more like something loose and insulated. What is a jounce bushing? Are these something in the strut assembly and susceptible to getting loose? I have read about the springs could be the culprit, but could it be that the front spring is bottoming and the strut is hitting a bottoming rubber ? Jounce bushing?

Back in June I replaced all 4 brakes and rotors. Now all of sudden I hear a loud grinding noise in the front end only when I'm braking to a complete stop.
I took all 4 tires off and then took off the pads. The pads and rotors are all still brand new and have very minor normal wear. Also the calipers still look good.
I then put everything back together and went for a test drive. The grinding noise is still there. It's very loud and only when I come to a complete stop.

this has been an outstanding van, quite reliable. it has about 115,000 miles on it. Recently, I've noticed that the transmission makes a 'tapping' noise when it shifts or downshifts. every gear has that same slight 'tap'. the tranny shifts fine, smooth, but this sound worries me a bit. any chance this could be a u-joint issue?

I have a 01 1.8T and I'm looking for a little more rumble and idle noise currently my set up is a 3 inch downpipe cat less and a resanator delete into a stock muffler with modified tips, I had the downturn cut out and ran it straight out the back. Anyways my question is what muffler would you recommend that gives a nice idle and aggressive acceleration with my current set up ( the 3 inch downpipe and res delete).

We just purchased a 2012 Grand Caravan and was wondering where to get a key and program it. I know the key will be an arm and a leg if i get it from the dealer. Is there a tutorial that tells how to program it as well?
