Caravan/Voyager :: 1997 - Thumping Noise From The Engine Compartment
Aug 29, 2012
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.

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?

I start my van and open the hood to check Coolant and I notice gas spilling out engine and running down the side close to my power steering pump. So I stop the vehicle and notice gas sprayed on different parts by the back spark plugs and a little area by sensor.

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 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 have a 97 voyager. recently the airbag light has been coming on then off. now it is on all the time. In addition to the air bag light being on the horn and the steering wheel cruse control does not work. The fuses and relays are all good. I was wondering if the clock spring is the problem?

I was riding down the interstate this morning and had my cruise control set at 70mph. all of a sudden the cruise just turn off. I went to hit the gas pedal and there was nothing. No check engine light or anything, no spit, no sputter. I pulled off the side of the interstate and attempted to start the van. the engine turns over fine, but no start. all lights, radio work fine. car has fuel. it did not run hot.

I have a 2005 dodge caravan and today after taking my kids kids to school, I noticed white smoke coming from the hood of the engine. I managed to get home and check it out. With further inspection, smelled like some type of fluid is burning off I can't tell if it's oil or anti freeze. There seems to be some type of condensation in the inside of my van on the passenger windshield. I looked to check to see any leaks inside on the floor mat and underneath the van itself and nothing. What seems to be the issue?

My transmission is slipping when the engine is cold. Fluid levels seem fine. I do have a fluid leak that I monitor and add fluid when needed. It's an 05 touring with 167k miles.

I have a 1998 Caravan and the engine cooling fans wont go on. Ive replaced the relay and the temp sensor. When I pull the connector off the temp sensor the fans go on so I know the fans and fuses are fine. For some reason it seems the computer module isnt sending a signal to the relay to turn the fan on. I get the trouble codes P1491(radiator fan relay circuit fault) and P0118(engine coolant temp circuit high input).
I am also having a problem with the air conditioning not working. When I do the self diagnostic test on the A/C the results are that it fails the cool-down test. Why the computer module isn't sending a signal to the relay? Could the A/C problem be causing the cooling fans not to come on?

I have to over rev the engine to get the van to move. After that the tranny seems to work fine. Tranny fluid level is OK, and it does not smell burnt. After I over rev the engine to get moving, the engine revs seem to get back into sync for the speed I'm doing - usually just as the van starts moving, the over-revving is no longer there. Do I need to adjust the bands??

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 did a tune up on my 3.3L Dodge Grand Caravan only to find the engine is vibrating heavily. This tune up included a new coil pack, plugs and wires.
I did happen to notice a separate thing when looking at the Crankshaft Pulley that it seemed to be wobbling while the engine was running.

I have a 99' GC and just changed out the EGR valve. Now the engine cuts out when you brake or get to a low speed. Idles a little rough also.

Working on a 2001 caravan. Been sitting for about 6 months with no battery installed. decided to work on it. Got a new battery, and when I connected it the alarm went off. I dont have panic button for it so I unhooked the bat.
I think I hooked the bat back up with the thicker gray key in the ignition. I think that is the key with the chip.
The alarm did not sound but the engine will not crank, seems like it it in some security mode blocking start up. I tried cycling the key in the driver door but that did not work.

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?
