Question about 1997 Dodge Caravan

1997 Dodge Caravan A/C pump vibrates = very noisey

My Caravan A/C pump has been vibrating for some time now, I have tightened the bolt which attaches it to the engine block, but then today I looked for the noise problem and the bolt was sitting there just lose. After investigating, I saw that the bolt was broken.
Now I do not know if this bolt screws into the engine block or not as the pump support bracket has threads in it, hum.

Can someone please help me with this, do I need to remove a broken bolt or what.
I am sick of Dodge problems.

    Thanks shanat,

    I looked at the issue last night, found out that the bolt closest to the front of the van, of the mounting bracket has been sheard off. Plus the mounting bracket at the engine block is broken. Now I have to replace the mounting bracket plus try to remove the originally noticed broken stud.

    What a rotten mess!

    If I have to change the A/C pump, can it be done without losing the oil material in there?

    And if I do lose the oil, will that wreck the pump?

    Or, is there a diagram that I could download to see what is all the parts in that mess?

    Any way,

    Thanks for the help, it was useful

As long as the support bracket is tight it should be fine to leave and just make sure that the compressor is bolted to the bracket tight also should be fine

Dodge caravan engine noise

It's hard to come up with a solution for this one without actually "feeling" the symptoms. I assume that what you're describing is that you can feel vibration coming from the engine. I suggest that you have the engine mounts checked.

Also, make sure the mount that sits just behind the radiator has rubber in the middle of it where the bolt goes through. On some models, the rubber mount is attached to the frame (which attaches to a bracket on the engine). On other models, the rubber part is attached to the engine (which attaches to a bracket on the frame).

I've seen cases where the mechanic had a bracket on the engine and another bracket on the frame. Instead of the mechanic removing one of the brackets and replacing it with the rubber mount, they would just align the two brackets together and run the bolt through them.

This causes the vibration to be transferred directly from the engine to the frame. This will also put stress on the exhaust pipe causing it to eventually break because the engine is not seated properly. The engine will be tilted slightly to the rear...

If your mechanic is a good mechanic you should be able to take it back into that mechanic and have them recheck their work at no additional cost. There are many bolts holding on the: Power Steering Pump, Alternator, Water Pump, Belt Tensioner, Crankshaft Pulley and Idle Pulley. Many of these have to be removed inorder to replace the Timing Chain Cover Gasket. It they were not tightened down correctly, this could be the vibration you are describing. Also the Front (right side) Motor Mount had to be loosened to gain access. If this was not tightened down correctly, it could cause vibration.
The Power Steering Pump itself not only has mounting bolts, but also the retaining bolts on the pulley. Again if these were not tightened down correctly, it could cause the pulley to vibrate.
Talk to the mechanic (again if you have to) and work it out with them. Most good mechanic will help you.
But to answer your question directly: Yes there is a very good possibility that this has something to do with the Timing Gasket Cover Gasket work.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at

Vibration when steering

Hi. I would Check the lower ball joints on the front-end. You will find that they could be loose and the cause of your vibration problem. I would also Check the U-joints as you may have one that is worn and gets out of alignment while coasting. also, a bad or malfunctioning power steering pump can also cause this type of disruption as well but, its quite noticeable because of the whining sound it will imitate. you will find the problem in one or both of the areas discussed.

Please rate and god bless.
