'01 Caravan SE whining noise

[Kalidor]

Hello and good morning!

Now I've searched this forum about the problem I am experiencing and I am not sure that any of the posts I read really apply. So please excuse me if I am posting about something that has already been answered.

This Caravan has 68k miles and up until recently the whining noise I hear only happened when cold starting the car on a cold day. Just yesterday it also started to make some kind of a rattling sound in addition.

The original whining noise lasts only for a few seconds when cold starting, the new rattling sound also only happens when cold starting but lasts quite a bit longer (about 20 seconds). Can any of you advise me on what is going on with my vehicle?

Sounds like the auto tensioner or an idler roller that's balking when cold. Get a piece of garden hose, hold one end to your ear and move the other end around the tensioner and the idler rollers when you start cold in the morning. Works just like a stethescope and will help identify the culprit.

Thanks for that hint. I tried what you suggested just now and it seems to come from the left side (standing in front of the car). I have to admit, I do not know enough about engines to figure out what it is.

I am just trying to get an idea so I don't get pulled over the table once I bring it in to get this fixed.

Check to see if it comes from the very back. That is where the alternator/generator is.
