For the last four months I've had a real problem with a metallic clunk in the drivers side engine bay on my 91 Caravan. I though for a while it may have been the transmission self destructing. However, no problems ever ensued. I replaced the transmission mount and the clunk went away...
I was ecstatic, until I had to brake quickly, and the clunk came back. It's been driving me mad for a while. It came and went with acceleration and braking.
Then the daughter's 91 Caravan went down with brake problems... so she's driving mine. I get a call last night that she drove to where she's dog-sitting with
- the battery light on,
- it was over heating and
- there was no power steering.
Yep, you all guessed it, the Caravan threw the serpentine belt.
This morning I replaced the belt and found the alternator was loose and the serpentine belt would have had a slight wobble. I suspect that was the reason it threw the belt.
Then my daughter said: "Dad, while I was looking at the car, before I called you, look what I found..." And she handed me a hammer! I asked her where she found the hammer. She pointed to above the Air filter assembly, in front of the driver's side shock tower. I don't remember laying it there, but I'm sure I did. I've been in and out of that engine bay several times and never noticed it. To be fair... it's a grease stained wooden handled hammer that kind of blends in with the rest of the engine bay.
She found the clunk... I drove it 45 miles today without a clunk... the silence was heavenly.
Moral of the story: Account for your tools, one way or the other.
