I have an 02 Caravan with a 3.3L engine and 130,000 KM's. My problem is that when I start the van from cold it will start, rev up, but after a few seconds when the rpm's come down to about 1000 there is a clunking noise that happens. The van runs good after the noise and I do not notice anything else wrong with it. It seems like it maybe something around the serpentine belt but I am not sure. I replaced the serpentine be the other day and it is still happening. After the initial start of the day it will not do it again until it is left for a long period. I can not pin point where this is coming from but it is starting to worry me.
