I have an 2000 3.3L Dodge Grand Caravan. It has a coolant leak. The amount of coolant leaking fluctuates. Some mornings its a small puddle the sizes of a grapefruit and other times its just a drop or two. The dealer did a coolant pressure test found the leak is at the timing cover. They wanted $1000 to fix it and a balked. Does anyone have a procedure on how to fix this myself? Is this covered on a Haynes or Chilton book?

My 1998 Dodge Caravan is leaking coolant from the timing cover. Is the repair accomplished by replacing the o-rings and gaskets on the timing cover? On another thread I see people talking about replacing the timing cover itself at a cost of $700. What can you tell me?
you'll need a special puller a lot of patience and mechanical aptitude. you'll need to remove the oil pan, remove the oil pump pickup tube, etc. the oil pump is contained in the timing cover so you need to be very careful on this repair so you don't do more harm than good.
