Default timing cover coolant leak - how hard to fix?

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?

Thanks
-Bob

Default 3.3 timing cover coolant leak

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.

Now on the 3.3 motors. You may need to buy the updated timing cover assy. It does come with a new water pump and oil pump assy already on the cover.

Gee..... pictures would be so good, found I have a leak on my 2000 3.3 Grand Caravan as well. Pretty certain I can tackle it; but pictures really help!

Is AllData mainly a professional Mechanic shop kind of service?

Thanks
