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.
This is from Alldata although the pictures don't come through using copy and paste.

Be sure mating surfaces of chain case cover and cylinder block are clean and free from burrs. Crankshaft oil seal must be removed to insure correct oil pump engagement. NOTE: DO NOT USE SEALER ON COVER GASKET
Position new gasket on timing cover (Fig. 154). Adhere new gasket to chain case cover, making sure that the lower edge of the gasket is flush to 0.5 mm (0.020 inch) passed the lower edge of the cover.
Rotate crankshaft so that the oil pump drive flats are in the vertical position.
Position oil pump inner rotor so the mating flats are in the same position as the crankshaft drive flats (Fig. 154). CAUTION: Make sure the oil pump Is engaged on the crankshaft correctly or severe damage may result.
Install timing cover (Fig. 154).

Install crankshaft front oil seal.
Install water pump and pulley.
Install crankshaft vibration damper.
Install engine mount bracket (Fig. 152) and tighten M10 to 54 Nm (40 ft. lbs.) , M8 bolt to 28 Nm (21 ft. lbs.) .
Install idler pulley on engine mount bracket (Fig. 152).
Install right side engine mount.
Install camshaft sensor.
Connect the heater return hose at rear of timing chain cover (Fig. 150) or at water pump inlet tube (if engine oil cooler equipped) (Fig. 151).
Connect the radiator lower hose.
Install A/C compressor.
Install accessory drive belt.
Install oil pump pick-up tube with new O-ring. Tighten attaching bolt to 28 Nm (250 in. lbs.) .
Install oil pan.
Install inner splash shield and right front wheel.
Fill crankcase with engine oil to proper level.
Fill cooling system.
Connect negative cable to battery.
will get any stubborn gasket off. take care not to gouge the sealing surfaces
and before you mount new gaskets or any sealants cleanm sea;ing surfaces again surface with some acetone or laquer thinner (will ensure a good adhesion)
also while your in there you may want to do the waterpump(although its not hard job to do so I myself wouldn't do do it, cuz im cheap lol)
