MY 05 WK started leaking coolent & was found to be from a crack in the timing chain cover (where the water pump is attached to). the PN is :- 53021227AA.
My question is, can a unit bought from a 3.7 engine work? reason i ask is, so far ebay has turned up used units, but its for the 3.7.
i recall reading that the 3.7 & 4.7 are essentially the same engine with less cylinders. if so, will the timing case fit?
please help me out guys. it hurts to see the jeep in this state.
