Jeep Grand Cherokee WK2 3.0 D: Tips for Water Pump Replacement
2014 Jeep Grand Cherokee WK2, 3-liter diesel.
The water pump is leaking, and the antifreeze is leaking. We'll need to replace the water pump. Please note that not all the rubber rings on the aluminum water pump intake manifold are included with the pump. They absolutely must be replaced. They've lost their elasticity from constant heat. They crack and burst when removed. One ring is number 68147586AA. Another rubber ring is number 5066884AA – it's installed on the mating part of the intake manifold, which is attached to the cylinder head.
