What was happening was coolant was slowly leaking out of the weep hole on the front of the water pump, and then running along the top of the oil pan and down the back, or dripping down onto the steering linkages and running down them before dripping onto the ground. The puddles were under the axle, under the back of the oil pan, or under parts of the steering linkages. When I first noticed the small random puddles of coolant that appeared under my Jeep if it had been sitting for a while, I couldn’t figure out where it was coming from. On the front of the pump there’s a weep hole just below the input shaft, when the internal seals start to wear out, coolant will leak (or weep) out of this hole, letting you know it’s time for a new water pump. Thankfully, whoever originally designed water pumps for engines added in an early-warning feature to let you know when the pump is starting to go bad. The radiator has been replaced, the exhaust manifold cracked and was replaced, the power windows and locks are slowing, and most recently, the water pump started to die. As my faithful XJ has grown older over the years, it’s started to show signs of its age (and probably the results of all the trail use it’s seen).
