I have 168k on my 07 V6. I had a leak from the water bypass hose behind the thermostat. I replaced that and the upper radiator hose. A few days after that repair, my garage floor was covered in coolant. Turned out to be the water pump leaking. I would probably go ahead and replace it.
Changed the oil in the diffs and transfer case. Thought the oil from the rear smelled a bit burnt. I took a whiff from the new bottle to compare, and nope that's just what gear oil smells like :barf:
