A little update on the Jeep... Fuel pump got plugged and died, replaced that and the filter. New battery / alternator. Took it out camping for the first time, ran great on the way in and handled well off road.
On the way home though, a massive coolant leak sprung! Was hitting my fan and spraying all over the engine, dumping out what looked like a liter per second. Fortunate to make it up a hill to the closest oasis with a telephone in a no service area. Coolant finished entirely leaking out within a minute of arriving. Got a tow home and now trying to diagnose what happened...
Hoses look ok and when I put water in the radiator, leak immediately starts without running the engine. Appears to be coming out of the bottom of the water pump, so I'm guessing that is what caused the massive leak. Replacing the pump, thermostat, belts, and hoses this weekend. Wish me luck!
