My fiance bought a 2002 3.7 liberty 4 months ago with 96,000 miles on it from a wrecking service. Someone had the jeep towed in and repaired by a mechanic there and couldn't pay for it so he put it on craigslist.A month ago, a pin hole developed in the radiator on the plastic end towards the battery. While replacing the radiator, I noticed rust or something similar all through the cooling system. I flushed it out the best I could, and added distilled water to the new mix. Well, the other night after a huge storm we got gas.About 1/3 a mile after driving away the jeep started missing for a few seconds and then quit running.She tried to restart it but it wouldnt start, barely even tried to start.As I was looking around under the hood, I noticed the upper radiator hose wasn't pressurized, but the coolant tank definetely was .Then her father came and had her keep trying to start it, and something kinda banged inside the motor, sounded like the top half of the motor to me.Now it won't turn over at all by the starter or by the crank pulley with a breaker bar. I fear it's a skunked motor, or possibly hydro-locked(i hope) .If it is blew up, does jasper sell re-mans or who would be better?
