2003 Grand Cherokee 4.7L dropped off for overheating. Unusual and expensive failure. The hydra-fan has locked up and will not allow the cooling fan to turn. The hydra-fan is run by power steering fluid and the flow is controlled by the pcm to maintain correct fan speed.
2000 Jeep Cherokke is getting the rear main oil seal, front crank seal and valve cover gasket replaced today for oil leakage.
