Question type: Maintenance & Repair

2004 Grand Cherokee limited edition ran hot during an ice storm. We thought
antifreeze was enough but after it ran hot we found ice in the radiator lines.
After it thawed it would not crank. Could it have jumped timing and warped the
heads?

Would not crank...you mean it would not turn over or it would not start when cranking.

Hard to say without more testing and possibly removing the heads. Dry all your electrical connections off if coolant sprayed over the engine bay. Most probably the reason you can't start it. Add the proper coolant to water ratio, 50/50 and change the oil and hope for the best.
