Those engines (latest Gen Hemi) are very durable and can compare to GM's LS small blocks; MO. If there are that many issues it had a hard life and abused.

It's a simple, straightforward replacement but a tight package non-the-less. Key is finding a reputable salvage yard first, then closest to you for a good solid engine as it's not something that you would want to do twice.

You'll need to remove the front bumper cover, brace which then allows access to the radiator and condenser for removal

Some yards will allow you to inspect the engine and start it if they have not removed it from the vehicle.
