sloshing sound indicates air in the system pull up on a incline and pull the radiator cap off and let it run.
the idea is the air will run to the highest point in the system.
had the same issue i back flushed the heatercore and purged of air.
Park up on oil changing ramps or on a incline pop the hood pull the radiator cap give the hoses a good squeeze and rev the motor once or twice.
This works for the 4.0L for sure
