[QUOTE="GP Noir, post: 447223, member: 22885"] Overheating at highway speeds usually indicates airflow is being blocked or diverted. Airflow can be blocked or diverted by anything mounted in front of the radiator such as winches, lights, grill inserts or stingers. Airflow can be blocked from exiting the engine compartment by aftermarket splash shields, incorrectly installed splash shields, skid plates or other items. Air flow through the engine compartment might be disrupted by removing or incorrectly installing shrouds. Damaged or clogged fins on the A/C condenser or transmission cooler will block airflow to the radiator. What happened when your Jeep overheated? Was it boiling over? Or just indicating high temps? Was coolant lost just from the overflow bottle? Or was coolant lost in the radiator as well? If it was just the overflow bottle, it could be the bottle was over serviced and the system was seeking its own level. [/QUOTE]
