The replacement procedure of inlet radiator hoses on 4.8l, 5.3l, and 6.0l engines begins with draining the cooling system. Begin by unfastening clamp connections of the air cleaner outlet duct to both
Throttle Body and maf-iat sensor before removing the air cleaner outlet duct. Several steps might require removing the engine sight shield. Alongside the task of radiator inlet hose removal), one should first detach the radiator vent inlet hose from its clips and position the inlet hose clamp to the radiator before removing the hose from the radiator. First detach the inlet hose clip securing the
Fan Shroud before relocating the inlet hose clamp to the water outlet. This allows removal of the inlet hose from the water outlet. Attach the inlet hose to the water outlet while placing the inlet hose clamp in its proper position. After installing the inlet hose clip to the Fan Shroud proceed with connecting the inlet hose to the radiator while repositioning the inlet hose clamp. The radiator vent inlet hose must be reattached to radiator inlet hose clips but an engine sight shield only needs installation if required. Install the air cleaner outlet duct only after confirming the arrow points towards the Throttle Body attaching stud. Tighten both air cleaner outlet duct clamps to 7 nm (62 inch lbs.) at their positions on the Throttle Body and maf-iat sensor. Complete this work by filling the cooling system.
