For a replacement of Radiator outlet hose in 4.8l, 5.3l, and 6.0l engines, the draining of the cooling system is necessary. Disconnect the air cleaner outlet duct clamps at the Throttle Body and maf/iat sensor and then pull out the air cleaner outlet duct. Remove the outlet hose clamp from the Water Pump and take out the outlet hose from the Water Pump. Then remove outlet hose clamp from the Radiator and take the outlet hose out of the Radiator. In installation, connect the outlet hose to the Radiator, and adjust the outlet hose clamp to the Radiator. Next, attach the outlet hose to the Water Pump and reposition the outlet hose clamp back on the Water Pump on to the pump stud that is on the Throttle Body end of the duct, directing the arrow at the Throttle Body stud. Replace the air cleaner outlet duct and the Radiator inlet hose clip to the outlet duct. Lastly, secure the air cleaner outlet duct clamps at the Throttle Body and maf/iat sensor, make sure that the screws of the clamp screws are tightened to 7 nm (62 inch lbs.) and top-up the cooling system.

The first step to replace an outlet Radiator hose for 4.8l, 5.3l, and 6.0l engines is to drain the cooling system. You should begin by loosening air cleaner outlet duct clamps that attach to the Throttle Body and maf/iat sensor before removing the Radiator inlet hose clip from the outlet duct and taking out the air cleaner outlet duct. Begin by relocating the outlet hose clamp at the Water Pump before pulling off the outlet hose from the Water Pump and continuing with relocating the outlet hose clamp at the Radiator for removing the outlet hose from the Radiator. The first step for installation requires you to fit the outlet hose against the Radiator while securing the outlet hose clamp to the Radiator. The second step involves setting the outlet hose to the Water Pump before positioning the outlet hose clamp at the Water Pump. Reinsert the air cleaner outlet duct while aligning its Throttle Body end arrow with the Throttle Body attaching stud before securing the Radiator inlet hose clip on the outlet duct. Tighten all air cleaner outlet duct clamps at their positions on the Throttle Body and maf/iat sensor to 4 nm (35 inch lbs.) while filling up the cooling system.

The replacement process of 4.8l, 5.3l and 6.0l outlet Radiator hoses begins with draining the cooling system fluid. Begin by loosening the air cleaner outlet ducts at the Throttle Body which also includes the clamps of the mass airflow/intake air temperature (MAF/IAT) sensor before removing the air cleaner outlet duct. Remove the outlet hose by moving the hose clamp from the front of Water Pump before releasing the hose from the Water Pump. Proceed with moving the outlet hose clamp from the Radiator then detach the outlet hose from the Radiator next. The installation process requires a step where the outlet hose must be connected to the Radiator followed by installation of the outlet hose clamp to the Radiator. To complete installation of the outlet hose position it at the Water Pump while securing the clamp in place with attention to the Throttle Body attaching stud direction. Complete the reinstallation of air cleaner outlet duct before you fasten the Radiator inlet hose clip to the outlet duct. Screw the clamp bolts on the air cleaner outlet duct at the Throttle Body and maf/iat sensor until they reach 7 nm (62 inch lbs.). Finally, fill the cooling system.

Secondly you need to move the inlet hose clamp from its position on the Radiator before extracting the hose from the Radiator opening. You should move the inlet hose clamp from the Radiator to extract the inlet hose at the Radiator. After that remove the inlet hose from the water outlet through its clamp removal. You should begin the installation process with the inlet hose attachment to the water outlet followed by relocating the inlet hose clamp onto the water outlet. Attach the inlet hose to the Radiator and fix the inlet hose clamp against the Radiator at its spot. Finally, fill the cooling system.

The replacement procedure for outlet Radiator hose in 4.8 5.3 and 6.0l engines starts with cooling system drainage. The procedure starts by loosening air cleaner outlet duct clamps at the Throttle Body and mass airflow/intake air temperature (MAF/IAT) sensor locations before removing the Radiator inlet hose clip from the outlet duct. After that, remove the air cleaner outlet duct. The procedure begins with moving the outlet hose clamp from the Water Pump and taking out the outlet hose from the pump followed by moving the outlet hose clamp from the Radiator to extract the outlet hose from the Radiator. During installation first attach the outlet hose to the Radiator while positioning its clamp at the Radiator location and then connect the outlet hose to the Water Pump with the clamp installed at the Water Pump. Line up the arrow at the Throttle Body end of the duct with the Throttle Body attaching stud before mounting the air cleaner outlet duct. Place the Radiator inlet hose clip onto the outlet duct before you tighten both air cleaner outlet duct clamps which should be set to 7 nm (62 inch lbs.) for the Throttle Body and maf/iat sensor. Finally, fill the cooling system.

Starting the replacement of the inlet Radiator Hose requires draining the cooling system fluids. Begin by loosening the clamps that secure the air cleaner outlet ducts because they surround the Throttle Body and mass airflow/intake air temperature (MAF/IAT) sensor locations. The Radiator outlet hose requires removal of its clip before removing the air cleaner outlet duct. The engine sight shield needs removal if required. The Radiator vent inlet hose demands removal from its clips on the Radiator before securing the inlet hose clamp at the Radiator position. First cut off the inlet hose clip from the Fan Shroud before extracting the inlet hose from the Radiator followed by positioning its clamp at the Water Pump before removing the same hose from the Water Pump. To install the hose system first attach it to the Water Pump and then clamp it at the Water Pump location. Install the inlet hose at the Radiator before applying the inlet hose clamp to its position. The Radiator vent inlet hose requires installation to the Radiator inlet hose clips after securing the inlet hose clip onto the Fan Shroud. Reinstall the engine sight shield by matching the arrow at the Throttle Body end of the duct with the Throttle Body attaching stud before inserting the air cleaner outlet duct. Position the Radiator inlet hose clip onto the outlet duct after installing it to the outlet duct and secure the air cleaner outlet duct clamp screws at the Throttle Body and maf/iat sensor locations to 7 nm (62 inch lbs.) torque and fill the cooling system.

The first step before hose replacement requires draining the cooling system fluid. Detach the clamps securing the air cleaner outlet duct both at the Throttle Body and maf/iat sensor and then take out the duct. The engine sight shield should be removed if necessary. First detach the radiator vent inlet hose from its clips securing it to the radiator before moving the inlet hose clamp to the radiator and removing the hose from the radiator's port. Before continuing move the inlet hose clamp off the Fan Shroud and the inlet hose from the water outlet while removing the inlet hose clip from the Fan Shroud. The installation process begins with attaching the inlet hose to the water outlet while repositioning its clamp. First secure the inlet hose clip to the Fan Shroud while you attach the inlet hose to the radiator and finally tighten the inlet hose clamp.
