The process of outlet Radiator hose replacement starts with draining the cooling system for 4.8l, 5.3l, and 6.0l engines. Disconnect the outlet duct clamps of the air cleaner located at the Throttle Body and maf/iat sensor. Next remove the Radiator inlet hose clip attached to the outlet duct followed by removing the air cleaner outlet duct. The outlet hose removal process starts with unfastening the clamp at the Water Pump to extract the hose from the pump and moving to the next step which uncovers the hose at the Radiator for replacement. The installation sequence requires attaching the outlet hose to the Radiator after which you should position the outlet hose clamp at the Radiator. Clean the Water Pump then install the outlet hose before positioning the outlet hose clamp at the Water Pump. Install the air cleaner outlet duct by making sure its Throttle Body end arrow points to the Throttle Body stud before proceeding. First secure the Radiator inlet hose clip onto the outlet duct. After that use a wrench to tighten the air cleaner outlet duct clamps at the Throttle Body and maf/iat sensor to 4 nm (35 inch lbs.). Finally, fill the cooling system.

Before changing the Radiator vent inlet hose, drain the cooling system. Then, take the vent inlet hose clamp off the Radiator and pull the vent inlet hose out from the Radiator. Move the vent inlet hose clamp up from the surge tank and remove the vent inlet hose from inside the surge tank. Install the hose from the vent inlet to the tank and fix the vent inlet clamp on top of the tank. Attach the hose to the Radiator after you have removed it. Then place the hose clamp over the hose's point of attachment on the Radiator. Finally, fill the cooling system.

The radiator outlet hose replacement process begins with disconnecting the maf/iat sensor assembly from its connection to the air inlet tube by unlocking the hose clamp next to unwinding the pcv hose from the air cleaner outlet duct. Users can detach the air inlet tube and resonator through a removal of the retaining wing nut followed by upward movement until the hinge clip frees itself from the Throttle Body. Drain the coolant from the system and move the radiator outlet hose clamps following their correct positions on the surge tank and Water Pump. Detach the radiator outlet hose from both surge tank and Water Pump before moving the clamp back to the radiator and finally removing the hose. Attachment of the new radiator outlet hose begins with fixing it to the radiator then placing its clamp before connecting the hose to the Water Pump and surge tank. Position all clamps properly during the process. The hinge clip should align with the Throttle Body lip while installing the air inlet tube by pushing it downward until the mounting stud enters the hole in the air inlet tube before tightening the resonator retaining wing nut. Finish the cool system filling while securely fastening each clamp of the pcv hose to the air cleaner outlet duct at 4 nm torque (35 inch lbs).

The procedure to replace the radiator outlet hose for a 4.3l engine requires starting with the detachment of the maf/iat sensor from the air inlet tube through clamp removal before eliminating the pcv hose connection from the air cleaner outlet duct. Start by removing the retaining wing nut from the assembly to pivot the air inlet tube with resonator against the Throttle Body for hinge clip release. Starting with cooling system drainage empty the fluid before moving on to relocate radiator outlet hose clamps at surge tank and Water Pump and extracting the radiator outlet hose from surge tank and Water Pump components. Afterwards position the clamp at the radiator while removing the hose from this location. The installation begins with attaching the new radiator outlet hose sequentially between the radiator and Water Pump and surge tank while readjusting all clamps. Set the hinge clip along the Throttle Body lip before you pivot down the installation of air inlet tube and resonator until the mounting stud locks into the air inlet tube hole. Fasten the resonator through the retaining wing nut while you reattach the pcv hose before putting in the maf/iat sensor assembly with the air inlet duct. Tighten its clamps to 4 nm (35 inch lbs.). Finally, fill the cooling system.

Drain all cooling fluid before you replace an outlet Radiator hose on 4.8l, 5.3l and 6.0l engine vehicles. The air cleaner outlet duct requires clamp loosening at both Throttle Body and sensor locations before removing the Radiator inlet hose clamp from the outlet duct and the air cleaner outlet duct. The outlet hose replacement process begins with loosening and removing the clamp at the Water Pump before extracting the Water Pump hose. Then continue by loosening and removing the Radiator clamp and removing the Radiator hose. To install begin with setting the outlet hose at the Radiator position before securing the outlet hose clamp at that location. Begin outlet hose installation at the Water Pump before clamping down the outlet hose at its position. The air cleaner outlet duct installation requires proper alignment of its Throttle Body end arrow toward the attaching stud followed by duct installation. Secure the Radiator inlet hose clip onto the outlet duct before tightening all air cleaner outlet duct clamps to 4 nm (35 inch lbs.) at both the Throttle Body and maf/iat sensor. Finally, fill the cooling system.

The first task to replace the radiator inlet hose for 4.8l, 5.3l, and 6.0l engines requires draining the cooling system fluids. To perform the task you should first loosen the air cleaner outlet duct clamps situated at the Throttle Body and maf/iat sensor before removing the radiator inlet hose clip from the outlet hose and the air cleaner outlet duct. Disassembling the engine sight shield lets you detach the radiator vent inlet hose from its clips on the radiator inlet hose. First shift the inlet hose clamp to the radiator before taking out the inlet hose from both the Fan Shroud and the radiator. To proceed with installation remove the inlet hose from the Water Pump while repositioning its clamp at the Water Pump. Install the inlet hose by attaching it to the Water Pump while positioning its clamp at the Water Pump. To install the inlet hose you must first position it at the radiator before installing the inlet hose clamp at the radiator location. Install the radiator vent inlet hose to the radiator inlet hose clips after reattaching the inlet hose clip on the Fan Shroud. Open the engine sight shield only if required then put it back while pointing the arrow from the air cleaner outlet duct towards the Throttle Body attaching stud before reinstalling the air cleaner outlet duct. Next install the radiator inlet hose clip onto the outlet duct while also tightening the air cleaner outlet duct clamps at the Throttle Body and maf/iat sensor to 4 nm (35 inch lbs.). Complete the procedure by filling the cooling system.

Reconnect the PCV hose to the air cleaner outlet duct and the MAF/IAT sensor assembly harness connector.

Attach the new radiator outlet hose to the radiator and reposition the clamp, then connect it to the water pump and surge tank, ensuring the clamps are properly positioned.

First, drain the cooling system.

Finally, fill the cooling system.

Remove the radiator inlet hose clip from the outlet duct and take out the air cleaner outlet duct.

Ensure to align the arrow at the throttle body end of the duct with the throttle body attaching stud before installing the air cleaner outlet duct.

Reposition the vent inlet hose clamp from the radiator and remove the vent inlet hose from the radiator.

First, drain the cooling system.

Reattach the inlet hose clip to the fan shroud and install the radiator vent inlet hose to the radiator inlet hose clips.

Install the radiator inlet hose clip to the outlet duct, tighten the air cleaner outlet duct clamps at the throttle body and MAF/IAT sensor locations, ensuring the clamp screws are tightened to 7 Nm (62 inch lbs.), and fill the cooling system.

First, drain the cooling system.

Finally, fill the cooling system.

Reposition the surge tank outlet hose clamp at the surge tank and remove the surge tank outlet hose from the surge tank.

Fill the cooling system.
