The Radiator outlet hose replacement procedure must start with draining the cooling system by utilizing cooling system draining and filling (Static Fill) (GE 47716). The first step in Radiator outlet hose replacement requires air cleaner assembly removal. The Radiator inlet hose requires disconnection from the Radiator through j 38185 hose clamp pliers while using these tools on the Radiator inlet hose clamp at the Radiator for tension disengagement. For both sides of the engine proceed with this process until you remove the Radiator inlet hose. Proceed by taking off the remote Power Steering Reservoir. Disengage tension on the Radiator outlet hose clamp at the Water Pump by using j 38185 hose clamp pliers before disconnecting the hose from the Water Pump. After supporting the vehicle under its weight disengage clamp tension from the Radiator outlet hose at the Radiator before disconnecting this hose from the appliance. Remove the Radiator outlet hose. Alignment of reference marks between hoses and Radiator throughout installation will help protect the connection points from strain. Spray clean coolant inside the new hose diameters so you can put the hose into place. The Radiator outlet hose requires attachment to the Radiator followed by initial clamp tension. Put the vehicle in a lowered position to join the Radiator outlet hose with the Water Pump while tightening the clamp securement. Install the remote Power Steering Reservoir before executing the Radiator hose installation by fitting the hose between engine and Radiator regions with j 38185 to activate clamps. The cooling system requires static fill (GE 47716) before putting on its air cleaner assembly.

Repeat the process by using the Hose Clamp Pliers (J 38185) to disengage tension on the radiator inlet hose clamp and disconnect the hose from the engine.

Lubricate the inside diameters of the new hose with clean coolant before installing it.

Ensure that the reference marks on the hoses and the radiator are aligned to prevent strain on the radiator fitting, which could lead to cracking or breaking.

Install the radiator outlet hose and connect it to the radiator, engaging tension on the clamp at the radiator, then lower the vehicle and connect the hose to the water pump, engaging tension on the clamp there as well.

Reinstall the air cleaner assembly and fill the cooling system using the Cooling System Draining and Filling (Static Fill) (GE 47716).

Repeat the process by using the Hose Clamp Pliers (J 38185) to disengage tension on the clamp and disconnect the hose from the engine.
