Upper Hose

In order to replace the surge tank inlet hose, you must drain out your cooling system. The iicjose cl10m pliers (J 38185) should be used to release tension to reposition the surge tank inlet hose clamp at the surge tank, then remove the surge tanker se inlet hose from the surge tank. Then, release tension and move the clamp to the Radiator and then disconnect the surge tank inlet hose from the Radiator. Take off the surge tank inlet hose assembly of the vehicle. For installing, lubricate the inside diameters of the hoses with clean coolant before hooking the surge tank inlet hose to the surge tank inlet hose tee at the proper place. Then install the surge tank inlet hose to the Radiator with a new hose clamp. Finally, fill the cooling system.

Before servicing the Coolant Reservoir for surge tank hose/pipe replacement at the inlet workers need to drain the entire cooling system first. Attach hose clamp pliers (J 38185) to release tension then reposition the surge tank inlet hose clamp positioned on the surge tank. Before you disconnect the surge tank inlet hose from the Radiator you must remove pressure from the clamp while repositioning it at both the surge tank and the Radiator. The vehicle requires removal of the surge tank inlet hose assembly. Before adding new hoses to the installation you must apply clean coolant to all inside diameters of the pipe sections. Apply the surge tank inlet hose to its designated position in the surge tank inlet hose tee before tightening a new hose clamp. Install the surge tank inlet hose by connecting it first to the Radiator before you fill the cooling system.

The first step to replace the Radiator outlet hose starts with draining the cooling system followed by removing the air cleaner assembly. The hose clamp pliers (J 38185) should be used to release the Radiator outlet hose clamp tension at the Thermostat Housing before disconnecting the hose from the housing. The hose clamp pliers (J 38185) should be used to loosen the Radiator outlet hose clamp at the Thermostat Housing then disconnect the hose from the thermostat. Next raise and support the vehicle before readjusting the clamp tension at the Radiator outlet hose on the Radiator for hose removal. Disembark the Radiator outlet hose from its location. Install the Radiator outlet hose by properly matching the reference marks on the hoses and the Radiator to avoid damaging the fitting points. Clean coolant should be applied internally to the hose diameters before positioning the Radiator outlet hose into its place. Attach the Radiator outlet hose to the Radiator before tightening its clamp at the Radiator position. Install the Radiator outlet hose to the Thermostat Housing while maintaining tension on the clamp at the Thermostat Housing. Perform a final step by installing the air cleaner assembly followed by cooling system fill-up.

First, drain the cooling system and remove the air cleaner assembly.

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