Upper Hose

The Radiator Hose replacement process starts with draining the coolant then removing the air cleaner part. The hose clamp pliers (J 38185) can be used to free tension on the radiator inlet hose clamp on the radiator before removing the hose from the radiator. The hose clamp pliers (J 38185) should be used to release tension from the hose at the engine before disconnecting. First disconnect the radiator inlet hose along with the remote Power Steering Reservoir. You must first elevate and stabilize the vehicle while using hose clamp pliers (J 38185) to loosen the radiator outlet hose clamp on the Water Pump surface before removing both clamp and hose connection from the Water Pump. Unclip the radiator outlet hose clamp at the radiator with the hose clamp pliers (J 38185) before unhooking the hose from the radiator during removal. To prevent damage during installation position the reference marks on hoses and radiator to match one another before tightening fittings. Clean coolant approved should be applied to the inside hose diameters before setting up the radiator outlet hose on the radiator. After engaging tension on the radiator outlet hose clamp at the radiator the vehicle needs to be lowered to attach the radiator outlet hose to the Water Pump while holding tension on that clamp as well. The remote steering reservoir receives replacement while the radiator inlet hose connects to the engine from its original position through the hose clamp pliers (J 38185). Resistance on the radiator inlet hose clamp can be achieved using the hose clamp pliers (J 38185), after which you should reconnect the hose to the radiator. Reinstall the air cleaner assembly followed by filling the cooling system.

Connect the radiator inlet hose to the radiator and engage tension on the radiator inlet hose clamp at the radiator using the Hose Clamp Pliers (J 38185).

First, drain the cooling system using the Cooling System Draining and Filling (Static Fill) (GE 47716).

Next, remove the air cleaner assembly.

Use the Hose Clamp Pliers (J 38185) to disengage tension on the radiator inlet hose clamp at the radiator, then disconnect the radiator inlet hose.

Use the Hose Clamp Pliers (J 38185) to disengage tension on the radiator inlet hose clamp at the radiator, then disconnect the radiator inlet hose from the radiator.

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.
