The procedure for Radiator inlet hose replacement on llv and llr vehicles with engines of 2.9l or 3.7l starts with draining engine coolant. Starting with hose clamp pliers (J 38185) users need to shift the inlet Radiator Hose clamp towards the Radiator and remove the hose from the Radiator. Again use hose clamp pliers (J 38185) to move the inlet Radiator Hose clamp out of the engine way before you remove the hose from its engine position. First step for installation requires attaching the inlet Radiator Hose to the engine afterward using hose clamp pliers (J 38185) to reposition the inlet Radiator Hose clamp to the engine. Install the inlet Radiator Hose on the Radiator before securing it with hose clamp pliers (J 38185) to put the clamp on the Radiator. Finally, fill the cooling system.

Driving coolant from the system needs to be completed beforehand when replacing a radiator outlet hose on llv and llr models with 2.9l and 3.7l engines. Positioning the outlet Radiator Hose clamp with hose clamp pliers (J 38185) away from the Thermostat housing enables removal of the outlet Radiator Hose that connects to the Thermostat. Raising the vehicle enables hose clamp pliers (J 38185) to relocate the outlet Radiator Hose clamp properly before removing the hose from the radiator surface. Place the outlet Radiator Hose to the radiator before securing it with hose clamp pliers (J 38185) to reposition the outlet Radiator Hose clamp properly on the radiator. Lower the vehicle and install the outlet Radiator Hose to the Thermostat while using hose clamp pliers (J 38185). Afterward reposition the outlet Radiator Hose clamp to the Thermostat housing with the same pliers. Finally, fill the cooling system.

Engine coolant drainage is essential before starting to replace the radiator inlet hose for vehicles with LLV - 2.9L and LLR - 3.7L engines. After using Hose Clamp Pliers (J 38185) to shift the inlet radiator hose clamp away from both radiator and engine components separate the hose from the radiator. Position the inlet radiator hose clamp away from the radiator with Hose Clamp Pliers (J 38185) to allow removal of the hose from the engine. To install the inlet radiator hose begin by placing it onto the engine after that use Hose Clamp Pliers (J 38185) to position the inlet radiator hose clamp correctly on the engine. Reposition the inlet radiator hose clamp to the radiator by using Hose Clamp Pliers (J 38185). Finally, fill the cooling system.

Engine coolant draining is the first task before changing the Radiator inlet hose on llv and llr models with 2.9l and 3.7l engines. You should utilize hose clamp pliers (J 38185) to shift the inlet Radiator Hose clamp so it moves away from the Radiator before uninstalling the hose from its position on the Radiator. With hose clamp pliers (J 38185) the user should move the inlet Radiator Hose clamp away from the engine to remove the hose from its position. The inlet Radiator Hose installation begins with attachment to the engine while hose clamp pliers (J 38185) move the inlet Radiator Hose clamp toward the engine. Place the inlet Radiator Hose to the Radiator before securing it with hose clamp pliers (J 38185) while moving the hose clamp towards the Radiator. Finally, fill the cooling system.

Reattach the radiator vent inlet hose to the radiator and fill the cooling system using the designated filling method.

Fill the cooling system.

Use the Hose Clamp Pliers (J 38185) to reposition the outlet radiator hose clamp away from the radiator, then remove the outlet radiator hose from the radiator.

Attach the radiator vent inlet hose to the coolant recovery reservoir and secure it with the retaining clips.

Connect the radiator vent inlet hose to the coolant recovery reservoir and secure it with the retaining clips.

Remove the vent inlet hose from the radiator and take off the retaining clips from the radiator vent inlet hose.

Reposition the outlet radiator hose clamp to the thermostat housing with Hose Clamp Pliers (J 38185) and fill the cooling system.

Detach the radiator vent inlet hose from the coolant recovery reservoir.
