Radiator Assembly

The first step to replace the Radiator (LL8) requires draining coolant from the Radiator while also recovering the refrigerant. Lift the automobile after which you should remove any existing lower Radiator support shield. Use hose clamp pliers (J 38185) to move the outlet Radiator Hose clamp and disconnect the hose from the Radiator. First remove the inlet Radiator Hose clamps and hoses from the Radiator and then disconnect the transmission cooler lines from their position. The work starts by lowering the vehicle before taking out the cooling fan and shroud and the Radiator support diagonal brace and coolant recovery line connected to the Radiator. The worker must disconnect side panels from the shroud before removing the Radiator and all bolts securing the condenser to the Radiator. The first step for installation requires the condenser to be attached to the Radiator while installing appropriate fasteners at their designated locations and torquing bolts up to 28 nm (21 ft. Lbs.). Position the Radiator and cooling fan together with the shroud followed by a vehicle lift. Secure the outlet Radiator Hose to the Radiator while you reposition its clamp by using hose clamp pliers (J 38185). The transmission cooling lines must be connected to the Radiator followed by installation of the lower Radiator support shield when present then vehicle lowering before attaching the coolant recovery hose to the Radiator and Radiator support diagonal brace for cooling system filling.

Service and repair of radiators must start through safety measures that forbid using water on hot radiators since this can lead to dangerous steam burns. The radiator fins require protection since they ensure heat transfer operations therefore maintain them free from brushes. A compressed airflow system should be used to clean all debris from the engine side of the radiator including bugs and leaves and dirt and other particles. A mixture of warm water with gentle detergent can be necessary to clean affected areas when specific circumstances arise. The cleaning process should include the A/C condenser fins along with the area between the A/C condenser and radiator and the radiator cooling fins. It is necessary to correct any damaged cooling fins because they impact optimal performance.

One must commence Radiator (LL8) replacement by draining Radiator coolant while recovering refrigerant. The first step is to raise the vehicle while also dropping the lower Radiator support shield when available. Position the outlet hose clamp at a different spot using hose clamp pliers (J 38185) followed by hose removal from the Radiator. Start by unfastening transmission cooler lines from the Radiator before lowering down the vehicle. Proceed with the work order by removing first the cooling fan then the shroud and finally the Radiator support diagonal brace before pulling out the coolant recovery line from the Radiator. Depart the shroud from the Radiator side panels before taking out the Radiator and securing bolts that fasten the condenser to it. Start installation by connecting the condenser to the Radiator then fasten the bolts until they reach 28 n.m (21 lb ft). The vehicle should be elevated once again after attaching the Radiator to its position with the cooling fan and shroud. Position the outlet Radiator Hose on the Radiator then use hose clamp pliers (J 38185) to tighten the clamp. The Radiator transmission cooler lines should be connected while installing the lower Radiator support shield on vehicles which have it and then lowering the vehicle down followed by attaching coolant recovery hoses to the Radiator framework and Radiator support diagonal brace. The cooling system needs to undergo a final filling to perform the procedure.

The first step when replacing the body vin type 3 (GMT 360) Radiator involves draining the coolant from the Radiator while recovering refrigerant. Before proceeding with the Radiator replacement start by lifting the vehicle so you can uninstall the lower Radiator support shield when it is present. Use hose clamp pliers (J 38185) to shift the outlet Radiator Hose clamp after which you can remove the outlet hose from its location on the Radiator. The next step requires you to disconnect both transmission cooler lines before lowering the vehicle down. Start the repair by removing the cooling fan and shroud elements and continuing with removal of the Radiator support diagonal brace then the coolant recovery line. Remove the Radiator by disconnecting its side panels from the shroud before removing both components and their retaining bolts to the condenser. Installation starts by attaching the condenser to the Radiator while installing its bolts before tightening them to 28 nm (21 ft. Lbs.). Installation involves placing the Radiator followed by inserting the cooling fan together with the shroud. Raising the vehicle enables the installation of the outlet Radiator Hose while hose clamp pliers (J 38185) help reposition the outlet Radiator Hose clamp before connecting transmission cooler lines. Follow this procedure: first lower the vehicle then install the coolant recovery hose and the Radiator diagonal brace and the lower Radiator support shield before filling the cooling system.

Install the outlet radiator hose to the radiator, reposition the outlet radiator hose clamp using Hose Clamp Pliers (J 38185), and connect the transmission cooler lines.

Remove the cooling fan and shroud, followed by the air inlet grille, and then detach the coolant recovery line from the radiator.

Remove the upper radiator to condenser bolts and the coolant recovery line from the radiator, then lift the condenser to detach it from the radiator retaining tab and remove the radiator.

Begin by draining the coolant from the radiator and recovering the refrigerant.

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

Lower the vehicle and reposition the inlet radiator hose clamp using the Hose Clamp Pliers (J 38185), then remove the inlet radiator hose.

Install the radiator and then the cooling fan and shroud.
