Radiator

A partial drainage of the cooling system marks the starting point for changing the Radiator (L26). You should start by removing the condenser line to Radiator retaining bolt together with the cooling Fan Shroud assembly. With hose clamp pliers (J 38185) the worker should move the hose clamps to different positions on the Radiator outlet hose before extracting the Radiator outlet hose from the Radiator. The next step requires removal of condenser mounting bolts but extra caution must be exercised to protect both Radiator and condenser lower mounting points. High enough condenser elevation enables you to release the lower mounts from Radiator front features after which you can remove the Radiator from the vehicle. Place the Radiator within the vehicle while aligning the condenser feet with the lower mounting sections at the Radiator front. Apply only the special length bolts to secure the condenser onto Radiator end tanks because longer bolts can produce damage. You must install condenser mounting bolts according to a torque specification of 13 n.m (115 lb in). You should begin with reattaching the Radiator outlet hose to the Radiator unit followed by positioning the Radiator outlet hose clamp using hose clamp pliers (J 38185), then securing the condenser line to Radiator retaining bolt and finally installing the cooling fans before the cooling system fills.

The replacement of a Radiator (L26/3.8L) starts with draining part of the cooling system. After removing the cooling Fan Shroud assembly proceed with removing the condenser line to Radiator retaining bolt. Hose clamp pliers (J 38185) enable you to move hose clamps to the Radiator outlet hose and extract the outlet hose from the Radiator. Unscrew the condenser mounting bolts with caution as you avoid the lower connecting points of the Radiator alongside the condenser. Lift the condenser verticality to free its lower feet from critical mounting features on the front Radiator before lifting the Radiator from the vehicle. During installation simply set the Radiator inside the vehicle then direct the condenser feet to match the mounting elements. Only apply the unique bolts designed for end tanks at the condenser section when installation is complete and tighten them to 13 n.m (115 lb in). Rely on hose clamp pliers (J 38185) to repose the hose clamp before installing the Radiator outlet hose. Mount the condenser line along the Radiator retaining bolt before installing both cooling fans. Finally, fill the cooling system.

First, remove the cooling Fan Shroud assembly with j 38185 (Hose Clamp Pliers) when replacing the Radiator. Be sure to raise the Radiator up and take it out of the car. When you are putting the Radiator back in place, check that the condenser slots in properly at the front without touching or bending the lower mounting points. Only the special length bolts should be used for this step, because any longer bolts will cause damage to the Radiator end tanks. Secure the condenser with 13 nm (115 lb in) of torque, and then put the Fan Shroud assembly back in place.

Lift the radiator out of the vehicle.

Use only the special-length bolts for the condenser to avoid damaging the radiator end tanks, tightening them to 13 Nm (115 lb in).

Using Hose Clamp Pliers (J38185), reposition the hose clamps from the radiator outlet hose, then remove the radiator outlet hose from the radiator.

Lift the radiator up and out of the vehicle.
