Radiator

Engine coolant drain should be the first step for Radiator replacement followed by the removal of upper Radiator seal and upper tie bar. The hose clamp pliers (J 38185) enables the disconnection of the coolant overflow hose from the Radiator while sealing it with a plug. You should disconnect the Radiator hoses using the hose clamp pliers (J 38185) from both upper and lower ends while placing them properly to the side. Disconnect the lower tie bar bolt that holds the transaxle oil cooler pipe bracket then extract the cooling fans. Use the cooler quick connect tool (J 41623-B) to disconnect the upper and lower transaxle oil cooler pipes from the Radiator after sliding off their plastic caps from quick connect fittings. You must disconnect the condenser bolts from the a/c condenser then remove the condenser from the Radiator to raise the Radiator out of the vehicle. A special bolt with the correct length should be used as a protective measure for avoiding condenser to Radiator end tank damage during installation. Secure the bottom of the Radiator within the lower pads before implementing the condenser and tightening a/c condenser mounting bolts to 13 nm (115 inch lbs.). Finish the installation of transaxle oil cooler pipes by leaving them to click into Radiator quick connect fittings before soft pulling for retention and placing plastic caps over the quick connect joints. Secure the transaxle oil cooler pipe bracket bolt on the lower tie bar by tightening it to 10 nm (89 inch lbs.). The hose clamp pliers (J 38185) helps install upper and lower Radiator hoses to the Radiator before attaching the coolant recovery hose to the Radiator neck with the hose clamp pliers (J 38185). Mount the upper tie bar followed by installing the upper Radiator seal then proceed with filling the cooling system lastly checking the transmission oil level.

The first step to replace a Radiator involves draining the engine coolant then removing the upper Radiator seal together with the upper tie bar. The hose clamp pliers (J 38185) should be used to disconnect the coolant overflow hose from the Radiator before plugging the hose. Remove the upper and lower Radiator hoses from the Radiator through using hose clamp pliers (J 38185) and set them beside you during the process. The bolt securing the transaxle oil cooler pipe should be removed from the lower tie bar before extracting the cooling fans. Hold the plastic cap when sliding it off transaxle oil cooler pipe quick connect fittings before using the cooler quick connect tool (J 41623-B) to unplug upper and lower transaxle oil cooler pipes from the Radiator. First detach the a/c condenser by removing its mounting bolts then disconnect it from the Radiator in order to extract the Radiator from the vehicle. The bottom of the Radiator should be placed into the lower pad followed by condenser installation onto the Radiator while using a special length bolt to connect end tanks of the condenser to the Radiator. Follow the installation instructions to push upper and lower transaxle oil cooler pipes into the Radiator quick connect fittings until a "click" is heard while also placing plastic caps over the quick connect joints. Then tighten the a/c condenser mounting bolts to 13 nm (115 inch lbs.). Replace both cooling fans and the transaxle oil cooler pipe bracket bolt on the lower tie bar while tightening the bolt to 10 nm (89 inch lbs.). The hose clamp pliers (J 38185) should be used to install both upper and lower Radiator hoses on the Radiator and establish the coolant recovery hose connection to the Radiator neck. You should complete your maintenance by installing the upper tie bar then adding an upper Radiator seal before filling the cooling system and checking the transmission oil quantity.

Install the upper and lower radiator hoses, connect the coolant recovery hose to the radiator neck, install the upper tie bar, the upper radiator seal, and fill the cooling system.

Never spray water on a hot radiator to avoid steam-related injuries.

Position the upper and lower radiator hoses out of the way.
