To remove the radiator, start by disconnecting the cable from the negative battery terminal. If equipped, disconnect the automatic transaxle cooler lines. Then, remove the radiator along with the fan, making sure to release the air conditioning condenser from the radiator clips. Carefully lift out the radiator, being cautious not to damage the fins on the radiator or air conditioning condenser. Inspect the radiator for any leaks or damage. To clean the radiator, spray it with a garden hose nozzle from the back side to remove bugs and dirt. Before installation, flush out the radiator with a garden hose. Additionally, check the rubber mounts on the bottom of the radiator for wear or deterioration and replace them if necessary. To install the radiator, guide the radiator/fan assembly into position, ensuring that the rubber mounts on the bottom are properly seated into the support. Attach the condenser to the radiator and tighten the radiator and air conditioning condenser bracket bolts securely. After installation, fill the cooling system with the proper mixture of antifreeze and water. Start the engine and check for any leaks. Once the engine reaches normal operating temperature, recheck the coolant level and add more if needed. Lastly, check the transaxle fluid and add more as necessary.
