To remove the radiator, start by disconnecting the battery cable from the negative terminal and raising the front of the vehicle on jack stands. Remove the lower splash shields and drain the cooling system, saving the coolant if it's in good condition. On fuel-injected models, remove the air intake duct. Remove the bolts and upper radiator support from each end of the radiator upper tank, disconnect the coolant reservoir hose, and loosen the upper and lower hose clamps to detach the radiator hoses. Disconnect the cooling fan connector and, if applicable, the cooler lines for automatic transaxle models. Carefully lift out the radiator, ensuring not to spill coolant or damage the vehicle. Inspect and replace the lower radiator rubber supports if necessary. If the radiator needs repair, have it serviced by a professional. Clean the radiator of bugs and dirt without bending the cooling fins. To install the radiator, follow the reverse of the removal procedure, ensuring the rubber supports are properly seated. Fill the cooling system with the correct antifreeze and water mixture, start the engine to check for leaks, and add more coolant if needed. For automatic transaxle-equipped vehicles, check and add fluid as necessary.
