To replace the radiator on a 2003 Oldsmobile Silhouette, first, ensure the engine is cool and disconnect the negative battery cable. Drain the coolant by removing the drain plug at the bottom of the radiator, then detach the upper and lower radiator hoses, along with any electrical connections and mounting bolts. Remove the old radiator and install the new one by reversing the steps, ensuring all connections are secure and refill the coolant before starting the engine. Always check for leaks after installation.
