To replace the radiator on a 1990 Cadillac Brougham, start by disconnecting the negative battery cable and draining the coolant from the radiator. Remove the upper and lower radiator hoses, as well as any mounting bolts or brackets that secure the radiator. Carefully lift the old radiator out, then install the new one by reversing the steps: secure it in place, reconnect the hoses, and refill the coolant. Finally, check for leaks and ensure the system is properly bled of air.
