How do you change the radiator on a Nissan Quest?

To change the radiator on a Nissan Quest, 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 disconnect the upper and lower radiator hoses, as well as any electrical connections. Remove the mounting bolts or screws securing the radiator, lift it out, and install the new radiator by reversing the process. Finally, refill the cooling system with the appropriate coolant and check for leaks.
