How do i change my radiator in my Toyota van?

To change the radiator in your Toyota van, 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 and then disconnect the upper and lower radiator hoses. Remove any mounting bolts or brackets 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.
