How do you replace the upper and lower radiator hose on a 1991 Geo Prizm?

To replace the upper and lower radiator hoses on a 1991 Geo Prizm, first ensure the engine is cool and then drain the coolant from the radiator. Using a screwdriver, loosen the hose clamps at both ends of the upper and lower hoses, then carefully remove the hoses. Install the new hoses by sliding them onto the radiator and engine fittings, securing them with the clamps. Finally, refill the radiator with coolant and check for leaks.
