If your Nissan Altima is equipped with an automatic transmission, disconnect the cooler hoses and plug them to prevent leaks. Disconnect the negative battery cable, unhook the fresh air duct and continue taking off the upper radiator hose and the lower radiator hose. Inspect the radiator hoses for signs of wear and replace the hoses if you see visible bulging or cracks.

Remove the air conditioner condenser and radiator core. Pull the radiator out of the vehicle and unhook the fan assembly and attach it to the new radiator. Install the new radiator, with fan assembly, into the vehicle. Install the new radiator into the vehicle. If applicable, reinstall the air conditioner condenser, radiator core and automatic transmission cooler hose.

Attach the radiator cap somewhat loosely and start the engine. Let the engine run for a few minutes always checking for proper fluid levels. Adjust the fluid level by adding more if necessary and then put the radiator cap on securely.
