A leaking or broken radiator needs to be repaired or replaced as soon as possible to avoid permanent engine damage. Following these simple steps, you will be able to change the radiator in your Nissan car model in a matter of minutes.

Drain the cooling system into a resealable container.

Disconnect the negative battery cable and remove the coolant tank and bracket. Unscrew the bolts holding the upper mountain bracket, and remove the bracket.

Remove the upper and lower radiator hoses, and inspect them carefully. If they are cracked or worn, it's a perfect time to replace them. If your Maxima has oil cooler lines, remove them now. Remove both the cooling and condenser fans, along with the fan motors.
