One problem related to radiator has been reported for the 1996 Nissan Maxima. The most recently reported issues are listed below.
Water pump leaks radiator coolant. This has led to engine-overheating and may cause severe engine failure (a safety issue). On checking with dealer, the estimated repair and replacement of water pump may cost around $750. This is an unusually high cost for water pump replacement. With the car being a 96 model having only a mileage of about 50 k, this kind of water pump failure is probably unseen on most other car models. Therefore, it is suggested to the manufacturer to investigate into possible design defects of the water pump.
