When you put off those yearly coolant changes, you're not just putting your car in danger of freezing up or overheating: You're also starving your Nissan water pump of lubrication. The Nissan water pump contains seals and bearings that are internally-lubricated, but that also get some additives from the coolant. When the coolant is worn out, the Nissan water pump lubricant is depleted. Your Nissan water pump is much more likely to wear out a seal or a bearing when the coolant isn't changed on a regular basis. Of course, if your coolant is so old that it freezes in the block, your Nissan water pump will be worn out the second you try to start your car. The Nissan water pump impeller blades will be destroyed by the ice almost instantaneously.
