How to Tell If a Water Pump Is Going Out
 
 The water pump is the 
key component of your car's cooling system. The water pump is 
responsible for circulating coolant to the entire engine, and it gets 
its power from the engine. If any of the gea...rs,
 bearings or the shaft are impaired, the water pump can break, become 
cracked or stop working altogether. There are several signs you can look
 out for to determine if the water pump is worn out or is close to 
failing.
