How to check a water pump on a 1998 Dodge Dakota V6?

My 1998 Dodge Dakota V6 heater only gets warm, I have replaced the thermostat. I have back flushed the heater core. The heater hose coming from near the thermostat gets hot, but the hose coming from the heater core going to the water pump only gets warm. The large hose coming from the thermostat is hot near the engine, but is only warm near the radiator. Is the water pump bad? If I open the radiator cap there is no signs of circulation. How do I check the water pump?



Thanks,

Blocked heater cores is a common problem on that model truck, also make sure you coolant lever is good.
