1987 Other Dodge Models Need to locate water pump

Engine problem
1987 Other Dodge Models 6 cyl Two Wheel Drive Automatic 100K miles

I am having my radiator on my 1987 Dodge 600 series sedan flushed and reconditioned. I was advised to look at the water pump and flush it out since it hasn't received any attention in all the years I've had the car. I was just having some overheating problems (minor). The car is in great shape except for the radiator and I've had everything overhauled in it except for the water pump. Please let me know where the water pump is located in this model and the easiest way for me to remove it, if necessary and service it. Thanks.
