Water pump on 84 300d

I know that my problem seems small compared to those who lost loved ones in NY.

Simply, is the water pump in an 84 300d difficult to replace. I believe that mine has just expired by the presence of gross coolant loss in the front mid section of my car. The car has 245,000 and does not have any oil in the leakage. my engine oil also appears free of coolant. I am glad that I found this problem before I did any real damage.

I think that this is the original water pump.

thanks for your help

and sorry for anyones loss
