alternator and water pump
 

02 Chrysler Town and Country 3.8 engine

At what mileage did you replace your alternator?
At what mileage did you replace your water pump?

Both of Them are "REPLACE AS NECESSARY"..so there really isnt a Time frame. There are plenty of 1999's with original pumps and alternators, and in contrast, there are 08+09's that have had them replaced already....If it isnt leaking or making Noises...Leave it alone.

are u kidding me u really think making a different thread about the same thing U had asked already some one will give u a different answer?
