Hello I will help you with your question,
Mazda has extended the warranty coverage to your heater pipes to 7 years from in service date. You may be covered for this If not Mazda has issued a TSB about this problem and has redesigned the material and protection of the coolant pipes So I will give you that if you are not covered. If you have rear AC the warranty time to replace the pipes is 4.7 hours with AC less if no AC. This is in a shop with a lift and full tool set.
The $1300 question is what is your inservice date?
The dealer will be glad to see you as they get paid from Mazda so they will fill a service bay for a day!!
Here is the Campaign notice
For certain 2000-2003 MPV vehicles, the warranty coverage for the rear heater pipe and hose assembly is extended to 7 years from vehicle in-service date with no mileage limitation.
CONDITION OF CONCERN
On certain 2000-2003 model year MPV vehicles, the accumulation of road salt may cause rust and corrosion to the rear heater pipe and hose assembly. If the rust and/or corrosion is severe, there is a possibility of an engine coolant leak.

Mazda will notify U.S. owners by first class mail beginning June 30, 2005. Owners will be advised they do not need to come in for inspection if their vehicle is functioning normally.
