Heater problem

4 cyl Two Wheel Drive Manual 130000 miles I need to replace the heater core and I'm wondering if there are specific steps to take and just how hard of a job this is. Anything special tips I should keep in mind?

Hello,

On some of the rangers there is a trap door that enables you to remove the core without removing the heater box. But if you don't have that then this will give you an idea of what you are in for when doing the job. Diagram (below).

Please let us know what happens.
