2004 dodge durango oil pump change.Is it complicated? do I have to take the engine apart?

Typically you have to get under and see if you have room to drop oil pan. Changing it out isn't hard its seeing if u can get pan off and clear of oil pump. Sometimes too u may need to raise engine. Google it and c if u can c anyone doing it. Typically it is a involved task.

By the way, why u doing it?

to save money on mechanic labor costs,.iv changed pumps on minivans but this is my first durango and shop told me it was a 23hr job and it would require me to remove engine and i needed a second opinion
