Hello my name is XXXXX XXXXX I will be more than happy to assist you.


Here are the instructions to replace the Evaporator Core.


Note: The instructions don't say to remove the Inner Finder Well, If you remove it, it will make getting to the lower bolts for the evaporator box easier.

Matt , thank you very much ! Doesnt look like to bad a job . What would I expect to pay a meccanic to do this job ? I am AC certified , trained by the postal service but have a bad back . Also do I have to do anything to the acc / dyer . A charge lasts me for about a week but i checked with a leak detector and it goes off when I put it in the inside vents , so I know its the evap . One other question , I should put back about the same amount of oil in it in the acc when i'm done ?

The labor guide shows 5.1 hours, but I have done them in under 3 hours.


You do not have to replace the acc/dryer just pull it off and plug the holes if it will be off for a while.


It is common for the Evap to go bad.


There is no oil amount listed to add back in in the repair manual. Normally I will add about 2 ounces to the Evap.
