I have been watching you tube videos on how to pull hvac box to replace heater core and AC evaporator. All have been different years and 6 cylinders.
They all seemed to have 2 bolts behind engine, 2 more near where ac and heater hoses go in and 1 more towards fender. Mine is 5.2 v8 and has 1 bolt upper but no bolt lower just behind distributor. Am I right? Like to know before I tackle this. Thanks,JamulDoug

If you have the high end HVAC control system there will be differences in the electrical connectors. Here are a couple of pictures of the bolt patterns:

If you need copies of the FSM and Parts Catalog, here's a link to my drop box. The manuals wont be there forever, but at least the next several weeks... I urge everyone to have a copy.

I highly recommend when you get ready to put it all back in there to put in the A/C leak dye before charging up the system and check for leaks. It is also a great excuse to get a manifold set, A/C line coupling tools, and a vacuum pump for A/C work....

Good luck.
I have a 5.2 V8 parts rig here. I can check the bolt pattern tomorrow

Never hurts to change the accumulator/drier. But if you haven't had a compressor failure or some such thing happen it is not necessary. If you do, you will also need to add some refrigerant oil since it accumulates in the drier
