Question about 2008 Chevrolet Impala
This is a BIG job involving discharging the a/c system and removing the entire dash assembly. If you think you want to do this, I strongly recommend purchasing a service manual from the manufacturer, or at least a Haynes/Chilton manual from your local auto parts store for guidance. I'll attach a link to a YouTube video showing the process for a similar car (Buick Lucerne). The exact steps won't be the same, but you'll get an idea of what you're in for.

if you have air conditioning you will need to take it to a garage and recover the r134, you will need to remove the dash to allow you to remove the heater box, it's an ugly job, I've done a dozen or so and can do it in about 6 hours now, the first time it was closer to 11 hrs, good luck

SOURCE: heater core
You have to pull the dash and all the lower fascia, then remove the box that houses the Heater Core Take the clamps off the heater hoses from the engine compartment side of the firewall and disconnect the heater hoses. Disconnect the bracket that holds the heater core in place from the inside of the passenger compartment (if present.) Carefully remove the heater core and discard it. Install a new heater core reversing the above steps.

Drain the coolant. Remove the dashboard first, then a bunch of air ducts, then the heater core cover. Remove the heater hoses in the rear of the motor, and finally the heater core.

SOURCE: bad heater core
look undre the passenger side dash and you will see a black box. Look closely and you will see screws in it around the edges. remove all the screws then remove the cover,there is the heater core, held in by 1 screw that is kinda hard to see. next look under the hood on the passenger side firewall right in front of the dash, you will see 2 hoses with clamps on them. loosen the clamps and remove the hoses. you may want to drain the radiator first but I never do

The battery is under the hood, just behind the passenger headlight.
There is a black bar that crosses over the battery and goes back towards strut tower. Remove this bar and the three bolts; probably a 12 or 13mm socket.
Remove the negative (black) battery cable with an 8mm socket or wrench. A 5/16" should work also.
Then remove the positive (red) cable with same socket.
Remove the battery clamp and bolt. Probably a 12mm socket with extension.
It's tight, but the battery can be removed.
Reverse instructions for installing the battery. (That includes hooking up the red battery cable first, then the black cable.)
