Before you remove the evaporator core from a 1998 Pontiac Bonneville you need to have the air pressure discharged. You will then need to remove the AC unit. You will need to remove some screws before you can remove the evaporator.
3100 V6 -- The firing order is 1-2-3-4-5-6. I know it seems wrong but that's what it is if you have a 3100 V6.4 Cylinder -- The firing order is 1-3-4-2.
