Help With Battery
I personally went out and bought a Optima red top. They are pricey but worth every penny and dont have the issues that the delco and most other side mounts have with leaking acid.
There are only about 2 or 3 battery manufactures in the US that make a majority of the batteries, so even though it may say duralast it could be the same battery as a Delco.
If you can afford to spend the money get the Optima. They have a 72 month warranty, first 3 year is full replacement and the last 3 years is prorated. I lost a cell in mine right at the 3 year mark, sears replaced it no charge without no complaints.
Make sure to clean up all of the old acid from the delco puker. Or you will have some serious rust issues down the road. When mine went, ended up replacing battery cable, pulling battery tray-resv. Clean prim, paint that area of the engine bay.
Have seen other cars that had the same problem, with no or poor cleaning and you can see the damage the was caused.
