Think again. It's a major PITA.
My replacement AC/Delco battery was leaking and had corroded the Pos battery cable fitting so badly, I knew I was going to have to replace it. Anyways, I figured I would let it go until I had the time and the money to fix it. In another thread someone stated I should go and replace the cable in addition to the battery. Last week the battery died when I was cleaning the inside of the truck, and today it died when I was working on the doors. Well, I figured I shouldn't risk getting stranded and I went to a store that carried the positive cable ($40..AC/Delco PN 4SX402FSA). Well, I drove 20 mins there and when I went to leave...nothing. Didn't even crank once, and everything died...click click click. So I got a friend to give me a ride to Pep-Boys to get a battery (AC/Delco 78DT) and then we went back and jumped the truck off and I got home, loaded up some tools and went to the fire dept where I could do it indoors. When I got there I shut it off and it refused to start not even one minute after I shut it off. Battery was D-E-A-D dead.
Now for the fun part
. I disconnected the Neg and cut off the positive, since it was so corroded I couldn't even break torque on the bolt. Removed the old battery and got to work disconnecting the cable from the alternator and the starter. First off...the damned bolt for the alternator would be easy to get to, but all the harnesses from the PCM, etc are right over it. It took some contorting but I got that one off somewhat easily. The starter one is a PITA
. You can't really see it or reach it from above. I had to jack up the truck and slide under it and take it off by feel. Then I had to undo all those little cable clamps. I found that the battery acid had indeed permeated the entire cable, as there was discoloration and evidence of corrosion in the cable all the way to the ends...so it made me glad that I replaced it. Installation is just as big a pain as removal, but at least you know where the clips are, etc. It took me about 4 hours. Truck started on the first try and everything is fine.
Only question is...when I start it now, sometimes the truck drops reallll low on RPMs for a second, is this normal for it to relearn its settings? It was without any power for over 4 hours.
