Working in the telecom business we always add battery grease to our terminals to prevent corrosion. I think a tube of it is a few bucks at your local auto parts store.

I have had good results with wheel bearing grease.

Like everyone else said, either scrub it or replace it. Add a washer. Hit it with some terminal protector. Move on.

Eventually, though, you will need to replace the battery. That corrosion is doing nothing for its health and it's leaking.

Ouch, brutal! When I said hard, I meant harder than it needs to be. Almost every other vehicle out there doesn't require you to remove the windshield wipers and another part of the vehicle just to deal with clogged nozzles. Most other vehicles just require you to pop the hood and everything's right there.

I was just frustrated with all the extra crap I had to do to fix a simple problem. I hate having to buy extra tools that I won't ever have to use again except for this 10 year old truck. The spark plug issue for the 04-08 is another issue I thought about. It was a simple tune-up that turned into a $500+ job that I couldn't do myself.

But back on track, I managed to find what I needed. Two of the three positive terminal wires had lugs on them, I just had to cut the main 2 gauge wire and put a lug on it. None of the tools I had could crimp the lug on to the wire so I just twisted it in and wrapped the lug and wire tightly with electrical tape.

All the aftermarket terminals had 5/8" or greater bolts on them so of course I had to pick up 1/4" bolts that would accommodate the existing lugs. So I have everything working but it was still more work than I preferred to do. But now I learned my lesson. Preventative care is important with batteries. I made sure to clean and then coat the terminals and connectors with some dielectric grease.

Fair enough, I really wasn't trying to be harsh. Just didn't think those items would be considered hard. Glad you got it working but I'd fear the terminal not being crimped. These trucks are prone to many weird issues just from a bad battery connection. If you have ANY issues come up even if you think theyre not battery related I'd look at that terminal. Tape only holds up for so long.
