Tip & How-To about Chevrolet Silverado

Battery Terminals & More

Today's tip is about battery terminals & how to protect them.
I have seen many opinions on this subject, the one i disagree with most seems to be popular among a few "experts" even on this site. So here is my 2 cents on the subject...

Is it a good idea to put Vaseline on battery terminal posts to prevent corrosion? - Not really, & this is why...

Under hood temperatures will cause the petroleum jelly to liquify, and run down between the cable and the terminal - effectively creating an insulating barrier.

I've cleaned up several of these well-intentioned mistakes that were discovered when a car would not start.

There is a battery terminal spray coating specifically formulated for the job, and available for a couple of bucks at the auto parts retail stores like Pep Boys, Auto Zone, etc....That is the correct product to use.

Battery & alternator both good, but wont start without jump off, atleast once a day.

Your battery will not be "good" if you can jump start the car from another power source. If it is a 2014 model it will be the original battery.

Unless you have tested the cold cranking amps the battery is producing you cannot say if it will turn the starter motor or not. A good battery would kick the starter motor over. If you can jump start the car by connecting another power source to the battery terminals it will not be a wiring issue either.

If it's a 2014 it should still be covered by new car warranty (but not if the problem is just a failed battery which is subject to the applicable battery warranty)./

Engine stalls while driving!

as your description is a little uncertain that is why the answer are a little mixed
however the basis of the description indicates a battery problem , probably loose/dirty battery terminals or loose /dirty ground wire to the engine
check the ground wire condition
