I recently put a new (rebuilt) starter and a new battery in my Chevy Suburban at the same time. The old battery had 775 CCA, the new has 875 CCA. The new starter seems to *really* crank over. Here's my question - Is the new battery pushing the starter harder (possibly decreasing its life expectancy) -OR- does the starter only pull the amps it needs, not more, so the extra 100 are sitting in reserve so to speak. I realize that the old worn-out starter had 120K+ on it, but the noise is considerably louder. It's not a grinding sound so I don't think it's a flywheel spacing issue, it just really seems like the starter is cranking really hard. Almost too quickly maybe?
Any thoughts? Thanks....
