I own a 2009 Silverado LT with a 5.3L, that I bought back in Sept 08. The odometer just hit 30K. Is there any service I need to do to my truck ? Besides the usual oil changes, rotate tires, wheel alignment. The only mods i have are a k&n filter and a 2.5 true dual exhaust with 40 series flowmasters. Any info will be helpful

 

6.0hhhhhhhhhhhh

 

31k..

 

I would drop the trans pan and change the filter and fill it back up with about 5 quarts of dex VI. This fluid is long life, but the filter still gets dirty. I like doing this every 25-30k. Also I would check all fluid levels, coolant, power steering, and while your there the washer fluid. Also if it were mine I would consider flushing the brake fluid, and ps, especially if it looks dirty. You could even check the level in the rearend, (front too if its 4wd).

 

I did a pan drop of my trans. But I also added a servo around that time too because I was getting my tune soon so I wanted to add all the little things I could.

 

Differential fluids................

 

Meh, I'd do that around 100k, really no point in changing it so early.

 

Bleh i i'm about to hit 48K on mine, bought it back on Nov 07.

at 50 i'm doing the filter in trans and new fluid. Brake flush, maybe rearend fluid too.

 

What about 100k? Mine even has a little miss to it. I just got it tho.......what should check/replace?

 

100k id do plugs and wires...
dont go cheap, use acdelco plugs and a good set of wires...
