I was wondering if there is anything that would suggested as preventative maintenance on my daily driven 2001 Silverado 4.8L 4l60e 234K . I has 3.42 gears, the Jegs Off Road y-pipe, electric fans, and a 140amp alternator.

 

I changed my plugs, wires, brake fluid, power steering fluid, coolant, battery, air filter and PVC valve just to make me feel better more than anything. All were pretty cheap.

 

Okay Thanks

 

plugs, wires, 02 sensors, fuel filter, belts, water pump and grab the idle pulleys and give them a tug and decide if you want to replace them. run a can of sea foam through the tank (after the new filter), clean the throttle body. rock on.

 

I might go overboard but i replace radiator, waterpump, Tstat every 100k-120k.
Belts,brake fluid, battery, coolant every 3 years

 

Change the rear fluid, I'm sure it needs it.
