Timing Chain Maintenance

[lady3bglover]

Hello Tech...

 

I have a '02 Silverado Step Side, 5.3l V8. I believe that I have a timing chain. And I was told that when maintaing the timing the water pump must be taken care of.

 

The truck has 90k miles on it. I've already change the plugs, wire, changed my air filter to K & N. What else should I have done to the truck? I have the Hypertech Programmer, and I'd like to have the truck maintained before I programmed.

 

Thanks for your time.
