Preventative maintenance

[countryguy1717]

Coming up on 120k. What's y'alls take on preventative maintenance besides oil spark plugs? Should I replace water pump?

[davester]

only if it's leaking.

maybe the serpentine and/or a/c belts if they are pretty cracked, and check/replace the idler/tensioner pulleys if they are making noise.

spark plug wires

Have you changed the driveline fluids?

My take? Routine maintenance is preventative maintenance. Routine maintenance is more frequent than the book "Normal" maintenance. In fact, IMO, there is no such thing as normal. All service is severe so use the "Severe" schedule and if you book hasn't such a table halve the normal schedule. Now that said....

 

You won't find in that book a replacement time or miles for most hard parts. Yes there are a few, like plugs. But water pumps, brakes, etc. have lives dependent on service/use and environment.

 

As Dave mentioned, Inspect and replace what needs replacing, service what does not and as diyer2 mentions, don't forget the fluids we don't routinely look at or change. (Brake fluid power flush, coolant ever 5 years and so on.)

Are u the original owner? Do you have the maintenance records on what has been done?

Personally, I do the fluids more frequently that GM says. If no previous records on fluid changes I would: 

1. drain & fill transmission ATF, about 4 quarts which can be sucked out the fill tube. Not sure which transmission u have but assume 6 speed. It take Dexron vi

2 drain & fill transfer case if 4x4. Dexron VI 

3. I'd also drain & fill front & rear differentials 

4 at the least, replace brake fluid in reservoir. 

5. Replace your air filter & cabin filter.

Just my opinion
