100,000 mile service?

[huero]

Hey guys.
My 2000 Silverado (5.3 and auto trans) just hit 100,000 miles and was wondering what service is requiered if so. I have changed the fuel filter along with oil, trans, radiator, differential fluids regularly but nothing else. I believe the spark plugs need replacement at this milage. Anything else? Thanks in advance, huero.

Here is the maintenance schedule from your OWNERS MANUAL!
Maintenance Schedule
Using The Maintenance Schedule
Because of the different ways GM vehicles are used, maintenance needs vary. More frequent maintenance intervals than found in this manual may by needed. When reading this schedule, keep in mind the conditions under which the vehicle is operated. Adjust the maintenance intervals accordingly.

The proper fluids and lubricants to use are listed in Fluid and Lubricant Recommendations . Use the proper fluids and lubricants whenever servicing this vehicle.

The maintenance schedules found in this manual are for vehicles that:

• Carry passengers and cargo within recommended limits. Refer to Label - Vehicle Certification in General Information.

• Are driven on reasonable road surfaces within legal driving limits.

• Are driven off-road in the recommended manner.

• Use recommended unleaded fuel.

Scheduled Maintenance
The services shown in this schedule up to 100,000 miles (166,000 km) should be performed after 100,000 miles (166,000 km) at the same intervals. The service shown at 150,000 miles (240,000 km) should be performed at the same interval after 150,000 miles (240,000 km).

GMMerlin, you don't happen to have a "map" of all the grease zerks in the chassis, do you? I know I'm missing some...

Thank you, GMMerlin.

A few more things that may not be on the list.
Also Good time to check brakes and belt and hoses and flush coolant and brake fluid flush/ change.
Also watch the fuel pressure regulator. You can check it by pulling vacume hose off and loking for fuel in vacume line.
Good luck and take good care of it and someday you may get to do another 100K check up at 200K.

Thanks guys, when should things like the oxygen sensor, catylitical converters, etc.etc. be changed? I appreciate your responses.

No I don't have one...but one you may have overlooked could be the one on the driveshaft.

Some people believe that O2 sensors should be replaced at 100K.
I don't replace the sensors until there is a concern (fuel mileage, engine performance)..typically I have found that if your engine is in good running order, the O2 and converters should last a good long time....when you have a concern with misfires, this is when the life of the O2 and converters can degrade.

As GMmerlin said.
If they are not broke do not replace them.
Cats and newer 02 sensors are very hard to kill.
I have saw most of them outlast the car.
250-300k
The key to cats living a long time is proper tune up and engine running good.
If a cat or 02 sensor problem the PCM will set a code.

You guys Rock!! I feel alot better about my maintanance habbits. Being that it hit 100,000 I went out and bought the spark plugs for the truck part # 41-985. Do they have to be gapped? They look so easy to damage. I forgot to ask they guy at the parts department that question. If, so what is the proper gap?

Always check the gap and also center the tip on them.
Align/center the platumin tip with the electrode.
Hold the plug with a 5/8 wrench and take a pair of pliers and twist the tip side ways a hair to center it the tips if not centered.
You will not find may sets of plugs that are all gaped or centered good.

AC Delco P/N 41-985, is gapped to 1.01mm (0.040 inches) when the spark plug is made. The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used.

The good book says do not move them.
I was just wondering if you find many plugs with the tips not centered or the platumin dot not centered on tip or with the electride?
It seems like the ones I get about half of them are not centered good.

GMMerlin you are an ace. Do you know if the parts department will give me a hassle for returning a plug that is not properly gapped? I can not thank all you guys for your help. huero.
