So my Tahoe is coming up on 100K in mileage, its at 98K about. So i started thinking about all the dealer services I've had with this vehicle, and I dont recall seeing in the the service reciepts where they changed out the plugs and wire and distributor cap, and even the water pump. Not sure if they did change them during certain services and just didnt list it in the details of the reciept. My first American car, Im used to my Acura where the distributor and wires and water pump get replaced every 90K. And since they're platinum plugs in my Acura, they get changed every 60K. So does chevy have longer change intervals for these parts? My Acura is about to hit 180K, so it got me thinking about my Tahoe. Thanks in advance!

 

No distributor anymore. Coil over plug is controlled by the ECM. I think the plugs are 100K. Water pump replacement is usually controlled by when they start leaking.

 

Generally on the Honda and other import engines, you would change the water pump at the same time as the timing belt. The reasoning is that you have to do a timing belt service to replace the water pump, so you might as well save the labor and replace it.

The 5.3 V8 does not have a timing belt and the water pump is easily accessible on the engine. No need to change it unless it is causing problems.

The owner's manual calls for an ATF fluid and filter change, transfer case fluid change and spark plug replacement at 100K.

 

Thanks for the info 73 and vester, much appreciated!

 

When you get to 245K let us know how it is still doing.
