x2.....On going with A/C Delco Plugs, and the ones you would want are the.....A/C Delco Iridium Tip Spark Plugs and this would also be a good time to go with a New Set of Plug Wires......and regarding the MAF Sensor Cleaner, Use Only CRC's MAF Cleaner.....and a Cleaning of the Throttle Body & Injector's is a item that should be done, if it has not been done in some time......I would Check the Belts and Hoses and replace if needed......on The Fluid's.....to add to what has been mentioned above......If the Brake and Steering Fluids have not been Flushed, now would be the time to think about flushing out for Fresh fluid's.
2003 Suburban 5.3 Tune-up-What all do I need?
Plugs
TB/MAF cleaner
Fuel filter
Air filter
All that stuff I know, but is there anything else? It has 136,000 miles, is there anything else I should do at this mileage? Don't kill me for this, but it has never had a tune up... But it had a coolant flush and fill with a water pump replacement at about 80k miles, and that's all the work it's ever had. (Bought it new)
