2002 Chevrolet S10 Throttle Body Parts and Q&A

• Q: How to clean the throttle body properly on 2002 Chevrolet S10?

  A: The cleaning process for the Throttle Body begins with air cleaner outlet duct removal to examine the Throttle Body bore and throttle valve plate for deposits. Make sure to open the throttle valve for thorough inspection. Assemblers containing the throttle position (TP) sensor, idle air control (IAC) valve along with sealed throttle shaft bearings should not be cleaned by immersion cleaners or treated with strong solvents because these procedures harm electric components and o-rings and degrade the grease on the non-serviceable throttle shaft bearings. The use of wire brushes or scrapers would damage Throttle Body components while methyl ethyl ketone cleaners should be avoided because they damage surfaces. Use gm top engine cleaner (P/N 1052626) or an equivalent product to wipe down the throttle bore and plate inside the Throttle Body with a clean shop towel. Thorough cleaning of excessive deposits requires the Throttle Body disassembly followed by brush maintenance without solvent immersion. Reinstall the air cleaner outlet duct once you complete the reinstallation of both the Throttle Body and all its components.
