2003 Buick Park Avenue Throttle Body Parts Questions & Experts Answers

• Q: How to clean the throttle body on 2003 Buick Park Avenue?

  A: The air cleaner intake duct and air inlet screen need to be removed during the Throttle Body cleaning process. Check the Throttle Body bore and plate of the throttle valve by opening this valve to expose all surfaces for inspection. Soak the Throttle Body bore and throttle valve plate with gm top engine cleaner (P/N 1052626) or an equivalent product using a clean shop towel. Immersion cleaning solutions and harsh solvents should never be applied to Throttle Body assemblies due to their ability to damage tp sensors and iacs and throttle shaft bearings while dissolving non-serviceable throttle shaft bearings' protective grease. Utilize only brushes or scrapers made of wire because they can damage components and avoid cleaners that contain methyl ethyl ketone which will damage components and provide no value for this cleaning operation. Excessive deposits require Throttle Body disassembly for parts cleaning brush work while maintaining the component out of cleaning solvents. Installation begins with the Throttle Body and ends with the reinstallation of the air inlet screen and air cleaner intake duct.
