2004 Chevrolet Silverado 1500 Parts Questions & Experts Answers

• Q: How to clean the throttle body properly on 2004 Chevrolet Silverado 1500?

  A: Begin the Throttle Body cleaning process by removing the air cleaner's outlet duct and inspect the bore and plate for deposits. Make sure to open the throttle plate for full surface visibility. Strong solvents and immersion cleaners must not be used on assemblies containing throttle position (TP) sensor, idle air control (IAC) valve, or sealed throttle shaft bearings because they have the potential to cause electric component or seal damage and may break down non-serviceable bearing grease. Wire brushes along with scrapers must be avoided since they damage the Throttle Body components and cleanup solvents with methyl ethyl ketone can cause serious damage. Use a clean shop towel to wipe out the Throttle Body bore along with throttle plate until they are thoroughly clean using top engine cleaner gm p/n 1052626 (Canadian P/N 993026) or any equivalent product. Excessive deposits require Throttle Body disassembly during thorough cleaning which should be performed by using a parts cleaning brush that avoids contact with any solvents. Install the Throttle Body after cleaning while also reattaching the air cleaner outlet duct.
