2005 Chevrolet Silverado 1500 Parts Questions & Experts Answers

• Q: How to clean the throttle body on 2005 Chevrolet Silverado 1500?

  A: The cleaning process begins by removing the air cleaner outlet duct before cleaning operations. Examine all Throttle Body bore and throttle plate surfaces by opening the throttle plate. Throttle Body bore and throttle plate need cleaning using gm p/n 1052626 (Canadian P/N 993026) or equivalent top engine cleaner along with a clean shop towel. The use of immersion cleaners or strong solvents on assemblies with a throttle position (TP) sensor and idle air control (IAC) valve or sealed throttle shaft bearings should be avoided because electric components or o-rings or seals may be damaged and the grease on non-serviceable throttle shaft bearings could be degraded. Use only solvent-wetted brushes or scrapers because they harm internal components and stay away from methyl ethyl ketone cleaners that unnecessarily damage parts. Through parts cleaning with brushes maintain the Throttle Body in disassembly format when heavy deposits exist but keep the brush solvent-free from immersion. Reinstall the Throttle Body after cleaning the component before you install the air cleaner outlet duct.
