2002 Chevrolet Monte Carlo Parts Questions & Experts Answers

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

  A: Begin Throttle Body cleaning by removing air cleaner outlet ducts and air inlet screens. Observe the Throttle Body bore together with the throttle valve plate for any accumulated material while verifying the throttle valve motion for thorough assessment of interior surfaces. Immersion cleaners together with strong solvents should be avoided when cleaning throttle position (TP) sensor, idle air control (IAC) valve and throttle shaft bearing assemblies due to their potential damage to electric components and their ability to destroy o-rings or seals while potentially removing essential non-serviceable grease from bearings. The Throttle Body components can be injured by wire brushes or scrapers while chemical cleaners containing methyl ethyl ketone should be avoided. Use gm top engine cleaner (P/N 1052626 or Canadian P/N 993026) to clean the Throttle Body bore and valve plate with a clean shop towel. Starvation of deposits requires that technicians disassemble the Throttle Body to perform cleaning tasks using specific parts cleaning brushes which must operate without exposure to any chemical solvent. Cleaning is complete when the Throttle Body receives assembly followed by screening of the air inlet and finishing with the air cleaner outlet installation.
