2002 Buick Rendezvous Parts Questions & Experts Answers

• Q: How to clean the throttle body properly on 2002 Buick Rendezvous?

  A: Begin Throttle Body cleaning operations by taking out the air cleaner outlet duct together with any air inlet screen present. The Throttle Body bore and throttle valve plate need inspection for deposits and the throttle valve must be opened for proper visual examination. Strong solvents and immersion cleaners must be avoided when cleaning throttle position (TP) sensor assemblies alongside idle air control (IAC) valve units and sealed throttle shaft bearing assemblies because such cleaning solutions damage electric components and seals while potentially degrading the grease on non-serviceable throttle shaft bearing assemblies. Users should evade wire brushes and scrapers which may harm Throttle Body elements and must avoid chemical cleaners that include methyl ethyl ketone. Use gm top engine cleaner, p/n 1052626 or equivalent solvent to clean the Throttle Body bore as well as throttle valve plate with a clean shop towel. Through cleaning with brush tools you can treat severe Throttle Body deposits by disassembling the unit followed by solvent-free parts brush scrubbing. Assembly procedures start with cleaning the Throttle Body before installation of the air inlet screen if present and positioning the air cleaner outlet duct into place.
