2004 Buick Rendezvous Parts Questions & Experts Answers

• Q: How to clean the throttle body properly on 2004 Buick Rendezvous?

  A: A proper cleaning process for the Throttle Body begins with removal of the air cleaner outlet duct and the air inlet screen depending on vehicle specifications. Check the Throttle Body hole and throttle valve plate for buildup then check all surfaces by unlocking the throttle valve. The use of immersion cleaners or strong solvents should be avoided when cleaning assemblies that incorporate throttle position (TP) sensors or idle air control (IAC) valves or throttle shaft bearings because such chemicals can damage sealed parts or o-rings and erase lubrication from non-serviceable bearings. The Throttle Body components require protection from wire brushes and scrapers and cleaners with methyl ethyl ketone must be avoided. Use gm top engine cleaner p/n 1052626 alongside clean shop towels to clean both the Throttle Body bore and throttle valve plate. Additional deposits should require Throttle Body disassembly using a parts cleaning brush while the components stay free of any cleaning solvents. Throttle Body reassembly occurs first followed by air inlet screen installation when needed before the air cleaner outlet duct gets installed.
