2005 Chevrolet Blazer Throttle Body Parts and Q&A

• Q: How to clean the throttle body properly on 2005 Chevrolet Blazer?

  A: In cleaning the Throttle Body, you would first remove the air cleaner outlet duct. After removing the throttle valve housing and throttle valve plate, use your motor oil to soak these components to make it easier to remove any deposits on them. Then, use a suitable tool to clean the throttle valve plate and the bore of the Throttle Body, making sure that the throttle valve is open to allow thorough cleaning of all constraint surfaces. Clean the Throttle Body bore and the throttle valve plate with a clean shop towel with gm top engine cleaner (P/N 1052626) or an equivalent detergent. Care should be taken when using immersion cleaners or solvents on assembly parts that have the throttle position (TP), idle air control (IAC) valve, or sealed throttle shaft bearings in place, as this could damage electric components, sensors, and seals or parachute rings, and solvents also reduce the effectiveness of non-serviceable throttle shaft bearings. Avoid using wire brushes or scrapers for they can damage Throttle Body components and avoid cleaner containing methyl ethyl ketone for they can damage components in an unnecessary way. If deposits are too much, dismantle the Throttle Body for cleaning using a parts cleaning brush that should not be dipped into a patch of cleaning solvent. Disassemble the Throttle Body and clean it, then reinstall the Throttle Body and the air cleaner outlet duct.
