How to clean the throttle body properly on Chevrolet Express 2500?

To clear the Throttle Body, first remove the air cleaner outlet duct and check the Throttle Body bore and throttle valve plate for deposits and check that the throttle valve is open to allow full inspection of the Throttle Body bore and throttle valve plate. Do not use immersion cleaners or powerful solvents near the Throttle Body assembly, including the throttle position (TP) sensor, idle air control (IAC) valve, and sealed throttle shaft bearings, as this can cause damage to electric components, seals, or o-rings and they can wash saw grease from the non-serviceable bearings. Do not use a wire brush or scraper as this can damage the components in Throttle Body also be careful of chemicals that contain methyl ethyl ketone. Clean the Throttle Body bore with a clean shop towel using gm top engine cleaner, p/n 1052626 or an equivalent product, and throttle valve plate. If deposits are too much, disassemble Throttle Body to clean deeply without immersing a parts cleaning brush. Clean and reassemble the Throttle Body and install it back along with the air cleaner outlet duct.

How to replace the throttle body assembly on Chevrolet Express 2500?

In order to replace the Throttle Body assembly, first remove the air cleaner assembly then the accelerator control cable, the cruise control cable and the vacuum hose. Then, disconnect throttle position (TP) sensor and idle air control (IAC) valve harness connectors, as well as disconnect coolant hoses from the Throttle Body and the vapor vent pipe. Take out the Throttle Body attaching nuts, then remove the Throttle Body and the gasket and get rid of the old one. Care would be exercised to not destroy the sealing surfaces when removing the old gasket from the aluminum surfaces and also avoid soaking the Throttle Body in cold immersion type cleaner since the throttle plate has sealing compound factory applied. For cleaning, use a spray type cleaner like gm x-66a or gm p/n 1052626 and make sure that the tp sensor does not touch any solvent or cleaner, same as with the iac valve. For installation, pick the Throttle Body with a new gasket, tighten it with its attaching nuts at 10 n.m (89 lb in), and reconnect the coolant hoses, accelerator control cable, cruise control cable, tp sensor, iac valve's electrical connectors, and vacuum hoses. At last, reinstall the air cleaner assembly and make sure the accelerator pedal moves freely when the engine is off, and recheck the iac valve by turning the ignition on for 10 seconds, off for 5 seconds, and starting the engine to check the idle speed.
