  Q: How to service the throttle body on Chevrolet Aveo?

  A:

  Start by removing the air cleaner outlet duct when servicing the Throttle Body. Check the Throttle Body bore and throttle plate through plate opening for buildup then examine the entire plate surface. Strong solvents and immersion cleaners should never be used on the Throttle Body assembly because they can damage both the idle air control valve alongside the Throttle Position Sensor and the sealed throttle shaft bearings and components that utilize o-rings or seals. Throttle Body damage from wire brushes or scrapers and solvent damage to throttle shaft bearing grease are two reasons against their use during servicing. A cleaning solution with methyl ethyl ketone should be avoided because this aggressive solvent offers no benefit to the cleaning process. Utilize a clean shop towel with top engine cleaner gm p/n 1052626 (Canadian P/N 993026) or equivalent to clean the Throttle Body bore and throttle plate. Too much sediment requires complete Throttle Body disassembly where you should clean it using a parts cleaning brush before submerging it into any solvent. After completing cleaning the Throttle Body install it and reinstall the air cleaner outlet duct.

  Q: How to replace the throttle body assembly on Chevrolet Aveo?

  A:

  Starting the Throttle Body assembly replacement process begins by disconnecting two components: the negative Battery Cable and the intake air temperature sensor connector. First detach the air cleaner inlet duct from the Throttle Body before you disconnect both the electronic Throttle Body connector and the coolant hoses from this component. The Throttle Body requires its retaining bolts to be removed before you can take it out. After removal, discard the gasket. Before installation raise attention to the integrity of the sealing surfaces on the Intake Manifold by cleaning its gasket mating surface. Electronic throttle control valve removal is necessary before cleaning the Throttle Body in a cold immersion type cleaner because solvents or cleaners must never touch the electronic throttle control valve. To finish the installation put the electronic Throttle Body assembly with a new gasket and fasten its retaining nuts and bolts until they reach 15 n.m (11 lb ft). The electronic Throttle Body electrical connector requires reconnection following the installation of Throttle Body coolant hoses and attachment of the air cleaner inlet duct to the Throttle Body. The process ends with reattaching the negative Battery Cable then performing a cooling system fluid addition.
