Throttle Body: Service and Repair
Throttle Body Service
CLEANING
The throttle body assembly repair procedures cover component replacement with the unit on the vehicle. However, the throttle body replacement
requires that the complete unit be removed from the engine.
An 8 digit part identification number is stamped on the bottom of the throttle body casting. Refer to this number if servicing, or part replacement is
required.
While on-vehicle or off, clean the throttle bore and valve deposits using the carburetor cleaner and a parts cleaning brush. Follow the instructions on
container.
THREAD-LOCKING COMPOUND
NOTE: In precoating screws, do not use a higher strength locking compound than recommended. Doing so could make removing the screw extremely
difficult or result in damaging the screw head. The service repair kits are supplied with a small vial of thread-locking compound with directions for use.
If the material is not available, use Loctite 262 or the equivalent. Do not use a cleaner that contains methyl ethyl ketone, an extremely strong solvent, and
not necessary for this type of deposit. The throttle body metal parts may be cleaned following the disassembly in a cold immersion-type cleaner such as
GM X-55 or the equivalent.
NOTE: Do not immerse the TP sensor and IAC valve in any type of cleaner because they are electronic devices.
