Regal V6-173 2.8L (1988)
Throttle Body: Application and ID
Throttle Body Identification
The throttle body assembly repair procedures cover component replacement with the unit on the vehicle. However, throttle body replacement requires
that the complete unit be removed from the engine.
An eight digit part identification number is stamped on the bottom of the throttle body casting next to the coolant cover. Refer to this number if servicing,
or part replacement is required.
