Installation and Ordering Notes

Confirm the complete reference character by character and compare all gallery views before ordering. Fitment can vary by market, VIN, engine code, production date and physical configuration. Professional installation is recommended. Electronic throttle bodies may require the vehicle-maker’s relearn procedure; cable-drive units require throttle-cable travel, blade-clearance and TPS/IAC calibration checks.

Catalogue Research and Confidence Boundary

• Dorman 977-820 manufacturer catalogue with direct OE crosses 12570790 and 19420034 (aftermarket manufacturer product catalogue)
• GM 19420034 catalogue showing replacement of 12570790 and exact vehicle/engine coverage (vehicle parts catalogue)

The protected Jiandaoyun reference set is the identity baseline. Dorman directly crosses 977-820 to GM 12570790 and 19420034; the GM catalogue confirms the supersession and stated vehicle/engine coverage. No additional seller-only number was promoted.
