This throttle body is designed for GM 3.0L and 3.6L High Feature V6 engines (LF1, LLT, LY7). Please verify your original OE number before ordering. Not compatible with 2.4L 4-cylinder, 3.6L Twin-Turbo (LF3/LF4), or diesel engines. The 72mm bore is the factory specification for these applications.
This part is for GM 3.0L LF1 and 3.6L LLT/LY7 High Feature V6 engines ONLY. It will NOT fit:
- 2.4L 4-cylinder Ecotec engines (different throttle body)
- 3.6L Twin-Turbo V6 (LF3/LF4) (different calibration)
- Older 3.6L LY7 without electronic throttle (rare – verify)
- Diesel engines
- Any non-GM vehicles without verification
- Confirm your vehicle is equipped with the 3.0L LF1 or 3.6L LLT/LY7 High Feature V6 engine. Not compatible with 2.4L 4-cylinder, 3.6L Twin-Turbo (LF3/LF4), or diesel engines.
- Check your vehicle model and year against the fitment table (Cadillac CTS/SRX/STS; Buick LaCrosse; Chevrolet Camaro/Equinox; GMC Terrain).
-
Locate the original part number on your existing throttle body – look for
12616994,12609009, or12604075. - Verify the connector has 6 pins (rectangular blade terminal type, GM standard for this generation).
- Measure or confirm the throttle bore diameter is 72mm.
- Check the mounting bolt pattern (4 bolts) and air intake duct connection match the product photos.
- Note that a new mounting gasket is not included and must be purchased separately.
- Contact us with your VIN or a photo of your original part if unsure.

The LOREADA 72mm throttle body for GM 3.0L/3.6L High Feature V6 engines is a precision-engineered direct OEM replacement covering Cadillac CTS, SRX, and STS; Buick LaCrosse; Chevrolet Camaro and Equinox; and GMC Terrain. Built to strict GM OE standards with LF1, LLT, and LY7 engine calibration, it delivers factory-correct airflow, smooth power delivery, and stable idle. GM OE number 12616994 supersedes 12609009 and 12604075 — all are interchangeable. 100% new construction, not remanufactured, no core charge required.
- ✅ OE Fitment – Direct replacement, no wiring modification required. Matches GM OE numbers 12616994, 12609009, 12604075.
- ✅ 72mm Precision Bore – Factory-correct diameter for optimal airflow on 3.0L and 3.6L V6 engines.
- ✅ GM High Feature V6 Optimised – Engineered for Cadillac CTS/SRX/STS, Buick LaCrosse, Chevrolet Camaro/Equinox, GMC Terrain with LF1/LLT/LY7 engines.
- ✅ Plug & Play – Exact match in dimensions, 6-pin connector, and 4-bolt mounting pattern. Uses factory gasket (sold separately).
- ✅ Fast Response – Motor response time ≤ 50 ms for precise throttle control and smooth acceleration.
- ✅ Dual Redundant TPS – Prevents idle fluctuations, hunting, and false error codes (P0638, P0697, P2100, P2119, P2135, P1516).
- ✅ 100% Factory Tested – Thermal cycling, airtightness, and full-stroke angle calibration verified.
- ✅ ISO 16750 Compliant – Meets environmental standards for automotive electrical/electronic equipment.

IMPORTANT: After replacing the ETB on GM 3.0L/3.6L High Feature engines, a throttle self-learning / idle relearn procedure is REQUIRED. Failure to perform the relearn may result in unstable idle or check engine lights. If issues persist, use a professional diagnostic scanner (GM MDI / Tech2) to perform a “Throttle Body Relearn” or “Idle Learn”.
| Step | Action |
|---|---|
| 1 | Disconnect the negative battery terminal for 5–10 minutes (clears old learned values). |
| 2 | Remove the air intake duct and disconnect the electrical connector (6-pin). |
| 3 | Remove any coolant hoses attached to the throttle body (if equipped with throttle body heating). |
| 4 | Remove the four mounting bolts and old throttle body. |
| 5 | Discard the old gasket and clean the mating surface on the intake manifold. |
| 6 | Install a new gasket (strongly recommended – sold separately). |
| 7 | Install the new throttle body. Torque bolts to 8–10 Nm (6–7 lb-ft). |
| 8 | Reconnect coolant hoses (if equipped), electrical connector, and air intake duct. |
| 9 | Reconnect the battery. |
| 10 | Turn ignition ON (do not start engine) and wait 10 seconds. |
| 11 | Turn ignition OFF for 10 seconds. |
| 12 | Start the engine and let it idle for 5 minutes (do not touch accelerator). |
| 13 | Turn engine off for 30 seconds, then restart and drive normally. The ECU will complete adaptation automatically. |
- Pre-installation check: Inspect the throttle body for any defects. Verify the OE number and connector type (6-pin) before installation.
- Gasket requirement: A new mounting gasket is strongly recommended — gasket not included. A damaged or reused gasket may cause rough idle or check engine lights.
- Relearn requirement: A throttle relearn calibration procedure is mandatory after installation. Failure to perform the relearn may result in unstable idle or drivability issues.
- Packing List: Electronic Throttle Body Unit (72mm bore, complete assembly with TPS and motor) × 1; Warranty Card × 1. (Gasket and installation hardware not included)
