Engine Fitment
Potential compatible engines include select versions of:
- 4.8-liter Vortec V8
- 5.3-liter Vortec V8
- 6.0-liter Vortec V8
- 6.2-liter V8 where specifically cataloged
Do not assume compatibility with:
- 2.9-liter four-cylinder
- 3.7-liter inline-five
- 4.2-liter inline-six
- 4.3-liter V6
- 6.6-liter Duramax diesel
- Hybrid powertrains
- Engine-swapped vehicles
Matching displacement alone is not enough. GM used multiple starters across related engines and vehicle platforms.
Tahoe Fitment Warning
The title advertises 4.8L and 5.3L Tahoe fitment for 2009–2014, but the specific engine offered can vary by year, market and fleet configuration.
Before listing or ordering, verify:
- Model year
- Engine displacement
- Eighth VIN character
- Two- or four-wheel drive
- Original starter number
- Production date
Do not assume every Tahoe within the year range uses this starter simply because it contains a V8.
Silverado and Sierra Fitment
Advertised pickup applications include:
- 2009–2013 Chevrolet Silverado 1500
- 2009–2013 GMC Sierra 1500
Verify compatibility with:
- 4.8L V8
- 5.3L V8
- 6.0L V8
- 6.2L V8
- Flex-fuel configuration
- Two- or four-wheel drive
- Automatic transmission
- Factory towing or payload package
Do not automatically list this unit for:
- Silverado or Sierra Hybrid
- 1500HD
- 2500HD
- 3500HD
- Duramax diesel
- 2014 new-generation Silverado or Sierra
- Earlier GMT800 trucks
Express and Savana Fitment
The starter is advertised for select:
- 2008–2017 Chevrolet Express 2500
- 2008–2017 Chevrolet Express 3500
- 2008–2017 GMC Savana 2500
- 2008–2017 GMC Savana 3500
These vans were available with several gasoline and diesel engines. Confirm:
- Engine displacement
- Gasoline or diesel configuration
- Gross vehicle weight rating
- Transmission
- Production date
- Original starter number
Do not list the 6970 starter for Duramax-powered vans unless the complete interchange catalog specifically confirms it.
Colorado and Canyon V8 Fitment
The Chevrolet Colorado and GMC Canyon applications should be restricted to compatible V8 models:
- 2009–2012 Chevrolet Colorado 5.3L V8
- 2009–2012 GMC Canyon 5.3L V8
Do not assume fitment for four-cylinder or inline-five versions. Same pickup bed, dramatically different object bolted to the transmission.
Suburban and Yukon XL Fitment
Suburban and Yukon XL models require additional chassis verification because 1500- and 2500-series vehicles may use different engines and starting systems.
Confirm:
- 1500 or 2500 series
- Engine displacement
- Original GM number
- Gasoline or diesel fuel
- Transmission
- VIN engine code
Hybrid applications are not confirmed.
Replacement Part Numbers
This starter may replace or cross-reference:
69706970N323-1655323-1662410-12377800021580002941261110219168041191805292865519-18-0529
The most important OE references in the supplied title are:
- GM 12611102
- GM 19168041
Match the complete number on the original starter whenever possible.
Expected Starter Specifications
Based on the common 6970 interchange, the expected configuration is:
| Specification | Expected value |
|---|---|
| Voltage | 12 volts |
| Rated output | Approximately 1.4 kW |
| Pinion teeth | 9 |
| Rotation | Clockwise |
| Condition | New |
The current listing does not explicitly provide these electrical specifications. Confirm them on the product label or technical drawing before publication.
Fitment Verification
Before ordering, compare:
- Original starter number
- Engine code
- Mounting flange
- Bolt-hole spacing
- Starter nose length
- Pinion tooth count
- Pinion resting position
- Solenoid location
- Battery-terminal position
- Trigger-terminal design
- Bellhousing clearance
- Exhaust clearance
The NHTSA VIN decoder can help identify the vehicle and engine, but the original starter should still be inspected.
New Replacement Construction
The manufacturer states that the starter is assembled using new premium components intended to meet or exceed original-equipment specifications.
Potential benefits of new construction include:
- New armature and windings
- New brushes and bearings
- New starter drive
- New solenoid components
- No reused internal wear surfaces
- Consistent housing condition
“Meets or exceeds OEM specifications” should remain identified as a manufacturer claim unless independent test documentation is available.
Manufacturing Certifications
The manufacturer states that its factory:
- Obtained ISO/TS 16949 certification in 2008
- Later transitioned to IATF 16949:2016
- Implemented Ford’s VRT quality-management process
These certifications relate to factory quality-management systems. They do not independently confirm vehicle fitment or performance for every starter produced.
Also, the correct certification abbreviation is IATF 16949, not “IAFT 16949.”
Diagnosing Starter Failure
Common signs of starter trouble include:
- Single click with no crank
- Rapid clicking
- Slow cranking
- Intermittent no-crank
- Starter spinning without engaging
- Grinding during startup
- Burning odor
- Excessive current draw
Similar symptoms may be caused by:
- Weak battery
- Loose battery terminals
- Corroded positive cable
- Poor engine ground
- Faulty starter relay
- Ignition-switch problem
- Transmission range-switch fault
- Immobilizer issue
- Damaged flexplate teeth
- Internal engine problem
Test the battery and starter circuit before replacing the motor. A new starter cannot repair a cable that has quietly become an electrical resistor.
Battery and Voltage-Drop Tests
Before replacement, inspect:
- Battery open-circuit voltage
- Battery load-test result
- Positive-cable voltage drop
- Negative-cable voltage drop
- Starter-trigger voltage
- Battery-terminal condition
- Engine-to-chassis ground
- Starter relay and fuses
A voltage-drop test performed while cranking is more useful than checking cable resistance with the circuit unloaded.
Installation Preparation
Before removing the original starter:
- Confirm the vehicle, year and engine.
- Check the VIN engine code.
- Record the original starter number.
- Disconnect the negative battery cable.
- Photograph the electrical connections.
- Compare the mounting flange and pinion.
- Obtain the correct torque specifications.
- Confirm whether mounting hardware is included.
The supplied listing does not state that mounting bolts are included.
Installation Overview
A typical replacement includes:
- Disconnecting the negative battery terminal.
- Raising and safely supporting the vehicle if required.
- Removing shields or braces that obstruct access.
- Labeling the starter wires.
- Disconnecting the battery cable and trigger wire.
- Supporting the starter.
- Removing the mounting bolts.
- Comparing the original and replacement units.
- Inspecting accessible flexplate teeth.
- Installing the new starter.
- Torquing the mounting bolts correctly.
- Reconnecting the electrical terminals.
- Securing wiring away from exhaust components.
- Reinstalling shields and braces.
- Reconnecting the battery and testing operation.
Disconnecting the battery is mandatory. The unfused starter cable is perfectly capable of turning a ratchet into a space heater.
Two-Year Warranty
The manufacturer advertises a two-year warranty.
Before purchasing, confirm:
- Warranty start date
- Proof-of-purchase requirements
- Labor reimbursement
- Return-shipping responsibility
- Diagnostic documentation
- Commercial-use exclusions
- Consequential-damage coverage
- Replacement processing time
Warranty length does not replace correct vehicle and engine verification.
Frequently Asked Questions

Final Verdict
The 6970 starter provides a new replacement option for a broad group of GM V8 trucks, SUVs and vans. Its interchange with GM numbers 12611102 and 19168041 offers the most reliable starting point for fitment confirmation.
The broad title requires careful editing. Limit Colorado and Canyon applications to compatible V8 models, separate Express and Savana gasoline engines from diesels and verify the chassis series on Suburban and Yukon XL models. Engine, VIN and original starter-number confirmation remain essential.
