Replacement and Interchange Numbers
This assembly is marketed as a replacement for:
- Airtex AW6009
- GMB 130-9670
- Gates 45010
- GM 12587305
- GM 12600767
- GM 12681417
- GM 19208815
- GM 19253263
- ACDelco 251-713
- G9670B
Interchange numbers are useful reference points, but they do not guarantee fitment by themselves. GM used several cooling-system arrangements during this period, because apparently one water pump for every V8 would have been far too convenient.

Water Pump and Thermostat in One Package
The water pump circulates coolant through the engine, heater core, and radiator. The thermostat regulates when coolant begins flowing through the radiator based on engine temperature.
Replacing both components together can be sensible when:
- The vehicle has high mileage
- The thermostat’s service history is unknown
- The engine has overheated
- The thermostat housing is leaking
- Cooling-system contamination is present
- The system is already drained for water-pump replacement
A new pump cannot compensate for a thermostat that remains closed. Likewise, replacing the thermostat will not repair a leaking shaft seal or damaged pump bearing. Cooling systems can be annoyingly committed to teamwork.
Quality-Control Standards
The manufacturer states that its production facilities maintain ISO 9001 and IATF 16949 certification. These standards apply to quality-management systems and automotive manufacturing processes.
Certification does not mean that every part is an original GM component, nor does it independently guarantee fitment. It indicates that the factory uses documented manufacturing and quality-control procedures.
For additional context, the International Automotive Task Force provides information about the IATF 16949 automotive quality-management standard.
Professional Product Testing
The manufacturer reports that each unit undergoes quality testing using professional equipment. Proper water-pump testing helps evaluate:
- Bearing operation
- Shaft alignment
- Seal performance
- Housing integrity
- Impeller operation
- Dimensional consistency
- Coolant-flow performance
The comparable GMB 130-9670 water pump is described by GMB as being factory-tested for leakage, dimensional precision, bearing noise, and durability while matching OE coolant-flow and pressure requirements.
Symptoms of a Failing GM V8 Water Pump
A failing water pump may produce:
- Coolant leaking from the front of the engine
- Dried coolant around the pump or gasket surfaces
- Grinding or rumbling bearing noise
- Pulley wobble
- Repeated coolant loss
- Engine overheating
- Temperature fluctuations
- Weak or inconsistent cabin heat
- Steam or a coolant odor after driving
Water-pump symptoms can overlap with problems involving the thermostat, radiator, hoses, pressure cap, cooling fans, or head gaskets. Our guide comparing a bad thermostat with a bad water pump can help separate the likely causes.
If coolant is disappearing, follow our diagnostic guide explaining how to find a coolant leak before replacing parts.
Installation Recommendations
Water-pump replacement should be performed only when the engine is completely cool. Hot, pressurized coolant can cause severe burns.
A typical installation includes:
- Disconnecting the battery when required by the service manual.
- Draining the coolant into a suitable container.
- Removing the intake ducting, fan assembly, belt, hoses, and related components as necessary.
- Inspecting the belt, tensioner, idlers, fan clutch, hoses, and radiator.
- Removing the old water-pump assembly.
- Cleaning the engine’s gasket surfaces carefully.
- Comparing the new assembly with the original pump.
- Installing new seals and gaskets.
- Tightening all fasteners to the factory specification and sequence.
- Refilling with the correct GM-approved coolant.
- Bleeding trapped air from the cooling system.
- Pressure-testing the system and checking for leaks.
Do not apply sealant unless the service procedure or gasket manufacturer requires it. More sealant is not more sealing; eventually it becomes floating debris looking for a coolant passage to clog.
Use the Correct Coolant
Coolant must be compatible with the vehicle’s engine, radiator, seals, and existing fluid. Color alone does not establish compatibility.
Read our guide to IAT, OAT and HOAT coolant types before mixing or replacing coolant. If the existing fluid is contaminated or unknown, consult our guide on flushing a cooling system without causing damage.
One-Year Replacement Warranty
The product includes a stated one-year free-replacement warranty. Warranty coverage may require the original receipt, proof of proper application, and purchase through an authorized seller.
Before ordering, confirm:
- Who processes warranty claims
- Whether labor or consequential damage is excluded
- Whether return shipping is covered
- When the warranty period begins
- Whether commercial use affects coverage
Frequently Asked Questions
Does this pump fit every 2007–2019 Chevrolet or GMC V8?
No. The year range covers numerous platforms and engine combinations. Compatibility depends on the model, engine displacement, production date, VIN, and original water-pump design.
Does it fit a 2014–2019 Silverado 1500 with a 5.3L EcoTec3 engine?
Do not assume that it does. The redesigned K2XX Silverado 1500 uses later Gen V EcoTec3 engines and may require a different pump. The 2007–2013 Silverado 1500 represents the most common AW6009-style light-duty pickup application.
Why does the listing extend through 2019?
The later applications primarily involve vehicles such as the Chevrolet Express, GMC Savana, and certain heavy-duty Silverado and Sierra models that continued using compatible 4.8L or 6.0L V8 engine families.
Does this fit the 6.6L Duramax diesel?
No. This pump is intended for selected gasoline or flex-fuel GM V8 engines. A Duramax diesel uses a different water pump and installation procedure.
Is the thermostat included?
Yes. This package is advertised as a water-pump assembly supplied with a thermostat. Confirm the package contents when it arrives and before beginning installation.
What is the difference between AW6009 and 130-9670?
AW6009 is an Airtex reference, while 130-9670 identifies a GMB replacement pump. Both are commonly used as interchange references for this GM V8 water-pump design.
Can a failing water pump cause overheating only while driving?
Yes. A worn impeller, slipping drive, restricted flow, or coolant loss can become more apparent under load. However, radiator restriction, low coolant, airflow trouble, or combustion leakage can cause similar behavior. Review our guide to diagnosing a vehicle that overheats while driving.
Final Verdict
This water-pump and thermostat package offers a convenient replacement for numerous GM trucks, SUVs, and vans using compatible 4.8L, 5.3L, and 6.0L V8 engines. Its broad interchange coverage, combined thermostat, reported quality-control testing, and one-year replacement warranty make it worth considering for a properly verified application.
Fitment verification remains essential. Match the original pump number and confirm the VIN before ordering, particularly on 2007 and 2014 transition-year vehicles.
