Chevrolet Sonic Engine Requirement
The Sonic was available with both 1.4L turbo and 1.8L naturally aspirated engines. AW6662 is for the 1.4L turbo only.
Apparently ordering by year and model wasn’t sufficiently exciting, so GM added two engines that use different pumps.
Engine and VIN Information
Many compatible applications use the GM LUV 1.4L turbocharged engine, frequently identified by VIN code B. Engine codes and emissions configurations can vary, so verify:
- VIN engine digit
- Engine code
- Original pump number
- Pulley alignment
- Mounting pattern
- Housing and hose arrangement

Product Features
Direct-Replacement Design
The pump is designed to match the factory mounting pattern, pulley position and coolant passages on compatible GM 1.4L engines. No modification should be required when the correct application is selected.
Metal Impeller
The metal impeller is designed to maintain factory-style coolant circulation through the engine. Impeller shape and clearance matter more than vague “high-flow” marketing language; coolant pumps are hydraulic components, not motivational posters.
Sealed Bearing Assembly
The internal bearing supports the pump shaft and pulley while the engine runs. A sealed and properly lubricated bearing helps control shaft movement, noise and premature mechanical-seal wear.
Unitized Seal
The pump’s internal seal separates engine coolant from the bearing assembly. The manufacturer states that the completed pump is tested for leak-resistant operation before shipment.
“Leak-free” should be treated as a manufacturing goal, not a lifetime guarantee. Every mechanical seal eventually answers to heat, contaminated coolant and physics.
What Does the AW6662 Water Pump Do?
The engine’s serpentine belt rotates the pump pulley and impeller. The impeller circulates coolant through the cylinder block, cylinder head, heater core and radiator.
Proper circulation helps:
- Regulate engine temperature
- Remove heat from the cylinder head
- Supply heated coolant to the cabin heater
- Carry engine heat to the radiator
- Reduce localized hot spots
- Maintain consistent temperature under load
Read our bad thermostat versus bad water pump guide if the cause of overheating has not been confirmed.
Common Signs of Water-Pump Failure
- Coolant leaking near the pump
- Dried coolant residue around the housing
- Leakage from the pump’s weep hole
- Grinding or growling bearing noise
- Pulley wobble or shaft movement
- Serpentine-belt tracking problems
- Repeated low-coolant warnings
- Engine overheating
- Weak heater output combined with rising temperature
A failing thermostat housing, cracked coolant outlet or leaking hose can produce similar symptoms on the GM 1.4L engine. Follow our coolant-leak diagnostic guide before replacing parts.
Will AW6662 Fix an Overheating Engine?
Only if a failed water pump is causing insufficient coolant circulation.
Other possible causes include:
- Low coolant
- Air trapped in the system
- Cracked thermostat housing
- Stuck thermostat
- Radiator restriction
- Cooling-fan failure
- Faulty coolant-temperature sensor
- Coolant leaking from the turbocharger circuit
- Cylinder-head or head-gasket damage
Diagnose the system before installing a pump based solely on an overheating complaint. The parts cannon has excellent recoil and terrible accuracy.
Installation Recommendations
- Confirm the engine is the compatible 1.4L turbo.
- Compare the new pump with the original assembly.
- Allow the engine to cool completely.
- Disconnect the negative battery cable.
- Drain the coolant into a suitable container.
- Remove interfering components according to service information.
- Release the serpentine belt.
- Inspect the belt, tensioner and idlers.
- Remove all old gasket material.
- Install the new gasket without excessive sealant.
- Torque the pump fasteners to GM specifications.
- Reinstall and route the belt correctly.
- Refill with the specified coolant.
- Bleed trapped air from the system.
- Pressure-test for leaks.
- Confirm stable operating temperature.
Never open the coolant reservoir while the system is hot or pressurized.
For contaminated or mixed coolant, consult our cooling-system flushing guide. Our coolant-types guide explains why antifreeze should be selected by specification rather than color.
Frequently Asked Questions
What vehicles does AW6662 fit?
It fits select 2013–2020 Buick Encore, 2011–2015 Chevrolet Cruze, 2016 Cruze Limited, 2012–2020 Chevrolet Sonic and 2013–2020 Chevrolet Trax models with the 1.4L turbo engine.
Does AW6662 fit a 2016 Chevrolet Cruze?
It fits the 2016 Cruze Limited with the first-generation 1.4L turbo engine. It should not be assumed to fit the redesigned second-generation Cruze.
Does it fit a Chevrolet Sonic with the 1.8L engine?
No. This pump is for the compatible 1.4L turbo engine.
Does it fit a 2013 Trax in the United States?
The Trax did not officially reach the U.S. market until the 2015 model year. Earlier 2013–2014 fitment refers to Canadian and other markets.
Is the thermostat included?
No. This listing is for the water pump and its installation gasket. The thermostat and thermostat housing are separate components.
Are AW6662 and 130-2140 the same reference?
They are common aftermarket interchanges for the same application family. Always compare the pump and original OE number before installation.
Is AW6662 an electric water pump?
No. It is a belt-driven mechanical water pump.
Does the pump fit every Buick Encore through 2020?
Only compatible 1.4L applications with the matching pump configuration. Verify the VIN, engine code and original part number.
