Replacement and Interchange Numbers
This pump is advertised as a replacement for:
- 16032-25010
- 1603225010
- 16032-F0010
- 16032F0010
- 16032-F0011
- 16032F0011
- 16032-F0012
- 16032F0012
These numbers may represent superseded or related Toyota pump assemblies, but an interchange number is not a universal-fit coupon. Match the number on the removed pump and verify the application by VIN before installation.
What the Electric Water Pump Does
The water pump circulates coolant through the engine and cooling system, carrying combustion heat toward the radiator. Because this pump is electrically driven, its speed can be controlled according to operating conditions instead of being tied directly to engine RPM.
Proper coolant circulation helps:
- Control engine temperature
- Reduce localized hot spots
- Move heat into the radiator
- Support consistent heater performance
- Protect the engine during idle and low-speed operation
For a broader explanation of pump and thermostat symptoms, read our bad thermostat versus bad water pump guide.
Common Signs of Electric Water-Pump Failure
A failing electric coolant pump may cause:
- Engine overheating
- Intermittent temperature increases
- Reduced or inconsistent coolant circulation
- Cooling-system or water-pump fault codes
- Warning messages or reduced-power operation
- Coolant leakage around the pump housing
- Unusual electrical or mechanical pump noise
- Weak cabin heat when circulation is severely reduced
These symptoms do not automatically condemn the pump. Low coolant, trapped air, a faulty temperature sensor, damaged wiring, a restricted radiator or thermostat trouble can produce similar results.
If coolant is disappearing, follow our step-by-step coolant-leak diagnosis before launching the parts cannon.
Product Features
- Preassembled electric engine-coolant water pump
- Direct-replacement housing configuration
- OE-reference number 16032-25010
- Vehicle-specific electrical connector
- Designed for select Toyota 2.5L applications
- Manufactured under the seller’s stated IATF 16949 quality-management standard
- One pump assembly included
The IATF explains that IATF 16949 establishes automotive quality-management-system requirements. Certification describes the manufacturing system; it does not eliminate the need to verify the individual part’s fitment or warranty.
Installation Considerations
Installation should include more than removing one pump and bolting in another.
Before fitting the replacement:
- Allow the vehicle and coolant to cool completely.
- Disconnect the 12-volt battery according to Toyota service procedures.
- Confirm that the replacement connector and mounting points match.
- Inspect the wiring harness for heat damage, corrosion or damaged terminals.
- Use the Toyota-specified coolant.
- Refill and bleed the cooling system using the correct vehicle-specific procedure.
- Check for leaks and verify pump operation with a compatible scan tool.
- Confirm that coolant temperature stabilizes during the final road test.
Hybrid vehicles contain high-voltage systems. The orange high-voltage wiring is not an invitation to explore. Follow Toyota service information or have a qualified hybrid technician perform the repair.
If contaminated or incompatible coolant is present, consult our guide to flushing a cooling system safely. Our coolant-type guide also explains why selecting antifreeze by color alone is unreliable.
What Is Included?
The package contains:
- One preassembled electric engine-coolant water-pump unit
Unless specifically shown in the product package, coolant, mounting hardware, external hoses and service tools are not included.
Buyer Verification Checklist
Before ordering, verify:
- Year, make and model
- 2.5L engine application
- Hybrid or gasoline configuration
- VIN and engine code
- OE number on the original pump
- Connector orientation
- Bolt pattern and mounting points
- Included seals or gaskets
- Seller warranty terms
Frequently Asked Questions
Does 16032-25010 fit every 2.5L Toyota Camry?
No. This listing specifically identifies the 2018–2020 Camry Hybrid with the AXVH70 chassis code. Confirm the original pump number before ordering for a gasoline-only Camry.
Does this pump fit the Toyota RAV4 Hybrid?
It is listed for select 2019–2022 RAV4 2.5L applications, including certain hybrid models. Because Toyota used multiple powertrain configurations, verify the VIN and original pump number.
Is this a belt-driven water pump?
No. It is an electrically driven coolant pump.
Does the package include coolant?
No. The package contains one water-pump assembly. Purchase the exact Toyota-specified coolant separately.
Must the cooling system be bled after installation?
Yes. Air trapped in the cooling system can reduce circulation, eliminate cabin heat and cause overheating even when the new pump works correctly.
Can a bad electric water pump trigger a warning code?
Yes. Electrical, control-circuit or performance problems can generate diagnostic trouble codes. Read the codes and test power, ground, wiring and commanded pump operation before replacing parts.
