Counterfeit vs Real OEM Toyota Prius Inverter Pump 04000-32528

Thank you, while I know not "counterfeit" the part sold at O Reilly's failed in under one year for me. They did refund all my money, but it was a huge hassle to replace for the second time in a year.

Don't be deceived by eBay sellers offering counterfeit "Genuine" Toyota Prius Inverter Pump 04000-32528. Read below and study the pictures on this listing to learn how to tell before and after buying a 2004-2009 Prius Inverter Coolant Pump if it is an authentic OEM part or a lower quality, less reliable Chinese made knock-off.

Toyota Part 04000-32528 is a kit which should include two parts: 1) inverter coolant pump G9020-47031 and 2) inverter coolant gasket 90430-18008.

An authentic OEM part 4000-32528 (manufactured by the Japanese company Aisin) has printed circles and letters on the outside of the part. Counterfeit or knock off parts are missing these printed markings on the outside of the part.

An authentic OEM part 4000-32528 contains a pump plus an inverter drain plug gasket as per Toyota documentation. Low cost knock-offs and counterfeit “genuine” part 4000-32528 may not include the vital drain plug gasket in the package.

An authentic OEM inverter pump has a phillips head set screw visible from the top. Non OEM pumps use a different type of screw, usually with a hex head. You can expect the low cost knock offs and counterfeit “genuine” parts to skimp on all the internal materials and seals vital to preventing the electric pump motor from failing.

An authentic OEM part 4000-32528 always comes with a silver steel mounting base. Non OEM pumps might come with a silver or brass colored base. If the base is not silver then the pump is not OEM.

The OEM inverter pump does not have caps on the pump ports. Listings of pumps with white caps are not OEM. eBay listings claiming to be “genuine” Toyota parts that have pumps with white caps are counterfeit.

Authentic Toyota OEM part labels have a barcode that scans to read “0400032528E" which is the Toyota part number for this item. A counterfeit label has a barcode that scans to read a string of miscellaneous/random numbers. You can download a barcode scanner on your smartphone to read the number the barcode represents. If it doesn't read to be the appropriate Toyota part number then it's counterfeit. The counterfeit part label in the photo has a barcode that reads "123456781445614646564” which is nonsense.

Authentic Toyota OEM labels have coded information printed in black ink on the bottom right of the label. This is present on all genuine Toyota part labels. These codes are absent on counterfeit Toyota labels. A simple review of eBay listings claiming to be “genuine” Toyota parts that have labels lacking this imprinted information are likely counterfeit. A scan of the barcode would confirm that part is counterfeit if the bar code does not equal the Toyota part number.

Authentic Toyota OEM inverter coolant pumps last around 100,000 – 150,000 miles. Authentic Toyota parts don’t come with warranties beyond 1 year. Other listings with multi-year warranties are suspect. You can bet the seller with a multi year warranty will be long gone when your cheap pumps fails a few months after you installed it (or worse yet paid someone else to install it).

A low quality knock off inverter coolant pump sells for around $30-50. eBay sellers buy these cheap pumps from China for about $20. A counterfeit “Genuine” Toyota inverter coolant pump sell for around $50-75 on ebay . . . a fair price. Dealer price will be $120-200. The life span of a counterfeit part or low cost knock off will not be as long at an authentic OEM inverter pump.

It’s OK to buy a low cost pump if that's what you want . . . it will work. Just don’t get fooled thinking you scored a deal buying a low cost “Genuine” part that is in fact a lower quality counterfeit.

Give some thought to what the cost and experience was like when your Prius inverter coolant pump failed on you recently. How soon would you like to repeat that? How close to home will you be when it happens again? How safe will the area be when your inverter coolant pump fails? What are the consequences of being delayed to your destination when your low quality Chinese inverter coolant pump fails? How much damage to your expensive inverter will be sustained by continuing to drive with a failed inverter coolant pump when it fails miles away from home? How much will it cost you in the long run to save a few bucks now on a low quality, less reliable knock-off or counterfeit “Genuine” inverter coolant pump?

Hope you get a genuine Toyota part. I have heard that ebay can have counterfeits.

I always get parts from the local brick & mortar Toyota dealer. Zero problems that way.
