OEM or AM part for Aux Cooling Pump Heater?

It's not a very serious designed pump I use this pump in several places in various other things the coolant heat storage tank pump from the generation 2 Prius I'm talking about I have several here You can probably go snag one at LKQ and pay $25 or 30 bucks for it they don't really go bad that often so I would say try to make that happen I would hate to have to pay a hundred or 200 bucks for one but if that's what you have to do that's what you have to do are you doing this because the CHS tank code or do you know it to be bad You can hear it when you start the car up in the morning and after you shut the car off 5 hours on the nose it should come on again to sample the water You can be standing there at the wheel well at 4 minutes and 4 hours rather and 50 minutes and just wait a few and hear it come on just curious?.

Based on the above, this "may" be the Toyota number:

G9020-47031

^ Lots of much cheaper offerings with that part number in the description, on Amazon, for what it's worth.

The US Toyota Parts site you linked also has it:

The Toyota number I have off the label is 16290-21011 It's a 12 volt pump and I'm holding two of them and they both have the same number and they're both 12 volts I would say given the design of the pump it's pretty well used in other things not Toyotas only not the nip and denzo brand but the design of the pump all the way down to the power plug so you could probably use a non Toyota replacement that will plug in and work and all that I don't think it will be like the inverter pump hullabaloo at all me personally I would just run and grab one from the junkyard that's LKQ they're real big out east here in in the States

 

Doesn't say where you are in your cig I'd be happy to send you one I'm getting ready to take off two or three more and dismantling a couple of cars over the next few days they're sitting right here at my place of course unless it's to India or something

The Coolant Heat Storage tank is a thermos that holds several quarts of coolant & keeps it hot for a few days. The pump fills the tank when you shut off then pumps the (still) hot coolant into the engine when you start the car.

It's there to reduce warmup emissions & has no real effect on driveability. Mine "squalled" at me for a couple of years before I got tired of the noise, then replaced it. If it fails the ECM will set codes and turn on the check engine light.

It's up to you which part to use. I always prefer OE from Toyota as the most reliable. I have had decades of poor results from most aftermarket parts - esp Dorman (it's the brand "of last resort").

BUT that pump gets very little use, so Dorman MIGHT be good enough? (maybe?)

For a coolant heat storage tank pump in your Prius, going with an OEM part is generally recommended to ensure the highest quality and compatibility, especially for something that plays a key role in the cooling and hybrid system. OEM parts tend to have a longer lifespan, and you can trust that they meet the exact specifications needed for your vehicle.

That said, the Dorman part you mentioned could still be a viable option if you're looking to save money. Dorman is known for offering aftermarket parts that are often less expensive but still meet functional standards. However, when using aftermarket parts, there is always a slight risk that the fit or longevity might not be as perfect as the OEM version.

If you're not planning on keeping the car for much longer, the Dorman part could be a cost-effective choice. But if you want peace of mind and long-term reliability, sticking with the OEM part may be worth the extra cost. It also helps to read reviews and check any warranty offered by the aftermarket part to assess its reliability.

 

Or just buy one from off of a car like at copart or LKQ the pumps like this you're going to want to keep there's no need to change them to another type of pump. And you should be able to even buy some at lesser cost than the dorman that shouldn't be a serious problem If they're that cheap buy 2 and see what happens The design of this pump is not like the pancake inverter pump which is a completely different design and I can see where it can be made cheap enough to fail relatively quickly easily but this other pump for the CHS tank and the one between the brake booster pieces they are completely different design I use this design on spa circulation and things like that almost the same exact design pump and the Chinese cheap ones tend to do quite well so far I don't personally have one mounted on a Prius right now but I have them on a bunch of other things and I could put one on a Prius I just don't have the need to change a CHS pump at the moment and I have several off other cars that have come here to completely die and be junked.
