Beware fake AISIN engine coolant water pumps!

A shop or person with less experience than me, may buy one of these... for a normal price... and be none the wiser. The box it comes in is 99% like the original.

It's actually nicer packed than OEM, with foam and bubblewrap, with the gasket preinstalled. What raised my suspicion, was the fact that the Toyota logo WASN'T sanded off.

Do note: you can find these illegal counterfeits in Toyota dealership boxes too.

Opening it revealed the circuit board, of much lower quality, lacking the AISIN branding.

These WPT-190 pumps are made in Japan. My recommendation is to only buy them from sellers based in Japan. (or the Toyota dealer if you're OK with the $100+ markup) There are legit Japanese sellers on Amazon and eBay... There's also lots of Chinese knockoffs.

Even if you buy from a reputable place, do inspect it carefully, because a bad batch could end up in a legitimate seller's hands.

UPDATE: Need help from Prius Owners

So, I ended up listening to some of your advice, and took the car to a trusted mechanic. We checked the engine bay, and undercarriage. Mechanic told me that the car's in decent condition. At the same time, the dealer informed me that he will fix the abs sensors, and some of the other issues I pointed out. I don't think the headgasket has given out yet, so I'm guessing that's a problem for the future.
A lot of people pointed out how the gen 3's are the least reliable amongst the priuses, so that has me worried a little. But, with these developments, do you guys suggest I go through with this purchase if the dealer fixes said issues?

Did my mechanic lie to me? (2026 Prius PHEV cooling)

2026 Black Toyota Prius Plug-In Hybrid XSE

I've had my Prius for about 13 months now. I was watching a YouTube video about the fact that the Prius has a fan with a filter under the rear seat that needs to be cleaned. I checked under my rear seat and was surprised I didn't find it, I then learned that plug-in hybrids use a liquid cooling system for their battery instead of the fan.

A few months later (about 2 days ago) I went in for the 20,000 mile maintenance check and the mechanic wanted to charge me $181 to clean the hybrid fan. I declined the charge and told them that it's a plug-in hybrid so it's liquid cooled.

He said to me that " your car still has the fan but it doesn't have the filter" he said I don't need to do it now but they want to clean it later. That doesn't make any sense to me lol if there is a fan somewhere, where is it and where is the air blowing out?

I'm pretty sure I just caught him in a lie and he couldn't admit it but maybe there is something I'm missing, does the plug-in hybrid system have a fan of some sort somewhere else that needs to be cleaned regularly?

Gen 2 Prius 50MPH+ rough running. Timing chain?

Hi, I have a 2007 Prius touring with 201K miles. Over the last year I've thrown parts at it and I've gotten it to run better but it still feels like the engine struggles over 50mph. It gets about 42-45 mpg when kept at about 50-55. But once I hop on the freeway anything above 60mph and MPG drops to low to mid 30s. The motor doesnt seem to settle down into the right gear to maintain 65-70. I was just visiting my mom and she has a 2006 with 165K miles and I drove it on the freeway and it is so much smoother and the balance between electric motor and gas engine is great. My car engine sounds louder and I can feel a slight vibration in the accelerator.

My prius has new plugs, coils, injectors, MAS air sensor, throttle body, VVT solenoid and CAT. I've unplugged the battery and reset the ECU after any time I've worked on the car. It doesn't throw any codes but I wonder if the timing chain is stretch or the tensioner is maxed. Or is the VVT system not fucioninng properly. Is there any way to test or check without removing valve covers and really getting in there. could any sort of diagnostic tool test or check this?

Prius V scratches

I bought a 2017 Prius V a couple of weeks ago (I absolutely love it). When I bought the vehicle the paint was super clean. Somehow in the last two weeks it has a ton of scratches on the hood..? I don't park under acorns, and don't put crap on my hood so i,m baffled as to how they got there..

Anyhow, they're here now and I'm curious how I should go about dealing with it. Do we think Icould buff them out, or will I need to have the entire hood repainted? Alternatively I could just leave it (definitely not the route i want to go) would this be any concern for rust?

Any advice is appreciated!

Thanks!

going to attempt the head gasket on my 2010 prius, what tools, parts, etc. do i need and any advice?

made a post awhile ago asking about whether the coolant disappearing + knocking in my 2010 prius was my head gasket; i’m pretty sure it is, i’ve included a pic of the inside of my second cylinder for reference.

i was hoping to last it out a little longer to make it until i didn’t need my car for a couple of days, but i got the engine overheating light on my way to work today so i think i need to do it ASAP.

i have a socket wrench and up to 14 mm sockets, the one video i glanced at said i would also need a 19 mm, but what other tools do i need to have to get the job done? also, what parts do i need to get? i have almost no mechanic experience but i was able to scope inside the cylinders so i’m confident that with the right tools, guide, and enough time i can get the job done.

Another high mileage 3rd gen

So as the title and flair suggests, I am looking at buying a Prius. I found this one that seems to have had some work done to hedge against the notorious head gasket issues I’ve read about, but my question is if anyone has experience with doing these maintenance items and seeing a significant increase in HG life span?

I have never owned Prius and I’m just now really starting to learn the ins and outs of this vehicle, so any advice would be greatly appreciated.

Also, just as a general gut check, does this seem like a fair price range from the hive mind? Located in East Tennessee. From what I’ve been looking at this really doesn’t seem outlandish, but again, I have pretty limited knowledge of these things.

Thanks all!

Gen 2 Prius not starting, but dash lights up

Everything lights up (including the triangle of death) and the windows move a lot slower. It takes about 20-40 tries to get it to turn over, and it usually results in some ritual of opening and closing my door until it comes back to life... It's a new 12v battery too. Always starts with a jump however. Any ideas on what's going on?

Any metro Vancouver drivers in here ? I have a daily commute over 50 km from east Coquitlam to south Burnaby. I’m looking to buy either a 2027 Prius plug in SE or the XLE AWD Prius.

I’m looking for specific feedback on anyone commuting in a colder climate with the Prius plug in , do you wish you had AWD ?
I’m driving a 2008 Yaris outfitted with steel wheels and Blizzak WS 90 . I would put winters on steel wheels on either Prius I buy .
I have test driven both models back to back, I preferred the plug in to drive the AWD was noisy, louder than my wife’s 2020 Corolla LE ! The plug in was much quieter and i enjoyed the driving experience better I felt I was in a premium car.
The AWD felt like any other Toyota Corolla !
I can plug in overnight , not sure if real world results I will get better gas mileage with the plug in ! I do a few trips a year up to the interior.
I don’t want to regret buying one over the other.
