Check the price on Amazon for the Aisan pump. LAst time I looked it was about $250. With labor, megabucks.

You were on borrowed time at 188k. Thank God everyday for your luck.

[@igorrosales1799]

Hi man but how did you know that you needed to replace it? (The water pump). I have the “check hybrid system” message and I don’t know if the problem is the water pump

[@VibnWavez]

@@amazoidal Heh, I'm at 178k and I bought the car with right around 100k so I have to assume it's never been done but possibly. I should probably do it. No codes but I have seen the red temp light blip randomly a few times in the past and that's scary. Ironically it was cold out when it did that.

Damn that was fast and straightforward. Was wondering, “how long will this take?”. Apparently under 7 minutes ;) Super clear and helpful. Thanks guys!

[@AbidAli-rc7pm]

Hello sir I'm very happy to see your videos you are very good mechanic and I like your work you are the best god bless you and your family amen 🙏🙏

[@amazoidal]

The GEN 3 electric water pump is made by AISAN but is a little weak and has plastic parts that break from the heating and cooling cycles. Specifically the impeller and a plastic "ring" that cracks and then jams the impeller. If you see the dash light up it is too late. The head gasket is already toast. While the GEN 2 water pump is an old fashioned belt driven water pump, it costs about $35 instead of $250 and can last over 200k. If you are smart, buy a new water pump on Amazon (Aisan) and replace the old one at 100k. The 2010 - 2012 already have weak head gaskets. The GEN 4 head and gasket were redesigned and have way fewer problems in the head gasket dept. Some owners have even replaced their engines with GEN 4 because many owners don't want to take a chance with the GEN 3 "Time-bomb". Gasket Masters does a crapload of GEN 3 head gaskets but few GEN 2 or GEN 4. Tells the story right there.

[@Greg-re7tr]

If Prius owners want to replace it BEFORE it fails or before coolant starts leaking, I've heard on priuschat anywhere from 120K to 180K to 200K. However I'm at 232K miles 2013 Prius and my water pump is still good but I'm planning to replace it very soon because mechanic said I should replace thermostat and it's suggested you always want to replace both at same time. Worse case scenario I guess is if the plastic water pump impeller fails, no coolant moving, engine would overheat but ECU computer is supposed to put engine into turtle/limp mode which then one would need a tow. Some signs before it fails is if there is resistance and it doesn't spin freely, or coolant leaking, or buzzing sound is louder. Inverter pump may last longer, but also you can consider replacing that ahead of time maybe.

[@joeallen2286]

to my knowledge the issue with poor water pumps didn't carry over to the 2012+ models, however; at 200K+ the money invested to ensure the stability of your operating temperatures is compounding. It almost always costs more at the moment of unexpected failure than planning to maintain.

[@amazoidal]

The GEN 2 water pumps are cheap to replace and last 200k. It's the GEN 3 electric water pumps that jam up. The 2010-2012 had weak head gaskets.

[@Greg-re7tr]

@@amazoidal I'm planning on replacing my electric pump soon. Fluid is still flowing in tank. 2013 with 296K. some people knowingly are waiting till it fails to deal with it. I suspect by then there could be damage to the inverter unless the system turns itself off before over heating. I need to do this replacement before that happens. surprised it's still running this long. Update: I replaced the inverter pump but it was very very difficult. Took me 14 hours because of how difficult it was to bend the metal bracket to allow removal from below and that was with taking the headlight off. I would think it would be easier to remove from the top but not sure if removing the inverter and the plate under it is necessary and how difficult that would be?

[@HendroitI]

What are the signs of a bad water pump on a prius? Does it trip a dtc, does it make noise or will the engine overheat? Do they fail often? Are head gasket leaks common on the 2zr-fxe? Love the videos, very well explained

[@gasketmasters]

Hendrik de Vries they’ll trip “over revolution” code. You may hear a buzzing from the water pump louder than usual. Yes. They definitely fail a lot. Usually between 120-180k miles. We do about 300 2ZR head gaskets a year.

[@HendroitI]

Gasket Masters thanks for the reply! Do you have experience with the p3000 code and p0a0d? My car still drives perfectly and i dont know why it has set these codes

Check the ground wires on front of valve cover if you already checked the orange fuse on hybrid battery.

[@inthewoods5640]

I have a 2012 Prius with nearly 300,000 miles .I was considering pulling ahead and changing the rings Due to oil consumption issues. My question is can I pull the head and pop the Pistons out with the block still within the car Or do I need to remove the block and put it on a engine stand? Thanks for all the great videos !

[@gasketmasters]

Jayson Zimmerman yes you can. You need to remove the oil pan, and oil pump in order to do it. However, the most common reason for oil consumption is the crappy PCV valve. It is placed horizontally, instead of vertically. It is right behind the intake manifold.

[@rondhole]

Did you fix it by getting new cylinder ring or just Pvc valve? Anyone know how long typically water pump last? Most engine older engine last about 120k miles

[@amazoidal]

Get a new OEM PCV valve and then add a Catch-Can.

[@renmedia]

So if you are doing the head gasket that means that having a good water pump will not steer you away from head gasket problem?

[@napynap]

I have 2010 3rd gen Prius. Whenever the engine starts it violently shakes unless I apply some gas to warm it up somehow. Then it's fine. However, now I lost cabin heat and the engine overheat light came on after driving for a while. I can hear the loud noise near where the container for the water reservoir is. I suspect the water pump is no longer pumping. Does this sound typical of a bad water pump?

[@gasketmasters]

Loss of cabin heat is from losing coolant or exhaust gases in cooling system. Check reservoir on passenger side engine compartment.

[@napynap]

@@gasketmasters Thanks for the reply. At one point the reservoir was empty. However, when I refilled it, it would stay at full while the engine over heat light would come on and still no cabin heat. It's like the system knows the engine is hot which is why the light came on, and it's sending electric to the pump, but water is not moving through the system. The noise near pump is loud. I'm thinking that impeller assembly in the pump is broken and making that noise.

[@napynap]

Update, I replaced the water pump by following this video and I'm no longer seeing the overheat light come on. Also, I have cabin heat. The only thing different I did was to drain the fluid from the radiator by removing the bottom hose. A lot comes out, so I had to use a small tub like oil catcher. That made it easier to do. Thanks for the video and reply Gasket Masters!

@@iwontreplybacklol7481 yes, Genuine = Aisin. Toyota does not make waterpump or transmission, Aisin make it for them. Denso makes sensors and compressors for Lexus/Toyota. Just make sure you get genuine Aisin and Denso from reputable local stores or welknown online stores like Rockauto, autodoc, a1auto, or even Toyota dealership online stores

Great video. Is this the same as the INVERTER water pump? Or is that different?

[@danb4089]

Inverter is behind front headlight it's plastic and black in colour very easy to change . Google Prius inverter pump and u will understand me.

[@amazoidal]

It just takes a minute to drop the front bumper and expose the two problem makers. One is the inverter coolant pump and the other (GEN 2 only) is the 3 way coolant valve that has 3 hoses and sticks. While you are in there on your GEN 2, change both (Amazon). If you don't drop the bumper, you will be bleeding from the many scrapes and cuts. Be sure to junk the factory hose clamps and go screw-drive clamps. You will need 5 clamps. There is little room to work from above. Minimize your frustration and learn how to "drop the bumper".
