My 2007 Prius with 162k miles had an Inverter Coolant Pump Failure Monday 6.5 hours from home when my wife was driving it home from a trip. Red Triangle, (!), vsc, and check engine light. She was able to make it about 20 minutes to a dealer where it was diagnosed. Luckily no further damage was done to vehicle. Yes, she should have stopped but continued on since car was driving OK.

I own a 2006 JDM prius with 323,000 km. The inverter coolant pump failed recently (got P0A93 code and no agitation in coolant reservoir). I ordered a replacement on eBay and am awaiting arrival. I may need to do some light driving in the in the interim and am thinking about installing a 10 inch fan in the space between the inverter/transmission and radiator to keep things cool. Is this wise or should I just let the car sit until the new pump gets here?
Also, I am burning oil...I usually have to top up 1 to 2 quarts in between changes. Is there anything I can do without tearing down the engine? A friend of mine suggested using Lucas oil stabilizer the next time I change oil...could this have any negative implications?
Prius (2004-09) Fuel :: How To Determine If Inverter Pump / Coolant Reservoir Is Not Working Properly
How do you know if the inverter coolant pump/reservoir is bad after the recall was performed?Since it doesn't produce any codes but can reduce the electric-drive if getting too hot, how do you convince Toyota to give it a second look?

I loosened coolant pump belt when my gen II prius had only 200 miles on it. I retensioned it approximately 70% less. Where I could turn water pump pully by hand breaking traction with drive belt using all my strength.
The ice coolant pump just started to leak at the weep hole at only 63000 miles and 5 years old. I was sure the reduced tension would make coolant pump last much longer.
After retentioning it (brand new at 200 miles) I could deflect belt about one inch as opposed to not able to deflect belt at all!
Gen 2 Prius :: Inverter Coolant Pump Failures
Having seen the rather catastrophic outcomes that are possible with inverter coolant pump failure, I've thought a bit about adding a flow sensor in the coolant path. I even went so far as to buy a flow sensor, which would probably do the job. However, it's somewhat heavy, and then there's the plumbing job to take care of. Seemed somewhat challenging to pull off.
Since this aborted endeavor, I began thinking about ways to detect surface turbulence at the top of the coolant tank, and am now thinking that might be easier to pull off, even if it requires programming a PIC to do the monitoring. My current thought is to install an LED and optical sensor in the cap, and measure light intensity received.
Prius (Gen 2) :: 2008 / Inverter Coolant Pump Leak?
I'm a new owner of a used 2008 Prius. Car only has 67K miles and other than the leak, appears to be in good shape.
I noticed the coolant was low in both reservoirs, filled it up (with the proper SLLC), but a day or so later the check engine light came on. Took it to mechanic (dealer is 2 hours away), he read and cleared the codes, then found the leak. Appears to be leaking where the lower hose attaches to the pump, so not sure if it's the pump or the hose that's the problem. I've also noticed that the pump seems a bit noisy for a few minutes after shutting off the car (of course, I'm new to the Prius so not totally sure what "normal" sounds like).
Prius (Gen 2) :: Check Engine Light Is On - Inverter Coolant Pump Shot
My check engine light is on and I think the inverter pump is shot. I have a some questions about how and when the pump is on. I have a mini vic on order and as soon as I get it hooked up I'll run for some codes. That is if I get it installed????
1- With the car in "ready mode" and at start up (car cold) should the inverter coolant pump be running.
2- With the car in "ready mode" Should I always see a water moving in the water reservoir.
Prius (2004-09) :: Inverter Pump Noise - No Circulation
I have a big red triangle on the pump is making noises not loud noises sounds like it's operating correctly there is no turbulence in reservoir and when I squeeze the hose the level in the reservoir goes up-and-down which leads me to believe there is no blockage in the pipe coming out of out of the pump.
My handheld scanner and torque on my android tablet only gave me my oxygen sensor code which I know about and I'm going to replace when the weather gets hot I am wondering if the coolant pump would throw a code that these devices would be able to pick up or do I need to go to the dealer or find a shop which is capable of reading the HYbrid codes?
Prius (2004-09) :: Seems Like Inverter Coolant Leaking
So, the sideways coolant tank in the engine compartment, not the one next to the grill, but the one that is sort of between the air filter box and that shiny metal square
I have always thought that tank was slightly low, but it has a seam just about where the full line is, so I was never sure....finally about three weeks ago, I worked up my courage and put a few ounces of coolant in that tank. THEN it was up to the full line.
So, a few weeks after adding the coolant, I had the water pump recall done. Now the coolant level is back down to where it was before I added....so I am assuming that the correct level is just below that seam that seals the top of the plastic tank to the bottom part of the tank.
Prius (2004-09) :: Coolant Drip From Inverter?
I am getting a slow coolant drip from my inverter . The very slow leak appears on the left side of inverter when facing the front of car with hood open . The connection point alum tube to coolant resevoir black rubber tube. The inverter coolant connection reservoir tube side is damp to the touch and has visible red goop buildup.......

I recently had the inverter pump replaced under recall. it now makes a the pump noise even when I am driving. I hear it when car is not fully warmed. Back when it had the original inverter pump, it only made noise at startup and shut off.

I posted a few months that after replacing my inverter coolant that the drain plug leaked. I tried to tighten it but that did not work. New Aluminum washer was installed. I took it in about 1 month ago for the steering shaft and inverter coolant pump replacement. After they drained the system and refilled post inverter pump replacement It still leaks.

Back in February, received a light and discovered that the inverter coolant reservoir was empty. I refilled the reservoir and cleared the code. Today, only 3 months later, the same thing happened. I don't see any wet hoses, puddles, or obvious signs of leakage. Where all my coolant is going? What steps should I use to properly troubleshoot...

My original intention was to replace the engine oil in the car. I was in a hurry(yes....I know) I could not find the oil drain plug. I did find a large bolt which turned out to be a drain plug for the inverter coolant instead. The instant the fluid drained from the car, I knew it was not engine oil. I did not know the drained fluid was inverter coolant. It had the color of a transmission fluid but significantly less viscous.

My 07 Prius is leaking transaxel fluid into the inverter cooling system. Transaxel fluid is sweating through the inverter coolant hoses. Before my taking ownership of this vehicle, it had previously been in a front end collision (that’s a whole other story). Anyhow – if I replace the radiator, should that take care of this problem? Are there any other ways these two cooling fluids could become cross contaminated?

Just noticed my level is about an inch below the full mark, it was fine at the last oil change, no leaks that I can see....nothing on the ground.

I had the red triangle pop up on my Prius. I codes I got P0A93 and P1121 I needed a new control valve and inverter water pump. I installed both the valve and the inverter pump filled it with new coolant and bled both systems.
I went into maintenance mode so I could run the motor and bleed out all the water. My question is the red triangle is still on in my car when I start it up.. Is there some way to clear the red triangle or does it just go away on its own? Not sure what to do.
Prius (Gen 2) :: Regular Coolant Blows Up - Inverter Coolant Runs Low
Inverter coolant runs low and also regular coolant blows up. Do they use one line together? Everyday I have to fill the inverter.
