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) :: 2008 - ICE Water Pump Failure / Engine Coolant Losing
I bought my 2008 JDM Prius a couple of weeks ago, at 84,500km. After a week, it started losing engine coolant. (Great start! Hope it's not a sign of things to come...) Fortunately, covered by a 3 month Dealer Warranty - hopefully. Yet to make the claim.
Anyway, went to the local Toyota Dealer to get some of the proper Toyota SSL (Super Long Life) Coolant to top it up. Got chatting with the Service Agent about Prius Service and what HSD Adjustments are possible (not many) and showed him my symptoms.
Prius (2004-09) :: Water Pump Replaced Due To Failure / Change Coolant For Hybrid System?
Actually 2 very similar questions about my Prius 2007.
1. My water pump was replaced by a dealer due to failure some half a year ago at 95,000 miles. Yesterday, after oil change (98,000), I was told it is recommended to replace engine coolant. Does this sound right? Don't they change coolant when replacing the pump?!
2. Identical question about HV pump. It was replaced at 80,000. Now they recommend do change the coolant for hybrid system. Don't they have to do it when replacing the pump?
I want to do everything necessary to maintain the car. But don't want to spend money for something that is not needed.
Ford Aerostar :: Water / Coolant Pump Failure
This is an update to my Heater Hose to Water Pump Failure post. As it turns out, the water/coolant pump seems to have failed at the same time as the heater hose. I think Ford secretly installed an internal time mechanism to deconstruct certain parts at the same time.
Anyway, in desperation I took the van to the local Ford dealer for an inspection. NOTE: I don't trust most of the locally owned small time shops and national franchises. Half of the time, they don't know what they are talking about.
They said the water pump is toast. And I already knew that! Then they said, because the water pump is attached to the front timing chain cover, they need to replace the gaskets there also, and also the oil pan is attached to the front chain cover, so that needs done, and then they said the radiator is also leaking. What!!!
Then they asked if I would be interested in buying a new or used vehicle. This tool works great. Mine happens to be a left hand fan. The tool is used with the handle on the left. This tool is used to hold Water Pump pulley stationary, while unbolting the fan assembly.
Tomorrow morning is when I finally replace the water pump. Not a lot of tool are needed, except for the stubborn fan clutch. Sockets: 8, 10, 13, 17, except a 22 mm open end wrench for the fan clutch.
Prius (Gen 2) :: 2007 Power Steering Failure - Red Triangle On Dashboard
The 2007 my wife drives has no power assisted steering as of yesterday. This afternoon I drove it around the neighborhood and yup, its like driving a 42 DeSoto.
The red triangle is on the dashboard
NO CEL
NO MFD message - everything is normal
Plugged in my ScanGauge II and there are no DTC codes. Am I correct that this is a failed steering ECU?
Prius (2004-09) :: 2007 - Triangle Of Death / Hybrid Battery Failure
I have an 07 Prius which I bought used in 2011 and which has been fine (except for some A/C work last year) but got the 'triangle of death' this morning and having towed it to my regular shop, they tell me the code (they couldn't give me the number) simply said 'replace hybrid battery'... the car has 102,605 on the clock.

My wife was driving our 2009 prius this morning. she said the red triangle, this other yellow circled, light with an ! came on plus in the display window the car icon with the ! came on. Manual states that this is a hybrid system failure.
On very cold mornings the car smells very hot for a period of time. She said this happened again.
I tried to do a reset (turning it off and on atleast 4 times) did not work. So I had it towed to a dealer tonight and I started it again and this time very hot smelling and a whole lot more lights were on, ( brakes lights, almost all of the lights I would say.)
Prius (Gen 2) :: ICE Failure - Leaking Water Pump Replacement
My ICE failed to start on a wooded forest road -- after the car had sat under a fir tree for a day or three it ended up starting and all the warning lights went away. I ended up taking it to the dealer though and while they replaced a leaking water pump, never found any cause for the ICE failure.

While driving home last night the Red Triangle, CEL and the Hybrid Warning lamp, (on the MFD) all lit up. The cruise control also shut down. We stopped and checked the manual to identify what the symbols meant. We were approximately 90 miles from home, drizzling rain and it was about 60 degrees.

2004 Prius, 98K miles ... I recently replaced the coolant control valve (received code P1121) and added coolant. Trouble codes were cleared. I am now getting the red triangle intermittently. When I drive the car, after a few minutes, the red triangle comes on. I can shut off the car, and turn it back on, and the red triangle comes back after a few minutes. The car seems to drive normally.

My 07 has pretty low miles but is going on 4+ years so I thought I would change the ENGINE coolant. Reading how many posters have struggled with this I thought I would be a smart guy and buy an Airlift which I have used before back in the day on strictly American cars if memory serves.
I had hoped to just hook the airlift up and suck the bulk of the coolant right out without opening any petcocks. Yeah right... That resulted in about 1/2 pint of pink foam and collapsed hoses.
Prius (2004-09) :: Turn Off Red Triangle After Control Valve And Inverter Water Pump Installed
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 (2004-09) :: 2008 - Getting P1121 / P1116 - Replaced Coolant Control Valve And Red Triangle?
So I drive a 2008 and a couple months ago I started getting the Check Engine Light. Codes P1121 & P1116. Found out it was most likely related to a faulty Coolant Control Valve or Electric Water Pump. Since the pump was just recently changed I went ahead and got the valve changed.
The light is still coming and going but now when I go on the expressway that red triangle with the exclamation pops on with a little beep. Only pops on for a couple seconds and keeps coming back until I drive a bit slower.
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) :: Engine Coolant Pump Replacement Due To Leakage?
I'm sitting at my Toyota dealer where I bought the car 3 weeks ago. My car is in because it needs to have the engine coolant pump replaced due to a leak. Is this a common fix for the gen 2 Prius? Fortunately this is getting covered under warranty.
