Prius (Gen 2) :: Inverter Coolant And Transaxle Fluid Change
I just got a 2006 Prius and I brought to Toyota dealer to do a regular oil change. After that, been told that I'll need a Inverter Coolant and Transaxle fluid change in next maintenance point.
This prius already has 111,000 mile now.
Prius (Gen 2) :: Inverter Coolant Fluid Level - Small Leak?
Changing my oil today, been awhile since I had the hood open for an inspection a year maybe about 5 - 6K miles
It's been about 2 years since the prior owner had it in for a service, I recall they had it in right before we purchased it in August 2008
I live in Miami Beach where it's HOT
I noticed the inverter coolant level is no longer at full It's hard to see where it's at, actually
It's not below low, and it seems to be at least up to the bottom of the double seam that wraps around the tank, but I can't see where it levels off behind the seam
Should I be concerned enough to take it in to the dealer and pay them to hunt around until they find a small leak, or is it normal to lose a small amount of coolant over the course of a couple years
Should I just buy their high priced Toyota Super Long Life Coolant and top off the extra 1/8-1/4" or so until it's at FULL?
Prius (Gen 3) :: Check Hybrid System - Inverter Coolant Reservoir Empty
1,500 miles ago my car had it's 30k service. Today, i got "CHECK...". At home this evening i checked the inverter coolant reservoir, it was empty. I've added 1L of de-ionised water (which got it to full, and i see turbulence in the fluid) until i can get the correct fluid.

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.

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...
View 8 RepliesPrius (2004-09) :: Inverter And Transaxle Coolant Cross Contamination
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?

We seem to be getting reports of failed inverter coolant pumps here on just about a daily basis. I'm wondering if they're all just failing now or if this is something of a "backlog" of failures that started in Winter but are only really being detected now.

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?

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 have a 2007 Prius, and bought it used about 4 months ago. I have not had any issues with it until last night. Last night I was driving home and the red triangle with the “ ! “ in the middle and check engine light came on. The car seems to be running fine, but it scared me to see the lights come on...so this morning I called my local Toyota dealership.
NOTE: I recently went to them for an oil change and they informed me that I had three recalls on my vehicle that needed replacing, but I did not get them replaced because I was told it would take 5-6 hrs (which I didn’t have at the time).
Anyway, they told me that it would cost $70 to have the codes read...and that did not include parts that may need replaced... I thought that sounded a little high for just having the codes read so I went to my local Autozone and they gave me this code:

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?

What the heat losses are approximately kwh from the transmission and inverter are. I understand this will vary with speed and driving conditions but reasonable estimate will do.

View 13 RepliesPrius (Gen 3) :: Inverter Coolant Reservoir On Low Mark
I have had my certified 2010 Prius since June 2015. Last Saturday I noticed my inverter coolant reservoir was on the low mark. I went to the closest dealer and they topped it off up almost to the full mark for free. I thought it had probably went down from evaporation and I just hadn't noticed it before. Yesterday I went back to the dealer where I purchased it which is about 90 miles away to have the CVT fluid changed. This morning the coolant was back down to almost the low mark. I looked on the ground and can't see any evidence of a leak. Tomorrow I have a appointment to have them check it. Since it is still in the one year certified warranty I don't know how motivated they will be to find the problem when they can't charge me for it. I don't think the level would have went back down right away if there wasn't a leak somewhere. I checked and there have been no recalls done or called for on it.
