Toyota replacing coolant pump in 650,000 Prius hybrids

I agree with you completely.

 

For all I care they can call it Billy Bob as long as my water pump is replaced for free I'm happy

 

Sorry if I have missed it but is this the same pump covered by T-SB-0087-08 issued on June 5, 2008 for Abnormal Noise from Coolant Heat Storage Water Pump?

 

No. This has been pointed out in detail on various threads about this topic.

For completeness, there are four Prius 2004-2009 coolant pumps:

1. ICE Coolant (a mechanical pump driven by the serperntine belt
2. Inverter Coolant (The electric pump being discussed in this thread)
3. Themos Coolant (The electric pump you are concerned with)
4. Heater Pump (One more electric coolant pump)

So there was a pump making an intermittent squeaky noise during cold weather after I switch the power button off. Last year I noticed it during the cold winter time, but only went to the dealer in March when the temperatures were rising so I could not duplicate it for the dealer. I have not heard it this year. At the time I was told this noise originated from the thermos coolant pump. I'll take it that diagnosis still holds?

Thanks,

 

Yes, that's the one that squeals after you shut off the car. For reference, Pearl's has been squealing for the last two years with no ill effects, other than being embarrassing.

 

Can't believe it. We just replaced the water pump two weeks ago!!!

How do I find out which pump got replaced, and if it's the one covered here? I'm pretty sure my bill from the mechanic just says "water pump".

 

Re: Toyota replacing coolant pump Terrible mpg drop (8 mpg)

I just brought my 2007 for "Limited Service Campaign (LSC) A0N - 2004 through Certain 2007 Model Year Prius Vehicles - Electric Hyrbid Water Pump Replacement".

The minutes I drove the car to Freeway I noticed a big drop in mpg for the 1st 10 miles (normally 52 to 54 mpg after the pump is replaced now it's 44mpg). I called the dealer right away they said bring it back. I will bring back next week. I think Prius owner is very sensitive about MPG.

Does anyone having this same drop after this water pump replacement??

 

The tech may have left the car running for quite a while to ensure that all the air had burped out of the system. When I got my car back after the pump replacement last week the mileage was down about 6 or 7 miles, but now that I have driven it about a hundred miles it is almost back to where it was when I took it in. Changing the pump should not have any effect of the mpg while driving.

 

My appointment is Tuesday morning. Hope all goes well. They always try to sell me extras, like cabin filters, etc. I can do that myself.
I've got 67,000 miles on my 2007 now...is there anything I should have them look at, or for me to look for while it is on the lift?
BTW, I still only get between 42-45 mpg, but I know that is another topic. The new optima battery I installed did not increase MPG that much. My local dealer isn't all that wonderful, although they think they are...;-) They tell me my mpg is normal, and everyone else exaggerates on those "dumb forums"......grrrrr.

Thanks! Frank D.

That is about the same as my mpg. All of us don't get the super mileage some people talk about.

 

I think you are right. The water pump should not affect the mpg. I forgot, my car also had the Gas Pedal replacement do to the recall, would this affect the mpg? I ran over 200 miles to day and it got 41mpg normally I got between 52 to 54 MPG.

 

The gas pedal "replacement" involves chopping a bit off of the bottom of your existing gas pedal. Theoretically you might gain mileage from the weight reduction.

If they ask me about doing the gas pedal or mats, I think I'll decline. IMHO, nothing is wrong, and if it is not broke, why fix it. Am I missing something?
Will tomorrow's work involve any additional cost, like will they want me to pay for new coolant or anything? I guess I'll find out tomorrow.....

Thanks, Frank D.

 

You are totally right. I double checked to see if they replaced with the new one or chopped it off. The Pedal looks newer but I think because they washed/cleaned it. After they chopped it off to make the pedal shorter it looks ok not very professional but not bad!!!

The reason I said you are totally right because I might gain 0.05 mpg; now my MPG back to normal or increase litte bit after I Reseated the Accelerator Pedal Electric connector.

I got 55.5 MPG on 35 mile one way commute to work after I reseated the Accelerator Pedal Electric connector (right at the pedal).

Thanks all, I will write up on the new thread attention to some one with MPG less than 45 MPG to try out (by reseat the Accelerator Pedal Electrical Connector) to see if the MPG improve!! It's only take few minutes and no tool is required (just bare hand and light/flashlight).

 

I read your other post about reconnecting the accelerator pedal lead. This is very curious. I can't imagine what that did. If it wasn't connected properly, I would have expected an error. I'm not saying you are wrong, I'm just saying I can't conceive of why this helped.

Tom

 

I did not see any abnormal about the connector nor error code!! Since you told me they chopped off the pedal, instead of replace a new one. I double checked with flash light and saw they really chopped off a portion of the Pedal!! I saw an Electrical connector at the pedal, they must disconnect in order to remove the Pedal. I think why not reseat the connector even it looks normal. After reseated and drove just few miles; I saw the diff right away.

Anyway I am very happy with the normal mpg reading.

Thanks, for mentioning about chopping off the pedal. This solved my problem.

 

Wow, I really need to get back to spending more time on PriusChat!

I just got hit with this recall info today at the dealership. I wonder what they would have done if I hadn't brought the car here for the oil change. Does anyone know if Toyota is contacting individual owners about this?

Unfortunately I cannot get this done today. Apparently the dealership doesn't have the part (which is pretty strange to begin with).

 

thats funny
here in the netherlands the message from toyota is that because the coolant is replaced and that somethime's air can get in the system and damage the cooland pump.
there are 3 nown here in the EU and because of al the bad press on toyota, toyota decided to replace all pumps...!!! that already gotten that coolant replacement maintenece.

 

Ummmmm...I thought this was called innovation/improvement/evolution/increased-quality. When a problem is discovered, the product is redesigned to be BETTER than the previous version, and all new products sold now contain the NEW, BETTER VERSION, and the problem is eliminated from all future products. Isn't that an IMPROVEMENT in quality?

I get that there should not have been a problem in the first place. But I would not call this a "blow" and drive me away from buying a new Prius. Heck, it would drive me toward buying a Prius because now I know that Toyota is redesigning the part to be better than the previous version. So, by buying a new Prius in a month from now (or 90 days), I would know that I'm getting a BETTER Prius now.
