Hot Coolant Transfer Pump issues, part 2

Did you explain to your dealer that this is unacceptable?
B)

 

Last time I had my car serviced I took an almost 60 MPG hit, from about 80 MPG to 22 MPG. Of course, I dropped the car at the dealer after driving it only one mile after I filled it up at the gas station and for most of that mile the car was in electric mode.

 

about the battery, tideland prius... one sat on DH's lot for a month and was fine after the new ecu. they probably pushed it out, but if it was underground, they may have needed a lot of guys to do it! they might have a car mover too. like a grocery cart pusher but on a bigger scale

thing about the bars of battery charge is, most dealers/techs don't get it. they don't drive one. they don't realize that your all-important mpg is at stake, those bastards! :lol:

 

I took my prius in for this a month ago and of course it warmed up to 50 that day and the sound went away. Told them to keep it overnight, and they heard the sound and parked my car next to another brand new prius and heard the same sound for it, so they gave me the car back saying there was nothing wrong with it. I'm thinking that the problem is something BOTH cars have in the cold. Now that it is 15 degress out it REALLY makes a lot of noise. Sad, crying for help kind of noise. Sounds less like air being pumped than the bearings in the pump giving out, perhaps because the lube is too solid in the cold? But as someone else pointed out, why didn't it do this last winter?? Thick lubricant would also explain why after the pump is used recently, the noise is quieter.

Anyone know the magic words to get the dealer to replace the pump? Or since I have 18 months on the warranty, should I just wait until it fails completely?--which seems imminent, given the awful sound. Can one get stuck in a complete failure? What is the capacity of the thermal bottle? Is it high enough that the car will be short on coolant should the pump fail completely with the bottle full?

I feel bad for my car...help!

 

at this point in time no one has reported a coolant leak just the squealing noise. If this pump leaks coolant the ICE will be short of coolant as the pump is down low behind the LH headlight. Just make sure no red coloured puddles under the car when you back out of the garage/carport/parking spot/gas startion/etc.

 

What I'm wondering is slightly different than a leak. When the car shuts off, it puts X liters of coolant into a thermal bottle. If the next time I start the car the pump has completely failed that coolant is stuck in the bottle and is missing from the system. How much coolant is it that will be missing? Is it enough to matter? I bought the special red coolant at the dealer. I'm assuming the car will draw from the overflow in such a situation and I can top that up to travel....? Got a lot of holiday driving coming up and if history is any lesson, it will be in the middle of a snow storm.

 

non is missing as the system is a closed loop. The pump circulates coolant depending on which source is hotter. The ICE or the thermous. There is temp senders in both the engine and the thermous and the coumputer determines which source is hotter and pumps from the thermous if it's the hotter and doesn't pump the ICE coolant if it's hotter on start up. On shut down if the ICE is hotter the pump circulates the hot coolant to the thermous and the cooler fluid in the thermous is sent to the ICE.

 

well, if you want a new pump, all you have to do is ask. but if there's nothing wrong with it, it's not going to be covered by warranty.

 

Ah, thanks. That's good to know.

And yes, I could certainly pay for a pump, but since brand new Prii have the same trouble, I'll wait until it fails, which should be before the warranty is out but after they fix the problem so the new one doesn't have it.

 

ay! sorry they have no communication skills over there either, Tideland Prius...

think you should definitely go elsewhere next time!! yikes.

 

where did I say to take it? Apparently he's one of the best on the lower mainland but it'd be an even bigger problem if he killed it as it's at least 30 miles from your place. There used to be a good Prius tech at Grandville Toyota but I can't remember his name so couldn't call and see if he's still there. YC15 use to use him all the time and as Andrew isn't associated with YC15 anymore can't call and find out who the hot tech is anymore. Sorry that your Priusless for the weekend.

 

I notice a new avitar, is there a little one in the galaxee?
