Prius (2004-09) :: Loud Obnoxious Noise From Front Left - Coolant Heat Transfer Pump?
Nov 21, 2010
I know that you're supposed to hear a soft whining noise when starting up and shutting down the car, especially in cold weather. For at least a year now, the noise coming from my front left has gotten much louder and more obnoxious, especially in cold weather.
From what I've seen on this forum so far, I think it is the coolant heat transfer pump. Does that sound right? Or could it be a different pump or piece of some sort? Seems like there has been confusion on this issue, from other threads I've read.
The noise has gotten louder and longer, it lasts about 10-15 seconds now. Especially in the winter, it sounds really bad, I'm afraid the pump is going to fail this winter.

I'm getting a noise that sounds like "woooooooooo" from the right front of the engine compartment when the outside temp gets below about 20F and I just start the car. The colder it gets, the longer the noise lasts.
I suspect it's the pump that's part of the CHS. Just a very wild guess. The noise goes away when the car starts to warm up. No drive ability problems.

Over the last few weeks I've been hearing what sounds like a failing pump of some sort when shutting off my '06 GX470. The sound lingers for just a moment after the ignition is cut off, and sounds like a loud, very fast tatatatatatatata. It doesn't always do this - sometimes I don't hear anything. I've been commuting in the GX for four years and I've only been hearing this intermittent occurrence over the last 3-5 weeks.
What this might be? Fuel pump? Air leveling suspension pump?

I have a weird noise from my 2007 Prius. It seems to be coming from the front left of the car. The car drives well, Tracks, feels stable at all speeds. It's just making a crazy noise at almost all speeds, it starts around 10 mph. It's a very DEEP ggggrrrrrrrrrrr. When the car is shifted in N it continues.

I just bought 2008 Prius (60tkm) and now i am wondering about noise coming from left front. It sounds very much like my older car breaks. High pitch squeezing noise. But it:
- doesn't appear immediately when you start driving
- doesn't appear on normal driving speed (> 30-40 km/h), or i just couldn't hear it
- does appear when driving very slow
- does appear when accelerate gently
Something with breaks? Sound is very loud.

I have a 05 Prius. Developed a low hum noise some time ago. It now is so loud can't hear the radio. Sounds like a heavy agressive truck tire rolling down the road. When turning the steering wheel from right to left quickly, noise level changes. Does this sound like a bad wheel bearing and if so what am I looking at for repair costs?

I am running into issues with my 3GS recently I am hearing loud ticking noise coming from the left side on the front of my car and from what most of people have told me is it might be my Axle or my wheel bearing so was wondering what the part number was for both of them and what is the best place to order these two parts from.

I have a 2004 Dodge stratus recently it makes a really loud noise for like 15 seconds then stops if I have the heat or air on. If I don't have it on it doesn't make the sound but either way after 15 mins of driving white smoke will come out of the passenger side and a funny smell. It starts fine isnt overheating, and drives fine.

I own a 2004 VW GTI VR6, with 70k miles. i bought it used (at 40k) from carmax. Ever since I've owned it I have had a problem with a single loud knock sound i can hear from my front left wheel.
it happens in two scenarios1) when i back out of a parking space and start turning my wheel - it's only a single knock (hence i don't think it's the CV, and its been pretty constant for at least 2 years), and happens at about halfway through the steering wheel travel.2) it also happens when i accelerate hard, or decelerate. it's a single knock, or pop, or clunking sound. it almost feels like something is loose, or reseating itself as the car puts pressure on the wheel as i accelerate, and then again once again when the car decelerates.
it's pretty damn loud, and disconcerting... i can feel it in the steering wheel as well. it seems to be louder when the car has not been driven for a few days.
I've taken the car back to carmax several times over the past three years but they have not been able to find the fault. they have replaced my engine mounts twice (in 30k miles that I've had the car), which i also think is a little weird. they have also replaced all the tie rod ends, etc. - all the obvious stuff.
I am at my wit's end here - carmax pretty much think I'm crazy, and my warranty has run out, but i think I've bought a car that was in an accident - i'm expecting my front end to fall apart one day as I'm driving...

I was pulling out of the driveway and heard really loud snapping noise. Jumped out of the car expecting to see damage, but everything looked fine. I didn't drive over anything or hit anything.
Now, I notice that when my left front wheel goes over bumps and potholes there's this metallic rattle. Took it my mechanic right after and we both looked the front suspension over. Everything looks good. It does drive fine.

First background: G2 car has 215,000 mi and recently got P1121 scan code, so I replaced the coolant control valve. that's when high coolant temp and no cabin heat started.
on CCV top nipple connected to hose that had a dot on it and hose goes under inverter cover on right, next nipple down went to hose slightly to left of first hose, bottom hose goes to thermus can. initially ran car in diag mode with high heat, no heat in cabin.
so I got a Autel 519 scan code reader and I see now that the only code is a P0505 (idle air control malfunction)
taking car down my road for short test run, I turn off cabin heat completely and watched the ECT. after a while it climbs to around 220, then while engine is running quickly goes to 245F then 260F. At that point in time (around 245F) the high temp indicator lights up, temp stayed at 260ish so I return home. With car in park, cabin heat off - the temp returns back down to 220F. if I rev the engine temp again climbs.
I have gone through all suggestions, open radiator bleed valve, manually 'pumped' coolant hoses, turned on/off high heat in cabin and finally with car off removed and jumped the CHS multiple times for about 20secs.
Have purged the coolant system over period of days and coolant appears to be full as level is near top of radiator cap, no bubbling, no gurgling.
However 2 mentioned problems continue... I am starting to suspect coolant thermostat but it would seem strange that it would go at precisely the same time as coolant control valve.

I've got a loud, intermittent, swooshing, vibrating noise from the front left wheel area at highway speeds. I put a camera down there and saw that when there was noise, the front driveshaft and front left halfshaft were spinning. When they stopped spinning on their own, the noise stopped. Hubs are Warn Premium (gold) and unlocked. Unit bearing already replaced. What could it be?

I applied brakes while car was moving slowly, less than 10 mph, and heard loud grinding sound coming from left front as car stopped. Shifted to reverse and car barely moved, less than 1 foot, which was accompanied by the loud grinding sound, then stopped. I could find nothing interfering with the wheels but did find pieces of brake pad on the ground along the path the left front wheel had followed. The left front wheel appeared as if the calipers were holding whatever remained of the brake pad and/or backing tight against the rotor. brake pad fell apart on 2002 at 43,561 miles...

My 2006 Prius with 120k miles has coolant seeping around the water pump. I called around to get quotes on replacement cost, but one place said the thermostat should be replaced at the same time, while the other said it shouldn't. (BTW, I will have the belt replaced at the same time).

I have a 2009 Toyota Corolla and it's making a loud grinding metallic noise on the front left side. It does it while I drive the faster I go the louder it gets. When I turn to the left it makes it louder, when I turn right the noise decreases. PG&E have been breaking the roads by where I live and there's a lot of little rocks I drive thru. I'm wondering if that's the problem?? What do I do?

I have been experiencing loud popping and static/feedback sound from my front left speaker or tweeter. I replaced the jbl speaker with used jbl speaker. But it seems that my tweeter is done for as well. No sound comes out of it. Is it best just to replace it with a new jbl tweeter or are there better options that fit with not a lot of work.

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.
