2004 Sienna under engine noise

Vibrating plate-like sound coming from under the engine which seems only to happen when car is idling. I took it to the dealer. They apparently removed a heat sheild that was loose. It still makes a sound. In fact it's louder.

Why would the sound of water flowing through a tube happen when we start to accelorate?


The sloshing noise may be caused from air in the cooling system.

If there's air in the system, it ends up in the heater core because it's the highest point in the cooling system. When you accelerate, the water pump spins faster pushing coolant into the heater core forcing the air out causing the sloshing noise.

To remove any air from the cooling system, get the engine up to operating temperature. With the engine idling loosen the upper radiator hose clamp. take a small flat bladed screwdriver and slip it between the upper radiator hose and the radiator hose neck. Allow the engine to idle until all that comes out from the radiator hose is coolant. Retighten the hose clamp.

When I first start my truck I can hear a loud rattling sound coming from the back. Hear this sound also when I am in idle. Don't notice it when I pick up speed.


Check to see if one of your brackets holding the exhaust pipe has come loose. That'll make a rattling sound - especially if it towards the end by the tailpipe. When you're accelerating - more air is forced thru your exhaust at a faster rate, so it's not moving as much as when you're sitting still and the truck is just at an idle with less air/exhaust moving thru the tailpipe. If it's only making the noise while the truck is stationary & the noise stops one the truck is moving - that pretty much rules out anything to do withe the drive-train or suspension. You are sure the noise is from the back & not coming from under the hood? If under the hood - check your oil level ASAP.

Rattling under car -- especially when steerling wheell is turned both ways while parked, in reverse or forward or netural . bmw 230 series


while driving at higher speeds you may not notice a sound as much as when you are drivng in reverse as you usually drive slower in reverse. This leads me to think that the rattling can be caused by a loose protective plate under the car. When a load is put on the engine, it tends to vibrate more this vibration can cause a lose plate to rattle more. This is the cheap answer. That is if you are definitely sure the sound is coming from under the vehicle. Otherwise, you may have a crank shaft problem or a seal in the bottom half of the motor could be bad. You may want to crawl under the car and try to shake some of those plates underneath. If none of them are loose take the car to BMW it shouldn't cast anything for them to look at it unless they have to hook it up to the computer.
Please remember that if you intend to climb crawl under your car, you must make sure that your car is properly supported to prevent serious injury. Also, if your driving with a loose plate, it could easily fly off while driving or if you hit a bump. This could cause serious damage to your vehicle. Also, please check you oil levels and make sure you do not have an oil pressure light coming on when you hear this noise.

2004 Ford Taurus V6 noise underhood appears to be belt


Sounds like a bad idler pulley,or belt tensioner. Most likely not water pump since the check engine light is not on. Altho it couold be the water pump and for some reason (bad sensor, burnt out light) the check engine isnt coming on. Either way it would be best to have it looked at.

Rattling Coming from Engine At low RPM (stopped) and when accl.


If this sounds like a tin can rattle it is likely a loose heat shield on top of the catalytic converter. They come loose after time and corrosion take their toll.
