It seems that the radiator fan is hitting against the frame and so there is noise and vibration when the fan comes on. Shut down engine and check on the blades, see if there was any damage that would have changed the alignment or postion of the fan. If so you will need to remove and reset the fan. If the bearings or blades are seen to be faulty , replace them before the radiator is damaged.

2006 Nissan Sentra 1.8 with bad engine rattle it started with a tapping sound but increased to more like shaking a BB in a empty pop can.


might be the thermostat for the radiator to engine is sticking or broken for the heater problem. could be the fan/blower connections? so many things here? the heat could be the thermstat or the heater core are bad. the rattling noise could be in the trans-axle depending if auto or manual? also, a sensor could cause this noise? depending on where it is? find where it is located and then respond. could be oil not getting up to the top of engine where cam can make noise. so many possibilities.

VW Golf 2007 1.9TDI, I was recently in a accident approx 20mph, and crashed head on into a turning car. What is making the kinda rattling/clicking noise, more noticeable during gear changes.


This could be almost anything from loose trim to broken body parts, you should get the car checked by bodyshop to make sure that it is safe to drive

2006 Dodge Stratus Noises


It sounds like you have a new old car!!! Noises could be so many things, but since you mentioned you had a muffler replaced, my first suggestion would be the exhaust pipe or new muffler is too close to a frame or out of line. Put car up high enough to where you can roll all around the undercarriage. Start the car and let it idle while you roll around looking and listening, and you will have a 90% chance of isolating your annoying rattle. Good luck!

Pt cruiser starts finethen loops at 2200rpm i have changed all sesnsors still no change


Your sensors may be doing exactly what they are meant to do, but it wasn't a bad idea to change them as a starting point. Have you noticed poor cooling from the a/c as well? Open your hood in the driveway and check that your electric radiator fan is turning on regularly once the car warms up. There is a fine dance between the electric radiator fan, the a/c compressor, and the idle sensors on this car. If your problem resolves itself at highway speeds & reoccurs when you stop, then the problem is that your electric radiator fan is in need of replacement. The brushes inside that electric motor do wear out from use - especially in a hot climate - and are not designed to be replaced by a home mechanic. You can have the electric motor rebuilt by a electrical shop - or just replace it yourself with one ordered at any parts counter. When the cooling fan does not switch on at idle speeds, the a/c compressor will overheat and cause it to vent freon to save itself from permanent damage. The overall excess heat buildup in your engine compartment also causes the idle problems where it will surge up and down in slow traffic or at a stoplight. When I changed that motor it solved many inter-related issues that I was having.

When th engine is running there is no noise but when my Engine fan starts a loud noise comes from it.


Is the fan hitting the radiator - then the fan bracket is either broken or loose. If it is not stricking the radiator then you have a bad fan motor.

Noise when driving & idling, sounds like a loose fan/belt/rattling noise. any inputs? Thanks


Sounds like a rattling noise is a bearing going bad to me.

If disconnecting the belt gets rid of the rattling, I would check for binding or loose pulley bearings.

Rattle/Vibration from front of vehicle when idling at stop


Hi and welcome to FixYa. Please try this:
GO out to the car, and lift up on the hood. Does it raise a bit and rattle? If so;
Open the hood, and look at the perimeter of the front radiator support. You will see 2 small rubber thingys, that look like that they are screwed onto the metal that is holding the radiator. Unscrew them a little, and close the hood. Pull up on the hood and see if the rattle goes away. If not, repeat unscrewing the rubber things until the lift disappears.

A FixYa rating (4 blue diamonds) would be greatly appreciated for my assistance.
