Why does my car making a ticking noise when it's cold?
For weeks, my car has made a ticking noise when it's cold. Sometimes it's very loud, sometimes it's only quiet, but I haven't been able to have anyone listen because obviously the car is warm by the time I get to any mechanic. The noise sounds a bit like something hitting the spokes of a bicycle wheel as it goes round. Yesterday evening, the check engine light came on, and I very much suspect it is to do with what is causing the ticking but there's no way I can get to a mechanic for a while and I need to know if the car is safe to drive. I drive a 1.2 Kia Rio btw.
Why is my car making a clicking noise?
Heating and Air ConditioningA car's climate control systems include components that can can produce a clicking noise if they fail or require service. One of these components, the heater plenum, contains devices called blend doors that control the mix of cool air to warm air as the user switches the controls from one climate setting to another. These blend doors run on an electric actuator that can produce clicking noises when it fails. The air conditioner compressor may also make a soft clicking noise if its refrigerant supply has run low.Belts, Joints and SupportsMany of the support systems on a car can cause a clicking noise if they malfunction or wear out. Struts and shock absorbers include hydraulic dampening valves that will click or rattle if they lose their internal oil pressure. Worn CV (constant velocity) joints on the front axle can also make clicking or popping noises, Damaged CV joints make a pronounced clicking noise when accelerating or making sharp turns. Additionally, a loose serpentine belt can cause a clicking sound. Replacing the belt's tensioner can alleviate the problem.ElectricalLow voltage from the car's battery can lead to rapid clicking or ticking noises when the driver tries to start the car. As a battery ages it may lose its ability to deliver a consistent 12 volts of electricity to the starter. In this case, when the driver turns the ignition key, the starter turns itself on and off rapidly, resulting in a rapid succession of clicking sounds. The driver may have to replace either the battery or the alternator that supplies electrical charges to the battery.In short there are many reasons it could be doing that .Today's cars have complex systems with many components, many of which can cause a clicking, tapping or rattling noise when they start to fail. Drivers experiencing this unusual sound may have to let a mechanic examine the ignition, climate control, electrical, exhaust or other systems to track down the cause of the problem. Some clicking noises signal a simple replacement part, while others may warn of imminent engine failure.However I don't think anyone will be able to help you here without knowing a bit more information. Please tell us the vehicle in question . Make model year ? Also when does this clicking noise take place? Thank you and Good luck.
Ticking noise only when cold OUTSIDE?
Valves, (valve lifters ) need oil to take up the gap in the system. But when it is cold out, your oil has to warm up before it circulates well. Let your car warm up in cold weather and it will be fine. Running a lighter (thinner) oil will help too. Not a big problem
Why is my engine making a ticking noise on cold startups?
My 2003 Pontiac Sunfire engine has been doing this for a little over a year now. Sometimes on cold starts, my engine has a loud ticking noise it does anywhere from 5-10 seconds. Not a knocking sound, but a loud, fast-paced ticking noise. Now, when I hear this sound, I immediately turn off the engine and let it set for about 3 seconds and restart it. When I restart it the next time, it sounds as good as new. I always change my oil every 3000-3500 miles, I use the best filter, and I just now started using Lucas Oil stabilizer. I always check my oil, it barely uses any. It idles and drives very good for its age. Anyone have any suggestion as to what it could be or how to fix it? I just want to make sure my engine isn't completely trashed or about to explode. I take good care of my car. If its just one of those harmless engine noises that's just there, that would be great. I can live with that. Can some one please help me?? Thank you!
What’s that crackling noise when I turn my car engine off?
Most likely, the crackling noise is caused by the rapid cooling of thin sheet metal heat-shields that are located around exhaust components. While all parts of the engine cool down, heat sheids are the extreme because of the very high temp they see, and because they are thin, they cool rapidly. The sounds I hear on my car are very tinny, so heat shields are the source.
Why car is ticking after warm up?
Sounds like you need a valve adjustment. The sound is the tappets, the part on the rocker arm that makes the valves open and close. If they are worn, they'll make a characteristic tick, tick, tick noise. If you're a DIY type, here's a youtube vid of the adjustment proceedure on a Honda S2000: http://www.youtube.com/watch?v=YguimOCYC... just be sure to refer to your vehicle's operating manual for the correct settings, as these may vary from your model Or you can simply add the proceedure to your next tuneup, and should be done every other oil change/tuneup. It's not that much more to have done professionally, and will extend the life of your engine.
Clicking noise upon acceleration in the cold?
When it is cold out it takes longer for the oil to reach the top of the engine. Especially living in florida, i am sure you dont have a thin viscosity engine oil since you are not used to the cold temperatures. Because you are saying it stops when the engine is hot, tells me that it is just taking a little longer for the oil to reach the engine, because it needs to be warmed up. This is simply your pistons moving up and down without lubricant for the first couple minutes the car is running cold. No worries, but i would start the car and let it run for a few minutes before driving it to allow for the engine to warm up and get the oil flowing in the cold temperatures.
