What could cause loud clicking/clunking sound from front. Temp gauge fluttering

Loud clicking clunking sound started after making a sharp u-turn. Not when car is stopped and in Park.
Temp gauge flutters from hot to mid-range and then back to hot and stays there.

My car has 198000 miles.
My car has an automatic transmission.

Hi There,
it sounds like you may have two separate issues going on here. The clicking/clunking noise sounds like a bad CV joint. A CV (Constant Velocity) joint is a shaft that connects the transmission to the wheels, essentially transferring the power from the drive train directly to the wheels. The CV joint is packed with a special grease and sealed tight with the rubber or plastic boot, that is held in place with two clamps. The most common problem with the CV joints is when the protective boot cracks or gets damaged. Once this happens, the grease comes out and moisture and dirt get in, causing the CV joint to wear faster and eventually fail due to lack of lubrication and corrosion. When the CV joint becomes damaged or worn, you may hear a clicking, clunking or popping sound coming from this area as the weight of the vehicle puts pressure on this area and shifts back and forth and side to side.

The temperature fluctuation is a result of some part of the cooling system functioning properly. Overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, a clogged radiator or a failing coolant fan switch. As you may know the coolant fan switch helps to maintain the proper coolant temperature by turning on and off at specific temperature thresholds. When this switch is not working properly, this can cause the fans to come on intermittently, all the time or sometimes not at all. When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. When your thermostat is not working properly or is stuck closed, this will not allow the coolant to properly circulate through the engine, which may cause the engine temperature to fluctuate erratically or in some cases just remain hot. You may also have a water pump that is beginning to fail. Water pumps often times will begin to produce a bit of a whining sound when they are starting to fail. A common problem also associated with this is the water pump may begin to leak around the water pump shaft due to the seal being damaged. In addition to leaking around the pump, you may have a leak elsewhere in the cooling system coming from one of the hoses going to or from the radiator. Lastly, you may have a failing cylinder head gasket allowing coolant to leak from the water passages into the cylinders resulting in the coolant being burnt in the combustion chamber with the fuel. If this is the case, you may also notice a bit of white smoke coming from your exhaust which is a product of the coolant being turned into a steam like vapor. I would suggest having an expert from Your Mechanic come to your home to diagnose and inspect your vehicle.

How to Identify and Fix Common car Problems ?

If your car is making clicking sounds when driving, a likely culprit is low or dirty engine oil. Motor oil lubricates all of the components so that you can drive with ease. If you are running low on engine oil, the metal parts may start to tap and grind over time.
There is a wide variety of possible causes for the clicking sound when driving your car. However, the most common of them all are faulty CV joints, loose wheel nuts, bad struts, loose drive belts, low engine oil, faulty battery, inadequately inflated tires, etc.
A clunking, rattling, or squeaking noise from your front end while driving can be annoying and unnerving. Oftentimes, this noisy symptom means there is a problem with your vehicle`s suspension system. These sounds typically occur when driving over uneven surfaces, bumps, or potholes.
A distinct clicking or ticking noise emanates from the high pressure fuel pump that can be very noisy during cold starts and quietens following engine warm-up. The sound is more noticeable when standing outside the vehicle, with the hood up, or when the vehicle is next to a building such as a drive-through.
When a vehicle is making popping or clicking noises from near the wheel, it could be a sign of a serious issue. Continuing to drive a vehicle that has damaged struts or CV joints could result in more severe damage, and an unsafe vehicle to drive.
Click & Clunk is a strategy used during reading that allows students to monitor their own comprehension. While reading, students pause intermittently to determine if they understand the content.
Car exhaust systems and car engines make whirring, clicking, or sputtering noises if there`s a faulty belt, alternator, water pump, or tension pulley.
Wheel bearing noise can be classified as one of the following unusual sounds: Snapping Or Clicking Noise: A snapping or clicking noise from under your vehicle is normally caused by excessive bearing endplay. You`d typically hear this noise while cornering or making sharp turns with moderate speed.
Car exhaust systems and car engines make whirring, clicking, or sputtering noises if there`s a faulty belt, alternator, water pump, or tension pulley.
A vibrating sound could indicate a bad wheel bearing and a clicking noise while turning can indicate a bad cv joint. The wheel bearing is what the wheel rotates on and the CV joint is what connects the transmission to the wheel bearing. It is possible that you need both.

My 2003 ford explorer wont start up just get click click click click click click click click
ANSWER : If the battery is weak and the voltage is dropping to below 9 volts you will get the clicking without the starter turning the motor. Have the battery voltage checked and if battery cannot hold a load then replace it and clean the battery terminals and recheck system to see if it starts.

Temperature gauge does not work – 1998 Mercury Grand Marquis
ANSWER : You will need to test the computer to scan for data of the temperature sensor to see if the computer is reading the correct temperature as tested externally on the coolant sensor. If the sensor is not accurate then replace the sender. If the sender is accurate then you will need to have the temperature gauge replaced.

Clicking sound appears during decelerating. What could it be?
ANSWER : Hi there. What you could be hearing is the chain in the transfer case. If the chain has too much play, then the chain will rub on the transfer case housing when not under a load. Try going up a steep hill. If the noise is present under load, then the chain is stretched. I recommend replacing the chain in the transfer case if its rubbing the housing. If you need further assistance with locating the clicking sound, then seek out a professional, such as one from Your Mechanic, to help you.

Loud sound from engine/Front near or under Front seats
ANSWER : It sounds like you may have a loose heat shield on your exhaust. These heat shields are installed to prevent exhaust heat from reaching other components of the vehicle. These shields can often rust themselves loose and cause this rattling sound you are hearing. I would recommend having a qualified professional inspect your exhaust system to determine if any heat shields are loose. If so, depending on what they are shielding heat from, you can just have them removed. If they are protecting anything important however I would recommend having new ones installed.

Engine has a clicking sound at the front of the motor. Continues to click and seems to get quieter when accelerating 2009 Honda Odyssey
ANSWER : Hi there – your Odyssey engines valve train is adjustable, and requires an occasional adjustment, or you get a bit of clicking as you have noticed. Make sure the proper engine oil is in the engine, and that there is no sludge buildup – improper weight oil or a sludged-up engine will cause clatter with this engine for sure. I recommend a valve adjustment performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, and perform this maintenance service.

My tahoe is making a clicking sound in my front left Tire. I changed my wheel bearings an it still making that clicking sound.
ANSWER : Is your Tahoe 4 Wheel Drive? If so, there are front drive axles that have rubber boots that will often wear and the grease will leak out as you drive. Once the grease is gone, the joints are no longer lubricated and can make noise as they make contact. If the vehicle is not 4WD, sway bar links and worn control arms bushings are other items that may click and make noise as the suspension travels. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look as your suspension noise to offer a more personal diagnosis.

Knocking sound at the front end
ANSWER : The first thing is to duplicate the problem with a mechanic because they cannot fix what they cannot hear. Most mechanics want to verify a problem, so they can see if the problem is fixable. The noise is most likely coming from the lower control arms of the suspension or the struts. Only a thorough inspection and verification can find and solve these problem. I recommend having a mechanic drive it with you to duplicate the problem and then have an experienced mechanic inspect and diagnose the steering and suspension noises.
