Sounded weird when I started it, steering busted
Right when I started it up, I noticed that there was something wrong with my 2006 Kia Sorento. The power steering was nonfunctional and the sound was just… off. I looked under the hood and the fan belt was not moving and looked loose. This car has 76,000 miles on it, will this totally ruin the engine? I want to know what to expect going into this repair.
Experienced mechanics share their insights in answering this question :
Hello, thanks for writing in about this problem!
The belt not moving generally indicates that the crank bolt is broken, causing the crank pulley to become loose and the belt to become disengaged. Technical Service Bulletin (TSB) KT20060425001 for 2003-2006 Sorento Crankshaft Bolt Torque Guidelines was released, stating specific bolt handling instructions including hat any time the bolt is loosened or removed it is to be replaced with a new bolt and that bolts should be hand tightened.
Crank bolt failure often occurs after a timing belt adjustment has been done and the bolt is either not replaced or the new bolt is installed and tightened with an impact gun. The part number for a new bolt is 23127 39801 and washer 23126 32021.
The rest of the items behind the crank pulley should be inspected for damage as well, including the timing belt drive gear, crank shaft sensor plate, and the two woodruff keys. If you are already inspecting the items behind the crank pulley, it would also be a good time to check the timing belt and replace it if necessary.
The crankshaft bolt breaking is currently in litigation with a class action law suit, with an outcome yet to be determined.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Power steering can withstand some less-than-ideal road conditions, including potholes, unexpected bumps, or hard jolts against your wheels. However, it`s important to remember that your system isn`t invincible. Pumps, belts, and other steering system components can break if put under too much stress too quickly.
Another identifier to watch out for is a sudden squeaky noise coming from the engine. If you ever hear a grinding or squeaking noise coming from the engine when you turn the wheel, then that is a really significant indicator that your power steering belt has seen better days.
It is not recommended to drive a vehicle without a power steering pump belt, as it can make the vehicle difficult to steer and can cause damage to the power steering system.
Your timing belt helps run many fundamental parts of your car, including the vehicle`s engine, alternator, air conditioner and power steering pump.
This can lead to a sudden lost of power assist for the steering system, leading to the steering wheel all-of-a-sudden becoming very hard to turn. A broken serpentine belt may stop the water pump from circulating coolant through the cooling system, causing the engine can overheat.
If the belt breaks while you are on the road, the car will break down immediately – and your engine can experience severe damage. You need to look out for signs and symptoms of a weakening timing belt so that you can take action before it is too late.
The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and—in some cases—your water pump running smoothly and effectively.
Most belts are designed to last between 60,000 and 100,000 miles. However, yours should be inspected at every single maintenance interval (every oil change). This ensures that you`re able to keep an eye on the belt`s condition and catch it before it fails.
When this happens, the belt can slip off or break from the drive train. This means the power steering pump pulley is not working correctly. A professional mechanic will need to diagnose the issue as to why the pulley is not working properly and causing the belt to slip.
Alternatively, your timing belt can “jump a tooth” causing your vehicle to suffer from loss of power. You will notice rough running conditions; including, odd idling and flashing check engine light.

Serpentine belts generally last anywhere from 50,000 to 100,000 miles, but they can fail prematurely if your car`s fluids leak on them, such as engine oil or coolant.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.

Engine tapping noise related to short term fuel trim but only on cold start up.
ANSWER : Has a mechanic’s stethoscope been used to track down the specific location of the noise? There are several solenoid valves in the engine bay that do not run all the time and may be pretty loud once they start, such as an evaporative emissions purge valve and the like. The high fuel trims on one bank sound like you may have a problem on one side with a vacuum leak. A positive trim means air is being added and the computer is trying to add fuel to compensate.
I recommend having an experienced technician, such as one from YourMechanic, come to your location to determine why the engine is making a noise and suggest the proper repair.

Cranks over start than dies
ANSWER : Hi There,
The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor. This is controlled by the car’s ECM which uses this information to make adjustments to the air/fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things. As you accelerate, your car’s engine is receiving a much higher dose of fuel than when at idle and conversely, when you let off the gas pedal, there is a sudden change in this fuel supply as a result of your foot letting off the pedal. When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly. I would recommend having a professional come to your location to diagnose and inspect your vehicle.

believe i have a bad power steering pump, how much does that job cost usually? now my car is having trouble starting, any relation
ANSWER : You will need to have the engine checked to see if it was a starter drive that was stuck and you burned up the starter. It may be the starter that was making the noise. I recommend having this checked by a certified mechanic to diagnose the no start, and then see if the power steering is still noisy.

Why does my car struggle to start every 4th to 5th time?
ANSWER : It sounds like your starting issues may be linked to a problem with air metering or fuel delivery. A clogged or malfunctioning idle air control valve may show some of the same symptoms you are describing. The idle air control valve can be stuck in a cold start position which may work well if the car has been sitting a few hours, but as the engine warms up there must be a regulation in airflow. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look at your hard start situation and offer a more personal diagnosis.

My Jeep started fine. I adjusted the tilt steering. The airbag light came on but it continued to run fine. Shut Jeep off and would not start again
ANSWER : The air bag light comes on when the computer detects an issue with the vehicle’s air bag safety system. This can have many potential causes, including a faulty sensor, wiring, air bag unit, computer, among other things. If you were having issues with the steering column, it may be possible that one of the airbag system components located in the steering column, such as an airbag module or sensor, has had an issue. If these components are linked to the starting system then this may be part of the reason why the vehicle is not starting. If the engine is cranking when you turn the key, then that is a good sign that the starter is getting power, so that rules out most of the no start issues related to the starting and electrical systems.
It may also be possible that the no start condition is a completely separate issue from the airbag light, as there are many things, not related to the airbag system, that can cause a no start condition. A few common non air bag related causes are issues with the fuel, ignition, or engine management systems. If any of the components to these systems, such as the fuel pump, ignition coils, or an engine management sensor, fail or have an issue, they may cause the vehicle to Retrieving the trouble codes using a scan tool capable of reading airbag system codes as they will likely shed some light on what the cause of the issue may be, or if the two are related. If you are unsure, I would recommend having a professional technician, such as one from YourMechanic, come to your location to diagnose and repair the cause of the no start condition.

Whining noise when starting and rattling while first driving
ANSWER : Hi, thanks for writing in. The whining and grinding sound when turning the steering wheel suggests a weak or failing power steering pump. This can happen when the pump is low on fluid causing it burn up or can happen when the power steering rack forces too much pressure through it as a result of the fluid not flowing freely through small reed valves in the rack. I would recommend having an expert from YourMechanic come to your home or office to confirm a diagnosis on the issue and make or suggest the necessary repairs or replacements.
