Experienced mechanics share their insights in answering this question :
To justify any repair expense, you first need an accurate diagnosis. It would be unusual to need a new engine, even at 150,000 miles, unless something catastrophic occurred. If the dealership did not provide you with a complete and intelligible explanation, preferably in writing if you paid a diagnostic fee, of "why" you need a new engine, I would turn your attention elsewhere and seek a second opinion and along with that second opinion, potentially lower cost repair options. If you want the issue diagnosed by a certified mechanic from YourMechanic, I would recommend that you simply request a no start diagnostic. After such a diagnostic, if it turns out that the LOWEST cost repair option for you is to change out the engine, in some locales certified mechanics dispatched by YourMechanic are available to do that. Finally, I will stress that, unless you have been told conclusively and authoritatively that major internal mechanical components of the engine are broken, and that is why the engine won’t run, you definitely should get a second opinion. That is because engines often won’t run for the simplest of reasons so you really need to get a credible and accurate diagnosis, from an expert, of the issue you are having.

How to Identify and Fix Common car Problems ?

If the tensioner or pulleys are worn or damaged, they could cause a loose serpentine belt that might just fall off instead of breaking. Poor serpentine belt tension can affect the engine accessories, and the power steering pump or alternator won`t function properly.
The short answer is yes, your car will start even if the serpentine belt is broken or missing. To get the car going, the battery sends power to your starter motor. The starter motor provides enough power to get your engine moving and the combustion process started.
If the timing belt does not move as you crank the engine, the belt is likely broken or is slipping on the gears. An inoperable timing belt will prevent the engine from starting. If the belt is moving, just be sure it has not slipped and that the engine is properly timed.
Why isn`t a car starting after replacing a serpentine belt? If it didn`t start before replacing the belt, it won`t start after replacing it, simply because the battery is still dead.
Without the belt, neither the alternator nor the water pump will be driven. That means that the car battery will run down and the engine will overheat. Once either of those things happen, you`ll have to stop driving and be stuck wherever you ended up.
It depends on what the belt runs. If it runs the water pump you won`t make it more than a few miles before overheating. If the water pump is still good you should be able to make it about 20 miles on a good battery.
You may notice your vehicle battery failing to recharge if the alternator is affected by a bad serpentine belt. Additional signs of a possibly bad serpentine belt include: Flickering lights on start up. Failure to start.
Hi – a failing idler pulley can certainly keep your alternator from charging properly, resulting in a dead battery, which would prevent the engine from starting of course.
Typically a damaged belt tensioner will not impact vehicle performance. It would cause the serpentine or drive belt to wear prematurely or to squeak – but not cause the acceleration issue.
In the technical sense, yes—you can drive a vehicle with a broken serpentine belt, but only for a short distance, as you may unexpectedly lose power at any time. If this happens while you`re on the highway, you are at serious risk of being hit by or colliding with another vehicle.
If your car`s water pump isn`t driven by the serpentine belt, you`re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car won`t run and will just shut off.
Slipping can be the result of a loss of belt tension (or a weak automatic tensioner) or pulley misalignment. When the belt slips off the track, the friction between the belt and accessory drive pulleys causes the belt to overheat. If you hear a high pitched squealing noise, it`s probably time for a switch.
It`s quite simple, really: your car cannot run at all without a timing belt. If the belt breaks while you are on the road, the car will break down immediately – and your engine can experience severe damage.
Under no circumstances can you drive a vehicle without a serpentine belt because the serpentine belt serves the important function of delivering antifreeze to important parts of the engine. The serpentine belt drives the water pump, and without it, there is insufficient coolant flow to maintain the engine temperature.

hey i had a belt break while traveling on my 2004 honda pilot. It is the small belt and not the serpentine belt. The mechanic t
ANSWER : Hello. The smaller belt is known as your timing belt, and it works inside the engine to keep mechanical components aligned with each other during the compression cycle. The serpentine belt, which is the big belt, drives the alternator, water pump, AC compressor, and a couple of other components. If the small belt broke it is likely the timing belt. This will cause the car to stall, lights to illuminate, and can even cause serious damage to the engine. Typically replacing a timing belt is a lot more complicated and expensive than replacing a serpentine belt. You may want to receive a second opinion on the car before you go ahead with repairs.

I had my truck towed on a flat bed tow truck and now it is vibrating really bad and it sounds like my tires are howling
ANSWER : The problem sounds like you have flat spots on the tires in the rear when the tow truck operator dragged and pushed the truck with the transmission locked. I would recommend having a vehicle safety inspection to see if there is tire damage or other possible damage done by the tow truck. Have a mechanic from YourMechanic come and do the inspection and check the problems for you.

I parked my truck for 5-10 mins. Tried to turn it on, now it wont start, called a tow tow truck 15-20mins later my truck turned on
ANSWER : It is very likely that you have a powertrain control module failure. This can happen often on many GM vehicles. I would recommend having the powertrain control module tested and replaced as necessary in order to resolve this issue. After the powertrain control module is replaced, a reflash procedure will be required so that the vehicle can relearn all of its primary engine data. Once the reflash is completed, your vehicle should no longer have this issue.

ANSWER : Hi there:

In cases like then when you’re not sure what component needs to be replaced, it’s always best to have one of our professional mobile mechanics complete a car is hard to start inspection first. This will allow the mechanic to review your car for damage that is causing the symptoms you’re experiencing and then recommend the right replacement or repairs be completed to resolve your issue.

(08 f150 4.6L) Truck is cutting off when making a complete stop at red light or stop sign.
ANSWER : Check the Idle Air Control (IAC) valve and see if its dirty or not functioning correctly. I recommend removing the IAC and cleaning it out. If the valve was sticking before, the computer could have caught it and adjusted the idle to accommodate the issue. After having the battery cable off, the computer is in a learning cycle which means that if the IAC is not working properly, the computer will have to relearn and may learn to shut off due to a faulty valve, even though the computer says its good. If you need further assistance with your engine stalling out at stops, then seek out a professional, such as one from Your Mechanic, to help you.

When I come to a stop my truck stalls and/or shuts off. It also idles real low at a stop 2008 Toyota Tacoma
ANSWER : Hello – first task is to check for blown fuses, failure of the cigarette lighter circuit may indicate additional wiring problems. The stalling at idle and low idle speed may indicate a failed or dirty idle air control valve or dirty throttle body condition. I recommend a poor idle inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

My 2001 dodge ram 1500 4×4 5.2 lieter blinkers brake light running lights all stopped working while driving I parked my truck and
ANSWER : This sounded confusing until I read the no bus part. If you are seeing a no bus error, this is an indication that the vehicle has lost connection with the powertrain control module. When this happens, all electronics will likely quit functioning properly. I would recommend having your powertrain control module tested by a qualified professional to determine if it is working proplerly. If not, replacement of the powertrain control module would be required in order to resolve this issue.
