That's why a picayune preventive maintenance is always the best thing to do to proceed your car running smoothly. Nevertheless, sometimes that's easier said than done and nosotros let things slide.  Other times things merely happen randomly even when we have been doing our best to take care of a vehicle.

Motorcar Repairs Are EXPENSIVE

 A seized engine, or a locked-up engine, is definitely one of the most annoying bug that you can deal with as a driver. Y'all put your key in the ignition to try to showtime your car and the engine doesn't turn at all. You might hear a clunking sound at offset and then the car stops dead and nothing happens from there. This could fifty-fifty happen when y'all've got a brand-new battery and a full tank of gas.  A seized engine is caused by some kind of mechanical failure, usually having to do with oil , but not ever.

Let'south take a expect at some of the signs and symptoms of a seized engine, what causes information technology in the starting time place, and what you lot can do about it.

Signs and Symptoms of a Seized Engine

When your engine is virtually to seize up on you, the nearly prevalent sign y'all're going to experience is the sound it makes. Before it seizes completely you should be getting these alert signs that warning you to a problem so hopefully, you'll have an opportunity to fix information technology before information technology gets too bad. However, we know that's not always the instance. Still, if y'all're noticing any of these signs, you should practice what you tin to deal with information technology every bit quickly as possible.

 Knocking Sound

Your engine is going to brand some distinct noises when it gets bad enough that the danger of locking upward on you is present. Before it fully locks up, yous should hear some loud clunking, banging, knocking sounds that come from the engine.

As the situation gets worse the sounds will besides get worse. You'll hear a metal hitting sound, sometimes known as dead knock. This is the sound of the piston rod banging into the crankshaft and it is extremely bad.

 Fumes

If you're noticing smoke and a odour coming from your engine, and especially if information technology happens to catch fire on you, then y'all could certainly be dealing with a seized engine. If your starter is unable to get the engine going because it'south locked up on you lot, parts will begin to overheat including the wires. This can cause fume and potentially even a fire, especially if your engine is covered in oil and droppings.

Check Engine Lite

Even though a cheque engine light can come on for 101 different reasons, if yous're experiencing those noises we mentioned and the cheque engine light comes on you lot can well-nigh guarantee that your engine is experiencing some serious issues and will need to be serviced quickly before it completely locks up on you and renders your car useless.

Full Engine Failure

The finish issue of all of these symptoms if they're not addressed shortly enough is that your engine volition stop working entirely in your machine. Ideally, yous'll be able to take hold of information technology before it gets this far, but that's not always the case. When your engine has fully locked and failed nothing is going to get it started again. Y'all volition still have command of the electric organization, meaning y'all'll be able to utilize your lights and your radio, simply you lot won't fifty-fifty hear the vehicle attempt to creepo and turn over.

What Causes an Engine to Seize?

There are several reasons that your engine might seize up on you lot and cause this level of damage.

Water

Believe information technology or non, h2o is 1 of the reasons that an engine is going to seize up and cease performance.  Once information technology's in your cylinders, water is not compressible in whatsoever way and does not mix with the fuel and oxygen in your car at all. A serious leak of some kind could allow water to get into your engine but that is extremely unlikely. More than frequently, this is caused by risky driving such as when you try to head downward flooded roads.  Water is pulled in through the intake valve and causes what is known as hydrolock in your engine.

If you've ever seen videos of people in alluvion weather condition trying to manage water that gets up over in the front grill of their vehicle, you likely would accept seen the cars stall out in the middle of the road as well. That'southward because water ended up flooding the engine, which prevents the combustion reaction and also can strip abroad the oil making the entire engine useless at that point. Keep that in mind if yous're ever in flood conditions, if the water gets upward over the tires of your vehicle, it is much too unsafe to drive.

Rust

This is much more than likely to happen with an older car that'southward been sitting effectually for too long. Over time wet will accumulate naturally, but from condensation in the air, and if a car sits for an extended flow of time without being used, parts of the engine will terminate upward corroding. The pistons in particular, and the valves and the cylinders can build up a layer of corrosion that spreads from ane part to the other. This makes information technology all but impossible to get the engine started over again as a effect.

Mechanical Failure

Although not mutual, it's non unheard of for some parts to have been machined incorrectly. Your engine relies on numerous moving parts to office properly. If something was made with a fault in it, fifty-fifty a hairline fracture, over time the stress and rut from running your engine can put more than pressure on that error until information technology finally fails. As unlikely as it seems, this is too the driving force behind many vehicle recalls. Manufacturers volition consequence a remember when they larn that some of the parts used to make a automobile have suffered manufacturing defects, then you lot can accept the vehicle back in to get the role replaced costless of charge and forbid further impairment. Since these are the error of the manufacturer, they do often endeavor to accept care of these when they realize the problem is big enough.

Fuel Vapor

Hydrolock is what happens when you lot take water flooding your engine, but vapor lock is what happens under extreme estrus circumstances and another conditions. The fuel that is in the lines between the fuel pump and your engine volition really turn to vapor because the heat of your vehicle, sometimes caused by extreme estrus and outside atmospheric condition, has caused it to vaporize. This can happen just about anywhere, even parked in your parking infinite or waiting in traffic. Your fuel pump is unable to move fuel vapour because your fuel has substantially boiled in the lines.

Oil

A lack of oil is likely the most common cause for engine lock to occur. If you don't maintain a regular schedule of oil changes , the level and quality of your oil will subtract dramatically. This causes excessive friction between the metallic parts in your vehicle which leads to that knocking audio that we mentioned earlier. When it's left to get for a long enough catamenia of time then your engine seizes up because there'due south simply no more than lubrication betwixt the parts any longer.

 How Do You Unlock Your Engine?

Fixing an engine that is seized up on y'all depends heavily on the reason that it stopped working in the first place.  Some of these fixes are easier than others, and some of them are going to leave your engine permanently damaged.

Fixing Vapor Lock:   Vapor lock does not happen in most new cars because of the way modern fuel injection works, just if you still take an older vehicle with a carburetor so this might exist an issue for you. There are a few quick fixes you lot tin try to get your automobile working once again if you're suffering this trouble including pouring cold h2o over the fuel pump and fuel lines when your ignition is off. This volition cool things down and allow the fuel to condense to a liquid form once again.

At this betoken you can attempt to kickoff the vehicle again advisedly by turning the fundamental and very slightly pressing the accelerator. Keep this going until y'all get it simply started and you'll feel a fleck of sputtering as the vapor gets cleared from the lines.

Fixing Hydrolock:   Fixing a hydrolocked engine is a more difficult job than fixing a vapor locked engine. You have to remove all the h2o from the cylinders for this to piece of work, meaning you need to get the spark plugs out and stale off or replaced. The cylinder walls should be fine if you lot clear upwards the water as before long every bit possible after it becomes flooded, merely if information technology sits as well long you may have corrosion issues to worry well-nigh as well. You're going to desire to accept out the spark plugs and creepo your engine right away to pump the water out of the cylinders. Once y'all get all the water tuckered from the engine, the spark plugs may take to be replaced, you'll need to practice a full oil change as well to become whatsoever water out of the oil.

It's also possible that if your car was fully running when information technology got flooded, which is to say you collection down a flooded road or through a deep pool pulling water into the engine that the entire engine is going to demand to exist taken apart and stripped down. Each individual function will need to be cleaned out and inspected to make sure that you don't have any bent connecting rods, cracked pistons and so on. As you can tell from the sound of things this is not going to be a cheap chore at all. If you require a full repair of a hydrolocked engine y'all may end up paying anywhere from $3,000 to $viii,000 to get the job done.

Fixing an Engine That Has Sat Likewise Long : If your engine is frozen because the automobile was just sitting too long and some internal parts ended upward rusting in identify, it's possible that this could exist fixed with a little oil. You can remove the spark plugs , fill the cylinders with oil, and let it sit for a few days. You can and so effort to starting time the engine up with a breaker bar. If information technology gets going again, and so you're good to go. If not, y'all may demand to rebuild or replace the entire engine.

 The Bottom Line

As you lot tin can meet a locked-up engine is something you absolutely want to avert. Aside from the inconvenience of your auto not working properly, the price of having to rebuild or supersede an entire engine that can't be repaired is sometimes more than expensive than buying an entire new car. The best thing you can do when information technology comes to engine lock is head information technology off at the pass and forestall it earlier it starts. That means making certain that yous proceed upwards with your schedule oil changes, oil typically has to be changed every 5,000 to vii,500 miles although yous should check your owner's transmission to find out what works all-time for your vehicle.

 In addition, you want to make certain you're never driving into risky situations like flooded roads. If a road is clearly flooded out your best bet is to drive around to higher ground than risk trying to go through h2o that may end up causing your engine to hydrolock and leaving you stranded in a dangerous situation. Not only do yous accept to deal with a frozen engine, yous may accept to bargain with dangerous alluvion conditions also every bit information technology'southward simply not worth it.
