There are different types of malfunctions in cars. Some we notice right away. For example, if the engine stalls, the starter stops turning, the power windows or central locks don’t work, fuses blow out, or a light bulb doesn’t light up—we take immediate action. But we simply do not notice many malfunctions that arise gradually. The repair of the hood lock can be attributed to just such a case.
Most often, breakdowns occur on the road.
The hood lock is one of the first places on the list of “gradual” breakdowns. In rare cases, it breaks suddenly (it worked perfectly and suddenly...). The deterioration of its work manifests itself, so to speak, step by step. Well, he slammed the hood again, slammed it again with more force. It finally closed, well, okay... Yes, the hood closed, but was it secure? Won't this little thing cause trouble for the careless car owner? As you know, in most cases, danger creeps up from the side from which it is not expected.
The hood is no joke
Hood lock VAZ 2109
There was a need to open the hood of the Nine, I pulled the handle from the passenger compartment and felt that something was wrong. Usually you pull the handle and hear a click, but now there was no click and the handle was difficult to pull. I leave the cabin, go to the hood and open it. I see a hood cable with a broken spring. Everything is clear, the hood lock spring has broken. It's very easy to change it. We buy a new spring.

First, we take out the old broken spring.

Then we insert a new one and first of all we put it on the cable as shown in the figure. Now you need to insert the second end of the spring into the locking hole.
The hood won't close
Okay, everything turned out quick and easy. I close the hood, but it doesn't latch. It is necessary to adjust the protrusion of the spring with a screwdriver and lubricate the contact point with machine oil - in order to pull the handle out of the hood with less effort.

After this, you need to develop a hood lock - open and close it several times. Now the hood latch has been adjusted and designed to keep the hood securely closed when the car is moving. The hood of the car is equipped with a special latch that will prevent the hood from opening if the hood latch opens while driving.
Hood safety latch
If this safety latch did not exist, then when the hood latch spontaneously opened with a gust, the hood would open while driving.
In what cases will adjustment help?
Let's list the main malfunctions that you can fix yourself by just adjusting the car hood lock:
- The hood has become difficult to close; it requires repeated slamming and significant force to close it
- It has become problematic to open it (we pull and pull, but the reaction is zero)
- Doesn’t “bounce” when the cable is pulled; when closing, an extraneous knock of metal on metal is heard
- Rattling when the engine is running, in the pits.
Replacing the hood lock on a VAZ-2109 - we solve the problem ourselves
The variety of cars on the roads of our country can capture everyone’s imagination. However, among our car enthusiasts there are those who would never trade their beloved “nine” for anything. Indeed, the VAZ-2109 rightfully deserves to bear the title of cult, because many of us gained experience behind its wheel. However, we should not forget that at first universal love was very difficult for the car. Not least because of trivial problems with the trunk and hood locks. What can we say, many VAZ-2109 owners still repair these car parts, sparing neither effort nor time.
Replacing the hood lock on a VAZ 2108, VAZ 2109, VAZ 21099
Welcome! Before we start replacing the hood latch, let's take a look: What is included in the so-called hood latch? Firstly, the castle includes:
• Two hood release handles. (One handle is installed in the cabin, and the other is located in the engine compartment)
• The lock also includes the lock drive cable itself, as well as the hood latch and safety hook. Read below for all the instructions for replacing lock components.
Note! When replacing the hood lock, you will need a screwdriver, as well as wrenches and thin pliers!
Summary:
When do you need to change the hood latch components? • For example, the handles used to open the hood of a car must be replaced if they break or are otherwise deformed, making it difficult or even impossible to open the hood of the car.
• The lock drive cable must be replaced if it is broken or deformed, due to which it will also be impossible to open the hood of the car.
• The hood latch and the lock spring need to be changed if they are also deformed, because as a rule, if they are heavily worn or distorted, the hood of the car can spontaneously open while driving.
How to replace the hood lock elements on a VAZ 2108-VAZ 21099?
Replacing the lock spring:
1) To remove the lock spring, first disconnect the drive cable from it.
2) Then use a screwdriver to pry it up and remove it from the car body.
Note! To install a new spring in place of the old one, do the entire operation in reverse order!
Replacing the lock drive cable:
The lock drive cable can be removed without removing the spring, to do this:
1) First, remove the drive cable from the fastening lock.
2) Then move into the car interior, and then unscrew the bolt that secures the hood release handle.
3) Next, remove the lock handle and, using pliers, straighten the end of the cable.
4) After straightening the end of the cable, slide the metal sleeve up.
Note! When the bushing is moved, remove the cable loop from the lock handle!
Hood modernization and maintenance
In order to make the hood operation even more convenient, you can install a gas stop on it, which ensures almost automatic opening.
For this you will need:
The installation is performed like this:
- Open the hood and put it on the stop.
- Drill 4 mounting holes, measuring 530 mm on each side of the hood (the distance between the holes themselves will be 310 mm). In this case, two holes should be drilled in the body and two in the hood itself (it is important not to overdo it and not drill through it).
- Carefully coat the holes with bitumen to prevent corrosion.
- Place the gas stop in place and secure it with bolts.
- Install the second gas stop in the same way.
As you can see, this operation is also quite simple and will not cause any particular difficulties. At the same time, such tuning can be very convenient - the hood, equipped with gas stops, will open on its own after a slight push by hand, and when closing it will lower smoothly.
Hood lock failed
There are different types of malfunctions in cars. Some we notice right away. For example, if the engine stalls, the starter stops turning, the power windows or central locks don’t work, fuses blow out, or a light bulb doesn’t light up—we take immediate action. But we simply do not notice many malfunctions that arise gradually. The repair of the hood lock can be attributed to just such a case.

The deterioration of its work manifests itself, so to speak, step by step. Well, he slammed the hood again, slammed it again with more force. It finally closed, well, okay... Yes, the hood closed, but was it secure? Won't this little thing cause trouble for the careless car owner? As you know, in most cases, danger creeps up from the side from which it is not expected.
Problems with the hood latch
What functions does the hood lock perform?
The main purpose of the hood lock is to keep the car's hood closed in any conditions (whether the car is parked or rushing along the highway at a decent speed).
Yes, most designs are not satisfactory, but they (over time) do not provide adequate safety. The main thing is to catch the moment when such “nonsense” as the hood lock should be replaced or repaired.
What he shouldn't do
You are just starting to have problems with your car's hood lock if:
- To close the lock, you have to slam the hood several times, each time applying more and more force.
- The hood rattles and “bounces” on potholes
- It became problematic to open the hood, the handle in the cabin does not respond well.
If you are familiar with these inconveniences, then it’s time to think about adjusting, replacing or repairing your car’s hood latch.
Timely diagnostics and repair of vehicle components will save you from problems and unnecessary costs of time and money.
Replacement, repair or adjustment?
To begin with, let’s define the problem that has arisen and the scale of the upcoming work.
- If the lock jams occasionally, and the hood rattles noticeably when the engine is running, then a simple adjustment will help.
- If there is constant jamming and futile attempts at adjustment, the locking mechanism or cable drive requires repair or partial replacement
- In case of very serious damage (warped, crumbled, etc.), only a complete replacement will help.
Using a superficial inspection method, you can determine whether a given device requires replacement or can be repaired. Let’s say that after an examination we determine that “the patient is more likely to be alive than dead,” and he can still be resuscitated.
A few more common installation-related features
The effectiveness of the hood lock sometimes greatly depends on the professionalism and conscientiousness of the installer (you can depend on working conditions and much more, but it seems to me that everyone understands what we’re talking about). This is a general rule for all universal designs; nothing can be done about it.
For mechanical models it is desirable:
Ensure the secrecy of the installation of the larva. The point is not even to hide the larva itself, but to prevent the attacker from getting to the armor and getting the cable.
Hood lock repair
There are about as many modifications to hood latches as there are car models. If you have problems with its operation, first of all you should understand the design features of this mechanism.
Hood lock device
On almost all cars they are mechanical, and consist of similar main parts. Let's take a closer look at this device using the example of the VAZ-2109, since the hood of this car has a bad habit of opening while driving.
- Latch pin
- Bottom cup
- Safety hook
- Lock washer
- Hook spring
- Hook axis
- Upper cup
- Latch spring
- Rod shell bushing
- Handle axis
- Lever
- Rod seal
- Sheath thrust
- Rod holders
- Lock spring.
There are a lot of details, but the principle of operation is clear. When closing the hood, the pin enters the hole in the frame and is secured by the lock spring. By pulling the rod handle, we release the pin. A gap forms between the hood cover and the car frame. The hood is held only by a safety hook, by pressing which we open the lid completely. Difficult? Yes, it’s much easier, I pulled the “string” and the door opened!
Let's start repairing the castle. All we need from tools are several keys (at “13” and “19”), a flat-head screwdriver and pliers (preferably thin ones). This can be found in any car or garage.
Replacing the lock spring
As we can see, practically the only element of the locking mechanism on the frame is the metal lock spring. It turns out that she is the main culprit for the spontaneous opening of the hood!
Metal, as you know, “gets tired” over time. Timely replacement of the spring can save the car owner from a lot of trouble.
So, let's change the spring!
First of all, disconnect the drive rod from the spring.
Using a screwdriver we release...
And remove the spring.
Three movements and you're done! Installing a new spring occurs, as you may have guessed, in the same way, only in reverse order.
We've sorted that out, let's move on. Have you ever encountered such a situation? When you pull the handle in the cabin, you can clearly hear the click of the hood lock. You get out of the car, but the lid does not open, there is not even a gap where you can insert your fingers. Here you can’t do without an assistant; one pulls the handle, the other tries to lift the hood lid. If adjusting the latch position does not help, the spring is again to blame (responsible for the “bouncing” of the lid). Only this time it is already on the latch pin.
What are sports locks?
What are their functions?
Many people who saw strange, symmetrically located devices on the hood of a car for the first time had a similar thought: “What can people come up with to stand out from the crowd!”
Yes, these accessories really give the car a new, sporty, aggressive look. That's all? Is it worth it to poke holes in the hood for the sake of a dubious change in appearance? In fact, sports hood locks, in addition to decorative functions, perform another important role.
Driving safety
It is not uncommon for a car to open its hood while driving. And this happens not only with “old” vehicles. It’s good if everything gets done by replacing the hood, windshield, straightening the roof, followed by paint work. All this costs a lot of money and, most importantly, nerves. How to insure yourself against similar and more serious troubles?
Additional hood locks of this type are designed precisely to prevent such situations. These were developed for racing cars, and now no sports car will be allowed to participate in a rally without them. An open hood, and even on a race track... This is where they got their name, and are now known as “sporty”.
