Boats are made to deal with water while cars don't. But, what the water can do to a car? Water can wreak havoc inside a car, especially damaging the engine.



Water can rust exposed parts quickly, endangering the engine in the process. Usually, when a car crosses a puddle, it must deal with water. In the event that water enters the vehicle through the hood, it might have an impact on the engine components. A car may experience hydrolock, or more specifically, hydrostatic lock, under certain circumstances.

Although it's generally uncommon, hydrolock can cause substantial damage with an engine's internal parts and, in the worst cases, can even render an engine irreparable. Fortunately, most motorists will never experience a true hydro lock situation. But those who do won't forget it anytime soon.

It is definitely going to fruitful look at inside story and the root cause of hyrdo lock, more specifically avoid such a situation happening with your car.

What does Hydrolock signify?

The word Lock means no further movement or action when it comes to the automobile. The hydro lock is simply a situation when car gets halted when there is an entry of water inside the combustion chamber.



Fluid, especially water presence is not a good sign inside the engine. It is incompressible and when pistons found this inside combustion chamber, they are unable to complete the stroke. Therefore, engine comes to a halt when one or more piston finds them in such a situation.

This definitely summarizes the engine hydro lock. However, hydrolock may happen in any state whether your car is running or idling. However, a hydorlock might be a risk when it occurs during an active state and often damage a lot of components inside the engine.

Assessment of damages due to a hydrolock

However, Hydrolock is not a complete safety feature against water interference inside the engine. But the extent of damage usually depends on the engine speed.

1. At low RPMs or while idling

If water goes inside the combustion chamber when your engine is at low RPMs, there is less probability of damage. However, you have to deal with a stalled engine, which requires an immediate car engine repair for hydrolock.



In case you are looking for car engine repair then we would like to recommend Service My Car to get the best car engine repair for your car in the town.

If there is any delay, rust may emerge at internal parts and turn them into useless pieces of metal. This requires a car recovery service, especially from a trusted service center.

2. At higher RPMs or while cruising

In case your engine is running at higher RPMs or cruising through the roads, it would definitely have detrimental effects.



Usually, there is always a force behind a running piston, especially when the engine is running at high RPMs. Once hydro lock occurs, a collision happens inside the combustion chamber when the piston hits uncompressed water. The collision might result in catastrophic damage, including the cracking of the rod, crankshaft, or even the cylinder walls.

In the worst case scenario, an engine running at top speed could have the piston rod smash straight through the engine block. In extreme conditions, a hydrolock is rare but not impossible.

Even when the engine is not running, hydrolocking can happen. Such things happen during the floods. While the engine is not running and the starter cannot turn the engine over, fluid fills the cylinders. The only damage you might experience in this situation is if the fluid isn't removed right away and the engine corrodes.

However, a hydrolock might damage an engine or specifically its cylinder to such an extent that you will only be able to spare from it after a complete engine overhaul.

Possible causes of water entry into the engine

Flood or more specifically water is a genuine cause, but it is not only reason, coolant might take a route inside the combustion chamber, it happens due to a worn head gasket.



In most cases, water enters through the air intake. A car's air intake system might suck up the water if it is completely immersed.

Sometimes, it came to our attention that excess oil might create a situation that could force a hydro lock. This happens due to carburettor failure or defective fuel injectors filling up the combustion chamber.

Diesel engines usually experience such incidents more as they contain high pressure fuel injection pumps.

However, you can avoid the hydrolock by just getting your car's head gasket replacement at Service My Car if the water is not the primary culprit.

Besides, you should always try to stay away from the puddle or any other water source while driving. Not just hydrolock or damage to engines, water may cause other damages to a vehicle, such as premature corrosion, electrical shorts, contaminated fluids, etc.

However, if you need any roadside assistance while dealing with such a situation, just call Service My Car. Besides, you can book a car service or order a car repair quote on our website or app online.

For an air conditioner, a compressor appears to be the most important component. But, a compressor cannot do anything if there is no refrigerant at all. There is a need to understand the importance of refrigerant inside an air conditioner.



Your air conditioner is just a fan without presence of refrigerant. However, low level of refrigerant cannot provide enough cooling while it might hurt a number of things inside your cars air conditioner.

How Does Refrigerant Assist In Cooling Air?

Air conditioner refrigerant behave like a magical substance to aid air conditioning to make cooling possible. Refrigerant does it work during a cycle of transformation from liquid to gas.



It involves several components to produce the required cooled air inside a car. Refrigerant goes through the compressor where it is compressed into liquid from gas before being sent into the condenser.

A condenser is a structure of several tubes where the refrigerant circulates and comes into contact with the fresh air. At this point, the refrigerant has a high temperature while fresh air tends to absorb the temperature by the heat exchange between the refrigerant and fresh air.

The low-temperature refrigerant is now in the dryer, where it experiences the evaporation of moisture and attains the cold state. It then passes through the orifice tube, or expansion valve. The procedure lowers the fluid's overall pressure, enabling the fluid to move to the evaporator. It is now time to enter the evaporator. The evaporator will draw air from the car, which will enter the evaporator core. The refrigerant temperature is currently lower and it can turn the heat that air carries, into cold air.



Next, the cold air travels to the passenger seats with the help of fans. Here, the moisture is also removed from the air and it allows you to enjoy the fresh and dry air. As the liquid refrigerant in the AC system turns receives heat after working, it again turns into a gaseous state.

Then, the next cycle occurs, and air conditioning happens continuously. As this is evident, the refrigerant is a major source of cooling. But, what happens if it goes out of quantity? It means, does a low level of refrigerant provide proper cooling or does it hamper the cooling system component? Let's try to find the answer to these questions here.

Does A Low Level Of Refrigerant Produce Proper Cooling?

It is unfair to expect proper cooling from a low level of refrigerant. However, the refrigerant stays for the whole life of the cooling system until there is any kind of leakage.



A compressor often senses a low level of refrigerant and does not engage with the engine for further processing. However, this is hard to recognize at a low level of refrigerant. But, if the compressor refuses to work and the air conditioner fails continuously to cool the interior, you should look for an inspection or possibly a car AC repair service.

However, the low level of refrigerant might be dangerous to a number of components inside the air conditioning system. Here, you know about the possible damage. A low level of refrigerant may damage your air conditioner significantly.

Persistent Presence of Icing in the Evaporator Coil

If there is any sign of icing in indoor evaporator coils, there is a low level of refrigerant to blame. It is challenging for the coil to absorb enough heat to warm the cold refrigerant at the lower refrigerant levels. This leaves refrigerant unused and too much cold, while system expect a warm state of refrigerant.



The performance of your unit will be hampered if your refrigerant is too cold because it will cause moisture to freeze on the coils' surface.

Low Refrigerant May Cause Compressor Damage

Since the compressor does possess a motor, this motor needs to be cooled down by the refrigerant. However, a low level of refrigerant fails to do so, and the engine ends up in a heated state eventually.



It typically takes some time for a low refrigerant to eventually result in the compressor burning out. Repairing the compressor, though expensive, is necessary for the AC to work. As a result, you must have the low refrigerant problem fixed by an expert if you want to avoid the situation.

Extra Burden on the Engine

Although it might not matter, there is an association between low refrigerant levels and engine performance. This makes it clear why cooling takes longer when a compressor operates on a low level of refrigerant than at a higher level.



This ultimately puts more strain on the engine and requires more work.

High Cabin Temperature

Since heat exchange is the refrigerant's main function, this is unavoidable. The efficiency of the AC's ability to produce cold air decreases as the refrigerant level drops. Under these conditions, the compressor fails and the unit begins to blow out slightly warm air when there is a significant drop in the refrigerant level.



Service My Car also provides the service for all car brands in the Dubai area, like Audi, Bentley, BMW Dubai, Jeep Dubai, and almost all other brands, all you need to do is make an online booking through the app or website.

These are the pitfalls of a low level of refrigerant. However, it is necessary to be attentive when there is a dip in the cooling inside your car. However, you can go for a professional inspection by an expert at Service My Car to be sure about the issue.
