Hydro Locking: What is it?
Knowing the inner workings of internal combustion engines, everyone knows metal, fire, and water are not compatible. Hydrolocking is a problem that can occur when you try to drive through large puddles.
Hydrolocking, also called “engine lockup” An engine that is unable to move due to excessive water in the cylinders can seize and cause it to stop moving. An internal combustion engine compresses air and functions just like an air pump. Water, on the other hand is incompressible and prevents pistons from reaching the top of the cylinders. Water resists more than the engine components can handle. This causes the motor to stop moving and affects its rotating assembly.
Accidental water in the engine’s combustion chambers is the most common cause of hydrolocking. Hydrolocking can also occur if coolant is allowed to get into the engine cylinders due to mechanical failure.
Hydrolocking can happen with stationary and running engines. Hydrolocking can occur with both stationary and running engines. This causes internal parts to fail, and the engine to suddenly stop. However, it’s almost impossible to restart a stationary engine when water has entered its combustion chamber.
What Kinds of Damage Does Hydro Locking Cause
Although hydrolocking may cause damage to several components, there are rare instances when no damage is visible. Hydrolocking’s impact on engine performance is directly proportional. Hydrolocking can be devastating if the engine runs at a faster speed.
When a lot of water gets into the cylinders, especially with a high-powered engine that is running at high speeds, it can cause serious damage. When an engine suddenly stops, the momentum from the rotating engine component is often absorbed by its weakest part. This can cause the component(s) to be damaged or deformed.
These are some of the most frequent types of damage that hydrolocking can cause.
- – Broken or bent piston rods
- – Pistons and piston rods that have pierced the engine block.
- – Cracked cylinder head
- Cracked engine block
- – Damaged crankshaft
- – Scattered balls
Hydro Locked Engine: Signs and symptoms
Hydrolocking symptoms can vary depending on how the engine is operating. Hydrolocking symptoms can be quite severe depending on the engine’s operating conditions. The most common symptoms include:
- Sudden engine stoppage
- – Unusual spray of liquid from engine
- Engine not running
- – When trying to start the engine, a sudden “thumping sound” occurs
- – More engine knocking and more engine impact sounds
Engine Locking Causes
1. Water entering the Cylinders
Hydrolocking can be caused by water from the outside entering one or more of engine cylinders. This can often happen when the vehicle is subject to floodwaters. The intake manifold can allow water to easily get into one or more cylinders.
Hydrolocking can also be caused by modifications to the intake manifold. Vehicles with cold air intake are more likely to experience these problems. The reason is that cold air intakes are open air intakes instead of closed filters. Hydrolocking could be caused by even small amounts of water being pumped to the area around the cold intake. This type of modification requires drivers to be aware that they will be walking in the fire line when driving through any puddle.
Hydrolocking can happen with running engines as well as non-running ones. However, the damage that results from hydrolocking is directly proportional in terms of the engine speed. It is best to not start an engine if it has hydrolocked while it is running.
2. Coolant in the Cylinders
Hydrolocking can also occur when coolant is infiltrated into cylinders because of mechanical failure. This is usually caused by a defective cylinder head gasket. A faulty cylinder header gasket can leak coolant through the engine’s waterways and into one or more cylinders. Engine damage is more likely when the engine’s not running. However, if the coolant is not leaking into thecylinders, the engine should be able start.
Hydrolocking can also be caused by fuel leaks and injectors that are left open, although this is rare.
Can Hydrolocking Cause Engine Damage?
There are many factors that will determine whether a hydrolocked engine is repairable. These include the engine’s operating state when hydrolocking happens, the number affected cylinders, and the extent of damage that occurred during hydrolocking.
The engine may have suffered severe damage if a piston rod or piston is protruding from either the oil pan or the engine block. This is not something that can be repaired. A complete engine replacement may be necessary in these cases.
The engine can still be salvaged if there is no water in the engine or damage to its internal parts. All spark plugs should be removed, and all spark plug holes must also be cleaned. You should inspect the engine for any damage and, if necessary remove the intake manifold or cylinder head. Replace any leaking coolant from the engine cylinder head gaskets that are defective. Hydrolocking is therefore avoidable.
