Hello friends, In this post let us understand what is Engine Hydrolock and its causes. Read on.
What is Engine Hydrolock?
Engine hydrolock occurs when excessive water or any fluid enters the engine cylinders. This causes the engine to stop operating. An internal combustion engine compresses the air-fuel mixture in the cylinders to produce power and rotate the crank. However, while a large amount of water/fluid enters the cylinders, the pistons are unable to compress water hence they stop working.
When does Engine Hydroclock occur?
Engine hydrolock can primarily occur at times of floods or while driving through deep puddles. These circumstances cause water to enter the engine and damage it. It is better to avoid driving in deep water puddles to prevent engine hydrolock. Moreover, always avoid trying to start your engine after an hydrolock as this may lead the pistons to suck in more water. If such a situation arises contact a mechanic immediately.
Consequences of Engine Hydrolock?
Engine Hydrolock can seize the entire engine. In worst cases, it may cause breakage of parts like the connecting rods, crank, and engine head. The higher speed of the piston traveling upwards can cause them to bang on the head due to lack of combustion when water enters the cylinders.
This requires a quick engine flush following the removal of spark plugs and fuel injectors for the water to escape. Head gasket failures may also cause a hydro lock as the coolant may leak into the cylinders.
Symptoms -
In non-critical cases, water can be seen leaving the exhaust without any engine damage.
In critical cases, a heavy engine knocking can be heard followed by instant engine damage and breakage of the engine parts (pistons, connecting rods, head, etc)
