With the monsoons looming over India, we will see a lot of motorists getting stuck in submerged roads. While it is best to avoid flooded roads, to protect a vehicle, it is unavoidable for many. Here is a mechanic’s advice, which can save you a lot of money and trouble. The same is applicable for cars as well!
What’s happening here?
The mechanic explains in Tamil which roughly translates to “One should never try to kick-start a bike after it is submerged in water and stops.” Trying to start the engine causes the water to be sucked in by the engine, which otherwise stops after sensing water. Kick-starting the bike causes the piston to move, which creates a vacuum inside the engine and water flows inside the chamber.
This can cause massive damage to the engine and can even make it un-repairable. The mechanic further explains that if a bike stops in water, it can be repaired for as low as Rs. 620. The charge includes Rs. 300 for two engine oil changes. The engine is flushed after filling fresh oil and then new oil is filled. He also mentions a charge of Rs. 170 charge for the new spark plugs and Rs. 150 labour charges. However, if someone tries to kick-start the bike when it is submerged in water, the repair cost can go up to Rs. 5,000 or more. The engine needs to be cleaned thoroughly from inside if the water enters the chamber. All the engine parts like pistons, piston rings and other sensitive parts like gaskets need to be changed.
The mechanic uses a Bajaj Pulsar bike for demonstration. The bike’s rider tried to kick-start the bike when it was submerged, which caused the water to enter the engine. When the mechanic unbolts the engine drain nut, which is used to drain the engine oil, water gushes out of the engine. The mechanic shows how the air filter is drenched in water and also shows that water is present in the exhaust of the bike.
He then opens different parts of the bike and drains the water out. The mechanic then fills new engine oil and starts the engine and it comes to life. It is important for any vehicle owner to understand that cranking the engine underwater can damage the engine severely and can increase the repair cost by a huge amount.
