When it comes to getting water out of a lawn mower engine, there are a few steps you can take to ensure that the engine is properly drained and ready for use again. It’s important to note that these steps are specifically for 4-stroke engines, as they require a different approach compared to 2-stroke engines.
1. Prepare for the draining process: Start by gathering the necessary tools and materials. You will need a wrench or socket set to remove the oil drain plug, a container to catch the drained oil, some light oil (such as 10W-30), and a spark plug wrench to remove the spark plug.
2. Drain the crankcase: Locate the oil drain plug on the bottom of the engine. Place the container underneath to catch the oil. Use the wrench or socket set to remove the drain plug, allowing the oil to flow out. It’s important to note that if water is present in the crankcase, it will mix with the oil and come out during this process. If you notice water coming out with the oil, it means that there is still water present in the engine.
3. Repeat the draining process: If water is present in the oil, it’s crucial to remove it completely before adding new oil. To do this, add some light oil, such as 10W-30, into the crankcase. Rock or shake the engine gently to help mix the oil and water. Then, repeat the draining process by removing the drain plug again. If water still comes out with the oil, repeat the adding, rocking, and draining steps until no water is present.
4. Drain the cylinder: Once the crankcase is free of water, it’s essential to drain any water that may have entered the cylinder. Start by removing the spark plug using a spark plug wrench. Tilt the mower to allow any water in the cylinder to drain out completely. You can also gently pull the starter cord a few times to help expel any remaining water. Once you’re confident that all the water has been drained, reinstall the spark plug.
5. Refill with fresh oil: After ensuring that all the water has been removed from the engine, it’s time to refill it with fresh oil. Refer to your mower’s manual for the appropriate type and amount of oil to use. Slowly pour the oil into the oil fill port, being careful not to overfill. Check the oil level using the dipstick to ensure it is within the recommended range.
By following these steps, you can effectively remove water from a lawn mower engine and ensure that it is ready for use again. It’s important to note that prevention is key in avoiding water damage to your mower’s engine. Store your mower in a dry and covered area, and avoid mowing wet or waterlogged grass to minimize the risk of water entering the engine in the first place.
