Maybe that little puddle on the road was deeper than you initially thought, or maybe you left your gas cap open in the middle of a storm – regardless, these things could happen to the best of us. Water in your engine decreases your vehicle’s performance and can leave it severely damaged. It is important to address the problem immediately to get your car back on the road.
The following symptoms will help you determine if you have water in your engine:
Abnormal or sputtering acceleration – Your vehicle suddenly increases or decreases in speed while you’re driving and sputters when accelerating.
Poor gas mileage – Your mileage-to-fuel ratio decreases when your tank has water because your engine can only burn the fuel it receives, not the water. The water may also be diluting the fuel in the engine, making it less effective.
Car stalls – If the amount of water is not too excessive, your vehicle may still perform normally; but too much water can hinder your fuel’s combustibility.
Engine won’t start – When your vehicle’s piston is submerged under water, it won’t be able to complete its rotation, which results in fuel combustion problems. This causes your engine to not start at all. In some cases, hydrolock happens because the piston rods are seriously damaged by water.
So here’s what to do after driving through water and it has entered the engine:
Don’t start the car. – Water can get into your vehicle’s components and damage it severely.
Disconnect the battery. – Disconnect the battery to prevent the electric current from damaging other electronic components.
Check fluid condition (engine oil and transmission dipstick). – Check your transmission fluid dipstick. If it’s beige in color or no longer its normal color, the oil is most likely mixed with water. Check for water droplets, too.
Inspect the air filter. – Check your air filter for water. Replace it and change the oil if the air filter is wet. Auto Parts Warehouse offers quality replacement air filters right here: https://bit.ly/2pqj3qf
Check the bumper, radiator area, and undercarriage for mud, grass, debris, dirt, and rust. – If these are present, wash and clean your vehicle as soon as possible.
Listen for unusual noises when the engine is running. – Take note of the abnormal noises that your vehicle creates when it’s running and have a professional mechanic examine your car.
Fortunately, if it’s not that serious, you can remove the water from your engine yourself. You can use a high level octane booster inside the gas reservoir to absorb all the moisture or water inside the gas tank. You may also use fuel driers that have special fuel additives and methanol if it’s only moisture.
