Finding your car submerged after a flood is a nightmare scenario. The immediate concern shifts to “How do I even begin to fix this?”. One of the biggest problems is water getting into your engine. Water‚ unlike gasoline‚ isn’t compressible‚ and that can cause serious damage. But don’t panic just yet! While it’s a serious situation‚ there are steps you can take to try and salvage your engine. Let’s walk through how to get flood water out of your car engine and what to do next.
Assessing the Damage: Is There Flood Water in Your Car Engine?
Before you even think about starting your car‚ you need to determine if water has actually made its way into the engine. Trying to start a flooded engine is a surefire way to cause catastrophic damage; So‚ how do you check?
- Check the Oil: Pull out the dipstick. If the oil looks milky or light brown‚ that’s a strong indicator of water contamination.
- Inspect the Air Filter: A wet or damp air filter is another sign that water has entered the intake system.
- Listen for Cranking Issues: If you try to crank the engine (after checking the above!)‚ and it sounds strained or makes a thudding noise‚ stop immediately. This could mean the cylinders are full of water.
If you suspect water intrusion‚ proceed with caution. It’s better to be safe than sorry!
Step-by-Step Guide: Getting Flood Water Out of Your Car Engine
Okay‚ so you’ve confirmed water is in your engine. Here’s a breakdown of how to tackle the problem. Remember‚ safety first! Disconnect the battery before you start working.
1. Disconnect the Battery
This is crucial! Disconnecting the negative terminal prevents any accidental electrical shorts while you’re working on the engine.
2. Remove the Spark Plugs
This allows the water to escape from the cylinders. Use a spark plug socket to carefully remove each plug. Keep them organized so you know where they go later.
3. Crank the Engine (Without Starting It!)
With the spark plugs removed‚ crank the engine for short bursts (5-10 seconds each). This will force any water in the cylinders to shoot out. Be prepared for a mess! Cover the spark plug holes with a rag to minimize splashing.
Important Tip: Cranking the engine with the spark plugs removed can be messy. Make sure you have adequate ventilation and wear eye protection!
4. Change the Oil and Oil Filter
Even if you drained the oil earlier‚ there’s likely still water contamination. Replace both the oil and the oil filter to ensure you’re starting with a clean slate.
5. Check and Clean the Air Intake System
Remove and inspect the air filter. If it’s wet‚ replace it. Also‚ check the air intake tube for any debris or remaining water. Clean it thoroughly.
6. Reinstall the Spark Plugs
Once everything is clean and dry‚ reinstall the spark plugs. Make sure they are properly torqued.
7. Reconnect the Battery
Reconnect the negative battery terminal.
Preventing Future Issues: After Getting Flood Water Out of Your Car Engine
Getting the water out is just the first step. You need to take precautions to prevent long-term damage.
- Check All Fluids: Besides the oil‚ check the transmission fluid‚ brake fluid‚ and coolant for contamination.
- Inspect Electrical Components: Water can corrode electrical connections. Check wiring harnesses‚ connectors‚ and fuses for damage.
- Dry Out the Interior: Mold and mildew can quickly grow in a flooded car. Thoroughly dry the interior‚ including carpets and upholstery.
Consider having a mechanic inspect your car to ensure there are no hidden issues. A professional can check for things you might miss.
Pro Tip: Consider using a dehumidifier inside your car to help dry out the interior and prevent mold growth.
When to Call a Professional: Is it Worth Trying to Get Flood Water Out of Your Car Engine Yourself?
Let’s be honest‚ sometimes DIY isn’t the answer. If you’re not comfortable working on cars‚ or if the flooding was severe‚ it’s best to call a professional mechanic. They have the tools and expertise to properly diagnose and repair any damage. Think of it as an investment in your car’s longevity.
Here are some situations where a professional is definitely recommended:
- If the water level was above the dashboard.
- If you suspect significant electrical damage.
- If you’re not comfortable performing the steps outlined above.
