How to Determine if a Car Has Water Intrusion?

[DeAddyson]

Here are specific methods and solutions for determining if a car has water intrusion: 1. Check the oil dipstick: If the dipstick is pulled out, wiped clean, reinserted, and comes out whitish, it indicates water intrusion. Solution: Replace the engine oil and oil filter. 2. Observe the oil color: If it appears milky white, it means water has entered and emulsified the oil. Solution: Replace the engine oil immediately to avoid engine damage. 3. Check for difficulty in ignition: Inspect if the coolant in the radiator is cloudy, has oil droplets, or has increased in volume. Solution: Seek after-sales service for repairs or replacement.
