What Causes Water Leakage in a Car?

[RichardDella]

Reasons for water leakage in a car: 1. Condensation water dripping from the air conditioning system in use; 2. Malfunction of the radiator cooling system causing water leakage under the car; 3. Possible windshield washer fluid dripping. Inspection and troubleshooting methods: 1. Check if the radiator coolant is insufficient, then inspect whether the cooling system pipes are loose or damaged, and examine if there are any scratches on the bottom of the radiator; 2. Ensure the coolant reservoir level is not too full, as it may overflow when the temperature rises; 3. Check the windshield washer fluid reservoir, pipes, and connections for looseness or damage; 4. Determine if the dripping is caused by prolonged use of the air conditioning on hot days, leading to condensation water drainage, which is a normal phenomenon.
