Why is there water dripping under the car?

[OCalvin]

Reasons for water dripping under the car: 1. If it occurs after running the air conditioning for a while, it is a normal phenomenon. This happens because moisture in the cabin condenses on the evaporator and forms water droplets, which are then drained outside the car through a collection tray and drain pipe; 2. It could be due to a damaged windshield washer fluid pipe caused by scraping the undercarriage—simply replace it at a repair shop; 3. If the water is colored, it indicates a leak in the cooling system, which should be inspected and repaired. Inspection and troubleshooting methods: 1. Check if the coolant level in the radiator is low, inspect the cooling system pipes for looseness or damage, and look for any undercarriage scratches at the bottom of the radiator; 2. Ensure the coolant reservoir is not overfilled (overflow may occur when temperatures rise); 3. Check the windshield washer fluid reservoir, pipes, and connections for looseness or damage.
