Why is there water dripping under the front of the car?

[ZaneDella]

There are three possible reasons for water leaking under the front of the car: 1. The air conditioning is on. If the air conditioning is on, then it's condensation water from the AC system, which is normal. 2. The defroster or defogger is on. In this case, the compressor will operate, causing water to drip underneath, which is also normal. 3. The radiator is leaking. This situation requires repair, either by welding the leak or replacing the radiator. Inspection and troubleshooting methods: 1. First, check if the coolant in the radiator is insufficient, then inspect the cooling system pipes for looseness or damage, and check if there are any scratches on the bottom of the radiator. 2. Ensure the coolant reservoir is not overfilled (it may overflow when the temperature rises). 3. Check the windshield washer fluid reservoir and its pipes and connections for looseness or damage. 4. Determine if the dripping is caused by prolonged use of the air conditioning on hot days, resulting in condensation water drainage (this is normal).
