Why is there water leaking from the front of the car?
2 Answers
The reasons for water leaking from the front of the car are: 1. Condensation water dripping from the air conditioning system in use; 2. Coolant system failure in the radiator causing leakage; 3. Windshield washer fluid dripping. Inspection and troubleshooting methods: 1. Check if the radiator coolant is low, then inspect the coolant system pipes for looseness or damage, and check the bottom of the radiator for scratches from grounding; 2. Ensure the coolant reservoir level is not too full; 3. Inspect 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, leading to condensation water drainage; 5. Check if the leaking water is colored, as colored water indicates a leak in the coolant system, which should be repaired.
A few days ago, my car started leaking water from the front, which really worried me. Later, I figured out that the most common cause is the drainage of condensation water from the air conditioning system. When driving with the AC on in summer, the compressor turns moisture in the air into water droplets, which then flow out through a drain tube under the car—this is completely normal, just like how a room AC drips water. However, if the leaking fluid isn’t clear but has color, you should be alert. For example, green or pink liquid might have a sweet smell, indicating a coolant leak, likely due to a damaged radiator or cracked hose—this is serious. If left unfixed, the engine could overheat and fail on the highway. On the other hand, if it’s blue, it’s probably windshield washer fluid leaking from a cracked reservoir, which isn’t a big deal but needs topping up. My advice is to park, turn off the AC, and wait half an hour to see if it still leaks. If it stops, no problem; otherwise, it’s best to get it checked by a professional shop to avoid minor issues becoming major ones—safety first!
