Car Leaking Water - Common Causes and Repair Solutions Guide (2024)

Are you tired of spotting liquid leaking from under your car? If you are a new car owner, you might worry but in most cases. If its car is leaking water, stay relaxed. Sometimes this issue can be a bit serious. If you spot puddles of oil, or coolant fluid, seek help from professionals.

Even though car leaking water is not toxic or harmful, you still have to check for the reasons which lead to this. Wet patches on the upholstery often leave stains and it can be frustrating to get rid of.

When Does It Leak?

Before you take any step, shortlist the symptoms that you are experiencing with your car. Look for the damp patches inside your vehicle for assurance.

After this step, try to notice whenever this symptom arises. This can help you find the actual reason for the leakage. Make sure you also monitor when it starts leaking.

During Rain:

Water leakage during rainfall is quite a common cause. In case you are planning on doing a full inspection, ensure that nothing is left open. Even if your window is open slightly, it can let a substantial amount of rain inside the car. Start the inspection once everything is sealed uptight.

If the rainwater is hitting the inside of the car, its probably because of these faulty parts:

• Sunroof drain
• Window seal
• Door weather stripping
• Cabin air filter
• Door membrane
• Windshield rubber

Check thoroughly all these parts for any sign of damage or dampness. In case you find the fault, go to your nearest car service provider to get it fixed.

Parked on a Slope:

Is the leak getting worse when parked on an inclined surface? If you are unsure, find a steep hill and park your car for about 30 minutes. This will help you get the answer.

If this is the reason for leakage, then the fault is likely to be within the sunroof.

When AC is Running:

Your AC should not release unwanted moisture. To test it out, you will have to sacrifice comfort and sit in the heat for some time. Go for a drive without your AC running. Monitor all the places where water gets accumulated. If you see some changes, you are a step closer to fixing them.

This can happen due to faults in parts like the air conditioning system or heater core. If you have been experiencing this issue, look for a car water leak specialist near me to fix it.

How to Fix Water Leaking into Car?

No matter what the reason is, it is important to fix the water leaking problem in your car. Here are some parts that need to be fixed to stop water leaking problems.

Roof Seams:

Water leakage can occur due to a damaged roof. You need to test on the seams all around the roof. If you notice any cracks in the paint or bubbling, this is where the leak is. Another way to locate the leak is by finding any rust on the body.

If it’s rusty, sand it and clean it with rubbing alcohol. You can also apply some touch-up paint to fix it. You might need the help of professionals if the damage is too extensive. They will get rid of the damaged part.

After the rust has been taken care of, you will see a rubber gasket which is required to seal the space. However, it is more likely to wear out when compared to metal. Apply a sealant over them to avoid replacing the rubber.

Sunroof Drain:

The sunroof owners have to face the worst disadvantages during the rainy season. When there are issues with the rubber gasket, professionals use sealant to fix it.

In case your sunroof doesn’t close properly, clean it thoroughly. Often dust and dirt accumulate inside the sunroof that can cause difficulty in closing it thoroughly.

Another way to fix it can be a bit tricky but you can still do it on your own. Your sunroofs have a draining system that keeps the rainwater away from entering your car. If your vehicle has an air compressor, blow the dirt out of the drainage system. This will help you get rid of any clogs.

Windshield Gasket:

If the problem is the windshield gasket, get rid of the rust by sanding it. Clean it and apply some touch-up paint. If the problem is a bit bigger, seek help from a mechanic.

To fix a smaller problem, you can use silicone, butyl or maybe urethane sealants to secure it. This will help you get rid of the windshield leaks.
