Why is My Car leaking water?

car leaking waterWith all the fluids your vehicle holds, it’s actually surprising that you don’t find things leaking more often that you do.  Your vehicle holds various types and amounts of fluids from engine oil to windshield washer fluid.  Based on the type and use of these fluids it’s surprising that your vehicle doesn’t leak more things more often.  If you’re asking why your car is leaking water, then you’ve most likely got a leak in one of two places.  We say “most likely” because there are odd times where it will appear that your car is leaking water when it actually isn’t.  The two most common occasions are if your air conditioning condensate water and your cowl drains.  Both of these drains exit your car in or close to the rear of your engine bay and aren’t actually leaks, but simply drains directing water away from the cabin of your vehicle.  Your AC condensate drain will drip water when your AC has been running and it’s a warm humid day.  Your cowl drains will drip water after you have used your windshield washers or if your windshield gets wet otherwise.

To help figure out why your car is leaking water, it’s important to understand the 2 systems in your vehicle that use water-based fluids.  Those two systems are your windshield washing system and your engine cooling system.  Your windshield washing system is made up of a reservoir where the washing fluid is stored, a pump, hoses to carry the fluid and the nozzles that spray the fluid onto the windshields.

Unless you’re using the windshield washer system, there is no fluid flow or pressuring in the system so it is very unlikely you would have a leak.  The most common leaks in your windshield washer system is a crack in your fluid reservoir due to frozen washer fluid expanding and causing cracks.  The best way to avoid this is to use windshield washer fluid that has a low freezing point.  If you’ve already got a cracked reservoir, the best way to solve the issue is to simply install a new reservoir in your vehicle.

The other system that uses a water-based fluid is your engine’s cooling system.  If your car is leaking water, then this system is most likely the culprit.  Your cooling system is the most common leak source because it is a pressurized system.  The high pressure can force coolant out even the smallest of leaks.  Along with the high pressure, your cooling system is comprised of relatively fragile heat exchangers, hoses that can deteriorate or tear and other gaskets that can start to leak over time due to heating and cooling cycles.

If you find your car leaking water, it’s important to find the source of the leak to keep your car safe.  If your cooling system gets low on water it can cause overheating which can lead to permanent damage.  Often times it can be difficult to track down the source of water leaks in your car due to the amount of hoses and possible leak locations.  One of the easiest ways to seal a leak and keep your car running properly is to use BlueDevil Radiator and Block Sealer.  BlueDevil Radiator and Block Sealer can be easily added to your vehicle’s coolant and it will seal a leak in your radiator or engine block stopping the leak and keeping your car running safely.
