Are you notice green fluid leaking from car and want to find out what it is, why it is happening, and how to fix it? Worry no more because we have the answers you need.
This article provides you with the common you have green fluid leaking from car, what it is and how to fix this problem.
Let’s get started!
What Is the Green Fluid Leaking From Car?
If you notice green fluid leaking from a car, it is most likely antifreeze. Antifreeze leaks out of the vehicle’s water pump, radiator, and hoses, when fittings, clamps, hoses, and other units get damaged or when these components haven’t been connected properly.
Check the owner’s manual to know which antifreeze is suitable for use. Using an antifreeze that is not fit for your car can cause leaks.
What Is Coolant/Antifreeze?
A Car engine requires essential fluids like antifreeze, often called coolant, to keep its temperature in check.
With the help of the coolant, the engine can still operate at normal temperature during cold or hot periods.
Antifreeze is made from ethylene glycol and silica. It is combined with water to form coolant.

Why Is Green Fluid Leaking From Car
Below are reasons why you have green fluid leaking from your car
1. Hole in the Radiator
One of the major reasons you have the green fluid leaking from car problem, which is a coolant leak, is a hole in the radiator caused by corrosion.
Old tubes that are weak can have debris and sediment in them, which may cause a leak. Also, the gasket sealing the space between the tank and your radiator can wear out over time leading to coolant leaks.
The clamps and hoses attached to the engine radiator can also be an issue if used for a long time.
Older hoses won’t seal well since they are hard and weak, making the areas that connect them to the water pump, heater, and radiator exposed to leaks.
2. Leaky Radiator Cap
A radiator cap may seem small, but it plays an essential role in cooling systems.
Since your radiator is greatly pressurized, the cap does the job of formulating a tight seal to keep the cooling system in check, especially at the proper pressure.
As time passes, its seal gets weak, or the spring starts wearing out, causing coolant to leak out of the radiator.
3. Blown Head Gasket
A good head gasket plays an important role in how well your car engine functions. When your head gasket blows, you may not notice it for some time.
Your car could run for some time before noticing an issue. Remember, just like other engine parts, the gasket must withstand extreme temperatures and pressure encountered in your engine.
It is fixed between the engine system and the cylinder head, and when a leak develops, you can say that it is “blown.”
If this is the case, your gasket won’t be able to keep the coolant and the engine oil separate. This is very risky and could lead to your engine shutting down.
Also, coolant gets to ooze out of the engine system, and as your coolant level drops, your car finds it difficult to cool down.
4. Damaged Water Pump
Water pumps are responsible for the circulation of coolant around the cooling system. Water pumps are located near the drive belts on the lower side of the engine block.
Water pumps are connected to radiator lower hoses, but the connection may become loose or wear out. It could also be damaged by external factors, causing it to leak.
If the water pump develops issues that hinder it from functioning, the engine is prone to overheating.
5. Problem With the Expansion Tank
Cars are equipped with an expansion tank (a plastic container at the side of the engine) which helps supply coolant to the radiator.
A rubber hose connects the expansion tank to the radiator, with which the tank donates and accepts coolant throughout the radiator as the engine system cools down or heats up.
After some time and much vulnerability to temperature changes, the tank becomes weak, and so do the parts that connect to it.
The container can get cracked, or the lid leaks, causing the coolant to escape. Possibly, it could be a loose connection resulting from deteriorated hoses that allow fluid to leak.

How to Fix Green Fluid Leaking From Car (How to Fix Coolant Leak)
A lot of factors cause antifreeze leaks. A lot of things can be done to fix it.
Replacing the faulty part entirely is considered the best option, but there are still some procedures you can try. Below are a few:
1. Replace Clamps
Clamps are used to hold the hoses together. Any of them affected by corrosion or rust has to be replaced.
Let your car cool down. Detect the faulty clamp. If replacing it requires that you empty the coolant into a container to get hold of the faulty clamp, then do so.
Remove the bad hose and the worn clamp too. Replace it with the new one and put them back together.
Refill the radiator and tighten the cap. Drive until your car gets to the normal working temperature. Check the engine for any more leaks.
2. Replace Hoses
Replacing a defective hose follows the same procedure as when replacing a clamp. You can switch the clamp as you take off the hose.
Let the car cool down. Detect the faulty hose. If it requires that you empty the coolant into a container for you to get hold of the faulty hose, then do so.
Remove the clamps that connect the hose. Change the affected hose with a new one and put the clamp back.
Refill the radiator with fresh coolant and test the engine for any more leaks.
3. Change Radiator
Car manufacturers have different styles of installing a radiator. However, the steps for every replacement are similar.
First, your car needs to cool down. After which, you detach the car battery. Pull out the plug from the radiator’s lower part and drain the coolant from the cooling system. Ensure this coolant is disposed of properly.
Take off any hoses connecting the radiator to the engine and remove the thermostat. If you see a fan fixed to the radiator, take it off too. The bolts connecting the radiator to its position should be taken out.
The worn radiator should be removed and replaced with a brand new one. Then re-assemble the components replacing any parts that have to be changed as you do so.
Refill the radiator with fresh coolant and turn on the engine to see if there are any more leaks.

4. Use Eggs
What comes to mind when you are stuck on a lonely road with a leaking radiator?
Eggs could help if there are any in your car; at least it would buy you some time. But, this method is not strongly recommended if you have other options you could work with.
Let your car cool down, then loosen the radiator lid. Get some eggs, crack them up and let them settle in the reservoir. But, If the coolant leak persists, try again with more eggs.
In the process of cooking, fluid pressure will try to force the eggs through the holes to escape.
If everything goes correctly, the eggs get stuck in the hole and close the Leak for some time. Using eggs to fix coolant leaks can lead to more damage, which is why most mechanics won’t suggest it.
Besides using eggs, there are other additives you can use to fix coolant leaks. However, according to some reports, using these additives can clog your cooling systems, so you need to be extremely careful.

Coolant Leak Repair Cost
Coolant leak repair costs between $10 to $3000. A brand new hose or clamp is not expensive compared to a radiator replacement, which costs about $300 to $1,200, particularly for labor and parts, while gasket replacement costs $2,000 or even more.
Repairing a leak immediately after getting a warning signal before it gets out of hand is far the easiest way to reduce expenses.
Frequently Asked Questions – Green Fluid Leaking From Car
What Green Fluid Is Leaking From My Car?
Green fluid leaking from your car is likely an antifreeze. One of the major leaks associated with automobiles is antifreeze leaks. Usually, these leaks result from clamps or hoses that are worn out or not connected well.
Can I Drive My Car if It’s Leaking Green Fluid?
When a green or greenish-blue liquid leaks from your car, it is likely a coolant or antifreeze. If coolant is leaking from your car, please avoid driving. If you drive your car with a coolant leak, the engine will overheat, leading to further damage.
Is Transmission Fluid Green?
Transmission fluid comes in so many colors nowadays. It can appear yellow, green, or blue- though it is not common. But, the most likely transmission fluid color is bright translucent pinkish red, so if you see this, it’s normal.
