Antifreeze Leaking Under Car Passenger Side Why and How to Fix

Antifreeze is commonly used in cars as a coolant to help protect against the effects of heat. However, it is not uncommon for antifreeze to leak under the passenger side of a vehicle.

Antifreeze can leak from anywhere on the car or truck, but typically it will leak from the radiator, where it is located on top of the engine block. The problem with this type of leakage is that it can damage other parts and components in your car or truck if you do not fix it right away.

 

Why Antifreeze is Leaking Under Car Passenger Side

 

Antifreeze can leak from several places on your car, including the radiator, air intake, or power steering lines. If you notice antifreeze dripping onto your driveway or garage floor, it’s time to call a professional auto repair shop to fix it for you before it causes any damage.

The 5 Reasons Why Antifreeze is Leaking Under Car passengers Side are:

  1. Air intake: if antifreeze gets into the air intake of your car due to clogged filters or an obstruction in the tubing, it can leak onto the ground when you drive.
  2. Radiator: the antifreeze can leak into your radiator and cause a coolant leak after you’ve driven for a period of time.
  3. Power steering lines: power steering hoses often have leaks near the reservoir that antifreeze has to pass through, so if they’re damaged, they can get into the power steering system and leak.
  4. Engine oil: antifreeze can leak into your engine and cause a coolant leak if you’ve accidentally driven with the wrong type of oil in your car.
  5. Power steering fluid: pressure build-up in the system may cause antifreeze to leak through a vacuum hose near the reservoir.

 

How to Fix Antifreeze Leaking Under Car Passenger Side

 

Antifreeze leaking under car is a very common problem. It happens when the antifreeze leaks out of the radiator and onto the ground. To fix this, you have to change a few things in your car.

Some of these things include:

  • Flush the radiator with water by opening the cap on top of the radiator and pouring water in it.
  • Remove any hoses that are clogged.
  • Replace any old gaskets.
  • Check for leaks around hose fittings and tighten them if needed.
  • Replace any cracked or damaged hoses.

 

How to Find a Coolant Leak Without a Pressure Tester

 

Pressure testers are important tools that help you locate a coolant leak. However, they are not always available when you need them. The following steps will guide you on how to find a coolant leak without a pressure tester:

  1. Check the radiator for leaks.
  2. Use your hand to feel for any signs of heat in the engine compartment, such as an oil or coolant smell, steam rising from the engine, or heat radiating from the engine compartment.
  3. If you can’t find any signs of heat in the engine compartment and there is no oil or coolant smell, use water to check for leaks.
  4. In some cases, it may be difficult to tell if water is leaking from the radiator because the coolant looks like water. If this is the case, take an old towel or a piece of cloth and soak it in the coolant.
  5. Place your soaked cloth over a low-pressure vacuum source (like a vacuum cleaner hose), then place the other end into one of the radiator’s openings.
  6. Watch for bubbles to appear, which will indicate a leak.

Coolant leak detection is an important part of automotive repair. In order to find the leak in the system, you need to use a pressure tester. However, if you do not have one, there are other ways to detect it.

If there is no pressure tester available, you can use a variety of tools to find the leak in your cooling system. You can also use a temperature gauge and a thermometer as they provide more accurate readings than a regular thermometer.

 

Signs of car leaking antifreeze when parked

 

Anything ranging from a head gasket that is blown, a broken cylinder head, or even an exhaust manifold leak could cause your car antifreeze to be leaking off your car. So you should inspect your car for the following signs and symptoms before taking it to the mechanic.

Here are some signs and indicators that your car leaking antifreeze when parked or Coolant when driving. If you noticed you are losing coolant or antifreeze, there could be many things to it.

  • A gasket failure.
  • A loose hose connection.
  • A bad head gasket.
  • A cracked cylinder head.
  • The cooling system is damaged or clogged with debris.
  • The radiator cap has been left off for too long.

If you ever notice any of the above-mentioned signs and symptoms in your car, then you could be losing car coolant. It is important that you should take quick action when you notice your car leaking antifreeze when parked or driving.

Can you lose coolant without a leak?

 

Yes, if you lose coolant without a leak then it means you might be having a blown gasket or loosely tight radiator cover. If your car leaking antifreeze or coolant and you can seem to locate it, then it must be leaking into the combustion chamber through the broken head gasket.

Leaking your car coolant into the combustion chamber will leave no visible on the ground or anywhere you can see. The only way you can notice it is by taking a look at the exhaust.

The most evident sign of a blown head gasket is an unusual white smoke coming out from the exhaust. This is because unlike gas, which leaves mostly clear or black exhaust fumes, coolant burns white.

 

 

Another way by which your car can lose coolant without a visible leak is through the radiator cap just like I have mentioned before. If the radiator cap is not holding and covering the pressing in the system as expected, some amount of antifreeze will be lost through steam.

To be sure that the radiator is kept intact, start your car and allow the engine to warm up for a few minutes. After a few minutes of running the car, off the ignition and open the radiator cap to have a very good look for any form of steam.

Normally there should be no form of steam or smoke coming from the cap, and if you do, then you’ll need to replace it. If you have done all the steps above then by now you should found out how your car is leaking antifreeze when parked.

 

 

What are the signs of a blown head gasket?

 

The head gasket in your car is designed to seal the cylinder’s firing pressure and keep it inside the engine. The car’s head gasket also prevents coolant and engine oil from leaking into the cylinders as well as to the outside.

The head gasket must withstand the stresses of the two surfaces expanding, shrinking, warping, and rubbing while sealing in-cylinder pressure, coolant, and engine oil running through casting ports. Here are signs to look for to know if you have a blown gasket or not.

  1. Unusual white smoke from the exhaust.
  2. Bubbles from the tip of the radiator cover.
  3. Bubbles from the antifreeze or coolant container.
  4. Unexplainable antifreeze loss with no visible leaks.
  5. Milky white coloration in the oil.
  6. Overall car engine overheating.
  7. Check for unusual engine smoke.

 

What do you do if your car is leaking antifreeze?

 

If you ever notice that your car is leaking antifreeze or coolant, it is not a good sign but it is not too bad just yet. What you should do the moment you start noticing a leak of coolant or antifreeze is to consult a professional mechanic immediately.

Leaking of antifreeze could just be a secondary problem while the primary problem could cause other severe damage if not checked in time. In other to help keep your car in good working condition you need to keep close attention and eye on your coolant level and check for overheating.

 

Why is my car leaking antifreeze but not overheating?

 

This could be because the leak has just started and you were able to notice it in time. If your car is leaking antifreeze but not overheating or you have a car leaking antifreeze when parked, you still have a chance to repair your vehicle for a lower cost.

Other reasons why your car is leaking antifreeze but not overheating could be due to the radiator losing the cap. Chances are you have either a radiator cap leak, internal coolant leak, or an external coolant leak.

 

Conclusion

 

Antifreeze can leak from the car if it gets wet or if it’s punctured by something like a nail. The liquid will mix with water and corrode metal parts like the battery cables, fuel lines, and catalytic converters. It can also cause severe burns to people who come in contact with it.

If you notice antifreeze leaking under your car, you should make sure to remove any objects that may have caused the leak and take your car in for service as soon as possible so they can repair any damage done by the leak.
