As soon as I start the car it starts to leak coolant on the driver sidereal under the car it leaks fast and before the car get a chance to warm up
My car has 244000 miles.
My car has an automatic transmission.
Expert automotive mechanics share their insights :
Many coolant leaks will leak more profusely when the engine is running due to the amount of pressure that is built up as a result of the water pump circulating the coolant through the engine and the intense heat generated by the engine running. When the engine is not running, the pressure does not exist, thus reducing the chance for the coolant to leak in the event that a leak exists in the system. I would recommend having an expert from this site come to your location to diagnose and repair your coolant leak.

The leak that you are seeing could be from a coolant hose that is either loose or split. Also the coolant leak could be coming from a core plug (freeze plug). The best way to track a leak is to put coolant dye into the radiator, drive the vehicle for a couple of miles, and then pressure test the system.
A coolant/antifreeze leak can occur for a variety of reasons, including a blown radiator hose, a bad hose clamp, warped head gasket, or the most common reason, a foreign object kicked up by the truck in front of you penetrating the radiator itself.
Warm coolant from your engine is pumped through the heater core, then your cabin ventilation system uses that to heat the air in the cabin of your vehicle. If the heater core is leaking you will find coolant on the floorboards of your vehicle, most likely on the passenger side.
One common place of a coolant leak is the radiator pan gasket. The drain plug can also cause leaking, and if the cap that seals the radiator can no longer contain the pressurized coolant, it will leak or spray out from underneath.
Coolant leak from the top of your car`s radiator can be caused by several reasons- loose or damaged radiator cap being the major one. It can also be caused by fractured or leaking coolant hoses. It has also been found that a clogged radiator may also leak.
Chances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. The longer you wait the higher the coolant leak repair cost will be. Learn how to diagnose your antifreeze leak and learn what to do next.
Engine Overheating
A failed head gasket means the engine will have to work harder to create power. Furthermore, a blown head gasket can cause your vehicle to lose coolant, causing the engine cooling system to underperform, making the overheating situation even worse.
Look for signs of coolant leakage—a light-colored residue or stain—around the radiator cap, on hoses throughout the engine compartment (check the ends where they are clamped to other components) and on the radiator itself. If it looks like a hose is leaking near a clamp, try tightening the clamp with a screwdriver.
It is often associated with a bad head gasket that is allowing coolant to seep into the engine`s combustion chamber. If your coolant level is low despite no visible leaks under the vehicle, then it might be a problem with the head gasket that you`ll want to have inspected and repaired.
This is where the real dangers of overfilling your coolant lie. Hot coolant leaking throughout your engine bay can cause serious damage to wiring and electrical components. If you do end up with a burst hose, your engine could be starved of coolant and cause some pretty big problems.
The first thing you need to do is locate the source of the coolant leak. It might not be coming from the radiator. The best way to confirm the source of the leak is to wash the radiator and hoses with water, and then start the engine and look for new signs of coolant.
How much coolant loss is normal? Providing that the engine is running well, with no leakages or damage, you can expect a coolant loss of 0.25% every four to six months. This means a loss of two to three ounces a year is completely normal.
Antifreeze (aka coolant) is pumped through your vehicle`s engine as you drive, absorbing excess heat and exchanging it with the outside air. That means an antifreeze leak could cause the engine to overheat — and that can lead to major engine damage.
Water by itself can`t do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle`s engine. Plus, it doesn`t absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
The best thing to do is avoid driving long distances with a coolant leak as this can cause further damage to the engine. The last thing you want is to have a more expensive trip to the mechanic. If you experience an overheating engine due to coolant leaks, get a mechanic to look at it as soon as you can!
The Steel Seal Blown Head Gasket Fix Repair Sealer is our top pick for the best overall permanent head gasket sealer. It works well on older and new vehicles and is suitable for cars, vans, SUVs, and trucks. If your budget is a little tight and you still need a professional-grade sealer, check out the K-Seal ST5516 HD.
When intake manifold gaskets become damaged, coolant may begin escaping from its system. Eventually even a relatively small leak will eventually cause coolant levels to drop to dangerous levels. Be sure to take note of any signs that your car may be experiencing a coolant leak.
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
When a water pump completely fails, it is no longer able to move coolant through the engine; this causes it to overheat. If you see steam, pull over immediately and call your mechanic for assistance — continuing to drive with an overheated engine can damage it to the point that it will need to be completely replaced.
Common problems include overheating, leakage, low water pressure, noisy operation, and cavitation. These problems can be prevented or fixed by regular maintenance, inspection, and replacement of worn-out parts.
To check if your pump is operating efficiently, measure the power consumed by the pump and check it against the pumps performance curve. The pump curve will specify how much power you should be using at the flow and pressure your pump is generating. This helps you to identify which pumps are not operating efficiently.
Synonyms for Coolant Leak
If coolant leaks, it`s the antifreeze you`ll notice because of its bright color. Radiator leak: A coolant leak may involve a leaky radiator, but the culprit could also be another part.
The real danger of overfilling your coolant lies in the possibility of hot coolant leaking throughout your engine bay, which could cause serious damage to wiring and electrical components. If a hose does burst, your engine could be deprived of coolant and cause significant issues.
