Choose Your Coolant Leaks Help Topic Below
Finding and fixing coolant leaks; as soon as possible is crucial to the health of your engine. Consequently, Coolant leaks can occur anywhere in the cooling system; but the good news is they are usually easy to find. Mostly, because coolant leaks can be seen dripping, spraying, seeping or bubbling from the leaky component.
So, The engine’s cooling system works by circulating a coolant and water mixture; under pressure through the engines cooling system.
Consequently, The temperature of the coolant rises as the engine runs and the coolant expands. So, any excess coolant in the system moves into a reservoir tank by way of rubber hoses. But, when this system isn’t working properly; you risk running into expensive repairs. Thats why, Fixing a coolant leak as soon as possible is crucial. Consequently, The first symptom of trouble is usually engine overheating.
So, If you suspect your vehicle has a coolant leak; open the hood and visually inspect the engine. Next, Check the cooling system for any sign of liquid leaking from the engine; radiator or hoses. You may also notice a sweet smell, which is a characteristic odor of ethylene glycol antifreeze. Most cooling systems today are designed to operate at 8 to 14 psi. So, If the radiator can’t hold pressure; your engine will overheat and lose coolant.
External Coolant Leaks
An external leak is the type of leak which is most easily diagnosed. More often than not; when you have an external leak, the coolant escapes and your car quickly overheats. Most likely you can easily spot where the leak is coming from by looking at it; a split or broken hose or a hole in the radiator are two good examples. Leaks in the water pump; heater core; or engine freeze plugs can also allow coolant to escape. These too are easy to diagnose by a visual inspection.
The Most Common Locations For External Coolant Leaks Include:
- Freeze Plugs
- Heater Core
- Intake Manifold Gasket
- Leaky Radiator Cap
There are the worst kind of coolant leaks for two reasons:
- One is that they are impossible to see because they are hidden inside the engine.
- The other is that internal coolant leaks can be very expensive to repair.
So, An internal leak won’t cause a puddle of coolant under your car. But, it will be noticeable when your coolant level does not stay constant. Also, you may find that you need to constantly refill the coolant tank; to keep your engine from overheating. An internal leak could be caused by a leak in the head or block; or perhaps a leaky head gasket.
The Most Common Locations For Internal Coolant Leaks Include:
- Bad Blown Head Gasket
- Cracked Head Or Block
- Leaky ATF Oil Cooler
You may also find that you have a crack in the coolant reservoir. Since the coolant in the main system is what is keeping the engine cooled; the engine should not overheat. But, you will see coolant pooling under your car when it sits for long stretches of time.
