Corroded Heater Core
Causes of Corrosion in Heater Core
A car’s heater core is often one of those parts that people don’t think about until there’s a problem. One common issue with heater cores is corrosion, which can cause leaks and an overall decrease in the effectiveness of the heating system. But what causes this corrosion?
One factor is the type of coolant used in your car’s engine. Over time, coolant can become acidic due to reactions with air that create compounds like nitric oxide. This acidity can eat away at the metal in the heater core and other parts of the cooling system, leading to rust and eventually holes.
Another potential cause of corrosion is simply age. Most cars have their original heater cores installed from the factory, meaning they could be decades old. As metal ages, it becomes more susceptible to damage and wear, including corrosion.
Finally, poor maintenance of the cooling system can also contribute to corrosion in the heater core. Neglecting routine flushes and changing the coolant as recommended by the manufacturer can allow contaminants to build up in the system and corrode the metal inside the heater core.
Signs of a Corroded Heater Core
So how do you know if your car’s heater core has suffered from corrosion? There are a few signs to look out for:
- A sweet smell coming from the vents when the heat is on (this indicates coolant leaking into the cabin)
- Fog or mist on the inside of the windshield despite using defrost settings
- Coolant stains or puddles under the dashboard or near the front of the vehicle
- The interior of the car feels damp or humid even when it’s dry outside
- A hissing sound coming from the dashboard or engine bay (this could indicate a leak in the system)
If you notice any of these signs, it’s important to have your car inspected by a licensed mechanic as soon as possible. A corroded heater core can lead to serious problems if left unaddressed.
“If your vehicle has lost heating power or is putting out anything less than hot air through the vents, it’s pretty likely that your furnace core needs replacing,” says Tim Esterdahl of AxleAddict.com.
If neglected, a damaged heater core can cause your car’s cooling system to fail entirely, leading to costly repairs and potential damage to your engine. Not to mention, a car without heat in the winter months can be unsafe and unpleasant to drive.
Corrosion in a car’s heater core can be caused by acidic coolant, aging parts, and poor maintenance practices. Signs of a corroded heater core include sweet smells, fogged windshields, and coolant stains or puddles. It’s vital to get your car checked out by a mechanic if you suspect there’s an issue with the heater core, as ignoring the problem can result in significant damage to your vehicle.
Leaking Head Gasket
Discovering water under your car can be alarming. While a puddle of water or condensation from the air conditioner is normal, continued leakage may indicate something more serious. One possible cause of water leakage is a leaking head gasket.
What Causes a Leaking Head Gasket
The head gasket plays a critical role in sealing the combustion chamber and keeping fluids separate. It sits between the engine block and cylinder head to prevent coolant and oil leaks into combustion chambers while maintaining proper compression. However, frequent overheating caused by various reasons can damage the head gasket and lead to leaks.
According to experts at Car From Japan, “When an engine gets too hot, metal components are more prone to warp and expand beyond their limits. The metal on the head gasket can also warp, leading to cracks, which further allow gasses and liquids to leak through.”
An old worn-out head gasket can also cause issues as weakened areas are more susceptible to tears and cracks that could lead to fluid leaks.
Signs of a Leaking Head Gasket
To know if your car has a leaking head gasket, here are some common signs you need to look out for:
- White smoke: White steamy exhaust smoke could mean the presence of antifreeze mixing with oil.
- Overheating:A constant increase in temperature even when driving over short distances is a sign of a leaking head gasket. Additionally, a pooling of coolant outside the vehicle during parking could mean there’s a problem with the head gasket.
- Milky oil: A milky white substance found on an oil dipstick could be a result of coolant mixing with engine oil, which is caused by head gasket failure.
- Unusual fluid levels:If you notice that the engine coolant and oil levels are dropping quickly but regularly topped off, then there’s likely to be a leaking head gasket. In addition, if there appears to be bubbles in the coolant tank during cold start-up or while driving, this is another sign of possible head gasket problems.
The above warning signs should prompt you to seek professional help immediately to avoid further damage to your car’s vital components. “Ignoring these signs can cause significant damage to other parts of your vehicle and risk turning your auto into a time bomb.” warns Dan Ferrell from LiveAbout.
“Don’t ignore any indication of cooling system problems since ignoring them long enough is guaranteed to lead to severe engine damage” Paul Weissler from Popular Mechanics advises.
Reacting promptly to early symptoms of a bad head gasket will save expensive repairs in the future.
