The North wind doth blow, and there will be snow, but your car heater is blowing cold air. Instead of freezing, bring your car to the experts at Havoline® Xpress Lube of Kernersville.
Common Reasons Why Your Car Heater Is Blowing Cold Air
It may seem like a broken car heater isn’t a big deal. So, you’re a little cold when you go out for a drive. However, your car’s heating system is part of the cooling system that keeps your engine cool. Any problems could result in an overheating engine.
Accordingly, when experiencing problems with your car heater, you need to check the following components:
1. Low/Old Coolant
The right amount of coolant is necessary for your car engine to operate at optimal efficiency. Yet, coolant leaks can occur in many different places. For example, radiators, hoses, gaskets, or water pumps are common areas for losing coolant. In addition to coolant levels dropping, leaks allow air to enter the system. However, compared to coolant, air is a poor medium for absorbing and releasing heat. Thus, your heating system will blow cold air.
Moreover, coolant loses its effectiveness as it ages. Delays in flushing the system can also affect your car’s heat.
Typically, coolant runs between $10-$15 for a gallon jug. However, fixing a leak averages about $275 with some repairs costing over $1000.
2. Broken Thermostat
The thermostat is a valve that helps the engine reach optimal operating temperature quickly, and keep it there. It stays closed when the engine is cold to bypass the radiator so the coolant warms quickly. Once the engine is hot, it opens allowing coolant to flow to the radiator to release heat.
When a thermostat fails, it can get stuck in either the open or closed position. Generally, if it’s lodged in the closed position, your engine will overheat. While an open position will result in cold air blowing from your vents. Usually, the average cost for car thermostat replacement is between $661 to $747.
3. Air In The System
Typically, the heater core sits at the highest point of the cooling system. Air bubbles can enter and become trapped by a bad radiator cap, flush, or leak. Once inside, air can prevent coolant from flowing. Often, you’ll know you have air by a gurgling sound from behind your glove box.
To remove trapped air, you need to burp the system. The average price to remove air from the cooling system is about $70-$150
4. Electrical Issues
Usually, if you have an electrical issue, you won’t feel any air blowing through your vents at all. Electrical issues can range from a blown fuse to a failing fan motor. While the cost of replacing a blown fuse is only about $100, replacing a fan is about $350.
5. Heater Core
The heater core is a small radiator located on the passenger side inside the cabin. Just like the radiator, this part is susceptible to corrosion. Moreover, failing to routinely change your coolant can speed up the process through electrolysis. Replacing it is an expensive job, ranging from $800-$1000.
Some Signs You Have A Failing Heater Core
Usually, the heater core will last about 5-7 years or 50,000-70,000 miles, although some will last much longer. As it fails, you may notice one or more of the following signs:
- Fog in the cabin
- Sweet musty smell
- Consistently low levels of coolant
- Cold instead of warm air blowing from vents
One of the ways to extend the life of this part and the heating system is to perform routine maintenance. In this case, that means flushing the coolant every 30,000- 100,000 miles, or 2-5 years. Furthermore, always use a quality antifreeze.
