What makes a heater core go bad?
How does a heater core go bad? There are multiple reasons a car's heater core could not be working properly. One reason could be due to clogging, as the coolant could become contaminated if it's not regularly flushed out. Another reason for a bad heater core could be because of a leak somewhere in the system.
Can you drive a car with a bad heater core?
If you have a bad heater core, you should bring your car in for repairs right away. Driving with a faulty heater core can be risky, as it can lead to overheating and extensive engine damage. Even a clogged heater core can prevent proper coolant circulation, causing your engine to run hot.
How long does a heater core last?
No automotive component lasts forever, though, and heater cores are no exception. It's not uncommon for heater cores to fail after about 10 to 15 years; with a neglected coolant system, failure can occur even sooner.
How much is a heater core replacement?
Replacing the heater core can be an expensive job, and usually costs between $564 – $927 for parts and labor. The parts aren't particularly expensive, normally costing $80 – $234, but the location of the heater core means that labor costs tend to be quite high.
Can a clogged heater core cause an engine to overheat?
While your vehicle's heating system needs coolant to warm the interior, the engine needs coolant to keep it from overheating. If there is a clogged heater core, it will keep the coolant from flowing through the engine, causing it to overheat.
How much does it cost to unclog a heater core?
In general, a heater core flush typically costs somewhere in the neighborhood of $75-$100.
Can you fix a heater core without replacing it?
Fixing a leaking heater core will always be much easier than replacing one. Since it is only a small leak in the heater core, we recommend simply sealing that leak and leaving your heater core in place. You can do this by simply by adding BlueDevil Pour-N-Go to your vehicle's radiator when your vehicle is cold.
Will a bad heater core cause AC to not work?
The heater core will not cause the A/C to not blow cold. If your A/C is working properly with the correct amount of refrigerant, then you may have a temperature blend door not working and staying on heat mode.
Why is car blowing cold air from the heater?
Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car.
How long does a heater core last in a vehicle?
A: Most heater cores are designed to have very long use-lifes, averaging about 10-15 years. Obviously, if you put strain on your heater core or fail to remedy a fault when it occurs, such as the heat not working as well as it once did, that life will be considerably shortened.
How long will aluminum heater core last?
HEATER CORE FAILURES: The approximate life span of a OEM copper/brass heater core is 5 years or 50,000 miles, while the approximate life span of an OEM aluminum heater core is 7 years or 70,000 miles.
Why does my car heater not work?
A heater can stop working for a number of reasons, including: A low antifreeze/water level in the radiator due to a leak in the cooling system. A bad thermostat that isn't allowing the engine to properly warm up. A blower fan that isn't working properly.
How do you know if your heater control valve is bad?
Common signs include the heater not working, coolant leaking from under the engine, and no voltage across the heater control valve.
