Q: Heater core problems? Discover 5 common causes & solutions.
A:
Heater core problems can lead to insufficient heating inside your car, which can be very uncomfortable in extreme cold weather. Here are 5 common causes and solutions for heater core problems.
1. Dirty or clogged heater core.
The heater core can get clogged with dirt, debris, or coolant residue, reducing the flow of hot coolant through it and resulting in poor heating. This can be solved by flushing the heater core using a radiator flush solution.
2. Leaking heater core.
A leaking heater core can cause coolant to leak inside the car, leading to a sweet odor and sometimes foggy windows. This is a serious issue that can cause damage to the interior of the car. The best solution for this is to replace the heater core.
3. Faulty thermostat.
The thermostat regulates the flow of coolant into the engine and the heater core. If it's faulty, it can cause insufficient heating or no heating at all. Replacing the thermostat can solve this issue.
4. Low coolant level.
Low coolant level can cause insufficient heating since there's less hot coolant circulating through the heater core. This can be solved by adding more coolant to the system.
5. Broken or malfunctioning heater fan.
The heater fan blows hot air from the heater core into the car's cabin. If it's broken or malfunctioning, it can cause little or no heat inside the car. Replacing the heater fan can solve this issue.
In summary, heater core problems can be caused by a dirty or clogged heater core, leaking heater core, faulty thermostat, low coolant level, or broken/malfunctioning heater fan. Addressing these issues can ensure efficient heating inside your car during cold weather.
