Why is the heater in the Changan Yuexiang not heating up?

[Brantley]

The reason why the heater in the Changan Yuexiang is not heating up is: the heater core is clogged. Taking the 2019 Changan Yuexiang as an example, its body structure is a 4-door, 5-seater sedan with body dimensions of: length 4390mm, width 1725mm, height 1490mm, wheelbase of 2535mm, fuel tank capacity of 40 liters, and a curb weight of 1050kg. The 2019 Changan Yuexiang features a front MacPherson independent suspension and a rear torsion beam non-independent suspension. It is equipped with a 1.4L naturally aspirated engine, delivering a maximum horsepower of 101ps, maximum power of 74kw, and maximum torque of 135nm.

When driving my Changan Alsvin, I noticed the heater isn't producing warm air, which is really frustrating. Possible causes include insufficient coolant, which is the most common issue, preventing the heating system from properly warming the air. I checked the cabin air filter; if it's clogged with dust, the airflow from the heater can become weaker or cooler. There might also be a problem with the control system, such as a faulty temperature sensor that can't regulate the outlet air temperature. If the heater core is blocked, the engine's heat can't transfer through, making winter drives uncomfortably cold. A malfunctioning fan or blower could also be the culprit, as reduced airflow means less warm air. I think it's best to first try setting the temperature to the highest and turning the fan to maximum. If that doesn't work, it's time to visit the 4S shop for a check-up to avoid freezing in winter. Regular maintenance, including coolant replacement and filter cleaning, can prevent these issues.

Last time when I drove the Yuexiang, the heater wasn't warm. I remembered it was because the water pump was broken, and the coolant wasn't circulating, so the heat couldn't be transferred. In my experience, I've also encountered situations where the heater core was leaking or clogged, and the heating effect would disappear immediately. Minor issues like a dirty air filter can also cause this problem, and regular cleaning can solve it. When checking, you can see if the water temperature gauge is normal. If the engine temperature is low, the heater will naturally not be warm. If you hear abnormal noises from the blower, the fan might be stuck. Don't ignore it; failing to repair it in time might affect visibility in foggy weather and increase the risk of accidents. I once solved the problem by simply replacing the filter myself, which was not costly. Overall, heater problems are often related to coolant and filters, and preventive measures can save a lot of trouble.

If the heater isn't warm, check these simple things first to save money. I've tried checking the coolant level - if it's too low, just top it up. Inspect the fuse box and replace any blown fuses related to the system. If the cabin air filter is dirty, remove it for cleaning or replacement. Turn the fan to maximum speed - if there's no sound, the blower motor might be faulty. Try increasing the temperature setting to see if it helps. These are all simple fixes that take just minutes without special tools. If problems persist, a mechanic should inspect the heater core or sensors. Don't skimp on routine maintenance - just remember to change the coolant on schedule.
