What are the reasons for the Roewe RX5's heater not being warm?
2 Answers
Roewe RX5's heater not being warm is caused by: 1. Engine cooling system failure; 2. Poor operation of the heater control mechanism. Taking the 2020 luxury version of the Roewe RX5 as an example, its body dimensions are: length 4571mm, width 1855mm, height 1719mm, with a wheelbase of 2708mm. The 2020 luxury version of the Roewe RX5 has a front suspension of MacPherson independent suspension and a rear suspension of longitudinal trailing arm semi-independent suspension. It is equipped with a 1.5L turbocharged engine, with a maximum horsepower of 173ps, maximum power of 127kw, maximum torque of 275nm, and is matched with a 6-speed manual transmission.
I've been driving the Roewe RX5 for several years, and the time when the heater didn't work in winter really gave me a hard time. Let me share some experience. The most common issue is insufficient coolant or air bubbles, which prevent heat transfer; check the fluid level after the car has been parked overnight—if it's below the marked line, that's the problem. A stuck thermostat is also common; it prevents the engine from warming up, so even though the temperature gauge shows normal, there's no warm air inside the car. A clogged heater core is even trickier—not changing the antifreeze can lead to debris buildup, blocking airflow. A faulty AC control module is another possibility, where settings are messed up or sensors are broken—try restarting the system. Leaks in the ducts or a slow fan can also weaken the heating effect. That time, I took it to the 4S shop for inspection, and they found it was a thermostat issue—fixed it for a few hundred yuan. I recommend owners get a maintenance check before winter to avoid freezing on the road—it really ruins the driving experience.
