Trapped air in the cooling system can sometimes account for this but you are indicating that you are getting heat, at times, which would indicate that coolant is flowing. There is a加热器控制阀您想确保阀门完全打开。如果不完全打开,则将加热的发动机冷却液传递到加热器芯将大大减少。确认加热器控制阀完全打开后,请检查通向阀的加热器软管的温度。像散热器软管一样,软管应该很热。如果阀门打开,软管很热,乘客舱中的热量仍然不足,这意味着仪表板中的混合门被卡在错误的位置,不允许在加热器芯上流动气流,和/或加热器核心本身已被插入,因此不允许足够的热发动机冷却液循环。如果您希望您的机械师万博体育入口诊断并修复您的无热条件请联系YourMechanic万博体育入口以进行移动访问。
