问：我有一个99 cadillac Deville，可以保持暖气。

The most common causes of overheating include low coolant level (including that due to leaks), a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt. Certain engine faults, such as a leaking head gasket, poor engine running condition or exhaust blockages can also cause overheating. If you desire that this overheating problem be diagnosed by a certified Mechanic, dispatched by万博体育入口right to your location, please request an引擎过热诊断响应认证的机械师将为您解决这一问题。如果您有其他疑问或疑虑，请随时重新接触万博体育入口因为我们一直在这里为您提供帮助。
