Radiator fan motor failure
尽快预约维修。今天无需停驶。
若置之不理: Left alone, the engine overheats whenever the car sits still, and a boiled engine is a head gasket.
何时停驶: Stop and let it cool if the temperature gauge climbs into the red or the coolant boils, and do not drive on until the fan is fixed.
涉及车型年份: 2004-2008
症状
- Temperature gauge climbs in traffic, then drops once moving
- Air-conditioning turns warm at the same time
- Fan does not run when the engine is hot and idling
- Coolant boils or the warning light comes on in a jam
原因
The radiator fan motor seizes or slows with age. At speed the airflow through the radiator hides it, so the car behaves normally on the highway and overheats the moment it sits still. This is the fault Gen-2 owners mention most often when they talk about overheating, and it is cheap compared with a head gasket.
解决方案
Ask a workshop to confirm the fan runs at both speeds with the engine hot. A replacement fan motor with blade is sold for the Gen-2 as an APM-type unit, so the part is easy to find. If the car has already boiled, do not keep driving it: stop, let it cool, and have it towed or checked before the next trip.

This is the one quirk on the page that can cost you an engine. The gauge is the only warning you get, and it lies while the car is moving because the airflow does the fan’s job.
If the temperature climbs in a traffic jam and falls as soon as you accelerate, stop treating it as a quirk. Park it, let it cool, and check whether the fan runs. A fan that is silent with the engine hot and the air-conditioning on is the answer.
The part is cheap. A replacement fan motor with blade is listed at RM178 from a Malaysian parts supplier, and the rest of the band is labour and coolant. That is a small bill next to a warped head.

社区笔记
The Lowyat.NET Gen-2 thread names the radiator fan motor as a repeat failure, with one workshop contributor saying they replace it preventively on used cars.
