其實呢條問題已經起ASV入主234X線果陣已經好想問
其實好多人都知豬同B9TL(只限歐三版) D水箱真係好嘈
而用E500車身既B9TL水箱聲更係嘈到拆天
想問下點解
係今多-_- |

前者中置散熱差所以Full loading個風扇加上水泵
個位又係車中間唔食聲就奇
B9....係咁架啦....都係長轉..... |

第一，上斜谷衡副偈會出多好多熱；第二，落斜狂用吹梳，吹梳啲油都要散熱，於是散畀冷卻水，經水箱放熱，正常嚟計主要係呢兩個情況令水箱風扇着
畀着一部新車落地嘅AVBWU都可以上上下斜聽到水箱風扇聲
但其實前置水箱咪一樣可以咁嘈，不論豪偈康偈都係咁
甚至啲人so-called唔怕熱嘅康偈，放落歐三躉以至E400/E500一樣可以風扇扯到盡嚟行
吉偈年代咪又係咁樣水箱同偈聲好似奏緊交響樂咁
根本就唔關位置又唔關副偈事
由頭到尾都係水箱風扇死咗個溫控功能，跟住咪fail-safe發作扯盡風扇轉數囉

B9死唔死十幾廿度都全開架啦！天才部部都死溫控咩....
鬼唔知前置水箱一樣噪，樓主問豬同B9你囉前水箱問咩事
係要研究既不如講下後置水箱散熱器做成尾箱溫度偏高既問題好唔好....吹得越勁越熱散熱排網越大越熱
你唔計黎D點會知B9點解好日都全力開風扇，真係唔知以為成街B9都死曬溫控
仲要你自己都講唔係幅偈做成，又要自己打自己咀話有2個原因.....自己講曬都有人拍手認真奇怪 |

你係要賴老九較到個風扇行一行，得，但係出面不論 B9 定 B10 一樣都有水箱靜o既例子。
講嘈，Trident KUD 一樣都有亂咁叫o既例子，又唔見你挖出o黎賴係廠方問題？
上面篇文都有講，富豪都因為個 thermal sensor 問題一度冇哂大英帝都o既生意，佢都要面對個問題。
但係賣o左出街o既車個 sensor short 起上o黎整唔整係個營運商自己決定，唔係富豪殺上門話同你搞就得。 |

Completely off the mark, you don't seem to have a clue how those radiator works.
Volvo buses in around that era (inc. other B7L-series in other market) has a hydraulic operated radiator, and their speed are regulated by a thermostat. The common problem is the thermostat fails every now and then, and when it fails, as part of the fail-safe design the radiator defaults to operate at maximum to ensure sufficient cooling is maintained, and hence, all the noise. So long as the thermostat remains dead and not replaced, which a lot of times they were not, the issue does not get rectified.
The problem is only fixed in about 2007/08 when the Mark 2 version of B9TL i.e. the UK 2-axle versions and mark 3 version of B7RLEs, et al, started to come along, which has a quieter electric-drive radiator in place of the hydraulic ones. |

現在都係噪，無當年咁震憾，而且非長期Full load，如果你話成街都壞我就唔認同啦，當然靜左好多近年的
而且風扇吹水箱，長期Full load只會吹D熱氣入機器空間內，無好處既，全面後置後己經唔係風扇開爆佢就當無事.....
正如改大水箱散熱面會引致機器空間溫度更高，確保散熱卻做成機器空間高溫都唔係好事.....當然都要講就算正常既Volvo好日子過左開冷氣溫度都係輕易Full loading把風扇
就算唔係壞左感應都是正常，就唔好講夏天必然全開既問題....
