First you should keep an eye on your temperature guage when you drive it around, and just before you stop the engine. This will tell you if your cooling system is adequate. Besides, apart from running your battery a bit, it does no harm for your radiator fan to work more than needed. Working less is the real trouble. |

Spark2:Your observation is correct Your car will burn more fuel cos the thermostat that controls the temperature has been disabled. Tell him to return it to factory settings. Your fan shouldn't run immediately you start the engine, especially a cold start. The thermostat decides at what temperature it should for optimal engine performance 3 Likes |

Have your CAN (connectors) checked. It could be an electrical issue, depending on the model. Speaking from experience. |

Electrical fault. At least that was what I was told when the same thing happened to me. Took it to an electrician and it was fixed in a few minutes |

My Range Rover Velar does the same thing. It's good for the cooling system. But get a scan to be double sure. My Velar does that but my Autobiography doesn't, so I might be wrong about the cooling system |

I think it's normal, and also good for your engine so it won't overheat [Qquote author=Spark2 post=133445302]My mechanic did some engine repair. He changed valves, bearing, rings and top gasket. He disconnected a cable from the thermostat so my fan runs immediately I start the engine, and stops about 3 mins after I stop my engine. He told me that this is essential for the valves to settle. And as well to avoid overheating. He said after 3days drive, I should come so he connects it back. I’m not comfortable with this. I do not even understand why it has to be so. I’m thinking the engine, temperature and cooling system cannot work optimally with this. I want to connect back the wire (he showed me). But I need advice from an experienced person. Pls help assist with an advise sirs.[/quote] |

Before your "Kazeem" disconnected the wire from the thermostat, was the fam kicking in after the engine had run for some time? And going off on its own after running for some time even when the engine is still running? If yes, reverse that connection your "Kazeem" did. After the reversal, let the engine idle for some time to see if the fan will kick in while your eyes ar on the temperature gauge to ensure it doesn't get to the red zone. If it kicks in at about 90 -100 degrees and goes off when the guage returns to 85-90 degree, it means you are good. The engin cooling temperature is not supposed to start running immediately the engine starts running 3 Likes |

My Volvo XC90 does the same. On extremely hot days, after turning off the engine the cooling fan runs for 2-3 mins before going off... Totally normal for motto wey kazeem never put hand. When I turn on my engine, the fan doesn't run immediately. It waits till things get hot before kicking in. |

voortrekker966:Yes, stop this Kazeem mentality . Engine doesn't break down in a day, it deteriorates with time. Optimal performance is key to long lasting engine 2 Likes |

I'll advise you change the fan, but first let an electrician carry out a diagnostic and assert that there's no electrical problem or breech somewhere. |

Condenser switch is the problem, as I experienced this issue 4 months back with the same Mercedes. Tell your mechanic to check it and change it as mine is working fine without problems. But as you change rings, your engine son dey weak gradually. |

He has disconnected the thermostat. Find a ladipo rewire to do it for you. I also doubt this mechanic of yours a a certified benz mechanic cos lol.... I never hear dis kind tin b4! Benz no be Toyota o... If ur fan is on direct, it'll run ur battery life down and reduce fan durability. Imagine driving at night steady.... With AC on and headlight with that loud fan on direct.... Aswear ur battery won't last! |
