Implications Of Connecting Radiator Fan From Ignition / Today, I Found Out For Sure That, Connecting Radiator Fan Directly Is Not Good ! / Don't Top-up Your Radiator With Water. Use Engine Coolant (2) (3) (4)
Radiator Fan by Babaigwebishop(m): 8:54pm On Jun 21, 2020 |
Hi Nairalanders, I need your guidance on my sienna 2000 CE. The radiator fan starts and remains on from the time I start the engine until I put it off (that was how I bought the car ). Is this ok given that I use it to travel without any issues (not commercial) and if I need to correct it, i.e the fan, should the thermostat be replaced (if it is still there. don't know if that is possible ![]() And my coolant keep going down with refills every other day and no visible sign of leaks anywhere. Please guru's in the house, your input will be highly appreciated. |

There's every probability ur fan control module must have been bypassed and motor connected directly to ur battery. If it's OK well, the answer is no, if it can cause harm, answer too is a no but ur engine might take a longer time to reach optimal operating temperature(ie running at the lower temperature for longer than necessary). Revert to manufacturers design if you can for better performance. As for ur coolant, there's definitely a leak sumwhere hence the need for frequent top up. Just keep refilling till ur ready to have it examined. 1 Like |

Babaigwebishop:Don't use your car in this condition if you don't want to add more to the issue it already has o cos a fan that is ran direct has more risk of failure anytime cos constantly running will reduce it life span,cause engine bore wash and also cause issue for the alternator as well . Coolant going down if neglected too can cause headgasket leak later on . 1 Like |

autologic:We shouldn't always blow things out of proportions. If ur theory of running fan directly affects the life span of the radiator fan motor,then one can also say using AC would affect the lifespan of the fan motor as well cos the fan kicks on whenever AC is in use....what do u think ![]() 3 Likes |

double3:Nice observation ,however what makes the big difference btw the two different circumstances Is the word control With ac on ,Fan Is still under controlled either from a one computer somewhere or a thermoswitch and is running with controlled speed from zero to 100 and even trigger off completely as dictated by it controlling master inlike when same fan is ran direct when ran direct with no control and running perpetually at 100% capacity till it work itself to death . |

autologic:I know someone who has been running fan direct on his Corolla for over 6 years and fan is still working. He said the AC is also much colder than when it was on thermostat. I'm not saying removing the thermostat is good, but under Nigerian circumstances, and the likelihood of overheating, then in the long run it is the more affordable option. 2 Likes |

ModelX:Point of correction ,no relationship btw Fan control and Thermostat ,there are different entity entirely ,what turn on fans are electrical actuators and modules . Working as automotive servicing sector for over a decade , I have learnt that u can be easily led astray make vital analysis and decision based solely on the customer "stories" as vehicle repair history ,cos u will discover holes in the stories later on ,even on this forum we have seen people crying wolves when there is non and even vice versa after the issue has been seen physically. I try as mush as possible to align my analysis & thought process based on scientific fact and figure and not sentimental stories, however everyone is free to believe in what he "believes" work for him but not to be spreading old wives tales .

ModelX:You seem to have comprehension issues, he said he's been working for over a decade, it's only Google mechanic you can make of his explanation. |

I appreciate all your genuine contributions, Thanks. Though I later realised that the coolant issue I was having was as a result of a faulty radiator cover, it looks physically ok to me though but happened to be the cause of my worries all these while. I have not topped coolant ever since I replaced the cover. |
