Question sa VIOS engine fan...

Conclusion? In short, it's normal. However, it begets further questions. Is the coolant not effective (remember this is a new car)? Is the engine running abnormally hot? I run it only for a few minutes in idle mode,.i.e, I'm not actually driving the car, just letting the engine run?

To eliminate any doubts, I'm just getting a Civic...

That is normal, either its cooling system is perfectly normal. Most engines today have to maintain its operating temperature to be more efficient. I think honda cars are the same. Halos lahat ng bago car ganon except fortuner propeller type kasi wala sya aux fan...remember when you operate the aircon the sequence of radiator/condenser fans varies depending on your setting or whenever the compressor engages the fan also runs even if your engine is cold. Some fans have 2 speeds to perfectly maintain the engine's operating temp and to minimize on and off operation.

I don't think it's a design defect in any way. It may have just been configured that way after careful R&D. The current Vios (being an entry-level sub-compact sedan) may not have the intricate circuits and intelligence to retard the operation of the fans until after the engine has been running. Just a nuisance, IMO... nothing to lose sleep over.

Oh and good choice on the Civic, though.
