then ibang tao ang maglagay to ON. tingnan mo kung mag turn yung fan malapit sa radiator. dapat hindi mag turn yun kasi patay pa naman ang makina mo.

Try kong silipin kung ano yon. Minsan lang kasi nangyayari.

Thanks. I'll inform you about the situation asap.

It is possible that two fans will run if you turn on the switch if the following conditions are met.
1) Aircon is on
2) Engine is already warm or hot
The Engine fan should only turn-on if the temperature of coolant is already above the required operating temperature (usually 60 deg C). If your engine fan does not turn-off, it is possible the some auto electrician has by-pass the temperature switch. If this is so your electrical fan is showing signs that it will break down. Have a qualified Honda electrician to revert set-up to original one

i have the same experience sa rav4 namin...

pag nag oon ako, although yun talaga totally on na sya napagkakamalan ng mga tao na un valve ang maluwag kasi ganun ang tunog. yun pala every time aandar ang aircon (compressor) bah? dun nangagaling ang tunog... pag off ang aircon nawawala ang tunog eh..

share ko lang baka same to ng naeexperience mo...

my two cents lang po:

most probable bet would be the engine/aux fan, this is likely controlled by a temp switch sa ilalim ng radiator. two possible reasons kung bakit nag-oon siya even before you turn on the engine:

1.) if the car is second hand, the temp switch could have previously failed and the electrician of the previous owner simply bypassed the temp switch and connected it directly sa ignition, hence palagi siyang naka-on. imo, there are at least two reasons why this is not recommended: a.) the engine may have a hard time reaching the optimal operating temperature kung even before magstart siya is may fan na agad, b.) the engine/aux fans were not designed to operate continuously, baka umiksi ang lifespan ng motor niyan. replaced one on a previous car ('89 galant) and it cost around 3K.

2.) check your radiator, baka kulang sa water/coolant or may leak. same thing happened with our accord vti-s, and kahit patay na yung engine the fan was still running. kulang pala sa tubig ang radiator (maybe it's the car's way of crying out "uhaw na ko!" hehehe).

update ka lang po ng developments para maka-input pa ibang tsikoteers.

Sa ngayon, di lumalabas yung problem. Okay naman yung coolant. Wala namang leak. The car isn't a second hand (bnew nung mabili) and it is maintained naman sa casa. I don't think na may ginalaw sila don.

Possible nga sigurong suspect dito is the aux fan/motor na pinalit sa nasirang original. Binili namin to sa surplus sa banawe at dun namin pinakabit. Mahal kasi yung brand new. Matagal na ring nakakabit to. Sa ngayon, di pa bumabalik yung problem. Wala pa akong pinapagawa. Di ko pa rin alam sa ngayon kung yung aux fan nga.

Anyway, i'll update you na lang. Thanks.
