mga sir nagpapalit ako ng radiator fan recently and i noticed that the direction of the airflow of the fan was towards the engine, is this right? i thought it's supposed to be towards the radiator fins? tama ba o mali ang pagkaka-kabit ng rad fan ko? one more thing, pag umandar naman sya, few seconds (5-6 sec.) lang andar nya tapos hinto agad?..help!

The engine driven fan (yung may fanbelt) is supposed to drive air backwards. It will suck the air from behind the radiator.
For electric fans mounted in front of the radiator, it is supposed to force air into it (and the a/c condenser).
Typical rule of the thumb is airflow goes from the front of the vehicle going to the rear.

yah! that's true!
Towards the Engine, because if the vehicle moves, the air from the front grille moves In- the radiator suck by the FAN to Engine..

Yes, it(a.k.a aux fan) sucks the air from outside. It passes thru the
radiator, therefore it helps lower the coolant temp inside the radiator.
As per the fan connected to the engine, it's also designed to suck
outside air inward to cools down the engine.Last edited by XTO; November 16th, 2006 at 05:14 PM.

November 16th, 2006 05:23 PM #7Thats' right, ON sya sandali then OFF na. Helps keep the engine at normal temp that is if electric ang fan mo.
Pag umiinit na yun engine, On sya, then pag bumababa na temps...OFF na sya.
Belt driven fans are on if the engine is running...ika nga..belt.

kaya sandali lang din nabubuhay kung walang aircon kasi connected siya sa thermo-switch located sa radiator.
much better set-up na yon kaysa sa rekta(alwayz-on on "on"-position) easiy on the carbon brush)

i changed from stock airbox to SRI - when traffic syempre the aux fan/rad fan heats the sri as well. any suggestion to avoid heating the SRI? Well of course to change it back to stock airbox is another solution... May mga DIY ba dyan? thanks.

coveran mo ng heatshield ung sides ng airfilter mo facing the engine.
