Pros and Cons ng naka-rekta ang engine fan

[Chinoi]

sa engine ba nakatutok ang fan? dba sa radiator?

Sa Lancer ay nasa likod ng radiator ang fan at pahigop ang hangin galing sa harap ng radiator. Ibig sabihin nalalamigan yun tubing ng radiator at malamig din hangin pasok hood. Nasa loob ng hood yun engine.
Di ko sure sa Vios kung yun fan ng radiator ay nasa harap ng radiator. Pero sure ako papasok ang malamig na hangin galing sa labas at dadaan sa radiator papasok hangin sa hood.

ah ok. check ko ung sa jazz kung saan direction hangin ng radiator fan.

sapat na ba ung hangin galing ng radiator fan na bumubuga sa makina para maapektuhan ang warm up time ng isang makina?

just a recommendation, since your aux fan is wired directly at the ignition switch (which tends to start operating once the ignition turnon) instead of wiring it into the ignition switch, re-wired it and put a separate switch, so that you can turn it on and off on times its just need to be operate. yung akin nakaganyan, may switch siya, so kapag half na yung temperature gauge ko dun ko lang siya bubuksan then pagbumababa,...papatayin ko na ulit...pangit kasi nakarekta,

now why would anyone want to turn his aux fan on and off manually, when a temp-dependent switch can do it automatically and more effectively?
malimutan mong i-on yan nang isang beses at warp ang head gasket... and when you have a guest driver, kasalanan pa siguro niya kapag..
re-wiring the aux fan back to auto mode is not difficult..

^ LOL. ginawang human thermostat. Bakit nga ba hindi nalang ayusin ang thermal switch.

Halos lahat ng ng rad fan nasa likod ng radiator, yung nasa harapan or tabi sa aircon condenser.

Kaya minsan kapag busted ang rad fan hindi mo kaagad mapapansin kung nakabukas ang aircon kasi some of the air of condenser fan damay ang rad.

How about ung fans na engine driven. Like sa revo namin pagka stat naikot na agad yung radiator fan since engine driven sya

1. many modern direct-driven fans have a viscous coupling, sabi nga ni 12 volts. personally, i find this viscous mechanism more of a headache than an advantage...
2. most engines have a thermostat inside them, whether their fans are direct-driven or electric aux fans. the thermostat interferes with radiator-engine block coolant exchange, so that the block gets to optimal temp faster..

Maybe for colder regions. Rad fan is designed to run at single / full speed.

Again, Its the hysteresis of the thermostat that delays reaching operating temp .

no.
remember that in starting a cold engine, yung bumubugang hangin sa makina ay malamig din..
also, the heat coefficient of air vis-a-vis engine block metal, is so very small.. but if you can manage to vastly increase the surface area of the engine block, then we're in business. look at the air-cooled VW or most motorcycle engines..
that's why the designers included a thermostat in the engine block.

Sa radiator po.
