convert radiator fan from mechanical to electrical

[sirkosero]

mga peeps, especially sa mga old schoolers, nasubukan na ba ninyo i-convert ang radiator fan ng old school ride ninyo to electrical? yung parang sa modelo na sasakyan na may thermal switch na umaandar lang pag mainit na yung radiator? ano ba pros and cons nito or mas maganda ba kung stick to mechanical? yung mechanical kasi lagi na lang umaandar pag start ng engine kasi mounted sa pulley eh.. help please

sir,

i've than that before in our silver ed corona. after a while, i put back the mechanical fan. mashado kasing nakakadrain ng electricity yung kinabit na radiator fan ko eh. I just opted for an additional smaller auxillary fan placed at the front of the radiator where I can manually switch on especially during heavy traffic.

pro's bawas load sa makina kapag high speed, pag low speed di kulang sa hagok ng hangin para sa radiator. constulad gna ng sabi ni bosstl lakas drain sa battery lalo na pag maliit ang alternator, mga 50amps less. pero recommendable naman na magpalit to electric

i think mas maganda kung meron kang thermostat circuit that senses the desired temperature then triggers or actuates the fan instead na u have to switch on everytime that u feel it's getting hot under the bonnet  

here's an electronic circuit i found. i have not tried this personnaly but with regards to your project, you may give it a try.

pay attention to the LED 1 which you can trigger a relay that will switch on your intended load which is the fan itself.

HTH!

sir ano po engine nila? sa 4g32 aka saturn pwede lagyan ng thermostat...

why would you convert your radiator fan to electrical? its designed that way for RWD cars. if overheating is your problem then check the cooling system.

my friend's vannete had overheating problems also. the "kanto mekaniko" suggested to add another aux fan while the problem was only the main fan's (engine driven) "clutch" or something that engages the fan to spin faster.

imo, its better to stay away from conversions as much as possible.

elvin, my car is the successor of the saturn. astron. 78 model lancer. yup im planning na may thermostat. yung sa saturn ba nilagyan mo ng electrtical na fan?

jason/non-vtec, kasi po gusto ko ma-maximize and power ng sasakyan tulad ng sabi ni blackblood na para makabawas sa load ng makina lalo na at high speed.

sir clyde, maganda yung circuit. may isang circuit din kaming ginawa para temp. based pero sa ibang fan namin nilagay...

clutch fan tawag dun. these spin at variable speeds depending on the engine speed. kung sira na kaya pa minsan i-repair by replacing the silicone oil inside. minsan tho di na so palit nalang.

most l300's, pajeros, starex's and other big cars have this. as well as suv's like the expedition...
