Just wondering coz i just had mine totally removed and replaced with a new silicone oil. I used GMB and was able to fill 5 vials, as in nag-umapaw. Then napansin ko na parang palagi nalang naka-engaged ang fan ko. What could be wrong? Hindi kaya pangit na brand ang gamit ko? or sumobra lang sa silicone oil?

September 2nd, 2005 05:34 PM #6AFAIK, the silicone oil is the main agent inside the fan clutch that promotes the engagement of the fan on high temperature. When your vehicle's temperature is cooler, the silicone oil is soft, propeller turns on a freewheel manner. At high temperature, silicone oil hardens, causing the fan to grip so it goes along at the same speed with the engine's rpm. So the higher your rev is, the faster the fan turns. You would notice it coz it produces a vacuum cleaner-like noise. So basically, as the silicone oil hardens during high temp, the fan engages otherwise, the oil softens in cold temperature and the fan dis-engages.

September 2nd, 2005 05:38 PM #7ung clutch fan kasi is mostly sa mga rear-drive vehicles...ung nakatapat sa radiator na umiikot kasama ng makina...freewheeling un para daw di mag-drag ung engine..
ung oil is for the moving parts inside that fan...

September 2nd, 2005 06:23 PM #8silicone oil tawag dun, it is sold in vials. mga P65 ang isa. pinapalitan pag notice mo na parang hindi na masyadong kumakagat ang fan mo during engagement. Or if your vehicle tends to overheat, that's one of the things you must check.
problema ko is, i dont know kung how many vials needed to totally replace the silicone oil in the fan clutch. kasi mukhang nasobrahan yata yung sakin eh, kasi palagi nalang naka-engage ang fan kahit malamig ang engine temp. ang ingay. siguro wala nang magalawan ang mga moving parts inside the fan clutch dahil punung-puno na ng oil

September 2nd, 2005 06:32 PM #9ask ko lang din po, panu po pinapalitan? panu po matetest kung "engaged" ung clutch fan?
sorry, ha, kasi my father, sinusumpa ung free-wheeling na clutchfan, kay pinafix nya ung sa old delica ko...(siyempre sulsol ng mga mekaniko-mekanikohan)...now kasi my ride is a liteace 2c-t ang makina, e good namang di fixed ung clutch fan...
kasi habang under repair, isasabay ko na din ito...
thanx!

September 2nd, 2005 06:47 PM #10yan palagi remedyo ng mga mekaniko, kase tamad sila maghanap ng real cause. pag naka-fix kase, kawawa ang engine at fan mo dahil palaging naka engaged, tapos matagal pa mag warm up. resulta, poor fuel efficiency at maingay.
binubuksan lang yung fan clutch, split it into two then lagyan mo yun ng silicone oil. mahirap pag sealed type coz hindi pwedeng buksan, kelangan palitan talaga ng bago ang whole clutch. malalaman mo na engaged na ang fan when it reaches the certain temp, mga 40-50%, then the fan starts to turn producing loud noise pag ni-rev mo. tapos tatahimik ulit sya pag baba ng temp

September 2nd, 2005 07:18 PM #11un ba ung parang loud bass-y sound na parang humihigop ng hangin pag ni-rev mo ung engine?
sinabi mo pa, kaya parang laging labor ung makina ng delica ko lalo na pag above 100kph...
di lang ako makapiyok sa tatay ko....masyadong nagmamagaling din kasi,e...

September 4th, 2005 07:06 PM #13Around two to three. But this is on a 4D56 diesel engine. Be sure to replace the big O-ring so you won't have leaks. And use impact screws driver para madaling nag alis and tight ang mga screws. Sa Denso sa Banawe mayrun.

September 5th, 2005 12:26 PM #14thanks afrasay!
how would we know na tamang-tama na yung silicone oil na nilagay ko without mounting the fan back? pwede kayang pakiramdaman lang by turning the fan by hand? nakakapagod kase pag tanggal-kabit eh
is it true na pag cooler temperature, pwede mo pigilan ang fan with your hand when starting the engine? i was thinking kase na its logical coz silicone oil must be softer by then.

September 5th, 2005 07:23 PM #15Sir Afrasay, sa Revo na 7K-E ang makina, ano kaya ang nakalagay na fan clutch, is it sealed type be o hindi? And twing kailan mo dapat palitan ito in terms of kms na naitakbo nito? Yung sa kin kasi maingay din pag-andar nya and nasa 90kms na itinakbo nya. Do you think kailangan ng lagyan ng silicon oil ito?

September 5th, 2005 10:31 PM #16Hindi noise supressor ang silicone oil. If the fan still 'freewheels' even when the engine is hot, that is the time to add oil.
Even seemingly 'sealed' fans can still be opened up for refills. Afrasay's mechanic cousin Ferdie can probably do it for you if the mechanics in your area wants to take the lazy way out and just weld the fan solid to the shaft.

September 6th, 2005 08:45 PM #17just fill up one side pag na biyak mo na yun mechanisim. yes, you can hold the fan while someone starts the engine. the silicone hasn't expanded/harden yet when the engine is cold. i don't know if the fan in a 7k engine is serviceable. you'll know it if you see screws around it.
