Rexton 270xdi Cooling Fan Viscous Coupling

I have collected my Ori VFC with refilled 2 tubes of Silicon Oil worth RM80 inclusive of labor charge this morning. Obviously it is over engaging now unlike previously where it engages for about a minute then disengage during initial start- up. However the old one supposed ot engage again when temperature is rising but it wasn't. Now my Rex roars like a 747 when pickup fast and engages full time. I will need to monitor further if in case the refilled Silicon Oil would change its property or stabilize after using for sometimes. Frustrating in a way that I am yet to see a standard being defined to judge if a new one is aging too much and due for replacement or a re- cond one is still meeting the requirement. My thinking is an electrical fan is more precise in both its triggering and shut- off timings.

I am not fully convinced that the full time engagement of VFC would jeopardize the horse power or FC significantly. The load of VFC could be nothing to our powerful turbo charge Rexs.

For me,i knock it sofly at it base where the thermoregulator attached to open and knock it to lock it back.
Scare if i bend thermoregulator then it will not function normally.

Bro, appreciate if you have photo(s) to show how you open up the 'diamond shape' metal piece. By the way, where do you purchase the Silicon Oil from? If yes, can purchase and courier to me at my cost?

Huh! With my gross FC calculation of RM/KM, the full time engaged VFC is causing an increase of 8.7% in FC I have sent the spare BEHR VFC with exhausted Silicon Oil (ex- unit from Bro BK) for refill with one tube of 18ml Silicon Oil only. Yet to be ready for collection.

Bro,
Thanks for your call on yesterday about noon time. I learned quite a bit from you on VFC. You are the first DIY guy to have dismantled and re- install VFC without even loosen the fan shroud. It is amazing that you can do that by slotting your hand with wrench across the gap between 5 blades Mercedes fan.

I was in Ipoh 2day with Brosr3xt0n & rx270xdi which he come all the way fr K.L bringing the vacuum tube I require as all r rexton freak,v don't do nothing 2 my rexton so what v hv done is:-
1)change the complete clutch fan 2 Merc 9 blades.
2)clean the entire EGR system.
3)change the vaccum rubber hose tube.
So,this is the review of after changing with my own test drive fr 1 change 2 another.
1)after changing the clutch fan,I did a spin of the fan,yes it spin more freely than my ori rexton fan(bro rx270xdi pointed out that my clutch is leaking)so the best way 2 know the result is 2 test drive my own self,here it goes,a lighter feel & willing 2 go is the answer.
2+3)even better respond without much thottle lag as b4.
after dinner with this 2 bros,I drive home 2 Bukit Mertajam,what I can describe is sensational driving xperience,all the way in 5th gear,didnt even shifted 2 4th gear in the Ipoh K.kansar hilly hwy,my car when drive in this hwy nomally will b in 3rd, 4th,dn hill 5th,this already prove that my car run better than b4,this is only my few hrs of drive xperience which may not b 100% true,a further rview will b follow if any new find.
Thanks 2 the 2 bro's accompany n bro rex4585's concern. THANKYOU
