Chevrolet Trailblazer 2.8 Duramax - Fan Clutch Silicone Oil Refill and Installation.

Late Upload. Quick Tutorial Only for beginners. D-I-Y muna dahil naipit sa ECQ. FYI: Some fan clutch assembly are disposable and can not be refilled with silicone oil. I recommend buying a new one if needed. How to test your fan clutch? 1.) Try to spin the fan with your hand multiple times and it should feel some resistance. Make sure the engine is not yet warmed up. If the fan rotates more with ease, it may need to add silicone oil. Take note do not add too much silicone oil. (Subukan paikutin ang fan gamit ang kamay nang maraming beses at dapat medyo maganit. Tiyakin ang engine ay hindi pa nag-init. Kung ang fan ay madaling umikot, kailangan magdagdag ng silicone oil. Tandaan na huwag magdagdag ng labis). 2.) Start the engine and hear some noise of the wind coming from the fan. It is engaged and wait for a while to freewheel automatically. If did not freewheel in a given time, rev the engine up to 2000rpm. The fan clutch must be freewheeled at that moment. Otherwise, it is overfilled of silicone oil or damaged. If this occurs, drain some but do not drain completely or I suggest to buy a new fan clutch. (I-start ang engine at maririnig ang ingay ng hangin na nagmumula sa fan. Ito ay nka-engage at maghintay ng ilang sandali upang mawala. Kung hindi nawala sa oras na iyon, i-rev ang engine hanggang sa 2000rpm. Ang fan clutch ay dapat mag freewheel sa sandaling iyon. Kung hindi man, puno ito ng silicone oil o sira. Kung nangyari ito, bawasan lamang pero wag uubusin o palitan...
