Does anyone have the service manual procedure-instructions for replacing the drop-in oil filter-canister on the 2.4L ECOTEC motor? Is the filter-canister and threaded plastic cover installed as a unit, or does one simply drop the canister-filter into the housing and then install the threaded cover?
Does the plastic cover require replacement with each filter change? In addition, are there any other requirements associated with replacement of the oil filter-canister, i.e. replacement of o-rings? Thanks in advance.
Not from the GM service manual, but from changing oil myself a number of
times with this model Chevrolet:
The threaded plastic cover is re-used, permanent.
The filter-canister and threaded plastic cover is installed as a unit. Take the new filter in one hand, the cover in the other. Twist a little and the new filter snaps firmly or locks into the cover/cap. They will then be mated together snugly with no wobble.
Now, drop the new filter and cover together into the housing so that the
pointy filter end with the small O-ring points down and seats into the center point at the bottom of the housing.
Then, turn the cover clock-wise and tighten to about 25NM as I believe is printed on the cap, around the 32MM hex.
If you first drop just the filter into the housing and then apply the cover, the
proper filter-top-to-cover seating may not occur and you will bind down on and distort or compress slightly the filter element, thus reducing its effectiveness. You will not know this happened until you remove the filter at the next oil change. Crunched cartridge!
