*! Now pay attention - here's were you can screw up royal!
With your hand, install
new oil filter. If it seems even slightly hard to turn, back it out! You are crossing
threads. Most filters have an instruction printed on them to give
filter one more turn after
gasket has made contact.
Here's what I recommend: screw
filter on until its "hand tight". Then use
oil filter wrench to snug it up another 1/8 to 1/4 turn. This is critical!
When
vehicle is running,
oil pump puts
oil under pressure. If you don't install
oil filter tight enough,
oil will come gushing out. If that happens shut down
engine immediately! Without oil, an engine will lock up within seconds.
The first time I changed my oil, I used
filter wrench to tighten
filter as tight as I could get it. Wrong! The next time I went to change my oil, I couldn't get
filter off. Luckily I had plenty of room around
filer, so I hammered a screw driver through
body of
filter and used
handle of
screw driver to turn
filter off.
Warning! Don't over-tighten
filter. Follow
instructions above carefully!
- The GM dual-overhead-cam EcoTec engine has an unusual oil filter located on top of
engine. Remove
engine air intake hose. That's
oil filter canister just to
right of, and below,
end of
open air intake tube. Use a proper size wrench to remove
canister lid. This engine uses a special filter cartridge.
Step 3. Add
new oil.
Locate
oil filler cap on
valve cover. I've seen newbies pour motor oil in everything from
master brake cylinder to
radiator cap. Make sure you have located
the oil filler cap. Remove
oil filler cap.
When pouring
oil, you would be wise to use a funnel between
oil can and
valve cover oil filler hole.
How much oil should you add? Look in your cars owner manual. Most engines have a capacity of four or five quarts. Don't overfill
crank case. When you run
engine
extra oil will be blown out through
PCV value, possibly stalling your engine.
Tip: If you don't know
oil capacity of
engine, add four quarts, then check
oil level, if it's a quart low add another quart.
Replace
oil filler cap.
Step 4. Start
Engine.
Yes, I know, I said there where only three steps. You're finished, this is not really a "step".
Start
engine and make sure
oil warning light goes off. Look under
vehicle to make sure oil is not leaking out. Turn off
engine and let it set for a minute to let
oil drain down to
crank case. Then use
dip stick to check
oil level.
How to check
oil level: Remove
dip stick, wipe it clean with a rag, reinstall
dip stick. Make sure
dip stick is in all
way or you will get a false reading. After a few seconds remove
dip stick and examine how far up
stick is covered with oil. Most dip sticks have a "full" mark printed on them.
Note: I find
best way to dispose of
old oil is to use a funnel to pore it from
collection pan into
bottles from which
new oil came. When I get a big pile of used oil bottles I bring them to
oil recycling center. Be sure to mark
used oil bottles so you don't accidentally think they are new oil.
