Changing Spark Plugs on 2009 Aveo

[smaxkid]

Here's the one for 04/05 (written back in 06, so the other years didn't really exist yet), but I'm sure the general guidelines for your car are the same... viewtopic.php?f=22&t=58

Didn't work for me. Couldn't get the cover off and then one of the bolts snapped off putting everything back together. I'm gonna go cry now and take my car to the dealer Monday.

I like the NGK solid copper plugs, I replaced my stock ones at 50k and even tho they were worn they still worked great.

MY AVEOS 2010 SEDAN 1.6 (103HP) THE OWNER´S MANUAL INDICATE PROPER -STOCK- IS NGK SPARK PLUG NUMBER BKR6E (calibration1.0 to 1.1 mm). I REPLACE WITH BKR15E AND WORK PERFECTLY. SOMETIME I PUT AUTOLITE IRIDIUM BUT I BEEN HAD PROBLEMS TO COLD START.

BKR15E is a much colder plug. With NGK, the higher the #, the colder the plug and vice versa, but for most other mfgs, the higher the #, the hotter the plug. If you get fouling come winter or notice alot of carbon building up, go to a hotter (lower # BKR#E) plug. The rest of the letters should be the same as they describe the length, thread size, and electrode specs.

I need advice on changing the plugs on my 2009 Aveo - I got the ecotec cover removed, then what? its plugged in on the right side and I see two torx screws - what would be my next step?
Thanks!

take out the torx screws to remove the coilpack. Then take out the spark plugs underneath.

that bridge you speak of is the coil pack, its directly on the spark plugs instead of on the side of the block (hence no plug wires)

Since I haven't done plugs on my Aveo, I found this out on the interweb, supposedly from a call to a dealer:


A) when facing the engine, look down at the black plastic cover on top of the engine, underneath that cover is the coil, and then below the coil bridge is the 4 spark plugs.

B) See the white letters ECOTEC, at the right hand side of this center black plastic piece is a ARROW sign ingrained in the top of the black plastic pointing to your right. THUS you need to slide this black plastic center piece to your right, it will only move about 1/4 of an inch to the right or so at most.

C) then put your fingers underneath the portion of the black plastic piece(ECOTEC) that is now slid out to the right and sticking out about a 1/4 of inch; now pull or lift straight up with your fingers underneath that black center piece. It is snug but do not worry you will not break it, it should pop straight up for you. Now you can see the coil bridge on top of the engine.

D) Then on the right hand side of the bridge coil there is a electric type plug that goes into the right hand side of the bridge coil, you need to unplug it from the bridge coil. You will need a 40 Torx bit to unscrew the two screws that are holding the coil bridge in place over the spark plugs.

E) Then once you unscrew those two screws, you just lift the coil straight up or pull straight up.

D) Then looking down inside the top of the engine you will see the 4 spark plugs. You will need a 5/8 spark plug socket to unscrew the spark plugs.

Hope it's a help.

Happy Driving,

thanks, rabbit - but do I need to disconnect or unplug it before I remove the torx's? and also, how difficult is it to persuade
the coilpack to lift up? tks

[petrified.rabbit]

it "pops" off, no real persuasion. just a gently even pull. I would unplug it to make life easier, you are going up maybe 5 inches before you could "fold" it out of the way attached so to speak, to it would be easier to unplug and remove than to leave it attached.

well I tried 'prying' the plug away and off but it didn't move much but will try a gently even pull as you suggest,
and I understand from what you wrote that it WOULD be easier unplugged so will try it again...
thanks!
