i am changing my spark plugs this weekend.. and when i open the hood i see the three ones in the front but in the back how do i get to those? i can barley fit my hand back there.. i think it would be highly unlikely to fit a rachet back there either. any help would be apreciated

Unbolt the upper engine mounts (the mounts that anchor the top of the engine to the radiator support), get some help and pull the engine forward. Tie it off to the radiator support somehow so it'll stay put, then take the spark plugs out. Should take you just a few minutes.

Can you jack-up the back (right side) of the engine (if you use a wood block of course)? after removing the left side support.

alright thank you evansblue and gwampa ill try both of those things. ill get back to you guys.

How did you make out with the plug change??

What year Impala and which v6 do you have??

Tilt the engine forward and take off the front STB if you have one. The 3400 engine is a bitch for a spark plug change. Looking at 2+ hours easy

dang i was thinking about changing my plugs...i dont want to now

wish they could have made it easier for the 3400

HotSauce6226

Oh you can do it. A helper is good too

i have a 2005 impala 3400 v6 and i didnt have to do anything to the motor just used a ratchet with an extension and they came out just fine took me 30 min to swap out all plugs and wires.

I did my 2000 Malibu V6, but those 3 in the back were hardest and took longer. Best to use a mechanic mirror and a good spark plug socket that grips the spark plug properly (not to light, not to hard). I think I used a 5 inch extension and maybe a swivel. I used platinum plugs so they can stay in there a while. I snapped a plug wire - it would be best to have one of those tools for it. I'm glad I did change the wires though, because they are not too expensive and I found some corrosion at the coil side connections
