PS your auto parts store will recommend the right iridium plug Toyota
recommends – they come pre-gapped and iridium tipped plugs are not meant to
be bent and played with for gapping like other plugs. Be careful
installing so you don’t accidentally drop the plug and change the gap
and resist the temptation to be cheap. This job is too hard to waste time
on cheap plugs for sure.
Jeff brings up a GREAT point that the (very) difficult bracket behind the
intake manifold has two bolts, one to the manifold and one to what is
either the engine block or another bracket. You may find it much easier to
remove the other bolt. Just be careful pulling the intake out as it will
still have the bracket attached. This is about a 375$ to $400 dollar job
at a dealership plugs included and they are not cheap. Given the
difficulty of getting the intake off, don’t beat yourself up if you take it
to the dealership. If you’ve done several of them you get good at them but
this will be hard if this is your first time. This is NOT your
grandfathers spark plug swap for sure. I don’t intend to do this again
until another 100K miles or 10 years.
This is why I had the mechanic do this job, They Charged us $462.66 we had
a knocking sound I was fearful was a valve but , that knocking has seemed
to go away after this repair.
Thank you for this post .
How long in real time did it take? What is a good way to verify the
dealership actually changed those back 3?
You sir are a GOD, thank you so much for saving my family $400+, did it
this weekend and life is good.
Do have a ball park figure on what the dealer charges. because you have
convinced me that I’m to old and out of shape to do this.
Great video that saved me an extra day of cussing at Toyota. At couple
things that helped me:
– I could not get at that top bolt on the rear bracket on the manifold and
found it easier to remove the lower bolt on that bracket.
– Unclipping the wire bundle that runs across the top of the manifold and
tying it up helps with access.
– The connector clips going to the spark plug sockets are poorly designed
and it was easier to pull the socket out of the well before unclipping the
rear ones.
Thanks for doing this.
thank you for posting this!
Del: your video is excellent as I have a 2004 Sienna too. I could not
remove the 12 mm bolt that was attached behind the plastic manifold .
Alternatively I lifted up the plastic manifold 5 inches up to make room to
reach the spark plugs. Mission finally accomplished.
Del, what brand of Iridium Spark Plug do you recommend ?
10:00 min “This bolt here” is the PCV VALVE, thanks I just wondering where
is located. Thank good video A++
PS- I missed a vacuum connection when reassembling which triggered a lot of
engine codes. Once the uncoupled hose was found I was able to clear codes
with a standard cheap OBDII automotive diagnostic tool and the plug swap
was a success. Remember also if you plugged your intake holes like I did
with paper towels to block dropping things down into the engine, don’t
forget that you have to remove them when reassembling. Good Luck!
