Spark Plugs - so hard for 2003 V6 #825924 07/19/07 04:08 AM

Is it me or is it really hard to change the spark plugs for 2003 V6?

Some of my other cars, the spark plugs are right on top of the engine.

I know what tools to use but the length of the socket wrench has to be the right size. Anyone has pictures of the tools and length that you use?

Also, I was able to locate 3 on the driver side. Are the other 3 under some type of square sensors? I know they are under the air intake.

Any tips on the spark plug on the driver side that is close to the window? That one seem really hard to get to.

I am using Bosch and they recommend .44.

Thank You

Clark

I've done MANY tune ups on the 5VZFE..

Don't be afraid to move stuff out of your way to get to the spark plugs..it'll all bolt right back into place <img src="/forums/images/graemlins/smile.gif" alt="" />

I use a 6 inch extension, on a 3/8' drive wratchet, and have never ran into any problems..

Like I said before, don't be scared to move things out of the way to get to where you need to work on!

Look in our maintenance section, has a great DIY:

or you can look here too:

I would return those Bosch plugs ASAP. Our truck don't play well with those plugs. Go to the $tealer and get some OEM Denso or NGK plugs or you'll be sorry that you didn't.

Just to clarify, that should be .044"

X2 on using the factory plugs vs. anything else

Oh, and that first writeup is the best one <img src="/forums/images/graemlins/ignore.gif" alt="" /> <img src="/forums/images/graemlins/shiner.gif" alt="" /> <img src="/forums/images/graemlins/nana.gif" alt="" /> LOL

Back when I had my 4Runner (somewhat similar engine bay and placement) I had to use a handful of extensions and a u-joint to get the plug nearest the firewall out of the hole.

I recommend using a good anti-seize and the "vacuum line" trick to start the plugs back in the head. I have no idea what the torque spec is, but snug and a quarter turn worked fine on my 3.4 V6. Nothing sucks more than trying to heli-coil a stripped spark plug hole. Well, almost nothing anyhow.
