spark plug replacement

D

Devin Nelson

So this evening I went out to do my 30K mile maintenance - Ok at about
35K miles. In attempting to replace the spark plugs, I was suprised
to find that I cannot get the wire/cover off the spark plugs. This
rubber boot around each of the spark plugs stretches several inches
when I try to pull it off. Can anyone share the trick to getting the
cable/boot off to access the spark plugs?

Thanks,
Devin Nelson
 
For best resaults use NGK plugs

Hi,
Twist it hard then pull the wire gently but with firm force.
Make sure the plug rotates when you twist meaning it is loose.
Then pull. And install Platinum or Iridium ones which last LONG,
LONG time.

Do not pull the spark plug wire, Grab the rubber boot near the valve cover a
twist 90 degrees back and forth and pull. It will come. I use standard NGK
plugs and at 30,000 miles they look to go another 30,000 but I don't. Use
silicon spray on the outside of the boot to ease removal next time. Eddie

When you finally get them off, apply a light coat of dielectric grease
around the inside sealing surface of each boot prior to reinstallation.
Helps seal out corrosion and aids the next plug swap.

Two reasons I pull and inspect spark plugs at ~ 30,000 miles. 1. I can see
how each cylinder is performing and 2. It assures me that my plugs will not
seize in the head as I have seen many times. Usually my standard NGKs look
like they would go to 60-80,00 but I don't. My Forester always seems to
perform better (no Data) after a plug and air filter change. Eddie
