Tip

Changing spark plugs in 95 and up blazers.


If you own a blazer from 95 or up, which is the newer body style, you will find when you go to change the spark plugs, you will not be able to reach one pesky plug that is blocked by the steering column.

Here is how to get it out.

  1. take a socket that fits only over the porcelain closely and a wrench that has a closed end side that will slide over the socket out side.
  2. Put the socket over the plug end, and using the wrench, put the closed end over it and use it for leverage to break the porcelain off.
Now you will be able to fit a regular size socket over the plug to remove it.

When you go to put the new one in, put it in and hand tighten as much as you can, then us an open ended wrench to tighten it.

Mazda spark plug gap and torque


No it is not critical, you can use torque wrench to fit spark plugs. Different spark plugs require different amount of torque.

How do you replace oil sending unit on 1989 chevy corsica 2.8


Buy the replacement part first and whatever tool size fits is going to be apparent.
The oil pressure.temp. sensor looks like a spark plug (kind of) . one wrench... whatever size...
DO NOT overtighten the replacement... it is a tapered threaded sensor ... and will damage the block if overtightened.

How to change spark plug on lexuse gs300 2003


Hi, You need a new Spark Plugs Spark Plug Wrench Socket wrench Extension (At least 2-3 inch) size 10 socket size 12 socket...
First thing you need to do is find out where the spark plug cover is. Once you figure that out there will probably be size 10 or/and 12 bolts honding it down. Take that off and there you will see sensors connecting to each other and holding the spark plug in the cylinders. Unplug all the sensors and pull out the circular plugs holding the spark plugs down. THey might be a little tight and hard to get out so you're going to need to give it a good tug. Once you pull them out MAKE SURE YOU DONT DROP ANYTHING INTO THE CYLINDERS. You can look down into them and see the spark plugs. Get your spark plug wrench, extension, and socket wrench and stick them down in and push so that the spark plug wrench grabs them. Just simply unscrew the plugs, pull them all out, and then put the next ones in, and tighten them down. Just connect all the sensors, and put the cover back on and you're done. Pretty simple.
Take care

Hi, My son was recently given a 1986 Eldorado. If


I can't find any mention of a special tool for spark plugs in my Chilton manual for that year and they are usually pretty good at letting you know. There are 2 different sizes of plug wrench's and maybe that is what they are talking about. When you order the new plugs have a look at them before you leave and see if your wrench fits. Hope this helps.

How to change spark plugs... 2003 ES300


Hi!

You need New Spark Plugs, Spark Plug Wrench Socket and Wrench Extension (at least 2-3 inch) size 10 socket and/or size 12 socket.
First of all, please check where the spark plug cover is. Once you figure that out there will probably be size 10 or/and 12 bolts holding it down. Take that off and there you will see sensors connecting to each other and holding the spark plug in the cylinders. Unplug all the sensors and pull out the circular plugs holding the spark plugs down. Pull them out and make sure that you don't drop anything into the cylinderes. You can look down into them and see the spark plugs. Get your spark plug wrench, extension, and socket wrench and stick them down in and push so that the spark plug wrench grabs them. Then unscrew the plugs, pull them out and put the next ones in and tighten them down. Just connect all the sensors, and put the cover back on.

Thanks for using FixYa and do rate if found this solution helpful.

Thanks
