How do i change the spark plugs and is it easy

• With engine running listen for a whistle indicating a vacuum hose leak. It is easy for a vacuum hose to pull loose while removing replacing plugs.

• Check for spark-plug leads . You can check at night and look for spark.

• Remove and check each spark plug. The ceramic tops are easy to crack.
• Check the spark gap, hitting or picking up residue on the tip is common.

See my tips section for instructions on how to replace the spark plugs.

I own a 2004 jeep Grand Cherokee 4.7 V-8 It took me 3 1/2 hours to complete changing the spark plugs. First one must remove the cover from the air filter and to the carbuetor there are two bolts on each side of the cover over the engine then the driver side is easy to remove the boots on each plug the passenger side is pretty easy except for the last plug all the way on the back this one took me 1/2 to remove because there is lots of obstructions like the power steering line and the oil line and electrical cables.

They are on the heads, follow the plug wires.

ok that is not the easy the ones in the front those are the easy ones but the ones in the back thse are dificul ones so in order to change those spark plug you need to race the car and try to change them from underneath this is one way the other way is to remove the intake sistem and change them from the top
