How to do a spark plug change on a 2003 Jeep Liberty
how to move hands, ?
im i to guess this is your first spark plug pull even on a lawn-mower?
what engine do you have, 90% posts lack what engine it is on a engine question, and we are still guessing, and nuttn happens.
lets see.you pull HV wires 1 by 1, and replace them using a spark plug socket wrench.
if the engine has COP coils, those come off, first, (do tell got cops)>?
do not mix up the spark wires or it will not run.
why not watch youtube of 10000 doing this on all engines. to get a fell of the ways and means.... simple huh?
only start a spark plug by hand , never use a wrench.
do not over tighten them (rule 2)
2.4L engine, 4 cylinder??????
this is my guess.
ill look that up for you.
ok i looked, the 2.4L uses coil pack
so rule 1 applies, DO NOT MIX the HV wires on the COIL PACK>
remove the spark plug wire from ONE spark plug]
remove the spark plug (turns counter clock wise)
put in new plug (right part number and gap it to spec.
torque it to spec, and put back the wire.
move to next plug wire and repeat.
HV means those high voltage spark wires, that make you glow like a June bug if you get HIT. the 50,000 volt wires.
RE14MCC5 (Champion #) plugs
48 thou gap
but the hood sticker wins this ... not me.... read it.
the 3.7 has 6 cop coils , no signal coil pack.
my 3.8L has coil packs.
so as you can see , each engine is unique, by year and car.
