Depending
on how nice the automobile engineers are, replacing spark plugs might
be a simple task—or not.Actually, numerous engineering considerations,
including how sleek you want your automobile to look, influence the
location and convenience of access to spark plugs.Sleek implies low, and
space must be found someplace.The engine compartment has been reduced
in size.
Vehicle Terminology
A spark plug is a metal-and-ceramic component that ignites the
fuel/air mixture in each cylinder of an engine using electricity.Six
spark plugs are used in a six-cylinder engine. Platinum plugs are
high-quality spark plugs with platinum tips that last significantly
longer than standard plug tips.
Why aren’t platinum plugs required in every vehicle?Ans.They’re not cheap.
Why
are some automobiles required to have them? Ans.It makes sense to
change the spark plugs less frequently because they are positioned in a
difficult-to-replace location.
So the first step in changing
spark plugs may be to locate them.There are, fortunately, warning
indications.A spark plug is required for each cylinder in your car’s
engine, and each spark plug requires a wire to connect it to it.
Begin
by locating a set of four, six, or eight wires in the engine
compartment (depending on the number of cylinders).After that, follow
each wire to a spark plug in the engine.
The technique for replacing spark plugs is as follows:
Allow your car’s engine to cool before removing the plugs.
It’s safer (you’ll be less likely to get burned), and it’ll make replacing spark plugs a lot easier.
Spray penetrating oil around the base of the clog and let it soak in if you’re having difficulties removing it.
Because
penetrating oil is combustible and can fire when heated, it should be
handled with caution. It can also damage neighboring electronic
components.
1. Use masking tape to mark the wires before
removing them from the plugs (so you can put them back on in the correct
order). Use any marking system that you know you’ll be able to figure
out later.
2. Carefully twist and pull the spark plug wire where it connects to
the plug (called the boot) until the boot comes off the plug tip. Make
sure you pull on the boot and not the wire or the two may separate.
3.
Use a shop rag and small paint brush to clean around the spark plug so
debris doesn’t fall into the engine when the plug is removed.
4. Use a spark plug wrench to remove the first plug from the engine.
5.
Using a wire feeler gauge, check and adjust the new spark plug gap
according to the manufacturer’s recommendation for that engine. The
owner’s manual or your parts supplier should have that info. (Note:
Always replace a spark plug with the same make and model unless advised
to otherwise by a competent auto parts clerk or mechanic.)
Lubricate
the threads of the spark plug with Never-Seez or a similar lubricant
(available from your parts supplier) to make the plugs easier to remove
the next time.
6. By hand, screw the new plug into the spark plug
hole until the plug comes in contact with the engine. Then use the
socket wrench to tighten the plug two-thirds of a turn. (If you have a
torque wrench, it’s preferred to tighten the plug to the torque value
recommended by the car’s manufacturer. However, the procedure described
here is adequate.)
7. Inspect the spark plug wire and boot for
damage, replacing as a unit if needed. Otherwise, place the boot on top
of the plug and press firmly.
8. Repeat this process to replace the other spark plugs.
Platinum plugs are high-quality spark plugs with platinum tips that last significantly longer than standard plug tips.
