How many spark plugs does my engine have?
A four-cylinder car will have four spark plugs; a six-cylinder car will have six and so on (though a HEMI engine has two plugs per cylinder).
Where are the spark plugs in a V6?
You will need to count the number of spark plug wires (or high-tension wires) connected to the engine. The spark plug wires are located either on top of the engine cover (for cars with an inline six-cylinder engine) or on the sides of the engine (if you have a V6 engine).
How many ignition coils does a 6 cylinder engine have?
Modern cars usually have one ignition coil for every spark plug. So, if you have a six-cylinder engine, there is a strong possibility you have six coils.
Is it OK to drive with a bad ignition coil?
It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine. You’ll also learn how to diagnose and replace your faulty coil.
How long can I drive with a bad coil?
“How long should I drive my car with one bad coil pack?” The answer to that is about a week or less. Why? When runnig with a bad coil pack, that will inhibit the spark in that once cylinder, and the gasses, unburnt will flow through the exhust and potentilly gum up the catalytic converter.
How often should you replace ignition coils?
around 100,000 miles
Is it OK to change half the spark plugs?
Registered. I wouldn’t expect any real damage, but there is a very high likelihood that he will continue having ignition trouble. It is very likely that all 6 plugs are in equally bad condition, so replacing only half is sort of pointless.
What can cause ignition coil failure?
Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.
Can an ignition coil overheat?
Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat. An ignition coil will get warm in use but it should not burn you or be too hot to touch.
