Ignition Coil - Removal

3.7L





An ignition coil (2) with a spark plug wire (1) attached is used for two cylinders. The three coils fits into machined holes in the cylinder head for cylinders 1, 3, and 5. A mounting stud/nut secures each coil to the top of the intake manifold. The bottom of the coil assembly is equipped with a rubber boot (4) to seal the spark plug (5) to the coil. Inside each rubber boot is a spring. The spring is used for a mechanical contact between the coil and the top of spark plugs. These rubber boots and springs are a permanent part of the coil assembly and are not serviced separately. The rubber boot (4) is also used to seal the coil at the opening into the cylinder head
