COIL, Ignition: 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

1. Depending on which coil is being removed, the throttle body air intake tube or intake box may need to be removed to gain access to coil.
2. Disconnect electrical connector from coil by pushing downward on release lock on top of connector and pull connector from coil.
3. Clean area at base of coil with compressed air before removal.
