Download The Ford Triton Spark plug holes have been divided into three Types for model years 1993 through 2005. The drawings below will help you identify each Type. Each individual cylinder head will have the same Type for all spark plug holes. Type 1 Type 2 Type 3 Cleaning: 1. Remove spark plug from a good spark plug hole, chuck the FT5FTCB brush supplied in the kit into a slow speed drill, and clean the bottom of the hole. Note: If procedure is being done in vehicle clean hole using a vacuum cleaner to remove debris. Caution: Do not use the brush to clean the hole after the repair insert has been installed. Identifying: Perform Steps 2 through 4 to determine cylinder head Type: 2. Gauge the spark plug hole using FT5CG Tooling Type Gauge; this is to be used as a comparison when gauging the defective spark plug hole in step number 4. Pull down on the gauge until the snap ring seats against the top of the probe.
