FINAL INSPECTION
1. Check all lines (hydraulic, vacuum, air conditioning and
fuel) to ensure there is adequate clearance to headers.
2. Re-connect battery.
3. At this point, it is a good idea to look everything over and
make sure that nothing was missed in assembly.
4. Start vehicle and bring up to normal operating
temperature. Check for possible leaks.
5. Turn engine off and let cool. Tighten all bolts again.
