MPORTANT: Due to the number of applications and years that the LT-1 Cap and Rotor are used

on, it is highly recommended to have the Service Manual for your vehicle during this

installation.

DISASSEMBLY

1. Disconnect the negative battery cable.

2. Locate the radiator petcock and drain the coolant from the system.

3. Disconnect the MAF and IAC sensors. Remove the air intake ductwork and the MAF sensor.

4. Once the coolant is drained, remove the upper radiator hose from the thermostat housing.

5. Loosen the three bolts that secure the crankshaft pulley/hub assembly. Do not remove them

entirely at this time.

6. Remove the accessory drive belt by moving the spring loaded idler pulley. Use caution as this

pulley is spring loaded! The belt will slide off the pulley system and the idler pulley will settle

beyond its installed position.

7. Once the belt is removed, proceed with removing the pulley from the crankshaft hub by pulling

the three retaining bolts.

8. It may be necessary to remove the cooling fan. This is done by removing the four bolts and

disconnecting the wiring connection.

9. Disconnect the air pump power wires and remove the

air pump from its mounting brackets.

10. Disconnect the coolant temperature wiring sensor

located on the water pump.

11. Loosen the lower radiator hose clamp and the two heater

hose clamps at the water pump. Coolant will generally

still pour out of the hoses and water pump.

12. To remove the water pump, the power steering pump

may need to be removed. With a shorter extension, the

water pump bolt should be able to be accessed. There

are six water pump bolts. Once again, more coolant may

spill out.

13. At this point, you should be able to access the distributor

cap! Mark the location of each spark plug wire before

removing them.

14. Remove the vacuum lines (if equipped) and the distributor
