PerTronix JBA Exhaust 1619S-4 - Manual (Page 3)

INSTALLATION INSTRUCTIONS:
1. Place vehicle in a location where the floor is solid and flat, with adequate lighting. Do not attempt to work on
a hot engine. Heat causes metal to expand and makes removal of fasteners difficult at best. Disconnect the nega-
tive battery cable from the battery. Raise the front of the vehicle to obtain adequate access to the bottom exhaust
manifold flanges. Use large-basejack stands to support the vehicle. Do not rely on the jack! Block the tires to
prevent the vehicle from rolling off the jackstands.
2. Apply penetrating oil on all accessible fasteners and fittings before attempting to remove them.
3. From underneath the vehicle, loosen the bolts connecting the exhaust system to the exhaust manifolds. Move
the exhaust system back about 1/2 ”to gain work space.
4. On air injected models (P/N 1619), from above, loosen the air tubes at the outside of both driver and passen-
ger side manifolds.
5. Remove the Oil Dipstick. It has a separate mounting bolt on the head and uses an O-ring seal at the bottom.
6. On the driver’s side, remove the fasteners attaching the manifold to the head and remove the manifold.
7. On the passenger side, remove the fasteners attaching the manifold to the head then remove the manifold.
8. Remove the gaskets and any gasket material or any carbon deposits that remain on the head surface. The use
of a gasket removal agent will ease the removal of any gasket material. Use care not to get debris into ports or
spark plug holes.
Driver’s Side Header
1. Start the air injection tube nut on the driver’s side header before you start the header bolts.
2. Slip the dipstick through the driver’s side header and into the block before bolting the header to the head.
3. Slip the Header Gasket between the header and the head and install using the supplied header bolts and lock
washers. Apply Anti Sieze to the bolts before installing ans torue evenly to 13 ft./lb.
Passenger Side Header
1. Start the EGR tube and the Air Injection Tube on the passenger side header before you start the header bolts.
2. Slip the Header Gasket between the header and the head and install using the supplied headers bolts and lock
washers. Apply Anti Sieze to the bolts before installing ans torue evenly to 13 ft./lb.
3. Apply a light coating od Sensor Safe Hi Temp Silicone on the Header collector domes and connect the ex-
haust system to the new headers using the hardware provided.
4. Check that all bolts are tight. Make sure that all wiring, fuel lines, transmissions lines, brake lines etc are
clear of the headers and the exhaust and relocate as necessary.
5. Reconnect the negative battery cable.
6. Start the engine, check for leaks and test drive. Then let engine cool and then re-torque the header bolts.
7. Periodically check and retighten the header bolts.
