Advance Adapters 713093 - Manual (Page 5)

Throttle Linkage:
1999 to 2002 truck Vortec engines are cable operated, to connect the two,
start by drilling a hole in the firewall where the stock Jeep cable was lo-
cated. The hole diameter is determined by taking a pair of calipers and
measuring the mounting slot on the stock GM throttle linkage. Use the
correct drill bit and open the stock hole on the Jeep firewall. The hole must
be big enough to accept the housing, but not too large for it to slip through.
The inner cable may need some shortening to work correctly with the
stock pedal. It may even be necessary to solder and relocate the stop on
the cable.
Fans:
Either a stock clutch fan or an electric fan will work with these motor mounts. With our aluminum radiator, there should
be approximately 2-1/2” between the clutch on the fan and the radiator fins. A
custom shroud will have to be fabricated if you use the clutch fan.
An electric fan is what we used and it works great with these mounts. There
is ample clearance in the engine compartment which allows for good air circu-
lation. We offer a Spal fan and mounting brackets to fit our radiator under Part
No. 716670. This fan is rated at 2070 CFM. Not all fans are created equal, so
make sure that your electric fan has enough CFM for your setup. Also keep in
mind that a “puller” fan will draw in more air and cools better than a “pusher”
fan.
Exhaust:
All of the stock exhaust system must be removed for the Vortec conversion. New pipe should be run from the manifolds
all the way out. Routing the exhaust around the frame should not be a problem. Weld flanges and crush gaskets are
available separately for the truck-style Vortec manifolds (AA P/N 716573 and P/N 717514). If you are doing a smog legal
conversion, you may need to find a stock GM vehicle to measure the location of where the oxygen sensors and cats are
located on the stock pipes. Also make sure proper heat shielding is used between exhaust components and the floor-
board. The recommended size for exhaust is 2-1/2” primaries into 3” tail pipe, or 2-1/2” dual all the way out. For
pollution controlled vehicles, please refer to the owner’s manual for the stock exhaust
configuration. We do not offer any header systems for the Jeep TJ.
Intake:
The intake we used on our TJ installation was a GM 25176891. This ducting was cut
and modified to fit the Jeep configuration. We used a K&N air filter, P/N E-1796. This
setup required a electric fan to be used.
