IMPORTANT NOTES

T

his kit requires ECM programming. The hand-held ECM programmer is
not included in the kit box and must be ordered directly from Paxton by

the installing customer (the charge for this unit has been included in the
purchase price).
Included in this kit is a credit tag for one hand-held programmer. The program­mers are made specifically for each individual vehicle with respect to the facto­ry ECM calibration and VIN. Simply follow the instructions on the hand-held
programmer credit tag.
Your ECM hand-held programmer comes with a twelve month limited warranty
from the original date of purchase of your supercharger system (see the
Owner’s Manual for details).

2004 Models

- Vehicles equipped with on-star that have aftermarket stereos
will experience problems with the ability to re-program the
vehicle’s ECM. It is necessary to disconnect the aftermarket
stereo from the factory wiring harness before continuing with
the programming procedure.

Paxton Automotive is not responsible for engine or ECM damage due to an
improperly installed/mishandled ECM module or ECM.

efore beginning this installation, please
read through this entire instruction book-

let and the Street Supercharger System
Owner's Manual which includes the Automotive
Limited Warranties Program and the Warranty
Registration form.

Paxton supercharger systems are performance
improving devices. In most cases, increases in
torque of 30-35% and horsepower of 35-45% can
be expected with the boost levels specified by

Paxton Automotive. This product is intended for
use on healthy, well maintained engines.

Installation on a worn-out or damaged engine is
not recommended and may result in failure of the
engine as well as the supercharger. Paxton
Automotive is not responsible for engine damage.

Installation on new vehicles will not harm or
adversely affect the break-in period so long as fac­tory break-in procedures are followed.

For best performance and continued durability,
please take note of the following key points:

1. Use only premium grade fuel 91 octane or

higher (R+M/2).

2. The engine must have stock compression

ratio.

3. If the engine has been modified in any way,

check with Paxton prior to using this prod­uct.

4. Always listen for any sign of detonation

(pinging) and discontinue hard use (no boost)
until problem is resolved.

5. Perform an oil and filter change upon com-

pletion of this installation and prior to test
driving your vehicle. Thereafter, always use a
high grade SF rated engine oil or a high qual­ity synthetic, and change the oil and filter
every 3,000 miles or less. Never attempt to

extend the oil change interval beyond
3,000 miles, regardless of oil manufactur­er's claims as potential damage to the
supercharger may result.

6. Before beginning installation, replace all

spark plugs that are older than 1 year or
10,000 miles with original heat range plugs
as specified by the manufacturer and reset
timing to factory specifications (follow the
procedures indicated within the factory repair
manual and/or as indicated on the factory
underhood emissions tag). Do not use plat-

inum spark plugs unless they are original
equipment. Change spark plugs at least

every 15,000 miles and spark plug wires at
least every 50,000 miles.

Section 1

COMPONENT REMOVAL

A. Escalade/Denali: Drain a sufficient

amount of coolant to allow for removal of
the upper radiator hose and clamps.

B. Escalade/Denali: Disconnect the negative

battery cable.
H2 Hummer: Disconnect the positive and
negative battery cables and remove the
battery from the vehicle.

C. H2 Hummer: Remove the screws securing

the battery tray, then remove the tray from
the vehicle.

D. Remove all ducting between the MAF

meter and the throttle body.

E. Remove the upper fan shroud.

Escalade/Denali: Remove the radiator
hose.

F. Remove the accessory drive belt. (Keep in

the vehicle as a spare.)

G. Remove the two bolts securing the alterna-

tor fusible link junction box and set aside.

H. Remove the idler from the cast bracket and

set aside for later use.

I. The plastic engine covers that extend over

the valve covers will need to be removed.
The upper manifold cover section may
either be removed completely or left in
place and trimmed in order to clear super­charger componentry.

J. Remove the power steering pump pulley

with a pulley puller. Remove the three
bolts securing the front of the power steer­ing pump. Loosen the bolt securing the
back of the pump to the engine block.

K. Remove the alternator, bushings and bolts

and set aside for later use. The alternator
bushings can be removed by tapping the
small end through the bracket with an
appropriately sized socket.

L. Remove the alternator and power steering

pump mounting bracket by removing the
three bolts securing it to the head and the
bottom bolt securing it to the engine block.

M. Remove the valve cover breather hose

from the passenger’s side of the throttle
body and cap off the throttle body nipple
with supplied 3/8" vacuum cap.

N. Remove the oil filler neck and cap from

the passenger’s side valve cover. Do this
by twisting in a counter-clockwise motion.
Reinstall the cap directly into the valve
cover.

O. Escalade/Denali/'03 H2 Hummer: Locate

the breather hose on the rear of the driver’s
side valve cover. Pull the hose and stock
PCV valve from the rubber grommet in the
valve cover. Remove the stock PCV valve
from the breather hose and install the sup­plied PCV valve in its place. Reinstall the
new PCV valve with the hose attached to it
into the rubber grommet in the valve
cover.
