Installation Instructions

Vortech Maxflow

Power Cooler

Congratulations on selecting the best performing and most

efficient aftercooler today... the Vortech Maxflow Power Cooler !

The Vortech Maxflow Power Cooler system was designed as a street/strip oriented aftercooler,

specifically for use on 1993 - 1997 LT1 GM F-Body vehicles equipped with a Vortech Supercharger

producing up to approximately 580 HP. The Maxflow Power Cooler system will fit and work equally

well with other brands of centrifugal superchargers as well as turbochargers, with minor modifications.

As with any power enhancing product, this system is intended for use on healthy, well-maintained

engines. Vortech Engineering 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 a note of the following key points:

1. Use only premium grade fuel 92 octane or higher (R+M/2).

2. Always listen for any sign of detonation (pinging) and discontinue hard use (no boost) until

problem is resolved.

3. Water Cooler Mounting

To properly mount the cooler in the limited space

available, it is necessary to cut two 1-1/2” holes

into the inside of the lower front bumper fascia.

This will accomplish a clean secure hose route with

a minimum of bends and restrictions.

A. Remove the three plastic (push-in) fascia

retainers that are used to attach the rear of the

lower front bumper fascia to the vehicle.

B. Loosely attach the supplied water cooler

brackets to the cooler using the supplied 1/4”

hardware. Following the photos, center the

cooler on the front of the vehicle. Using the

mounted cooler brackets as a guide, mark the

position on the lower radiator core support

where the bracket mounting holes must be

drilled (see photo - 3). Drill the four mounting

holes and loosely attach the cooler assembly

to the core support. With the cooler in place,

mark the back of the front lower bumper cover

location where the 1-1/2” holes are to be bored.

C. Remove the cooler from the vehicle and bore

the two 1-1/2” holes where previously marked

in the front fascia.

D. Using pipe sealant, thread both of the 3/4”

x 1/2” NPT x 90° fittings into the water cooler.

Both fittings should be clocked to point toward

the side, parallel to the cooler face.

E. Install the fittings (that are attached to the

cooler) through the 1-1/2" holes previously

bored into the fascia. Make sure that the cooler

is configured so that the 90° fittings are on the

top and pointed toward the driver side of the

vehicle. Following the Hose/Component

Schematic, cut and attach the two lengths (90"

& 34") of 3/4" hose to the fittings on the water

cooler. Install one nylon clamp on each of the

hoses where it slides onto the cooler fitting by

pulling down the fascia and reaching in behind

it. Attach the bottom portion of the cooler to

the radiator core support using the previously

drilled holes and supplied brackets (see photo

- 4). Secure all fasteners.

F. Reinstall the three plastic fascia retainers.

(continued)

31JAN00 V 1.0

4. Water Tank Mounting

A. Install all of the fittings, hoses and tank tabs

onto the tank exactly as shown in photo - 5.

Orient the hoses to match the hoses in the

photo and use the supplied #20 and #10 hose

clamps to secure the hoses to the tank. Insert

one of the supplied 3/4” hose barb unions into

the open end of the 3/4” x 90° hose. Make

sure that both hoses each have their shorter

“leg” attached to the tank fittings (the longer

end of each hose should be pointing up and

away from the tank). Attach the tabs to the

tank using the supplied1/4-20 x 1/2” bolts and

washers, do not overtighten.

B. From underneath the vehicle, locate the tank

into the upper corner of the driver’s side lower

wheel housing (see photo - 6). Start by routing

the two tank hoses through the opening

connecting the lower wheel housing to the

main engine compartment (rotating the

tank/hose assembly while installing makes

hose routing easier). With the tank being held

in position, mark and drill two mounting holes.

One will be made in the plastic inner fenderwell

and use the supplied nut, bolt and washers.

The second will be into the metal above the

tank using the supplied #12 sheetmetal screw

and washer.

C. Attach the 3/4" hose running from the driver

side water cooler fitting to the outlet on the

water pump and secure with nylon clamps.

Trim hose length if necessary to maintain a

smooth hose routing.

D. Following Hose/Component Schematic, attach

a 3/4" 90° elbow to the inlet of the water pump.

Attach another 3/4" 90° elbow to the bottom

of the water tank (be sure to install the short

leg of the 3/4" 90° hoses onto each component).

Connect this elbow to the previously installed

hose on the water pump using a hose union.

Secure ends with nylon clamps.

4. Water Tank Mounting

E. The open (top) end of the 1-1/4” filler hose

will need to be trimmed 2-1/2” shorter so that

when the hose adapter and cap are installed,

the cap is near level with the top of the radiator

core support. Insert the supplied aluminum

hose adapter into the open end of the long 1-

1/4” tank filler hose (this hose should have

been previously routed up into the engine com-

partment) and secure with the supplied #20

clamp. If necessary, slightly rotate the filler

hose assembly so that the aluminum hose

adapter is up against the rear of the upper core

support (see photo - 7). Secure the assembly

to the radiator core support using the supplied

adel clamp and sheetmetal screw.

6. Aftercooler Core

A. Wrap the aftercooler core with the supplied

heat blanket. Install the two supplied 1/2” NPT

x 3/4” straight barb fittings into the aftercooler

core using a small amount of pipe sealant onto

the threads.

B. Attach the supplied 90° long rubber elbows to

the water fittings (the short leg of each elbow

must be trimmed 1-1/4" and be installed with

the short leg on the core side) on the core.

Slide a hose union into the open ends of each

elbow (see photo - 9). Connect the previously

cut 48" and 90" sections of hose to the proper

hose unions (refer to the Hose/Component

Schematic). Secure all hose connections with

the supplied nylon clamps.

C. Remove the two center driver’s side valve cover

bolts temporarily. Place the supplied aftercooler

core support onto the center of the valve cover

and secure with the factory valve cover bolts

(see photo - 10).

D. Place the aftercooler core (snaps down) onto

the aftercooler core support, in-between the

power brake booster and the intake manifold

(see photo - 11), while at the same time routing

the water lines around the rear of the power

brake booster toward the driver side corner of

the engine compartment. It may be necessary

to lightly bend the brake line cluster on the

shock tower for core clearance. Also, the

factory fuel lines must be routed down along

the side of the valve cover. Make sure that the

routing of the water lines allows for a smooth,

non-kinked path.

E. Route the water hose coming from the driver

side fitting on the core, to the previously

mounted 3/4” x 90° rubber hose on top of the

water tank (there should already be a brass

hose union attached here). Connect the hose

to the tank at this point. Trim hose length if

necessary. Do not yet secure with the supplied

plastic clamp; the hose must be removed in

pipe thread end pointing toward the front of

the vehicle).

D. Following the Air Injection Modification diagram,

cut a 2” length from the 5/8” end of the supplied

180° rubber adapter. Place the short length of

hose onto the discharge side of the factory air

pump. Into this short hose, insert the supplied

5/8” tee with the leg pointing up. Slide the 5/8”

end of the180° rubber hose onto the horizontal

run of the tee. Attach the 90° end of the supplied

5/8” x 90° x 48” rubber hose onto the leg

(pointing up) of the plastic tee and route the

straight end in between the front of the core and

the exhaust air injection location (see photo -

connect the new 5/8” hose to the existing hose

running to the passenger side exhaust manifold.

Trim hose length to fit.

E. Using the supplied 2-3/4” sleeves and #44

hose clamps, connect the 2-3/4” tube to the

discharge of the supercharger and the

aftercooler core inlet. Leave the clamps loose

temporarily.

F. Remove 1” from the round end of the original

Vortech aluminum throttle body elbow and re-

install onto the throttle body using the original

clamps and sleeves. See Aluminum Discharge

Tube Modification diagram.

G. Install the remaining supplied heat sleeve/blanket

onto the supplied 3” discharge tube. Using the

supplied reducers and hose clamps, secure the

tube to the aftercooler and the modified throttle

body inlet elbow. Attach the existing super-

charger bypass valve and supplied 1” x 4” hose

valve onto the supplied 90° compression fitting.

J. Slide the factory air pump check valve (if

equipped) into the 3/4” end of the 180° elbow

previously installed onto the factory air pump.

If the vehicle is not equipped with a check valve

(earlier models), insert the supplied 3/4” hose

barb union into the hose. From the check valve

(or barb union), use the supplied 3/4” x 6”

length of hose to join the diverter valve and air

pump together.

K. Reattach the brake booster vacuum hose to

the booster by routing it up over the top of the

aftercooler core. Trim hose length if necessary.

31JAN00 V 1.0

8. Final Check

A. Reconnect the battery cable.

B. Temporarily remove the aftercooler return hose

from the 3/4” union running to the water tank

(see step 6E).

C. Fill the Vortech water tank with a 25%/75%

coolant/water mix until water starts to run out

of the rubber return elbow located on the water

tank. Temporarily insert the open end of the

return hose (running from the aftercooler core)

into the tank filler neck.

D. Turn the ignition key to the “on” position to

prime the water pump. Water should be flowing

through the system. If water is not flowing,

air must be purged from the lines by applying

suction to the end of the return hose inserted

in the filler neck. The pump should not be

allowed to run for extended periods (30 seconds

or more) without waterflow. Once water is

flowing, allow to run for approximately one

minute. Turn off the ignition and wait for one

more minute. Restart the pump and make sure

that the water is still flowing properly.

Reconnect the core return hose to the 3/4”

barb union on the tank and secure with a clamp.

E. Check all fittings, lines and hoses for routing

and leaks (away from hot objects and sharp

edges).

F. Reinstall the mass air meter, air filter assembly,

lower splashguard and radiator deflector.

G. With the pump running and flowing water

through the system, fill the water tank up. (Do

not overfill the tank. Stop filling when the water

has come up to the base of the filler hose.)

Attach the filler cap to the aluminum filler hose

adapter. Drill a 1/4” hole (if not already done

by Vortech) in the center of the fill cap to

provide the system with a vent to allow for

thermal expansion of the water and air.
