Before beginning this installation, please read through this entire instruction booklet 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. IMPORTANT NOTE: The standard water tank/filler system is not designed for use with ice. If an ice bath type of system is desired (drag racing) Vortech can supply a tank (#8N105-010) specifically designed for this type of use that mounts in the factory battery location (the battery must be relocated to the trunk). Part #8N105-010 is a larger capacity tank with a generous opening that allows for ice fill-up. A drain petcock is located on the side of the tank for removal of melted ice in between rounds during racing applications.

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. Photo - 3 C. Remove the cooler from the vehicle and bore the two 1-1/2” holes where previously marked in the front fascia. Photo - 4 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. 1-1/2” holes in front fascia 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.

All Rights Reserved, Intl. Copr. Secured 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. Photo - 5 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. Photo - 6 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. Water tank mounted in position 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. 5 © 2000 Vortech Engineering, Inc. All Rights Reserved, Intl. Copr. Secured 31JAN00 V 1.0 4. Water Tank Mounting (continued) 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 11/4” tank filler hose (this hose should have been previously routed up into the engine compartment) 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.

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. Photo - 9 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. Photo - 10 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 Photo - 11 Routed aftercooler water lines 8 © 2000 Vortech Engineering, Inc. All Rights Reserved, Intl. Copr.

Using a small amount of pipe thread sealant, thread the female end of the factory diverter 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. 12 © 2000 Vortech Engineering, Inc. All Rights Reserved, Intl. Copr. Secured 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. Final Check 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. 13 © 2000 Vortech Engineering, Inc.
