  32. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  33. Attach the two fans to the heat exchanger using the 8 supplied washers and button head bolts with a 1/8” allen wrench, locating the wire leads towards the bottom.
  34. Using a ½” wrench, attach the stock pump in the same orientation as stock to the AFCO heat exchanger using the supplied nuts.
  35. Connect the supplied 90o rubber hose between the pump outlet (facing down) and the heat exchanger inlet (30o tube). Trimming of the hose may be required. Clamp both ends with the supplied hose clamps.
  36. Snap the four supplied mounting grommets, washer side toward rear of vehicle, into the mounting holes on the heat exchanger brackets.
  37. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  38. Slide one of the supplied aluminum bushings into each blue grommet.
  39. Slide the heat exchanger up from the bottom and place on the mounting studs.
  40. If the pump outlet or hose is too close to the AC condenser or grille, rotate the pump in its rubber hanger until sufficient clearance is obtained. Lubrication of the rubber piece may be required in order to rotate or move the pump.
  41. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  42. Finish threading the bolts installed in step 22 completely into the bumper and tighten. Make sure that the washers do not get caught on the lip inside of the bumper and that they are resting flat.
  43. Secure the heat exchanger using the four supplied Nylock nuts. The blue grommets should crush approximately 1/16”. Do not over tighten the nuts.
  44. Install the plastic shroud on the outside of the AFCO brackets using the four factory clips.
  45. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  46. Re-attach the factory hoses to the lower heat exchanger outlet and the pump inlet using the factory clamps.
  47. Remove the cover from the fuse panel and unbolt the power lead shown below.
  48. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  49. Place the red wire from the fan harness on top of the power lead previously removed and bolt back into place. Remove the bolt next to the fuse box and mount the relay as shown.
  50. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  51. Mount the in-line fuse to the strut tower using the preexisting bolt. The cover should be reinstalled onto the fuse panel
  52. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  53. Run the wiring harness along the engine side of the fuse box up to the passenger side of the radiator. The harness will then go through the radiator support by the horns.
  54. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  55. The ground cables should be connected to the bolt on the front support, which is shown below. The weatherpack connectors can be connected to the fans at this point.
  56. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  57. Remove the plastic loom on the coolant pump harness and locate the white wire. This wire will have battery voltage when the pump is activated. Cut this wire approximately 2” from the pump connector.
  58. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  59. Insert the two ends of the wire cut in the previous step into the blue/clear 3M Scotchlock 3- way splice connector supplied. Note: It is not necessary to strip the wires, and the order of the wires inserted does not matter. Once the button is depressed, the connector is difficult to reuse, so be sure the wires are inserted completely. Insert the orange wire from the fan harness into the remaining hole. Using slip joint pliers, (or similar tool) press the blue button down into the connector until the button locks. The connector is filled with EG-3 sealant. Just wipe off any excess with a rag. You may wrap the connection with electrical tape, although it is not necessary.
  60. afco-pro-series-heat-exchanger-w-fans-07-12-gt500

  62. Verify all bolts, nuts, and hose connections.
  63. Fill the system and surge tank using the recommended OEM coolant.
  64. Reconnect the negative battery cable, start the vehicle, and allow the car to idle until warm. The heat exchanger pump will not turn on until the air charge is warm.
  65. Once the pump turns on, the level in the surge tank will drop rapidly. Continue adding coolant until at the recommended level. This system will hold approximately 1.5 gallons of coolant.
  66. Continue to run the vehicle for 5 minutes to verify all air is purged from the system. Check system for leaks while waiting.
  67. Once system is checked, install the bumper, splashguards, air dam, and wheels in the reverse of removal.

  28. Remove the pump from the factory bracket and remove any hoses connected to it.
  29. It is now recommended that the intake be removed to allow access to remove the hose that runs from the surge tank to the pump. Remove the one bolt holding the air filter housing, the band clamp holding the intake at the throttle body, and unplug the 2 sensors in the intake. Now remove the hose from the surge tank. The nylon sheath that protects the hose should be removed from the hose. This nylon sheath should be placed over the supplied hose, and the hose should be routed the same as factory. Attach using the supplied hose clamps.
