The International T 444E diesel is a four stroke V8 engine. It features overhead valves and is water-cooled and turbocharged. The engine is fueled by a direct injection fuel system with electronic sensors and Hydraulically actuated Electronically controlled Unit Injectors (HEUI). It has a displacement of 7.3 liters (444 cubic inches). When viewing the engine from the rear (flywheel end), the right hand bank of cylinders are numbered 1, 3, 5, and 7. Cylinder number 1 is at the front. The left bank consists of cylinders 2, 4, 6, and 8. In this case, cylinder number 2 is at the front. The engines numerical firing sequence is 1–2–7–3–4–5–6–8.How does this work?International T444e Engine Diagram

The Phoenix Module works on both the Navistar® DT466 and the T444E engines. Gains of up to 60HP are achievable. 1994 - 1997 International Navistar® Phoenix Module Installation InstructionsBefore proceeding any further, **REMOVE KEY FROM IGNITION AND DISCONNECT THE BATTERY**Locate the bulkhead cover on the driver's side of the firewall. Remove the two 11 mm bolts which hold the cover in place. Remove the cover and set aside.At this point you should see three connectors protruding through the firewall bulkhead, a square one, a round one and a rectangle one. The rectangle connector (seen here on the right) is the PCM connector. Locate the 10mm bolt which is directly in the center of the connector and unscrew to remove the connector from the PCM. Do not attempt to remove the bolt from the connector as it is permanently attached.The PCM Code that we will need in order to program your Phoenix Module will be located here.From inside the cab, begin removing the upper vent panel by removing the two screws that hold it down. With the vent panel removed, you now have access to remove the A-pillar panel. Pull the A-pillar cover out from the corner to unsnap the clips. Remove the 3 upper instrument cluster panel screws, 2 of which are located at the bottom of the A-pillar, and 1 located to the right of the instrument cluster.Remove the side dash panel screw as well as the 4 screws located around the instrument cluster. If the vehicle is equipped with power windows, there will be a wiring harness attached to the left side of the dash panel where the window buttons are located. Disconnect the harness connector and lay the dash panel aside.ONCE AGAIN, PLEASE ENSURE BATTERY IS DISCONNECTED BEFORE PROCEEDING! Remove both 13 mm bolts (11mm on some applications) that attach the fuse panel to the bottom of the dashboard. Push the fuse panel down and out of the way as necessary to allow for clearance. Remove the 4 screws that attach the kick panel to the body. The kick panel is easily identified by the round diagnostic connector attached to it.Remove the 4 screws attaching the side panel to the dash panel (1 at the top front, 2 on the bottom front, and 1 on the bottom underside). With the screws removed, pull forward on the front dash panel just enough to allow the side bracket to be twisted out from behind it. Once this is accomplished, pull the side panel down and away from the dash until it is clear.You should now have clear access to the PCM. Remove the #3 Phillips screw from the PCM mounting bracket.The PCM mounting bracket (seen here as the black bracket located at an angle and just to the right of the PCM) must be tilted up from the bottom to disengage the 'hook' at the top of the bracket. This will allow the bracket and the PCM to be removed. Be careful not to snag any wires when removing either the bracket or the PCM.With the PCM removed form the vehicle, you may now begin the process of cleaning the service connector. The best method is to remove the 5.5mm (7/32') bolts that hold the PCM together. There are 6 of them located on the front cover. This is how the PCM looks with the cover removed. Please note that you can easily see the 4-digit PCM Code that is located directly in the middle of the bar code sticker of the PCM. In this example, the PCM Code is TJM2.Now separate the back shell from the main part of the PCM. Be careful not to lose the little plastic board support.Many computers will have a coating of lithium (white) grease covering the connector. Remove the grease using a cloth or paper towel. There will also be a coating of clear silicone covering the connector.Use the provided Scotch-Brite® pad to clear away the silicone. Acetone (nail polish remover) helps to clean the connector. DO NOT USE aggressive solvents such as Laquer Thinner as this will damage the fiberglass resin of the circuit board.BOTH sides of the connector must be cleaned thoroughly. Failure to properly clean the connector may cause the vehicle not to start and also cause damage to the module and/or PCM. Any module or PCM that has been damaged due to improper installation WILL NOT be covered under warranty.Once the connector is thoroughly cleaned, temporarily attach the module to the PCM, attach the PCM to the harness and reconnect the battery. Attempt to start the vehicle. If vehicle does not start, turn ignition off, disconnect the battery, remove the PCM, and check the module and connector to ensure the there are no traces of silicone that would cause erratic operation. Before calling for technical support, be absolutely certain that ALL silicone is cleaned from both sides. 98% of No-Start conditions are the result of poorly cleaned connectors.If all tests pass satisfactorily, shut off the vehicle and remove the PCM from the harness. Fasten the module to the computer using duct or packing tape to help prevent the chip from coming loose due to vibration. Reassembly if the reverse of the disassembly. Due to the nature of the module, the PCM bracket will not return to its original location without modification. You may choose to trim the back end of the PCM bracket which will uncover the service port on the back of the ECM. If you cannot trim the bracket, then you may leave the bracket off. However, a suitable fastening method (such as Velcro) is recommended to prevent the PCM from rattling against the kick panel while driving. Navistar® T444e Navistar® DT466
