SYSTEM TESTING See Figures 1, 2, 3 and 4 Fig. Fig. 1: Glow plug system schematic Fig. Fig. 2: Dropping resistor and glow plug relay locations Fig. Fig. 3: Thermo switch location Fig. Fig. 4: Dropping resistor check To test the dropping resistor, check for continuity across the terminals as described in the illustration. If no continuity exists, replace the unit. 1. To test the thermo switch, first remove the switch. Submerge the end of the switch in water and raise the temperature gradually. The switch should be off at 126-140°F (53-60°C) or lower. The switch should be on at 134-145°F (57-63°C) or higher. If not, replace the switch. 2. REMOVAL & INSTALLATION See Figure 5 Fig. Fig. 5: Location of the glow plugs The glow plugs are located under the injection nozzles, and are threaded into the cylinder head. Disconnect the negative (-) battery cable. 1. Disconnect the glow plug and unscrew it from the engine. 2. To install: Lubricate with anti-seize compound before installing the plug. 3. Install and tighten the plug to 65 ft. lbs. (88 Nm). 4. Reconnect the plug wiring. 5. Connect the battery cable and check operation. 6.

2008 Ford F-250/350/450 6.4L Powerstroke diesel aft-filter system Installation Manual

Installation instructions: 1.) Raise and support vehicle. 2.) Lubricate all factory rubber hangers and pipe slip-connectors with penetrating oil. 3.) Loosen clamp, attaching inlet of stock muffler to inlet pipe. 4.) Remove muffler/tailpipe assembly from inlet pipe and rubber hangers; remove from vehicle. Removal of muffler/tailpipe can be made easier by first cutting the tailpipe from the muffler with a reciprocating saw. 5.) Remove hanger rod on inlet pipe from rubber frame hanger. 6.) Loosen clamp attaching inlet pipe to outlet of converter and remove pipe from vehicle. 7.) Place supplied 3.5? clamp with hole over small end of supplied adapter and install onto outlet of converter. Engage slot in adapter with index bump on converter outlet and place hole in clamp over bump. Tighten clamp fully. 8.) Place one supplied 4? clamp over inlet pipe slip-connector and install pipe onto adapter. Insert hanger rod on pipe into corresponding rubber hanger on frame. 9.) Rotate inlet pipe as needed to orient end of hanger rod, which is inserted into rubber hanger, in a horizontal position and tighten clamp at slip-connector fully 10.) Place one supplied 4? clamp over muffler inlet and install muffler onto inlet pipe. 11.) Place one supplied 4? clamp over inlet of tailpipe section “A” and install pipe onto muffler and into corresponding factory rubber hangers just above muffler. 12.) Place one supplied 4? clamp over inlet of tailpipe section “B” and install pipe into rear-most rubber frame hanger and onto outlet of tailpipe section “A”. 13.) Place remaining 4? clamp over tip inlet and install tip onto outlet of tailpipe section “B”. 14.) Align all components for desired fit and tighten all clamps fully


DIAGNOSTIC SYSTEM CHECK – THEFT DETERRENT Test Description The number(s) below refer to the step number(s) on the diagnostic table. 2: Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit. The specified procedure will determine the particular condition. 5: The presence of DTCs which begin with “U” indicate some other module is not communicating. The specified procedure will compile all the available information before tests are performed. 6: The listed DTCs are internal module malfunctions and should be corrected before attempting any other diagnostics. 7: The listed DTCs are battery voltage related malfunctions and should be corrected before attempting any other diagnostics. Diagnostic System Check – Theft Deterrent Step Action Yes No 1 Install a scan tool. Does the scan tool power up? Go to Step 2 Go to Scan Tool Does Not Power Up in Data Link Communications 2 1. Turn ON the ignition, with the engine OFF. 2. Attempt to establish communication with the body control module (BCM) and the powertrain control module (PCM). Does the scan tool communicate with the specified modules? Go to Step 3 Go to Scan Tool Does Not Communicate with Class 2 Device in Data Link Communications 3 1. Access the Class 2 Power Mode parameter in the Diagnostic Circuit Check menu on the scan tool. IMPORTANT: Important: The engine may start during the following step. Turn OFF the engine as soon as you have observed the Crank power mode. IMPORTANT: Insure that all ignition switch positions are observed
