Common causes of camshaft timing belt failure on the above vehicles are due to incorrect operating tension, or ingress of dirt, water, or debris entering the timing belt cover. Predominantly on Fiesta models a high percentage of camshaft timing belt failures occur after the ancillary poly ‘V’ drive belt has failed, where strands of material off the broken belt have entered the timing belt cover. This is especially so where an ancillary belt has been fitted that does not contain “Kevlar” based materials. It is therefore important to always remove the timing belt cover to check for belt debris if the ancillary belt has failed. Any contamination that enters the timing belt cover can become compressed between the surfaces of the camshaft timing belt and drive pulleys. This causes wear to both the belt teeth, backing surface, and damage to the drive pulleys, resulting in premature failure of the camshaft timing belt. Later engines have modifications to improve the sealing of the belt cover around the crankshaft pulley, to reduce the level of outside contamination. Incorrect tensioning of the belt during installation will adversely affect the life of the belt. Before fitting a new belt it is important to check and observe the following points :- 1) Right Hand Inner Wing Splash Shield (Fiesta, Escort, Mondeo) This must be fitted and undamaged. 2) Timing Belt Cover Check that all components of the cover are fitted and undamaged. Ensure the latest type of modified cover is fitted. 3) a) Toothed Drive Pulleys Check that the tooth profiles are not worn or damaged. On vehicles built before January 1994 special attention should be given to the nylon toothed pulley situated below the camshaft pulley in a clockwise position on the belt drive (see diag item 4). This should be changed to a modified steel pulley (Ford No. 7053802) plus bolt (6701537). Ensure that the Camshaft and Injection Pump sprockets are free to rotate on the drive locations when the retaining bolts are slackened off. b) 4) a) b) c) Water Pump, Idler and Tensioner Pulleys Check that the belt running surfaces are not worn or damaged. Check that the flanges are running true and not damaged. Check that the water pump, and pulley bearings are in good condition, to ensure correct belt alignment. 5) Crankshaft Pulley The toothed pulley is in two parts. The rear section (Injection Pump Drive) is located onto the crankshaft by a small drive pin. The front section (Camshaft and “Poly V” belt drive) engages onto the rear pulley via a small vee protrusion on the rear face. Should the central fixing bolt for the crankshaft pulley come loose, or an old bolt re-used (Stretch bolt design), it is possible for fretting to take place damaging the locations. The crankshaft and camshaft pulleys can then move out of timing alignment, resulting in valve and piston contact damage. Replacement Procedure As the vehicle is fitted with two timing belts, one to drive the Camshaft, and one to drive the Injection Pump drives, which are driven off the crankshaft pulley, it is strongly recommended that both belts are replaced at the same time. NOTE: Special tools are required to lock the crankshaft, camshaft, and injection pump in the correct angular location when changing the belts, to ensure correct timing position. IMPORTANT: Ensure the engine is cold (not run for 4 hours) before commencing working as this will affect the setting of the timing belt tension and could lead to premature failure. Continued . . . .

6.0L DIESEL FUEL IN ENGINE COOLANT DIAGNOSTICS FORD: 2003-2005 Excursion 2003-2007 F-Super Duty 2004-2008 E-Series ISSUE Some 2003-2005 Excursion, 2003-2007 F-Super Duty and 2004-2008 E-Series vehicles equipped with a 6.OL engine may exhibit fuel in the engine coolant, due to leaks in the cylinder head fuel injector area. Symptoms may include fuel in engine coolant and coolant expulsion from the degas bottle. ACTION Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE Inspect the degas bottle for evidence of fuel in engine coolant. If diesel fuel is present, refer to the following Service Procedure. If not, follow normal diagnostics. NOTE IT IS VERY IMPORTANT TO ENSURE A COMPLETE FLUSHING OF THE ENGINE COOLING SYSTEM IS PERFORMED TO REMOVE ALL CONTAMINANTS FOLLOWING REPAIR. 1. Drain coolant from cooling system. 2. Remove all injectors from both cylinder heads. Refer to Workshop Manual (WSM), Section 313-04C. 3. Wipe injector bore clean of oil and fuel then apply a thin layer of bubbly type liquid hand soap, dish soap or laundry soap inside each injector bore. Ensure injector sleeve lip and cylinder head casting are coated with a soap layer. (Adding a small amount of water to the soap aids in creating bubbles) 4. Fit the cooling system pressure tester, refer to WSM, Section 303-03. (Do not add coolant) 5. Apply 5-10 psi (34-69 kPa) of air pressure to sealed cooling system. It is suggested to use a hand operated pressure tester or regulated shop air with tee in degas hose to degas bottle. NOTE MORE THAN 10 PSI (69 kPa) AIR PRESSURE CAN PUSH THE SOAP FROM THE LEAK POINT AND NO BUBBLES WILL BE PRESENT OR CREATED, MAKING DIAGNOSIS DIFFICULT. 6. Inspect each injector bore for bubbles. (A light and mirror or bore-scope may aid in pinpointing a leak location.) If bubbles are observed, determine if bubbles originate from the injector sleeve lip (Figure 1) or cylinder head casting. (Figure 2) Refer to cutaway view of the cylinder head. (Figure 3) a. Replace the injector sleeve if found to be leaking at sleeve lip, refer to WSM 303-04C. b. Replace cylinder head if leaking through casting, refer to WSM 303-01C. c. Flush cooling system, refer to another applicable Technical Service Bulletin (TSB) for proper cooling system flush procedures.
