TROUBLE SHOOTING

Note. To trouble shoot mechanical engine components, see appropriate table in TROUBLE SHOOTING article in GENERAL INFORMATION.

REMOVAL & INSTALLATION

Note. For reassembly reference, label all electrical connectors, vacuum hoses and fuel lines before removal. Also place mating marks on engine hood and other major assemblies before removal.

COOLING SYSTEM BLEEDING

Fill radiator until coolant level is 1.5" (38 mm) below cap seal in filler neck on radiator. Install radiator cap. Start engine and warm engine to normal operating temperature. Shut off engine. Allow engine to cool. Remove radiator cap and recheck coolant level. Add coolant if necessary.

FUEL LINE DISCONNECT FITTINGS

Note. Fuel lines may contain spring lock coupling or a push lock coupling. (Scheme 100)and (Scheme 101). Determine type of disconnect fitting used and use proper procedure for proper disconnect fitting.

Relieving Fuel Pressure

Place container under fuel filter/water separator drain hose. Open drain valve on fuel filter/water separator and allow fuel to drain into container. When filter is drained, close drain valve.

Preliminary Inspection

1. Disconnect air intake tube and exhaust pipe from turbocharger. Rotate turbine wheel, shaft assembly and compressor wheel inside turbocharger. Shaft assembly should rotate smoothly. Perform STEP 1. (Scheme 121)
2. Push compressor wheel and shaft assembly as far in one direction as possible while rotating shaft assembly. Ensure compressor wheel does not contact compressor housing while rotating shaft assembly. Push turbine wheel and shaft assembly as far in one direction as possible while rotating shaft assembly. Ensure turbine wheel does not contact turbine housing while rotating shaft assembly.
3. If compressor wheel or turbine wheel does not contact housing while rotating shaft assembly, bearings in turbocharger are okay. Go to next step. If compressor wheel or turbine wheel contacts housing while rotating shaft assembly, bearings in turbocharger are defective. Replace turbocharger.
4. Install dial indicator so stem on dial indicator contacts end of shaft assembly at compressor wheel. Perform STEP 2. (Scheme 121) Push shaft assembly as far in one direction as possible and zero dial indicator. Push shaft assembly as far in opposite direction and note shaft end play.

Scheme 121

ENGINE LUBRICATION SYSTEM

Note. Engine contains a high-pressure oiling system and a low-pressure oiling system.

High-Pressure Oiling System

High-pressure oiling system supplies oil pressure for fuel injector operation. (Scheme 109) During initial start or cold start, gear-driven high-pressure oil pump receives unfiltered engine oil from driver's side valve lifter oil galley through anti-drain check ball. Once engine starts, or during warm engine starts, anti-drain check ball closes and high-pressure oil pump receives filtered engine oil from high-pressure oil pump reservoir. High-pressure oil pump delivers engine oil through oil rail in cylinder head at pressures of 600-3000 psi (42.19-210.93 kg/cm 2 ) to fuel injectors.

Low-Pressure Oil System

Crankshaft-driven low-pressure oil pump supplies pressurized lubrication for engine oiling system. (Scheme 122) Oil cooler is used cooling of engine oil.

Scheme 122

Crankcase Capacity

Crankcase capacity is 13 qts. (12.3L) with oil filter.

Oil Pressure

Oil pressure should be 40-70 psi (2.8-4.9 kg/cm 2 ) at 3300 RPM with engine at normal operating temperature.

For servicing of high-pressure oil pump, see HIGH-PRESSURE OIL PUMP under REMOVAL & INSTALLATION.

Removal & Disassembly

1. Low-pressure oil pump is located on front cover. (Scheme 122) Remove vibration damper. See «CRANKSHAFT FRONT SEAL»(/ford/econoline/i-1985-2013/remont/mechanical/#engine-73l-v8-turbo-diesel-vin-f) under REMOVAL & INSTALLATION.
2. Remove bolts, low-pressure oil pump body, outer gerotor and inner gerotor. (Scheme 123)

1. Inspect components for damage and wear. Install inner and outer rotors in low-pressure oil pump body. Place straightedge across low-pressure oil pump body so it is above both rotors. Using feeler gauge, measure rotor end clearance between rotor and straightedge. Rotor end clearance should be .0010-.0030" (.025-.076 mm).
2. With both rotors installed in low-pressure oil pump body, use feeler gauge to measure clearance between outer edge of outer gerotor and oil pump body. Outer gerotor-to-oil pump body clearance should be .028-.032" (.71-.81 mm). Replace low-pressure oil pump if any measurement is not within specification.

Reassembly & Installation

1. To reassemble, reverse disassembly procedure. Ensure components are installed in original location.
2. To install, reverse removal procedure using "O" ring. Ensure outer gerotor is lubricated with engine oil before installing low-pressure oil pump body. Install and tighten low-pressure oil pump body-to-front cover bolts.
3. Manufacturer recommends installing NEW crankshaft front seal any time vibration damper is removed. For proper installation procedure of crankshaft front seal, see «CRANKSHAFT FRONT SEAL»(/ford/econoline/i-1985-2013/remont/mechanical/#engine-73l-v8-turbo-diesel-vin-f) under REMOVAL & INSTALLATION.

Scheme 123

1. Disconnect negative battery cable(s). Drain cooling system. Raise and support vehicle.
2. Disconnect exhaust pipe at turbocharger for access to oil cooler if necessary. Remove oil cooler front header-to-cylinder block bolts. (Scheme 124) Drain engine oil and remove oil filter.
3. Disconnect retainer and cable from cylinder block heater. Cylinder block heater is located on driver's side rear corner of cylinder block, just below exhaust manifold, near oil filter.
4. Remove oil cooler rear header-to-cylinder block bolts. (Scheme 124) Remove oil cooler assembly and gaskets. Perform oil cooler leakage test to ensure oil cooler is not defective.

Oil Cooler Leakage Test

1. Using NEW gaskets, install Oil Cooler Leakage Tester (014-00944), on 1996 models or (014-00726) on 1997 models, onto oil cooler assembly. Apply 40 psi (2.8 kg./cm 2 ) of air pressure on fitting on coolant side of oil cooler front header.
2. Inspect for air leakage at plastic tubes and at oil cooler front and rear header cover plates. If no air leakage exists, place plastic tubes into a cup of water and check for bubbles.
3. If no bubbles exist, no internal leak exists and oil cooler is okay. If bubbles exist, an internal leak exists in oil cooler. If internal leak exists, disassemble oil cooler assembly and replace oil cooler.
4. Release air pressure. Remove oil cooler leakage tester.

Disassembly & Cleaning

1. Using soft-faced hammer, tap on oil cooler front and rear headers to loosen "O" rings. Remove oil cooler front and rear headers from oil cooler by using twisting motion.
2. Thoroughly clean all components with solvent. Ensure oil cooler is thoroughly flushed to ensure all residue is cleaned from oil cooler. Dry components with compressed.

Reassembly

1. Apply engine oil onto NEW "O" rings and "O" ring mating surfaces. Install large "O" rings and then small "O" rings onto oil cooler.
2. Install oil cooler front and rear headers onto oil cooler. Ensure locating clips align in slots and headers are installed evenly onto oil cooler. Perform oil cooler leakage test to ensure oil cooler is properly sealed.

1. Using NEW gaskets, install oil cooler assembly onto cylinder block. Install and tighten oil cooler rear header-to-cylinder block bolts until bolts are snug. Install and tighten oil cooler front header-to-cylinder block bolts to specification. See «TORQUE SPECIFICATIONS»(/ford/econoline/i-1985-2013/remont/mechanical/#engine-73l-v8-turbo-diesel-vin-f__torque-specifications) .
2. Lower engine. Install driver's side engine mount. Tighten oil cooler rear header-to-cylinder block bolts to specification. See «TORQUE SPECIFICATIONS»(/ford/econoline/i-1985-2013/remont/mechanical/#engine-73l-v8-turbo-diesel-vin-f__torque-specifications) . To install remaining components, reverse removal procedure. Adjust engine oil level. Fill and bleed cooling system. See «COOLING SYSTEM BLEEDING»(/ford/econoline/i-1985-2013/remont/mechanical/#engine-73l-v8-turbo-diesel-vin-f__cooling-system-bleeding) under REMOVAL & INSTALLATION.

Note. If engine oil leaked into cooling system due to defective oil cooler, drain and flush cooling system as necessary. If coolant leaked into crankcase due to defective oil cooler, change engine oil and oil filter.
