All engines are equipped with a high quality full-flow, disposable type oil filter. 1. Raise and support the vehicle. 2. Remove the belly pan retainers (1) and remove the belly pan. 3. Position a drain pan under the oil filter. 4. Using a suitable oil filter wrench, rotate the oil filter (1) counterclockwise to remove… Read More »
CAUTION: If the engine encounters a catastrophic failure, the engine oil cooler must be replaced or damage to the new engine and/or components could result. NOTE: Whenever the oil cooler is serviced, the rubber O-ring seal must be replaced. 1. Clean the sealing surface of the oil cooler (2) and install a new rubber O-ring… Read More »
CAUTION: If the engine encounters a catastrophic failure, the engine oil cooler must be replaced or damage to the new engine and/or components could result. 1. Raise and support the vehicle. 2. Remove the belly pan retainers (1) and remove the belly pan. 3. Drain the cooling system. Refer to STANDARD PROCEDURE . 4. Remove… Read More »
The engine oil cooler (2) is engineered for maximum cooling efficiency with no restriction in oil flow. The oil cooler is a stack plate design coolant-to-oil heat exchanger. The oil cooler (2) is mounted between the oil filter (1) and the engine block. The oil cooler uses the radiator coolant system; coolant is circulated through… Read More »
1. Lubricate the Variable Valve Timing Solenoid (VVTS) rubber O-ring seal with clean engine oil. 2. Install the VVTS and rotate into position. 3. Install the VVTS (3) retaining bolt (2) and tighten to 11 N.m (8 ft. lbs.). 4. Connect VVTS electrical connector (1). 5. Install intake manifold. Refer to MANIFOLD, INTAKE, REMOVAL.
NOTE: The Variable Valve Timing Solenoid (VVTS) (3) is located under the intake manifold. 1. Remove intake manifold. Refer to MANIFOLD, INTAKE, REMOVAL. 2. Disconnect VVTS electrical connector (1). 3. Remove VVTS retaining bolt (2). NOTE: To remove the VVTS, the engine must be at room temperature. 4. Rotate the VVTS to break the seal… Read More »
The Variable Cam Timing (VCT) assembly is actuated with engine oil pressure. The oil flow to the VCT assembly is controlled by an Variable Valve Timing Solenoid (VVTS). The VVTS consists of a Pulse Width Modulated (PWM) solenoid and a spool valve. The PCM actuates the VVTS to control oil flow through the spool valve… Read More »
The 6.4L engine is equipped with Variable Valve Timing (VVT). This system uses a Variable Valve Timing Solenoid (VVTs) to control the oil pressure to direct oil pressure to the camshaft phaser assembly. The camshaft phaser assembly advances and/or retards camshaft timing to improve engine performance, mid-range torque, idle quality, fuel economy and reduce emissions.… Read More »
Since it is sometimes difficult to determine the source of an oil leak in the rear seal area of the engine, a more involved inspection is necessary. The following steps should be followed to help pinpoint the source of the leak. If the leakage occurs at the crankshaft rear oil seal area: 1. Disconnect the… Read More »
1. Remove the PCV valve, cap or plug the PCV valve port at the intake manifold. 2. Attach an air hose with a pressure gauge and regulator onto the dipstick tube. CAUTION: Do not subject the engine assembly to more than 20.6 kPa (3 PSI) of test pressure. 3. Gradually apply air pressure from 1… Read More »
