REMOVAL & INSTALLATION
This procedure only applies to the 3.9L engine.
- Disconnect the negative battery cable.
- Drain the cooling system and disconnect the radiator upper hose at the coolant outlet elbow. Remove the two upper radiator retaining bolts.
- Raise the vehicle and safely support on jackstands. Drain the crankcase oil.
- Remove the splash shield and the automatic transmission oil cooling lines, if so equipped, then remove the radiator.
- Loosen and remove the fan belt, fan and pulley.
- Use a gear puller to remove the crankshaft pulley damper.
- Remove the cylinder front cover retaining bolts and gently pry the cover away from the block. Remove the gasket.
- Drive out the old seal with a pin punch from the rear of the cover. Clean out the recess in the cover.
- Coat the new seal with grease and drive it into the cover until fully seated. Check the seal to make sure that the spring around the seal is in the proper position.
- Clean the cylinder front cover and the gasket surface of the cylinder block. Apply an oil resistant sealer to the new front cover gasket and install the gasket onto the cover.
- Position the front cover assembly over the end of the crankshaft and against the cylinder block. Start, but do not tighten, the cover and pan attaching bolts. Slide a front cover alignment tool (Ford part no. T68P-6019-A or equivalent) over the crank stub and into the seal bore of the cover. Tighten all front cover attaching bolts to 12-18 ft. lbs. (16-24 Nm) and all oil pan bolts to 10-15 ft. lbs. (13-20 Nm). Tightening the oil pan bolts first.
Trim away the exposed portion of the old oil pan gasket flush with the front of the engine block. Cut and position the required portion of a new gasket to the oil pan and apply sealer to both sides.
- Lubricate the hub of the crankshaft damper/pulley with Lubriplate® to prevent damage to the seal during installation or on initial starting of the engine.
- Install and assemble the remaining components in the reverse order of removal.
- Start the engine and check for leaks.
