Fig. 5.47. Location of oil pan mounting bolts for the 2.5L Duratec-V15 engine.
You will need a set of socket heads.
The engine oil pan flange is sealed with FORD WSE-M4G323-A4 sealant-gasket, there is no gasket. If oil leakage occurs, the seal must be replaced.
NOTE: Perform work on an inspection pit, overpass or lift.
1. Drain the oil from the engine (see Changing engine oil and oil filter).
2. Remove the oil cooler assembly.
To do this, remove the two clamps securing the oil hoses and unscrew the four bolts securing the oil cooler to the oil pan.
3. Remove the bolts securing the gearbox to the oil pan.
4. Unscrew the twenty-nine bolts (Fig. 5.47) securing the oil pan to the engine cylinder block, carefully pry it up with a screwdriver and remove the oil pan.
5. Clean the mating surfaces of the oil pan and cylinder block from old sealant.
6. Apply a special sealant-gasket (FORD WSE-M4G323-A4 or its equivalent) to the mating surface of the oil pan with a 3 mm diameter roller, and the line of application of the sealant-gasket should pass from the inside of the mounting holes.
7. No later than 10 minutes after applying the sealant, install the oil pan on the cylinder block and screw in the pan mounting bolts without tightening.
WARNING: To ensure a tight seal, the following two steps must be completed within 5 minutes of installing the crankcase.
8. Screw in the gearbox mounting bolts to the oil pan.
9. Tighten the crankcase mounting bolts crosswise to 24 N·m.
10. Fill the engine with oil (see Changing engine oil and oil filter).
NOTE: You can fill the oil and start the engine no earlier than one hour after installing the oil pan: this time is necessary for the sealant to polymerize.
