z
System pressure is limited by an integral, internally- vented relief valve which directs the
bypassed oil back to the inlet side of the oil pump.
z Oil pump displacement has been selected to provide adequate volume to ensure correct oil
pressure both at hot idle and maximum speed.
z The relief valve calibration protects the system from excessive pressure during high viscosity
conditions.
z The relief valve is designed to provide adequate connecting rod bearing lubrication under high-
temperature and high- speed conditions.
Cooling System
The engine cooling system includes the following:
zradiator
z coolant pump
z the electric cooling fan motor and fan blade, activated by the variable control module
z the degas bottle, which aids in maintaining the correct volume of engine coolant
z thermostat
z upper radiator hose
z lower radiator hose
z heater coolant hoses
Drive Belt System
The 4.6L (4V) DOHC engine is equipped with a serpentine drive belt. To ensure maximum life, a
replacement drive belt should be of the same type as originally installed.
zThe accessories mounted on the front of the engine are belt- driven by the crankshaft.
z The serpentine drive belt is routed over each accessory pulley, driven by the crankshaft pulley
bolted to the crankshaft. For service procedures, including tensioning, refer to Section 303 - 05 . Klj . 3 ba

Installation
1. NOTE: The crankshaft pulley must be installed within four minutes after applying the silicone.
Apply silicone to the Woodruff key slot on the crankshaft pulley. zUse Silicone Gasket and Sealant F7AZ-19554- EA or equivalent meeting Ford
specification WSE-M4G323- A4.
2. Using the special tool, install the crankshaft pulley.
3. Install the bolt and washer. Tighten the bolt in four stages. zStage 1: Tighten the bolt to 90 Nm (66 lb- ft).
z Stage 2: Loosen the bolt one full turn.
z Stage 3: Tighten the bolt to 50 Nm (37 lb- ft).
z Stage 4: Tighten the bolt an additional 90 degrees.
4. Lower the vehicle.
