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
