Lincoln LS 1st GEN // 2000-2002 // V8 only
- Engine Cooling
The cooling system components include:
The water thermostat:
The degas bottle:
The fan blade draws air through the radiator to help cool the engine coolant.
The fan motor:
The Engine Coolant flows:
An open water thermostat allows the engine coolant to flow to the radiator.
Unsatisfactory coolant materials:
The Cylinder Head Temperature Sensor provides a signal to the temperature gauge.
The optional Block Heater:
The Auxiliary Coolant Flow Pump (3.9L only):
The Dual Coolant Control Valve:
- Coolant Flow 3.9L
All Plastic cooling system parts should be replaced all at once !!!
# 2 - XW4Z-8260-BA - Upper Radiator Hose
# 3 - XW4Z-8A520-AF - Coolant Outlet Pipe
# 12 - 5W4Z-8A080-AA - Degas Bottle
# 15 - XW4Z-8592-AA - Thermostat Housing << see note here
# 19 - 1W4Z-8286-CA - Lower Radiator Hose (with Oil Cooler)
# 19 - 1W4Z-8286-DA - Lower Radiator Hose (without Oil Cooler)
Items listed below, should really be replaced at the same time when completing the cooling system rebuild. They age and deteriorate at the same rate as the rest of the system. They may be good now but tend to go around the same time the other plastics begin to fail. While rebuilding the cooling system, lines will be off and coolant out anyhow, so the timing is now.

- Engine Cooling
The cooling system components include:
- block heater (optional)
- cylinder head temperature sensor
- fan blade, fan motor and fan shroud assembly
- radiator
- pressure relief cap
- degas bottle
- radiator draincock
- water pump
- oil cooler (optional)
- water thermostat
The water thermostat:
- controls the engine coolant temperature.
- allows quicker engine warm-up.
The degas bottle:
- provides a location for system fill.
- contains coolant expansion and system pressurization.
- provides air separation during operation.
- replenishes the engine coolant to the system.
The fan blade draws air through the radiator to help cool the engine coolant.
The fan motor:
- operates only when the engine is running.
- will not operate when the engine is off.
The Engine Coolant flows:
- from the lower radiator hose to the water pump.
- from the water pump to the engine block and the cylinder heads.
An open water thermostat allows the engine coolant to flow to the radiator.
Unsatisfactory coolant materials:
- Alcohol-type antifreeze does not provide adequate water pump lubrication.
- has lower boiling point
- reduced antifreeze protection
- Alkaline brine solutions will cause serious engine cooling system damage.
The Cylinder Head Temperature Sensor provides a signal to the temperature gauge.
- will invoke Fail-Safe cooling.
The optional Block Heater:
- electrical heating element is installed in the block cooling jacket.
- uses a standard 110V (220V in Europe) electrical supply
- keeps the engine coolant warm during cold weather.
The Auxiliary Coolant Flow Pump (3.9L only):
- provides heater coolant flow boost at low RPM's.
- has a secondary function of providing engine-off cooling.
The Dual Coolant Control Valve:
- is controlled by the DATC module (Dual Automatic Temperature Control).
- provides individual front occupant temperature control.
- Coolant Flow 3.9L

# 1 - 18495 - Dual Coolant Control Valve ( DCCV )
CAUTION: both GEN I & II repair manuals show DCCV as P/N 18495
~ one would want to be very careful ordering P/N 18495
XW4Z-18495-AA // Gen 1 only // has 5 connections
MOTORCRAFT Part # YG355
2R8Z-18495-AA // Gen 2 only // has 3 connections
