1. Disconnect engine coolant temperature sensor electrical connector and inspect sensor and connector terminals for corrosion and/or evidence of engine coolant. ^If terminals are corroded or if there is evidence of engine coolant proceed to step 4. ^If terminals are not corroded and there is no evidence of engine coolant, reconnect the electrical connector and continue to next step. 2. Perform one or both of the following checks to determine whether the engine coolant temperature sensor is providing the correct temperature indication. If engine coolant temperature sensor reading does not pass either of the above tests, continue with next step. ^If engine is at ambient temperature (vehicle has been sitting overnight or not started for several hours), use a Scan tool to compare the inlet air temperature ( IAT ) to the engine coolant temperature ( ECT ). These two readings should be within 2°C (4°F) of each other. ^If engine is at operating temperature, install a thermometer in the coolant recovery reservoir. With the engine running and A/C off, use a Scan tool to compare the engine coolant temperature sensor reading to the thermometer reading. These two readings should be within 8°C (15°F) of each other If engine coolant temperature sensor reading passes both of the tests above, refer to appropriate symptom diagnostic chart in the Engine/Emissions Controls Section of applicable Engine Service Manual. 3. Turn ignition off. 4Remove coolant surge tank cap. 5. Drain at least 1.9 L (2 Qt.) of engine coolant from the cooling system by opening radiator drain valve or removing engine drain plug. Collect engine coolant in a container. 6. Disconnect engine coolant temperature sensor electrical connector. 7. Remove engine coolant temperature sensor from cylinder head. 8. Obtain replacement engine coolant temperature sensor (P/N 21025106). 9. Use appropriate tap to clean sensor mounting hole of any thread sealant residue. 10. Install engine coolant temperature sensor in cylinder head. Torque: Engine Coolant Temperature Sensor: 8 Nm (71 in-lbs) 11. Inspect harness connector terminals for corrosion and/or evidence of engine coolant. If harness connector terminals are corroded or there is evidence of engine coolant, the harness connector must be replaced with new connector (P/N 12117087-includes: connector, terminals, wires, and splice sleeves). 12. Connect engine coolant temperature sensor connector. 13. Transfer engine coolant drained in step 5 into coolant surge tank. If necessary fill coolant surge tank to the FULL COLD range with 50/50 solution of correct type of antifreeze and clean water. 14. Start engine and check for leaks. 15. Run engine until upper radiator hose is hot, then add additional coolant if needed to bring the level to the FULL COLD level (1991-early 1997) or within the Min./Max. cold range (late l997-2001). 16. Install coolant surge tank cap.

NOTE: Less than 80% of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement. 1. Release the pressure in the cooling system by slowly turning the pressure relief cap one half to one turn counterclockwise to the first stop on the filler neck. When the pressure has been released, remove the pressure relief cap. 2. Raise and support the vehicle, For additional information, refer to Section 100-02 . 3. Remove the lower radiator cover. 4. Place a suitable container below the radiator draincock. Drain the coolant. 5. Close the radiator draincock when finished. Filling and Bleeding with RADKITPLUS 1. Using the special tool, install the RADKITPLUS and follow the RADKITPLUS manufacturer’s instructions to fill and bleed the cooling system. Filling without RADKITPLUS CAUTION: Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level. When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water. To maintain the integrity of the coolant and the cooling system: * Add Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A. * Do not add Motorcraft Specialty Engine Coolant such as VC-2 or an equivalent meeting Ford specification WSS-M97B44-D. Mixing coolants can degrade the coolant’s corrosion protection. * Do not add alcohol, methanol, or brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing. * Do not mix with recycled coolants unless they meet the requirements of Ford specification ESE-M97B44-A or WSS-M97B51-A1. Not all coolant recycling processes meet these Ford specifications. Use of such coolants can harm the engine and cooling system components. All engines 1. Install the lower radiator cover.

Draining and Filling Cooling System Notes Draining and Filling Cooling System Draining Procedure Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240 000 km, (150,000 ml) , whichever occurs first. 1. Park the vehicle on a level surface. 2. Remove and clean the coolant recovery reservoir. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap its removed while the engine and radiator are still hot. 3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap. Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound. 4. Place a drain pan under the radiator drain cock in order to collect all of the used coolant. 5. Open the radiator drain cock. If only partial cooling system draining is required, drain enough coolant to perform the procedure 6. Open the air bleed valve on the thermostat housing 2 full turns. 7. Open the air bleed valve above coolant pump 2 full turns. 8. Place a drain pan under the engine block drains in order to collect the used coolant. Important: Allow the coolant to drain completely

Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL® mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin. 2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section. 3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light: Subject: Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination) Models: 2000-2002 Buick Century, Regal 2000-2001 Chevrolet Lumina 2000-2002 Chevrolet Impala, Monte Carlo 2000-2002 Pontiac Grand Prix 2000-2002 Oldsmobile Intrigue • Light is on — Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI. • 4. With the key off, connect the coolant level sensor into the vehicle’s wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds. 5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Reinstall the low coolant sensor into the vehicle and proceed to Step 6. 6. Flush the cooling system and install new DEX-COOL® mixture as outlined in the SI. Check the vehicle’s warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination
