2000-2002 Buick Century, Regal 2000-2001 Chevrolet Lumina 2000-2002 Chevrolet Impala, Monte Carlo 2000-2002 Pontiac Grand Prix 2000-2002 Oldsmobile Intrigue 1. 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

DISCONNECT LOWER RADIATOR HOSE 6. REMOVE RADIATOR NO.2 FAN SHROUD 7. A/T: DISCONNECT OIL COOLER HOSES 8. REMOVE RADIATOR Remove the 4 bolts and the radiator. DISASSEMBLY 1. REMOVE NO.1 FAN SHROUD Remove the 4 bolts and No. 1 fan shroud. 2. REMOVE RADIATOR SUPPORTS 3. REMOVE DRAIN PLUG 4. ASSEMBLE SST SST 09230-01010 a. Install the claw to the overhaul handle, inserting it in the hole in part “A” as shown in the diagram. b. While gripping the handle, adjust the stopper bolt so that dimension “B” shown in the diagram is 0.2 – 0.3 mm (0.008 – 0.012 inch). NOTICE: If this adjustment is not done, the claw may be damaged. 5. UNCAULK LOCK PLATES Using SST to release the caulking, squeeze the handle until stopped by the stopper bolt. SST 09230-01010 6. REMOVE TANKS AND O-RINGS a. Lightly tap the radiator port (inlet or outlet) with a soft faced hammer, and remove the tank. b. Remove the O-ring. REASSEMBLY 1. INSPECT LOCK PLATE Inspect the lock plate for damage. HINT: If the sides of the lock plate groove are deformed, reassembly of the tank will be impossible. NOTICE: The radiator can only be recaulked 2 times. After the 2nd time, the radiator core must be replaced. 2. INSTALL NEW O-RINGS AND TANKS a. After checking that there are no foreign objects in the lock plate groove, install the new O-ring without twisting it. HINT: When cleaning the lock plate groove, lightly rub it with sand paper without scratching it. b. Install the tank without damaging the O-ring. c. Tap the lock plate with a soft-faced hammer so that there is no gap between it and the tank. 3. ASSEMBLE SST 09230-01010 a. Install the punch assembly to the overhaul handle, inserting it in the hole in part “A” as shown in the illustration. b. While gripping the handle, adjust the stopper bolt so that dimension “B” shown in the diagram. Dimension “B”: 8.4 mm (0.34 inch) 4. CAULK LOCK PLATE

Please discard Corporate Bulletin Number 06-06-01-014B (Section 06 – Engine/Propulsion System). Condition Some customers may comment on a ticking or knocking type noise coming from the engine or transmission area. Cause Typically the noise is caused by either the transmission rear dust cover contacting the flexplate (refer to Corporate Bulletin Number 05-06-01-028) or a cracked flexplate (sometimes also referred to as a flywheel). Correction With the vehicle raised and supported on a suitable hoist, verify that the noise is coming from the flexplate area. If the noise is present, follow the procedure below. If the noise is not coming from the flexplate area, refer to Lower Engine Noise, Regardless of Engine Speed in SI. Important: The following information only applies to vehicles with the noise coming from the flexplate area.
