Subject: Models: Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination) 2000-2002 Buick Century, Regal 2000-2001 Chevrolet Lumina 2000-2002 Chevrolet Impala, Monte Carlo 2000-2002 Pontiac Grand Prix 2000-2002 Oldsmobile Intrigue Condition Some customers may comment that the low engine coolant level indicator is always illuminated. Cause The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator. Correction Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below. Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of “aftermarket” over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin. 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: • Light is on — Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI. • Light is out — Proceed to Step 4.

The cooling system components include the: 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. A closed water thermostat returns the engine coolant to the water pump. 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 failsafe 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 water pump (3.9L only): provides heater coolant flow boost. has a secondary function of providing engine-off cooling. Coolant Flow 3.9L
