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

1984-1998 Jeep Wagoneer/ Commando/ Cherokee Emission Controls Crankcase Ventilation System (PCV/CCV)

CCV Fitting See Figures 2 and 3 1. With the engine running, remove the CCV fitting. a. If the fitting is not plugged, a hissing noise will be heard as air passes through the valve. A strong vacuum should also be felt when a finger is placed over the fitting. b. Install the CCV fitting. c. Remove the fresh air hose from the air cleaner assembly and loosely hold a piece of paper over the open end of the hose. After allowing about one minute for the crankcase pressure to reduce, the paper should be sucked against the opening with a noticeable amount of force. 2. Turn the engine OFF . Remove the metered orifice fitting, and check for a plugged condition. A clicking noise should be heard to indicate that the valve mechanism is free. 3. If the crankcase ventilation system meets the tests in Steps 1 and 2 above, no further service is required. If not, the CCV fitting must be cleaned and the system checked again. 4. If Step 1c fails when the CCV fitting is cleaned, it will be necessary to replace the molded vacuum hose with a new one, and to clean the metered orifice port. 5. Clean or replace the engine air cleaner filter element with a new one-for more details, refer to the air cleaner procedure located in General Information & Maintenance. Fig. 2: CCV system diagram for 4.0L engine Fig. 3: CCV system diagram for the 2.5L engine Evaporative Emission Control System OPERATION The evaporative emission control system prevents the release of unburned hydrocarbons, from gasoline or gasoline vapor, into the atmosphere. When pressure in the fuel tank is below 3 psi (20 kPa), the pressure relief/rollover valves open allowing fuel vapors to flow to the evaporative canister where they are absorbed by a charcoal mixture. This prevents excessive pressure buildup in the fuel system. Most canisters are equipped with a calibrated orifice at the inlet to the canister.
