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 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

1989-1996 Dodge Dakota Trucks COIL Ignition Tests Manual

Dakota Trucks 1989-1996 Ignition Tests COIL The ignition coil for the vehicles covered by this guide is in the following locations: • 1989-92 engines: mounted to the firewall • 1993-96 2.5L engines: mounted on the thermostat housing in front of the coolant temperature sensor • 1993-96 V6 and V8 LDC engines: mounted to a bracket bolted to the right engine cylinder head • 1993-96 5.9L HDC engines: mounted to a bracket bolted to the air injection pump (AIR pump) mounting bracket. Fig. 2: Ignition coil mounting-all 1989-92 models Fig. 3: Ignition coil wiring and mounting hardware-1993- 96 2.5L engine 1. Inspect the ignition coil for arcing while the engine is running. If the engine will not start, this can be performed while the engine is cranked by either an assistant or a remote starter. Look at the coil in dim or low light to aid visibility of any arcing. Fig. 4: Ignition coil mounting-1993-96 3.9L and 5.2L/5.9L LDC engines 2. Arcing at the tower will carbonize the wire boot, which, if it is connected to a new ignition coil, will cause the coil to fail. In such cases, clean all the carbonization away or replace the components as necessary. Fig. 5: Ignition coil mounting-1993-96 5.9L HDC engine 3. Using a coil tester or ohmmeter according to the manufacturer’s instructions, test the primary and secondary resistance. Replace any coil that does not meet the specifications indicated in the accompanying chart. 4. Inspect the secondary coil wire for any sign of damage. Replace if any damage is found. Carbon tracking on the old wire can cause arcing and the failure of a new ignition coil. REMOVAL & INSTALLATION 1989-92 Models See Figures 6 and 7 1. Disconnect the negative battery cable. 2. Disconnect the three wires from the coil. Mark them to identify for installation. Fig. 6: Remove the coil bracket bolt at the cowl Fig. 7: Unscrew the coil mounting hardware, then remove the coil from the vehicle 3. Unplug the condenser suppressor connector from the coil, if equipped. 4. Unbolt and remove the coil. To install: 5. Bolt down the coil with old bolts. 6. Connect wires to coil making sure that the proper wires are connected where they should be. 7. Connect the condenser suppressor, if equipped. 8. Connect the battery negative cable Removal and Installation V6 AND V8 ENGINES 1. Disconnect the negative battery cable. 2. Disconnect the primary wiring from the ignition coil. 3. Disconnect the secondary spark plug wire from the coil. 4. Remove the two bolts and withdraw the coil from its mounting bracket. To install:
5. Position the coil on its bracket and install the two bolts. Tighten them to 100 inch lbs. (11 Nm). If the bracket has been tapped for coil mounting bolts, these fasteners require less torque, so tighten them to 50 inch lbs. (5 Nm). 6. Connect all wiring to the ignition coil. TESTING See Figure 1 The only test you can perform without a DRBII scan tool, or equivalent, is a basic check of the sensor only.
