1999 Saturn SL1 L4-1.9L SOHC VIN 8 Engine – Driveability Concerns/ Cooling System DTC’s Set

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.


Removal & Disassembly Remove engine front cover. See FRONT COVER & TIMING CHAIN under REMOVAL & INSTALLATION. Using an impact driver and a T-30 Torx bit, remove and discard oil pump cover plate screws. Remove cover plate and rotors. See Fig. 11 . To remove oil pump relief valve, use a slide hammer and Relief Valve Puller Adapter (SA9103E). Inspection Replace rotors if worn or damaged. Using feeler gauge and straightedge (at cover plate), measure oil pump clearances. See OIL PUMP SPECIFICATIONS table. If clearances are not as specified, replace rotors or entire pump assembly as necessary. Reassembly & Installation Install rotors with chamfer facing away from engine. Install new relief valve (if removed). Pack pump rotors with petroleum jelly to prime pump. Install pump cover plate using new screws. Tighten screws to specification. See TORQUE SPECIFICATIONS .

Removal 1. Disconnect negative battery cable. Raise and support vehicle. Drain engine oil. Remove right front wheel and splash shield. Put a block of wood between cradle and engine torque strut at bottom front end of engine. See Fig. 2 . 2. Remove mount from upper front end of engine, allowing engine to rest on wood block. Remove accessory drive belt and tensioner. Remove accessory belt idler. Remove cylinder head cover. 3. Replace silicone isolators on cylinder head cover screws if deteriorated. Remove power steering pump (leave hoses attached). Remove A/C compressor (leave hoses attached). Raise and support vehicle. Drain engine oil. Remove right front wheel and splash shield. 4. Remove support bracket between intake manifold and engine block. Remove front balancer/pulley using a 3-jaw puller. Disconnect exhaust pipe from exhaust manifold. Install Crankshaft Gear Retainer (SA9104E) onto end of crankshaft, with flat side toward crankshaft gear (sprocket). Crankshaft gear retainer holds crankshaft gear in place during removal of front cover. 5. Remove 4 bolts from front end of oil pan. Using RTV Cutter (SA9123E), cut RTV sealant between oil pan and front cover. Spray penetrating oil onto front cover dowel pins. Remove front cover bolts (one bolt is located above accessory drive belt pulley). Pry front cover from engine block. 6. To prevent pistons from hitting valves, turn crankshaft 90 degrees clockwise as viewed from front of engine until timing mark and keyway are aligned with split line of main bearing cap. Remove timing chain tensioner, guides and chain. While using a 7/8″ (21 mm) wrench to keep camshaft(s) from turning, remove camshaft sprocket bolt(s). Remove camshaft sprocket(s). Installation 1. To prevent pistons from hitting valves, ensure timing mark and keyway on crankshaft are aligned with split line of main bearing cap. Install camshaft sprocket(s) with the letters FRT (front) facing away from cylinder head. Use a 7/8″ (21 mm) wrench to keep camshaft(s) from turning. 2. Install and tighten camshaft sprocket bolt(s) to specification. Rotate camshaft(s) until a 3/16″ (4.8 mm) drill bit can be inserted through timing pin hole(s) and into cylinder head. See Fig. 5 or Fig. 6 . 3. Rotate crankshaft counterclockwise as viewed from front of engine until timing marks at crankshaft sprocket are aligned. Install timing chain, aligning Silver-plated chain links with timing mark(s) on camshaft sprocket(s) and bottom tooth (or teeth) of crankshaft sprocket. See Fig. 5 or Fig. 6 . 4.

Rotary Fuel Pumps Timing to engine steps

SMALL | MEDIUM | LARGE Previous Next Fuel Injection Pump (Distributor Type) The fuel injection pumps, Bosch® VE, Lucas CAV DPA, Stanadyne DB4, Lucas CAV DPS, and Delphi DP210, are rotary distributor pumps. These pumps perform the four basic functions of: 1. Producing the high fuel pressure required for injection 2. Metering the exact amount of fuel for each injection cycle 3. Distributing the high-pressure, metered fuel to each cylinder at the precise time 4. Varying the timing relative to engine speed. SMALL | MEDIUM | LARGE Previous Next Distributor-Type Pump Governor Balance between the governor flyweights and control lever position controls the metering of the amount of fuel to be injected. The fuel injection pump governor performance and setting can affect engine power. Special equipment and qualified personnel are required to verify governor performance. If the seals are broken on the external Bosch® VE adjustment screw, the fuel rate can, perhaps, be out of adjustment The Lucas CAV DPA/DPS fuel injection pump uses a coded spring connection to change the governor setting. Incorrect connection of the governor spring can affect performance. Adjustments and rating changes are described in the Master Repair Manual, Injector Pumps and Injectors, Manual Shutdown Levers Both fuel injection pumps are equipped with mechanical shutdown levers. These levers are spring-loaded in the run position. Not all applications will use these manual shutdown controls and there will be no cable or rod connected to the lever. NOTE: Partial actuation of the mechanical shutdown levers will affect fuel flow and engine power. SMALL | MEDIUM | LARGE Previous Next Advance Timing Mechanism Regulated pressure produced by a vane supply pump in both fuel injection pumps is used to advance the timing as the engine speed increases. A return spring is used to retard the timing as the engine speed is reduced. If a spring breaks, the timing will go to the advance position, resulting in torque loss, fuel knock, and possible engine overheating. Retarded (late) timing will result in torque loss, high fuel consumption, and white to black smoke. SMALL | MEDIUM | LARGE Previous Next The Lucas CAV DPA/DPS advance timing mechanism uses a check ball in the circuit which, if omitted during assembly, will result in no timing advance. If the fuel injection pump has been replaced or the mechanism has been removed to fix a leak, the problem can be that the check ball is missing
