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

1985 Chevrolet 305 HIGH-FLO T.P.I. RUNNERS INSTALLATION MANUAL

download
INSTALLATION PROCEDURE 1. Disconnect battery negative cable. 2. Disconnect throttle body from Mass Air Flow Sensor boot and disconnect all lines from throttle body (linkage, water, vacuum, etc.). 3. Remove linkage attachments from plenum and move out of the way. Disconnect plenum from runners and remove (it is not necessary to remove throttle body from plenum). You may need to loosen lower runner bolts in order to free plenum. 4. Remove runners from baseplate and loosen, but do not remove the fuel rails. 5. Trial fit your new intake runners prior to final installation on your vehicle. This way you can get a “feel”for what goes where and why. NOTE: Because of varying O.E.M. fuel line routing, some material may need to be removed from the runners in order to clear the fuel lines. Check for clearance before installing onto engine. 6. Thoroughly clean the flange surfaces of the plenum, runners, and baseplate and remove any remaining gasket material. Use rags or paper towels in the open ports to make sure your intake system is kept free of all foreign objects (i.e., dirt, gasket material, etc.). 7. Place runners into position on the baseplate making sure to use the proper runner/gasket on the proper side and start bolts. 8. Tighten down fuel rails and place plenum into position. Start bolts, but do not tighten (make sure proper gaskets are used). 9. Align plenum and runners and tighten all runner and plenum bolts. 10. Reconnect all connections and linkage to the throttle body and reconnect the throttle body to Mass Air Flow Sensor boot. If clearance is a problem, it may be necessary to discard the original steel hard line which runs from the O.E.M. baseplate to a rubber hose connecting to the charcoal canister and replace with a rubber hose. On the passenger’s side of the engine, discard the original hard line (if so equipped) which ran from the valve cover vent to the throttle body and replace with 3/8″ rubber hose if necessary for clearance. 11. Check and top off any lost coolant, reconnect battery, and start engine and run briefly, monitoring the “check engine”light. Turn off engine and check installation for any leaks or abnormalities
