Subject: FRONT FUEL FEED - . HOSE ASSEMBLY
Models/Years: SOME 1988 & 1989 CUTLASS CALAIS MODELS WITH QUAD 4 ENGINES (VIN CODE'D")
NOTICE: THIS SAFETY RECALL HAS BEEN EXPANDED (SEE REVISED 'VEHICLES INVOLVED' SECTION). ALSO, AN "IMPORTANT" NOTE HAS BEEN ADDED TO THE SERVICE PROCEDURE AT STEP 5 AND THE PARTS INFORMATION FOR O-RINGS AND RETAINERS HAS BEEN REVISED. DEALERS SHOULD REVIEW THE "DEALER ACTION' SECTION AND ACT ACCORDINGLY. THIS BULLETIN CANCELS AND SUPERSEDES PRODUCT CAMPAIGN BULLETIN 89-C-10, WHICH SHOULD BE DISCARDED.
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1988 and 1989 Oldsmobile Cutlass Calais model vehicles equipped with Quad 4 engines (RPO LD2, VIN Code'D'). The Front Fuel Feed Hose Assembly could crack or separate at the coupling on the engine end of the hose assembly, allowing fuel to leak into the underhood area. Under certain circumstances, this could result in an underhood fire.
To prevent this condition from occurring, dealers are to inspect, and if required, replace the Front Fuel Feed Hose Assembly on involved vehicles.
VEHICLES INVOLVED
Some 1988 and 1989 Oldsmobile Cutlass Calais vehicles equipped with Quad 4 engines (RPO LD2; VIN Code "D") within the VIN breakpoints listed below:
Through & Year Assembly Plant Beginning Including ---- -------------- --------- ---------
1988 Lansing North JM248891 JM277820
1989 Lansing North KM220636 KM309890 End of Production
Where P/N 24570910 hose is known to have been used for a prior warranty replacement of the Front Fuel Feed Hose Assembly, the vehicle has been deleted from the dealers VIN list. Also, this recall EXCLUDES a test fleet of vehicles built with LGO, VIN Code "A" Quad 4 engines and P/N 24570910 hoses near the end of 1989 production.
Involved vehicles repaired for the above described condition prior to this campaign will still require correction if a P/N 2457091 0 hose assembly was not used.
All vehicles which are listed on the dealers campaign printout will require inspection/correction as outlined in the SERVICE PROCEDURE section of this bulletin.
Should a question arise concerning the campaign involvement of a specific vehicle(s) within the breakpoints listed above, dealers should access the Vehicle Information Service System (V.I.S.S.) for verification.
DEALER ACTION
Dealers are to perform this campaign on all, involved vehicles at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your new or used vehicle inventory and arrange for the campaign correction to be performed.
SERVICE PROCEDURE
1. Raise and support the hood. Examine the Front Fuel Feed Hose Assembly. if the hose assembly is a P/N 2457091 0 part, as shown in Figure 1, proceed directly to Step. 9. Otherwise, proceed to Step 2.
2. Note owners radio station choices, then disconnect negative battery cable and remove fuel tank filler cap.
3. Relieve pressure in fuel system following instructions below:
CAUTION:
To reduce the risk of fire and personal injury, it is necessary to relieve fuel system pressure before servicing fuel system components, otherwise fuel spray could occur. Have a dry chemical (Class B) fire extinguisher near the work area.
A. Connect fuel gage J 34430-1 or equivalent to fuel pressure connection. Wrap a shop cloth around fitting while connecting gage to collect fuel. Then place cloth in an approved container.
B. Install bleed hose into the approved container and open valve to bleed system pressure. Drain any fuel remaining in the gage into an approved container.
4. Disconnect Front Fuel Feed Hose at engine and body fuel feed pipes utilizing a backup wrench on fittings. Take care not to lose the seal and washer at the fuel rail. Remove bolt and pipe clamp on engine.
5. Examine the 0-ring seal and the white plastic [washer] retainer in the end of the fuel rail; determine that they are undamaged and in proper position for reuse. Examine the 0-ring on the body fuel feed pipe, making sure 0-ring is in proper position and undamaged for reuse. See Figure 2.
IMPORTANT: When the Front Fuel Feed hose/pipe fitting is disconnected at the Fuel Rail, there are two ways in which the retainer (white plastic washer) may be moved out of position: if the pipe is cocked while being withdrawn from the fuel rail, the retainer may be cocked or pulled slightly out. Also, the weight of the fuel in the fuel rail may push the retainer out of position when the fuel feed hose/pipe is withdrawn. If the new Front Fuel Feed Hose is installed without first ensuring the retainer is correctly positioned (square and fully seated), the connection may leak.
6. Obtain new Front Fuel Feed Hose (Service P/N 24570910). Install the new Front Fuel Feed Hose to the engine fuel rail and to the body fuel feed pipe fitting, ensuring hose is not kinked or twisted. Torque the pipe nut at the fuel rail to 30 N.m (22 lbs.ft.) and the hose fitting at the body pipe to 27 N.m (20 lbs.ft.), utilizing a backup wrench on fittings.
Reinstall bolt and pipe clamp, torquing bolt to 12 N.m (1 06 lbs.in.).
Ensure that there is at least 13 mm (1 /2 inch) clearance between the fuel feed hose and any sharp edges. Do likewise for the fuel return hose assembly.
7. Reinstall fuel tank filler cap and reconnect the negative battery cable. Reset clock and radio station preset buttons to owners choices noted at Step 2.
8. Start engine and check for possible fuel leaks and correct as required. Also check the fuel pressure connection for leaks.
9. Install a Campaign Identification Label.
CAMPAIGN IDENTIFICATION LABEL
Each label provides space to print the campaign number, and the five (5) digit dealer code of the dealer performing the campaign. insert this information with a typewriter or ball-point pen. When installing label, clean and dry the surface of the radiator support tie bar and apply the campaign label where ft is readily visible.
