CAMPAIGN: LACK OF ADEQUATE SERVICE OR MAINTENANCE
SUBJECT: LACK OF ADEQUATE SERVICE OR MAINTENANCE
Models: 1984-88 Pontiac Fiero Models with 2.5L L4 Engines (RPO LR8)
TO: ALL GENERAL MOTORS DEALERS
THIS CAMPAIGN BULLETIN SUPPLEMENTS CAMPAIGN BULLETIN 8A05B DATED MARCH 1989 AND SUPERCEDES CAMPAIGN BULLETIN 8R14 DATED FEBRUARY 1989. DISCARD BULLETIN 8R14.
General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in 1984-88 Pontiac Fiero Model vehicles with 2.5L L4 engines (RPO LR8).
An interaction of the engine compartment environment in 1984-88 Pontiac Fieros and maintenance or service related factors results in the potential for engine compartment fires.
If combustible materials come in contact with the exhaust manifold, an engine compartment fire can result. Engine compartment fires can spread to the passenger compartment and cause injury to occupants.
To reduce the possibility of this condition occurring, all vehicles will have changes made in their underhood environment. Specifically, all vehicles will have a manifold barrier installed, a minor change to deck lid sealing, and a general inspection (and repair as necessary) of underhood fluid and wiring systems. Additionally, 1984-86 model year vehicles will have a new exhaust manifold installed to bring them up to 1987-88 specifications.
VEHICLES INVOLVED:
Involved are certain 1984-88 Pontiac Fiero Model vehicles with 2.5L L4 engines (RPO LR8) produced within the following VIN breakpoints:

NOTE: THE REMAINING STEPS BELOW ARE INSPECTION ITEMS. IT IS IMPERATIVE THAT CARE BE EXERCISED IN INSPECTION. THE PARTICULAR ITEMS HAVE BEEN CHOSEN DUE TO THEIR POTENTIAL ASSOCIATION WITH UNDERHOOD FIRE. SEE THE NOTES ON EACH STEP FOR THE TYPES OF REPAIRS AUTHORIZED.
PLEASE NOTIFY YOUR CUSTOMER OF ANY ISSUES NOT FIXED IN YOUR INSPECTION WHICH WILL BE HIS/HER RESPONSIBILITY.
ANY ISSUES NOT SPECIFICALLY AUTHORIZED IN THIS BULLETIN MAY BE DISCUSSED WITH YOUR APPROPRIATE BDC CONTACT PERSON WITH SERVICE RESPONSIBILITY.
2. INSPECT COOLING SYSTEM
a. Visual check of coolant level. Adding needed coolant to specified level and/or diagnostic procedure will be authorized if coolant loss is determined to be a chronic problem. NOTE: With engine cold, perform a pressurized leak
NOTE: With engine cold, perform a pressurized leak test as described in 1986 Fiero Service Manual, Section 6B-14, 15.
b. Visually inspect for significant leaks. Repairs are authorized for external coolant leaks from any engine compartment area, specifically thermostat housing, water pump, coolant hoses and connectors in engine compartment.
c. Visually inspect for signs of coolant hose wear or aging. Replacement of of damaged hoses is authorized.
d. Perform a function check of cooling fan. Replacement of relay, coolant switch, wiring or fan is authorized to make functional.
3. INSPECT EXHAUST SYSTEM
a. Observe for any significant leaks (vehicle running). Repairs are auth- orized for any leaks forward of the catalytic converter. Also repairs should be made if any irregularity in manifold or front pipe prevents proper installation of the new shield.
b. Visually inspect for presence of appropriate heat shields. Repair or replacement will be authorized for starter shield, converter shield, muffler shield, or bulkhead shields. See Illustration F and G for correct configurations.
4. INSPECT LUBRICATION SYSTEM
a. Visually inspect for indications of significant oil leakage. Repairs seepage will not be authorized, only areas with significant leakage. Specifically, rocker cover gasket repair or PCV breather are authorized. Oil pan or filter leaks are not normally covered.
b. Visually verify update to 4 litres system. Vehicles should all be equipped with the larger oil filter (PF51 style). Replacement of the filter is authorized if vehicle was not previously retrofit.
c. Check oil level. Make up oil authorized for vehicles 1 litre or more low.
5. INSPECT FUEL SYSTEM
a. Visually inspect for signs of leakage inside engine campartment. Repairs are authorized for retorque, new fitting, or hose replacement.
b. Visually inspect evaporative emission system for integrity of harness connections. Reinstallation of harness authorized if necessary. Tampered systems to be replaced only if vapour lines were left open (presenting some fire risk). All emission discrepancies should be noted in writing to the owner and noted on the repair order.
6. INSPECT TRANSMISSION OIL COOLER
a. Visually inspect for signs of oil cooler hose leakage near transmission. Repairs are authorized for hose degradation or fitting tighten/replace.
7. INSPECT IGNITION SYSTEM
a. Visually inspect for proper spark plug wire routing. Rerouting authorized if required and replacement of spark plug wire retainer clips only.
8. INSPECT ENGINE COMPARTMENT WIRING
a. Visually inspect for correct routing of engine wiring harness in vicinity of exhaust manifold. Reroute and clip as necessary.
b. Visually inspect for correct battery cable routing. Reroute and clip if required.
c. Visually inspect for any obvious chafing/wear on starting/charging circuit wiring. Wire, conduit or retainer replacement authorized if necessary.
9. VISUALLY INSPECT FOR ANY COMBUSTIBLE MATERIALS HANGING LOOSE IN FRONT OF ENGINE COMPARTMENT. (e.g. conduit, insulation) Remove as required.
10. Install rear engine compartment lid and left side grille panel.
NOTE THAT COMPONENTS ON THE BULKHEAD WILL NOW BE BARELY VISIBLE FROM OUTSIDE THE VEHICLE WITH THE ENGINE COMPARTMENT LID CLOSED. THIS CHANGE INCREASES AIR FLOW THROUGH THE ENGINE COMPARTMENT. SHOULD YOUR CUSTOMER WISH, THE VISIBLE BULKHEAD COMPONENTS MAY BE SPRAYED FLAT BLACK.
INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL
Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.
