CAMPAIGN:FUEL TANK PLASTIC RESERVOIR ATTACHMENT
Subject: PRODUCT CAMPAIGN 95-C-35 - FUEL TANK SEAL AND COVER
Model and Year: 1995 S/T 4-DOOR UTILITIES
To: All Chevrolet/Geo Dealers
General Motors has determined that certain early production 1995 4-door Blazers have a condition which could result in fuel leakage in certain high speed frontal collisions. If one of these vehicles, with a substantial amount of fuel in the tank, were involved in a frontal collision at speeds higher than those specified by Federal safety standards, a hole in the bottom of the tank could occur resulting in fuel leakage.
To correct this condition, dealers are to apply a seal and cover to the exterior of the tank bottom.
VEHICLES INVOLVED
Involved are certain 1995 Chevrolet 4-Door Blazers built within the following VIN breakpoints:
PLANT YEAR MODEL PLANT CODE FROM THROUGH ----------------------------------------------------------------- 1995 Blazer Linden "K" SK100001 SK179987 1995 Blazer Moraine "2" S2100001 S2165667
Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
PARTS INFORMATION
A preshipment of parts will be sent to involved dealers the week of May 1, 1995. Preshipment parts will be charged to the dealers' open parts account.
Additional parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a "C.I.O." order with no special instruction code, but on an advise code (2) All Goodwrench parts system test dealers should order on a 'VIP" order.

SERVICE PROCEDURE - Figures referenced
1. Disconnect negative battery cable from battery after noting all electronic device settings.
2. Raise vehicle on hoist and support with safety stands.
3. Remove steel shields from around fuel tank, if equipped (Figure 1).
4. Using a transmission jack, support rear section of fuel tank (use suitable padding between fuel tank and jack. Figure 4).
5. Loosen rear fuel tank strap (Figure 2, Item 3) in order to swing side rail protector (Figure 2, Item 2) away from bottom of fuel tank.
6. Secure side rail protector in the "swung out" position.
7. Use a "pre-sol" solution (Dupont 3919 or equivalent) to remove any dirt and grime from fuel tank area where seal and cover will be applied (Figure 3). The cleaning solution used must not leave any only residue or film on the surface of the tank.
NOTICE: Prior to applying fuel tank seal and cover in step 8 and 9. Be certain the surface is completely clean and dry.
NOTICE: The "Butyl Mastic" seal and cover must be applied above 600 Fahrenheit.
8. Take the "Butyl Mastic" fuel tank seal with the thin aluminum foil looking back and peel approximately one inch of the protective paper away from the adhesive material.
9. Align exposed adhesive side of seal along radius bend line where fuel tank strap channel radius is (Figure 4) and apply seal to fuel tank. Carefully remove remaining protective paper from seal and apply seal firmly to bottom of fuel tank. Smooth out the seal evenly onto the metal surface. Keep side edges of the seal in parallel with fuel tank sides (make sure seal's edges do not go beyond radius of the other sides).
10. Take "Butyl Mastic" cover with thicker aluminum looking sheet backing and peal back approximately one inch of the protective paper from the adhesive material.
11. Align adhesive side of cover along the same radius bend line on top of the seal (Figure 4) that was applied in step 9 above. Remove remaining protective paper from cover and apply cover firmly over top of seal, smoothing it out evenly.
12. Relocate fuel tank side rail protector (be certain to center rear protector tabs over the tank flange, Figure 2, Item 2). Reposition fuel tank strap and insulator. Torque fuel tank strap bolt to 34 Nm (25 lb. Ft.) (Figure 2, Item 4).
13. Remove transmission jack from rear of fuel tank. Reinstall fuel tank steel shield to vehicle, if equipped (Figure 1, Item 2).
14. Lower vehicle from hoist and reconnect negative battery cable. Reset all electronic equipment to settings noted in step 1.
15. Install Campaign Identification Label.
16. Fill fuel tank and wash before returning vehicle to owner (this is to be done only once for vehicles involved in 95-C-31, 95-C-33, 95-C-34 and 95-C-35).
CAMPAIGN IDENTIFICATION LABEL
Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label". Each label provides a space to include the campaign number and the five (5) digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or a ball point pen.
Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be visible when the vehicle is brought in for periodic servicing by the owner. Additional "Campaign Identification Labels" can be obtained from DAC.
Apply "Campaign Identification Label" only on a clean, dry surface.

Dear Chevrolet Blazer Owner:
Your complete satisfaction with your 1995 Chevrolet Blazer is most important to us. Throughout a production run enhancements typically are made to our vehicles as part of our continuous improvement process. This letter outlines one of these enhancements which Chevrolet would like to make available to you at no charge.
Federal Motor Vehicle Safety Standards require vehicles sold in the U.S. to be able to pass specified crash tests with very little fuel leakage, if any. Your 1995 Blazer surpasses the requirements of these safety standards. However, recent crash tests revealed that if a four door Blazer with a substantial amount of fuel in the tank were involved in a frontal collision at speeds higher than those specified by the federal standard, a hole in the tank could occur resulting in fuel leakage. While fuel leakage is always possible in high speed crashes, we were not satisfied with this performance. Consequently, we have developed a seal and cover for the exterior of your vehicle's fuel tank which will avoid this fuel leakage. Applying this seal and cover can be done without removing or disassembling your Blazer's fuel system.
Instructions for performing this service have been sent to your Chevrolet dealer. This enhancement will be made to your vehicle at no charge to you. Please contact your Chevrolet dealer to arrange a convenient appointment and ensure the proper parts are available to complete this service. The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in installing this enhancement in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.
Your complete satisfaction with your 1995 Chevrolet Blazer is important to us and we encourage you to see your Chevrolet dealer for this modification.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
