# RTV SEALER/GASKET ELIMINATOR DESCRIPTION

THIS BULLETIN IS A FOLLOW-UP TO TWO (2) PREVIOUS BULLETINS: THERE ARE TWO (2) SEALERS USED TO SEAL GM ENGINES. THE FIRST IS RTV (ROOM TEMPERATURE VULCANIZING) WHICH IS USED WHERE A NON-RIGID PART IS ASSEMBLED TO A CAST OR RIGID PART SUCH AS ROCKER COVERS, OIL PANS, ETC THE SECOND IS GASKET ELIMINATOR, AN ANAEROBIC MATERIAL (CURES IN THE ABSENCE OF AIR) WHICH IS USED WHERE TWO (2) RIGID PARTS ARE ASSEMBLED TOGETHER, SUCH AS TIMING CASE COVERS. WHEN TWO (2) RIGID PARTS ARE DISASSEMBLED AND NO GASKET OR SEALER IS READILY NOTICEABLE IT IS SEALED WITH GASKET ELIMINATOR. WHEN ASSEMBLYING PARTS, USE THE PREFERRED MATERIAL. DON'T USE RTV TO SEAL TOGETHER TWO (2) RIGID PARTS AND DON'T USE GASKET ELIMINATOR ON STAMPED PARTS SUCH AS ROCKER COVERS. DIRECTIONS FOR USE OF RTV: 1. WHEN SEPARATING COMPONENTS SEALED WITH RTV, USE A RUBBER MALLET AND "BUMP" THE PART SIDEWAYS TO SHEAR THE RTV SEAL. "BUMPING" SHOULD BE DONE AT BENDS OR REINFORCED AREAS TO PREVENT DISTORTION OF PARTS. RTV IS WEAKER IN SHEAR (LATERAL) STRENGTH THAN IN TENSILE (VERTICAL) STRENGTH. ATTEMPTING TO PRY OR PULL COMPONENTS APART MAY RESULT IN DAMAGE TO THE PART. 2. SURFACES TO BE RESEALED MUST BE CLAN AND DRY. REMOVE ALL TRACES OF OIL AND RTV. CLEAN WITH A CHLORINATED SOLVENT SUCH AS CARBURETOR SPRAY CLEANER. DON'T USE PETROLEUM CLEANERS SUCH AS MINERAL SPIRITS; THEY LEAVE A FILM ONTO WHICH RTV WON'T STICK. 3. CUT THE TUBE OPENING TO APPROXIMATELY 1/8" DIAMETER. 4. APPLY RTV TO ONE OF THE CLEAN SURFACES. CIRCLE ALL BOLT HOLES. 5. ASSEMBLE WHILE RTV IS STILL WET (WITHIN 3 MINUTES). DON'T WAIT FOR RTV TO SKIN OVER. 6. TORQUE BOLTS TO SPECS. DON'T OVER TORQUE. 7. RTV WILL SKIN OVER IN 15 MINUTES SUFFICIENTLY TO ALLOW FOR TESTING AND LIMITED OPERATION OF VEHICLE. STOP ENGINE AND ALLOW RTV TO CURE FOR APPROXIMATELY 1 HOUR BEFORE PLACING VEHICLE IN SERVICE. DON'T USE RTV WHEN EXTREME TEMPERATURES ARE EXPECTED, E.G. EXHAUST MANIFOLD, HEAD GASKET OR WHERE GASKET ELIMINATOR IS SPECIFIED. NOTICE: HIGHER TEMPERATURE RESISTANT COMPOUNDS ARE VISUALLY RED DUE TO THE ADDITION OF IRON OXIDE. DIRECTIONS FOR USE OF GASKET ELIMINATOR: 1. CLEAN SURFACES TO BE RESEALED WITH A CHLORINATED SOLVENT TO REMOVE ALL OIL, GREASE AND OLD MATERIAL. 2. APPLY A CONTINUOUS BEAD OF GASKET ELIMINATOR TO ONE FLANGE. 3. SPREAD BEAD EVENLY WITH YOUR FINGER TO GET A UNIFORM COATING ON THE COMPLETE FLANGE. 4. ASSEMBLE PARTS IN THE NORMAL MANNER AND TORQUE TO SPECS. 5. VEHICLE CAN BE OPERATED AFTER COMPLETION OF ASSEMBLY. NO NEED TO WAIT FOR GASKET ELIMINATOR TO CURE. NOTICE: THE USEFUL SHELF LIFE OF MOST RTV AND GASKET ELIMINATOR PRODUCTS IS ONE (1) YEAR. DON'T USE GASKET ELIMINATOR WHERE RTV IS RECOMMENDED. THE KEY TO SATISFACTION WITH RTV AND GASKET ELIMINATORS IS FOLLOWING THE DIRECTIONS AND USING WHERE SPECIFIED. DON'T CUT THE PROCEDURE SHORT OR A LEAK MAY RESULT. RTV'S DIFFER IN PERFORMANCE. FOR BEST RESULTS, USE PRODUCTS ONLY GM RTV OR GASKET ELIMINATOR FROM THE FOLLOWING LISTS: SEALANT TYPE WDDGM P/N COLOR SIZE AND CONTAINER TYPE RTV 1052914 BLACK 10 OUNCE CARTRIDGE RTV 1052917 BLACK 3 OUNCE TUBE RTV 1052915 BLACK 10 OUNCE CARTRIDGE RTV 1052366 RED 3 OUNCE TUBE GSK ELIM.(ANAE) 1052357 ORANGE 6 ML.

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.
