MY VEHICLE HAS ONLY 50,000 MILES ON IT AND ALREADY HAS AN INTERNAL LEAK OF RADIATOR FLUID. THERE HAS BEEN NO LEAKAGE UNDER THE CAR FROM ANY HOSES OR COMPONENTS. MY ENGINE LIGHT HAS GONE ON NOW AND THE CAR IS SPUTTERING. I HAVE TAKEN THE CAR DOWN FOR REPAIR AND THEY STATE THAT THE PLASTIC INTAKE MANIFOLD HAS CRACKED CAUSING THE FLUID TO BE SUCKED OUT OF THE RADIATOR SYSTEM AND EVAPORATED THROUGH THE ENGINE. MY CAR HAS NOT CAUGHT FIRE, BUT ACCORDING TO THE INFORMATION ON THIS SITE, I SEE THAT MY CAR IS IN DANGER OF HAVING THAT HAPPEN. *NLM
WHILE DRIVING AT ANY SPEED AND NO WARNING THE VEHICLE STALLED AND WAS DIFFICULT TO RESTART. *NLM
THE INTAKE MANIFOLD CRACKED WHICH RESULTED IN COOLANT LEAKING INTO THE ENGINE AND CAUSED THE ENGINE TO SEIZE. THE PROBLEM CAUSED EXTENSIVE DAMAGE TO ENGINE, STARTER AND FLYWHEEL.*JB *TS

104V090000 · Fuel System, Gasoline:delivery
Feb 24, 2004
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE FUEL FROM THE LEAKING REGULATOR AND A MISTIMED SPARK CAN CAUSE A BACKFIRE.
Consequence & remedy
Consequence: THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
Remedy: DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080, OLDSMOBILE AT 1-800-630-6537, OR PONTIAC AT 1-800-620-7668.
