NHTSA Complaint #718363 — 1995 CHEVROLET S10

ON AND ABOUT APRIL 15TH OF 1999, I HAD MY OIL CHANGED AT MY SERVICE STATION. THEY TOLD ME THAT I WAS LOW ON COOLANT AND THEY SPOTTED A LEAK ON THE OUTSIDE OF THE CYLINDER HEAD. THIS LEAK WAS VERY SMALL AND ALMOST UN-NOTICEABLE. I HAD THEM FILL THE COOLANT TANK AND CONTINUED TO MONITOR THE PROBLEM. I CONTACTED MY CHEVROLET DEALER AND WAS TOLD THAT THE TRUCK HAD JUST GONE OUT OF WARRANTY. SINCE THAT TIME THE LEAKING PROBLEM HAS CONTINUED TO GET WORSE. I HAVE BEEN ABLE TO FIND OUT THAT THERE HAVE BEEN "MANY" REPORTS OF THIS SAME PROBLEM. I WORK FOR A NAPA AUTO PARTS STORE AND OUR MACHINE SHOP IS A MEMBER OF A NATIONAL COMPANY THAT HAS SPECIFICATION STATS FOR ENGINES AND THEY HAVE A BULLETIN ISSUED ON MY PROBLEM WHICH STATES IT IS A CASTING PROBLEM THAT WAS CAUSED WHEN THE CYLINDER HEADS WERE MANUFACTURED. I REALLY DO BELIEVE THAT GM KNOWS ABOUT THIS AND SHOULD MAKE GOOD FOR REPAIRS. IT HAS NOTHING TO DO WITH MAINTENANCE. IT IS A FLAW IN THE CASTING OF THE HEAD!*AK
