Three problems related to engine failure have been reported for the 1999 Chevrolet Blazer. The most recently reported issues are listed below.
1999 Chevrolet Blazer with a v6 engine had a premature engine failure at 87k miles. A hair line crack was discovered in a cylinder using a dye test. The machinist who inspected the engine believes it was created as the result of the corrosive action of coolant used by gm. Chevrolet showed no interest in inspecting the engine. Without the aforementioned, I investigated myself, and can only conclude that a head bolt was not properly sealed during manufacturing, allowing coolant to penetrate the bolt area around the rear cylinder in question. This condition created a weakening of the cylinder wall over time causing the catastrophic failure. I've been communicating with Chevrolet for over two years with no success.
While driving 45 mph engine failed and security light stayed on.
While driving, vehicle experienced possible engine failure causing sudden loss of all power, engine, brakes, and power steering failed.
