1996 Buick Regal Engine cooling Problems

“I bought a used car in boardman, ohio area and I now have a 1490.00 repair bill after salesman told me it was checked out. They replaced a burned out bulb with another burned out bulb which I can prove. I need help to stop this practice.”

“Buick Regal 1996.engine and engine cooling:cooling system hortly after just 72,000 miles, a leak developed near the upper intake manifold, causing excessive coolant loss (up to 1 gallon per week). I believe this to be a saftey hazard resulting from a design flaw. The owner's manual includes several warnings that coolant contains ethylene glycol that will burn if it comes in contact with hot engine parts. I am also concerned this problem may have caused engine damage that will manifest itself later. …”

“My 1996 Buick Regal has had two intake manifold gasket failures--one at 52,000 miles, and the most recent, at 111,000 miles. In the first instance, the local Buick dealership refunded half my money of the cost of the $607 repairs because they agreed that it was highly unusual for a gasket to fail at such low mileage. My son, who did the most recent repai andr is a materials science engineer, inspected the most recent failure and found several places on the gasket where it was deformed and had let antifreeze escape. His opinion was that it was badly designed, with inferior materials.”

“Vehicle back fire through the intake and smoke rolls out from under the hood when trying to start the vehicle, normally start good after sitting over night, but go to start it again it will back fire or the engine idle is very erratic before it will smooth out. I replace spark plug, spark plug wires, cam sensor, pcv valve, fuel filter check battery connection.”

“On engine start, loud explosion in engine compartment. Inspection reveled engine cover broken, upper intake manifold (plenum) split in two pieces. Smell of gas, broken vacuum and fuel lines. Must replace upper intake manifold, fuel rail, 2 injectors, various lines. Old parts are available.”
