1996 Pontiac Bonneville SE 3.6 V6 from North America
Cooling system is an engineering fiasco and a money pit
Constant overheating and running hot.
Fluid leaks on the garage floor.
Broken water pump.
Upper manifold cracked and coolant leaked into engine.
If you prowl the Internet, you will find that this is a serious engineering problem with all Pontiac Bonnevilles. The upper manifold is plastic, and develops cracks and leaks. Since it is not a "safety" problem, Pontiac and the U.S. government are not going to force a recall. Caveat emptor.
It is no wonder GM is losing market share, it's the last year for Bonneville, and GM is considering eliminating the entire Pontiac line. Over 8,000 Bonneville owners have had similar problems with no help from General Motors.
Would you buy another car from this manufacturer? No
