Your car may fall under the class action suit being settled by GM due to its requirement of the use of Dexcool. It forms a brown "sludge" that causes more damage to the car. My head gasket has had to be replaced twice in less than 3 years. Search for GM and Dexcool and see what you can find about the suit. Best of luck! Another possibility is that the fan is not running while the car is on. This can be fixed easily with a hot-wire under the hood of the car that bypasses electrical systems and makes sure the fan is blowing at all times when the car is on.

As with any car, low coolant will cause this car to overheat. Common areas of coolant lose are the water pump or intake manifold gaskets.

This will cause an overheat.- TechJK -----------------------------------------------------------

What size engine is in a 2001 grand am se?

LA1 3.4 L V6 The LA1 3400 ("E-code") was a bored-out version of the LG8.It kept the OHV layout of the previous engine and appeared in a car for the first time in the 1999 Pontiac Grand Am and Oldsmobile Alero.A 92 mm (3.6 in) bore with the same 84 mm (3.3 in) stroke brought the displacement to 3.4 L (3350 cc) The 3.4 L engine is known to have intake manifold gasket problems, much like all other GM v6's. This is known to cause engine damage if the owner of the car neglects to change the gaskets- so car companies have released gaskets that correct this problem for good, such as :# 1996 Chevrolet Lumina APV/Pontiac Trans Sport/Oldsmobile Silhouette # 1997-2004 Chevrolet Venture/Pontiac Montana/Pontiac Trans Sport/Oldsmobile Silhouette # 1999-2004 Oldsmobile Alero GL/GLS # 1999-2005 Pontiac Grand Am SE/GT # 2002-2005 Pontiac Aztek/Buick Rendezvous # 2000-2005 Chevrolet Impala # 2000-2005 Chevrolet Monte Carlo


When a fuel pressure regulator leaks on your 1999 Oldsmobile alero can it cause the fuel pump to work intermittently?

I doubt it. I have a 01 Alero that had to have a new fuel pump at about 100,000. If you have a leaking regulator, you need to replace it. It is a fire hazard. The symptoms for the bad fuel pump were normal function then it would just stop working. When it cooled down it would work again.
