Question about Cars & Trucks
That would not cause the engine to get overheated. It may be too late to save your engine, but check if you have coolant loss and brown sludge on the oil dipstick, or if under the oil fill cap there is a milky brown substance. This is evidence of coolant getting into the oil. This engine in LeSabres has a common problem of intake manifold gasket failure, leading to loss of coolant that winds up in the cylinders and into the oil. If not driven much or if the engine did not get too hot, the cylinder heads and head gaskets may not have been ruined, but if overheated badly, the engine may be a total loss.
The intake on the engine is two parts: an upper intake manifold that is plastic (and just waiting to fail-many owners have had to replace this) and an aluminum lower intake manifold. The gaskets under the lower manifold are the ones that develop leaks. Because GM used inferior factory gaskets (also made of plastic) as a cost-cutting measure. They took a very good engine, well known for durability, and shaved costs with inferior gasket material-go figure.

SOURCE: Leaking brake fluid
It is the proportioning valve. It was only available at the dealerships repair center for me. $70.28. its a very common problem. and a pain in the **** getting the old one off. i found you cuz im trying to find out how to get the brake lines off. a 10 mm open end wrench does not work. going to try 100 mm line wrench in a minute. wish me luck. by the way there are 6 lines running to it and 2 bolts hold it to the firewall

if you can see a good amount of wet brake fluid between the brake master cylinder and the brake booster. and you have been adding fliud often,you could have a bad master cylinder. it has to be replaced not rebuilt. you however may have a far more common problem, a rusted through brake line.have someone pump the brake pedal, than look under the car for a brake fluid leak ,repair as needed. than bleed the brakes for a good hard brake pedal
good luck chris

Yeah on that vehicle there is a 90 degree plastic elbow that goes from the belt tensioner to the intake manifold and on both ends there are O-rings. Definitely need to repair this as soon as possible. Not sure your technical abilities but you would need to remove the serpentine belt and alternator and a bracket if I'm not mistaken. Usually takes me about 45 minutes to repair but I have been doing it for awhile. Good luck and Happy wrenching!!!

pipe going to the fire wall is usualy the cabin heater. for the time being there should be 2 hoses going to the fire wall coolant in/out. remove them from the pipe on the fire wall and blank them off or if the hose is split replace them. it could be the heater core but that usualy leaks into the cab.
