Question about 1997 Buick LeSabre

1 Answer

1996 Buick Le Sabre. 3.9 v/6 Check engine light came on and found out plastic intake manifold was cracked. Replaced the intake and for a few days light was off. Then the same check engine light came back on. Car surges sometimes and will almost die while idling. It runs ok, most of the time, but check engine light stays on. Got any ideas?

Coolant leaking in and around the intake manifold as well as the under carriage of that same part I think. Outake? I know that the part that attaches to the manifold appears to be metal but the manifold...


The plastic piece is the upper intake manifold. The metal part is the lower intake manifold. Sometimes the gaskets go bad between the upper and lower intake manifolds. But usually the upper intake manifold is cracked and needs replaced.

1999 buick century coolant on top of intake manifold no engine lights on


Carefully check all hoses & clamps. If leak/seepage not found then check for leak along the intake manifold - the manifold gasket could be leaking and this is quite common.

Coolant leak at intake 1994 Buick LeSabre 3.8 ltr


There are several areas of possible leakage. One is the hose and plastic outlet from the intake manifold on the passenger side of the engine. The hose runs low, underneath the alternator. The plastic outlet cracks, the hose gets old, the clamps on the hose can also be loose. The replacement outlet from the dealer is steel, not plastic.
Another possibility for leakage is on the driver's side of the intake manifold. Underneath the air inlet is a metal cover on the end of the intake manifold. This covers the coolant passages at the end of the intake. Mine was oozing antifreeze..you don't have to pull the intake to replace this.
The other place for leaks is the intake itself..requiring removal of the intake. I've done this...I don't think it is that bad of a job. However, if you put in a new intake, don't forget to put in a pcv valve..it fits under a small cover at the right rear of the intake manifold.
