2004 Buick LeSabre Limited 4dr Sedan (3.8L 6cyl 4A)
LeSabre's 2000-2004 are made with a
phenolic resin intake maniford that
warps and leaks antifreeze into the
engine's cylinders - basically blowing
superheated steam into the combustion
chambers. The factory-recall fix (put
locktight on 3 bolts) doesn't work.
According to a factory trained
mechanic, many engines have had to be
replaced because of this cheap
construction. Also, "permanently
lubricated" tie-rods wear prematurely
and have to be replaced at low milage.
Plastic window grips on electric
windows break easily.
Battery under the back seat saves it
from engine heat.
