The 1997 Buick LeSabre intake manifold bolt torque specifications is 45 pounds per square inch. The manifold bolts should be torqued in 15 pound intervals.
Correct torque on 2000 model : 18 Ft. lbs.- upper intake manifold [ plenum ].
what is the torque specificationfir the rockerarm bolt on 1991 Buick le Sabre v-6 3.8 liter
intake torque specs 2002 buik century
You did not mention if it was the intake to the cylinder head bolts (1993 buick lesabre 96 in-lbs)..... or ..... the intake upper to lower bolts ( 1993 buick 132 in -lbs) but i hope you will know wich you are looking at since there is a large difference in torqe.
What's wrong with it?
The lower intake manifold to cylinder head torque specification is 132 inch pounds. The upper plastic intake plenum to lower intake should be done in three steps 22 inch pounds, 44 inch pounds and thirdly 89 inch pounds. Be sure to follow the appropriate tightening sequence diagram.
replace the water heater inlet pipe on the intake manifold on a 3800
18436572, should be stamped on factory intake manifold
I'm pretty sure this is that same 3800 motor that gm uses in my mom's 2001 buick Le Sabre. Her intake was the fiberglass resin plastic and the torque specs are 89 INCH pounds. Make sure you use the right tightening sequence too. 89 inch pounds is for the upper intake or Plenum. 136 inch pounds is the torque specs for the lower intake
The intake manifold, head, and exhaust manifold must be removed to gain access to the gasket.
That should be the Oxygen Sensor
