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.
Its at the rear of the engine in the intake manifold. Take the 2 bolts off that hold it and clean all of the carbon before installing the new one.
You must remove the fuel tank in order to access the pump. Once you have the tank out, it is just a matter of removing the pump and installing the new one.
Manifold Absolute Pressure/Barometric Pressure Sensor
replace the water heater inlet pipe on the intake manifold on a 3800
Hook it to a battery charger.
Manifold ait temperature sensor circuit. Year and model?
The Coolant Temperature Sensor on a 1993 & 1994 Buick LeSabre is located on driver's side of the car under the throttle body, It is screwed into the lower intake manifold. You cannot see it without first removing the throttle body since it is hidden under it. An electronic plug is clipped to the the end of the CTS.
Exactly the same except the Lucerne has the improved metal manifold pipe. I think the 04 and 05 LeSabre also replaced the plastic pipe with metal.
The starter on a 92 Buick LeSabre is replaced by disconnecting the battery, removing the retaining bolts, and lowering the starter. The wiring harness can then be disconnected and a new starter installed.
Struts on a 1998 Buick LeSabre are changed by jacking the vehicle up, removing the wheel, and unbolting the strut. It can then be pulled from its mounts and a new strut put in place.
The IAT sensor is located on the intake manifold air cleaning housing or air duct.
Most likely a cracked intake manifold.
The thermostat on a 1992 LeSabre should be inside of the top radiator hose inlet. You can easily change it by removing the top hose and water inlet.
It should be located on the intake manifold by the distibutorless ignition module. On my 92 Lesabre it is located near the plugs at the back of the motor. On my 94 LeSabre it is located on the front/driver's side of the engine. There is a 4-wire connector on the top and it is mounted by two bolts on a flange. About 2" in diameter, 4" high.
The license plate bulb on a 1998 Buick LeSabre is replaced by removing the retaining screws and disconnecting the wiring harness. The bulb can then be twisted from the socket and a new bulb installed.
The side marker bulbs on a 2002 Buick LeSabre are replaced by removing the retaining screws and disconnecting the wiring harness. The old bulb can then be removed and a new bulb put in its place.
In the rear, of the engine, right in the center, on top of the exhaust manifold. Right where the exhaust meets the engine block.
The way that replace a window regulator in a 2003 Buick LeSabre front drive side is by removing the door panel. Next, disconnect the electrical connector on the regulator and replace.
Usally on the rear manifold rear top of engine. You should be able to see the sensor wire from the brain box going out to it.
Most EGR valves are located on the intake manifold with a vacuum line attached. Most are held on with two bolts.
The catalytic converter on a 1994 Buick LeSabre can be removed to be replaced. It cannot be removed permanently from the vehicle. Removing the catalytic converter will cause the vehicle to not run properly because there are oxygen sensors attached to it that the car needs. Also, removing the catalytic converter permanently may violate state laws against pollution in some states.
Serious. On the intake manifold a leak sucking in of air will cause a lean running condition generating excessive heat if the computer is unable to adjust by adding more gas to the mixture.
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.
On almost every engine it is in the side of the valve cover. It is a 2 to 3 inch long plastic part that has a 3/8ths hose that connects to the intake manifold.
