2000 3.8 Lower intake manifold (manifold to cylinder head) 1st step is 44 inch pounds, 2nd step is 89 inch pounds. This must be done in sequence.
35 ft pounds
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.
The 1999 Pontiac cylinder head gasket bolt torque specification is 160 pounds. The intake manifold bolt torque specification is 90 pounds.
lower intake is 115 in pounds upper is 18 ft pounds
the torque specs for the intake manifold are 115 inch pounds inch pounds to newton meter = mutiply .113 by the number of inch pounds aprox. 9.5 foot pounds
30 ft pounds
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.
The 350 cubic inch Chevrolet intake manifold bolts have a torque specification of Haiti pounds psi. The bolts should be torqued at 40 pound intervals.
25 to30 foot pounds
Dunno if it's any help, but on my 93 model it was 125 INCH pounds. No sequence was listed so I criss-crossed in an alternating pattern.
The torque specifications, for a 4.3 liter engine manifold, is 45 pounds per square inch. Torque the manifold bolts in 15 pound intervals.
the haynes book states 89 in pounds
There is no torque spec for the air filter --it sits in its housing which snaps open and closed.The intake manifold torque specs are 89 inch pounds (7.5 ft.lbs.), that is for both the upper and lower intake.
Carefully tighten the bolts in a crisscross pattern to 45 inch pounds. Then re-tighten them to 83 inch pounds.
Haynes manual says 115 inch pounds- Start from center of intake using a criss-cross pattern, working your way to ends of intake.
Torque for the 300 6 intake and exhaust manifolds is 28 to 32 foot pounds
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
Intake Manifold (Cast Iron Heads) Non- Hardening Sealer 30 ft-lbs.
AnswerIf this is the V-6, then you must have a common problem...lower intake leaks coolant.The torque spec for the lower manifold is:First pass: 60 inch poundsSecond pass: 110 inch poundsLast (outer bolts only): 18 foot poundsUpper intake is a total 88 inch pounds in at least two steps.Randy
it's pretty easy. However because of how vital it is to follow manufacturers specs on torquing the manifold I would sugest getting a manual. Expect to spend between 4 and 6 hours on it. Remove everything from the intake manifold be sure to label everything carefully. Drain the coolant. Remove the intake bolts a1/4 turn at a time until they are all evenly removed. Clean off all traces of gasket material. The joints need to be spotless. It is imperative to not damage the mating surfaces. When you reinstall everything be sure to replace the gaskets in the same direction they came off. Re torque the manifold in three steps 15 foot pounds,then 25, ending at 35 foot pounds. The sequence is essentially middle right, middle left, rear left, rear right, front left, front right. It is more intricate than that which is why i recommend securing a manual.
Incorrect torque pounds, or incorrect sequence of torque,improper gasket installation, foreign matter not allow gasket to properly seal or warped intake manifold or warped block

The intake manifold gasket is located between the manifold and the engine block, and prevents leaks between the two surfaces. Follow the below steps to replace the intake manifold gasket on 2003 Ford Ranger. 1) Disconnect the cable to the negative terminal of the battery and remove all hardware and wiring that connects to the intake manifold. Now disconnect the throttle position sensor and the EGR valve, located adjacent to the intake manifold. 2) Remove the fuel lines from their respective connections to the fuel injectors. Plug the fuel lines to minimize fuel spilling. Disconnect the intake manifold runner control cable from the manifold. 3) Label the spark plug wires and pull from the boot to remove from their corresponding spark plugs. The spark plug wires must later be connected to the same plugs in order for the cylinders to fire in the correct order. 4) Remove the bolts that hold the intake manifold to the engine block, and remove the manifold. Pry the intake manifold gasket from the block with a flat-head screwdriver. Clean the top mating edge of the engine block thoroughly. The surface where the new intake manifold gasket will rest must be smooth and free of debris. 5) Apply sealant to the gasket surfaces and place it on the mating edge of the engine block. Position the new intake manifold so that it aligns exactly with the cylinder flanges of the engine block. Bolt the intake manifold to the engine block. Tighten the bolts to 22 foot-pounds with a torque wrench. 6) Reconnect the spark plug wires with their corresponding spark plugs. Pull the boots over the spark plugs. Replace all removed parts in their original positions. Reattach all of the fuel lines to the fuel rails and fuel injectors. Reconnect all electrical wiring to its respective part. 7) Connect the cable to the negative terminal of the battery. Start the engine and let it idle for about ten minutes. Check for leaks around the new intake manifold gasket.
