What is a torque pattern?
Bolt tightening sequences are when an arrange of bolts are tightened in a pattern to the required torque. The sequence the bolts are tightened is a symmetrical pattern to reduce the amount of pre-load lost in a bolt, as a result of elastic interactions. Torque is normally applied to a bolt using a torque wrench.
Do you need to torque exhaust manifold?
Technically, it’s only necessary to tighten the manifold fasteners correctly. Some experienced mechanics can do that without a torque wrench.
How do I make a intake manifold gasket?
What are intake gaskets made of?
Typically made from aluminized steel coated in a carbon-based rubber compound, the intake manifold gasket seals the intake manifold to the engine. High-quality intake manifold gaskets, such as Fel-Pro ®, are constructed as one-piece with reinforced edges and linings around each port or runner opening.
What should exhaust clamps be torqued to?
Band clamps are usually tightened to 40ft-lbs and U-bolt clamps should be approximately 30-35ft-lbs. You want the U-bolt to uniformly pull down the larger slip-on pipe, without deforming the inside pipe. Re-check the fasteners after 25-50miles of operation and retighten as needed.
What grade bolts should I use for exhaust manifold?
You don’t need seriously strong bolts just to fasten manifolds to the heads. Grade 5 is fine.
How do you torque exhaust manifold studs?
Use a small amount of anti-seize on the exposed threads that will be in contact with the nut. Install the exhaust manifold gasket and exhaust manifold. Install the washers and 12-point nuts and torque the nuts to 40 ft-lbs. Tighten in a sequence working from the inside to the outside as shown at right.
