Is the head bolt torque sequence the same for all engines?
Is the head bolt torque sequence the same for all engines?
Head bolt torque sequence, however, generally remains constant for a given engine. To give you a quick reference of torque sequences, OnAllCylinders’ Lori Sams has created a series of infographics for different engine makes. Today, we’ll look at cylinder head torque sequences for General Motors L8 and V8 engines.
What do I need to know about cylinder head torque?
Check with the manufacturer when using aftermarket fasteners as the specifications will vary. These torque values are usually based on oiled fasteners. Lubricate the threads and underside of the bolt head with motor oil or aftermarket lubricant.
What to know about torque to yield fasteners?
Make sure your existing bolt aren’t torque-to-yield (TTY) — this type of fastener is designed to stretch and cannot be reused. Check bolts in a set against one another to ensure none are stretched or deformed — damaged fasteners must be thrown out or replaced. When using stock fasteners, check your service manual for proper torque specs.
What do you need to know about cylinder head fasteners?
You’ll need to check that your cylinder head fasteners don’t bottom out in blind holes. Use hardened steel washers when installing aluminum cylinder heads. This will prevent galling of the soft aluminum. Check the accuracy of your torque wrench and recalibrate, if necessary, before bolting down your cylinder heads.

Do you need a cheat sheet for torque sequence?
From fixing a leaking push-rod tube, to slapping in some 94mm pistons and aftermarket heads, eventually the heads will be removed and need to be re-torqued. We’ve created this easy-to-use torque sequence cheat sheet. Save this to your phone, computer, or print it out for use in the shop!
What are cylinder head torque specs?
Cylinder head bolt torque is 35 Nm or 26ft lbs plus 180 degrees. See picture for sequence. All bolts must be torqued to 35 prior to additional degrees.
What is the torque on the cylinder head bolts?
torque the cylinder head bolts. Torque: 30 Nm (22 ft-lbs).
What is the head bolt torque?
Head Bolt Torque Head bolt torque refers to the amount of rotational force that must be applied to the cylinder head bolts for a safe and secure connection either to the engine block or another cylinder head depending upon the engine. After the desired torque is reached, some bolts then require further rotation of a few degrees.
What is the torque of a cylinder?
Torque Engine torque is produced on the crankshaft by the cylinder pressure pushing on the piston during the power stroke. In an IC, engine torque is produced at the crankshaft as explained below. The torque that is applied to the crankshaft is called “indicated torque Ti.”
