🔌 Function

⚠️ Common Signs of Failure

• Stretched or necked shank
• Damaged or corroded threads
• Loosening or pulled threads
• Cracking at the thread run-out
• Incorrect installed projection

🛠️ Service Notes

• Clean and chase the female thread before fitting so the stud can pull down square and to full depth
• Screw studs in with a proper stud installer or the double-nut method; gripping the plain shank with pliers or self-grips scores it and the nut will never seat or torque correctly afterwards
• Screw the stud home until it seats as the manual for your engine describes, and no further — a stud wound in hard to cure a slack thread will simply split the casting
• Renew studs that are stretched, necked, bent or corroded rather than reusing them; exhaust and manifold studs in particular are cheap next to the work of extracting a broken one
• Tighten the nuts to the torque figures and in the sequence given in the workshop manual for your engine, and where a stud passes into an oil or coolant space seal it as the manual specifies
