The torque specification for all glow plugs is:
a 30 N-m (22 ft.lbs)

This torque must NOT be exceeded because increasing the torque beyond the specification will cause closing of the ring gap, which can lead to premature failure of the glow plug.




1 - Ring gap OK (arrow) approximately 0.5 mm (0.02 in.)

2 - Ring gap closed (arrow) after being over-torqued
