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