New Tool: Torque Limitied Glow Plug Socket

Discovered this 3/8 drive, torque limited glow plug socket on ID Parts and bought one.

Whether or not you have a torque wrench, this socket is well worth the money so you don't over torque the glow plugs.

I had just installed new glow plugs and hand guesstimated the torque, which I discovered was grossly under estimated.

After several days of driving, each plug was still seated but barely.

Re-torqued with this socket to an automatic 13 ft lbs.

Not sure how the internals work, but there's no way to over torque.

Too bad! Spec for my ALH head is 11 ft-lbs for the glow plugs. Not to worry; I bought a beam type and it works great.

Cheers,

According to NGK specs, 11 ft-lbs is right in the middle of recommended range.

13 is right in the ball park.

One should own a torque wrench.

A few different ones actually..........

Let's see:

• Glow plug Torque socket
• 10 to 250 inch pound (10 to 300 inch pound if you can find one)
• 10 to 150 foot pound

Most Inch pound torque wrenches do no go down to 11 to 13 Inch pounds accurately. All the suitable torque wrenches I found cost $150+ while the ID Parts tool is only $29.
