Ford 3930 glow plugs?

[Jason280]

I have a mid 90's (I believe) Ford 3930, and trying to figure out whether it has glow plugs or not...and if it does, how are they activated? I've tried a few google searches, but I've gotten some conflicting information.

Any ideas?

Mo glow plugs, but it should have a manifold heater/thermostart in the intake. It is activated by turning the key to just before start for 10-30 seconds and then to the start position. There is no indicator light to tell you if it is on however.
It is located at the front inside of the intake. If you activate it and is working, you should feel that portion of the intake getting 'hot'.
Also, it will start easier of course
