One temp. gauge is sender attached to solid wire(copper/aluminum) Other unit is sender with electric wire to gauge. The rest of the gauges are all the same. | | | | | Joined: May 2005 Posts: 8,983 Sir Searchalot | | Sir Searchalot Joined: May 2005 Posts: 8,983 | Well as far as temp gauges it sounds like you have one mechanical and one electrical. One with a tube and one with a wire. They are best tested buy putting the "sender" part in water over a heat source and watch gauge compared to a thermometer in the water container. Take it to boil and back down while observing. The electric is more trouble: You can use a battery or a battery charger for the electric one while in the water. (submerge only the threaded portion).

What year head do you have?
The mechanical sender might need a brass bushing to fit into the head that used the electrical sender. Check the outer diameter of the sender bases.

Do both types of senders fit into that head, with no adapter?
The 1955-2nd Task Force Truck "mechanical" sender might have a wider diameter than the earlier mechanical senders. That would be interesting to know.

Not sure about the mechanical one. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | I would sure use the electrical gauge if possible. I was thinking the mech gauge used on 6 cyl. & the electric on v-8.
