Hi
Any more details of the gauge, or which car it was originally fitted to ?
Most (but not all) senders are a simple temperature dependent resistor. The resistance at normal running temperature depends on the sender, and there is quite a choice. You also need the correct thread form, assuming a screw-in type. With luck, you should be able to find a sender that gives a more sensible reading.
Although it's possible to tweak the reading by adding fixed resistors, this is only really useful for a minor adjustment. If you attempt too much, you may end up with a needle that doesn't move very much over a wide temperature range.
