Fuel / Temp Gauge - Not Accurate

[CWizard]

Just replace the temperature gauge. The entire assembly consists of the dash mounted dial, a long thin tube, and a sensing bulb (which goes into the intake), and there are no replaceable or adjustable components. Get a new one at Nisonger (Nisonger Instruments :: the exclusive Smiths U.S. Warranty & Service Center since 1949) or gaugeguys (APT Instruments International Inc). You could also send yours to Nisonger to be rebuilt, but you'll find the cost is about the same as a new one. And takes longer.
Good luck.

Thank you for the quick reply.

Off on a week of travel. I will check the fuel sending unit connections this weakend. Car has only 6K miles on it . . but is 15 years old.

I have read the voltage stabilizer dropped the voltage to 10V. . . I would think that turning on a fan motor would drop the amperage . . but not the voltage . . but I am certain the need for a voltage stabilizer was designed by much more experienced individuals than myself.

Thank you.

I thought the temp gauge was a capillary type of set up . . but wasn't 100% sure. If this is the case . . I would assume there is no relationship to the voltage stabilizer and I am dealing with two independent problems.

I didn't see any prices online . . or a way to order . . so I will place a call this week.
