Guest goodtoothdoc Posted July 30, 2012 Share Posted July 30, 2012 Help... Temperature guage stopped registering. Does this car have a temp sensor? Is guage itself bad? How do you replace it if that's what's needed? Thanks Clark G, goodtoothdoc@yahoo.com Link to comment Share on other sites More sharing options...
Gene Brink Posted July 31, 2012 Share Posted July 31, 2012 Not quite as easy as a newer car, Clark. Temperature gauge is part of a sealed unit consisting of a pressure gauge connected by a capillary tube to a vapor bulb. Shows temperature change as the sealed-in liquid expands as the engine heats thus moving the gauge needle. Not too much that can go wrong unless a leak in the system develops in which case no gauge function. They can be rebuilt - and if my memory cells are functioning believe there have been other chains about this so a search of the Buick forum should give you some ideas on how to best fix. Good luck.
