Hey guys I am having some problems with my gauges. I got this cheap 4 in 1 gauge from eBay and it ended up being in Celsius. Well it began reading at maybe 80 degrees and went up from there when the engine was still cold. So I figured maybe the sending unit measures in Fahrenheit. So I bought another water temperature gauge. Forgot the brand it was I believe around 70 dollars. And installed it. And it's reading 280 degrees with the engine cold. But it goes up with temperature. Is there some kind of resistor I may need in the line to get it to work more accurately or is my sending unit screwed up?
