    Default Daria temp gauge jumping

    I have a 2005 Four winns and my temperature gauge was reading a little hot and my risers were cold so I changed out the gauge to a brand new one and then the new gauge started jumping around erratically so I called the company and they sent me a new gauge and the same thing is happening. I am plugged with wires going into the thermostat and I didnít make a difference at the gauge. Nuts and wires are all tight on the back of the gauge so I was wondering if anybody could shed some light on this

    Stop! Before you destroy your engine. Cool elbows does not mean your engine is not running hot. Erratic temp readings at the gauge shows that air is being pumped in with cooling water.

    What engine and drive do you have?

    BTW Faria is the company that makes the gauge.

    Yeah, you may want to hire a qualified Mechanic to look at this. He will have CDS or comparable scan tool to verify your engine temps and water pressure.

    Any chance it could be a ground wire somewhere? Where does the wire hook up in the engine compartment for the gauge?
