It moves up a little and then movesback down to nothing. Is it sommething to do with the thermostat.   Joey (Joey4420) Senior Member Username: Joey4420 Post Number: 556 Registered: 04-2003 Posted on Tuesday, February 10, 2004 - 02:12 pm:    If you are getting heat from the heater, then it may be the sending unit....if you get almost no heat, then probably the t-stat stuck open.   Rob Margis (Rovermonk48) New Member Username: Rovermonk48 Post Number: 19 Registered: 04-2003 Posted on Tuesday, February 10, 2004 - 11:06 pm:    Yeah I'm getting heat so I'll go and check on that and see if its the problem.

It could also be the actual sending unit, when I replaced mine my old one was covered in coolant crud!!!!
